Articles
Long-form essays on Indian retail trading, quantitative research, execution science, and the institutional workflow. Written to match the depth of the Bharath Shiksha curriculum.
Preferential Allotments: The 90-Day Floor, the Lock-In and the Dilution Arithmetic
How a preferential allotment is priced in India, why its floor is set a month before the vote, the unaffected price allowed since May 2024, the lock-in, and the value moved from holders left out, computed and measured on the exchange's records.
Merger Arbitrage in India: The Spread, the Break Price and the Tribunal Clock
Merger arbitrage on Indian listed deals worked from first principles: the spread as a probability-weighted payoff, why cash and share-swap spreads pay for different things, the verified approval sequence and its clocks, six real schemes timed from their own filings, and why the break price is not the pre-announcement price.
Accrued Interest and Day Count Conventions in India: Which Instrument Counts Which Way
Accrued interest is the seller's share of the next coupon, and its size depends on the calendar: 30/360 for central and state government bonds, actual/365 for bills and overnight money, actual/actual with a 366-day leap year for listed corporate bonds.
AT1 Bonds in India: Perpetual in Law, Callable by Convention, Written Down First
Additional Tier 1 bonds are bank capital that is allowed to disappear.
Credit Ratings in India: Read the Migration Record, Not the Letter
A credit rating is an opinion on a SEBI-defined scale about timely payment, paid for by the issuer and silent on price. Agencies must publish how their categories migrate and default.
Corporate Bonds for Retail Investors: Face Value, Platforms and the Exit, Measured
SEBI cut the face value of privately placed corporate bonds to ₹1 lakh in 2023 and allowed ₹10,000 from July 2024 on a merchant banker condition it proposed relaxing in August 2026.
State Development Loans: Why They Yield More Than G-Secs, Measured
A state development loan yields more than a central bond of the same maturity.
BHARAT Bond Index: Ownership, Not a Guarantee, and the Spread It Paid
The Nifty BHARAT Bond indices pick AAA bonds of government-owned issuers, cap each issuer at 15 per cent and exclude any bond the government backs or services.
Target Maturity Funds and the Roll-Down: What Holding to the Date Pins, Measured
A target maturity fund holds bonds that all mature by one date, so its duration falls as the calendar runs and the yield at purchase becomes an approximate outcome for a holder to the date.
Debt Funds After the Tax Change: Section 76, the 65 Per Cent Test and the Break-Even That Moved
Debt fund units bought since 1 April 2023 are taxed at the slab however long they are held.
Bond Yields and Equity Valuation: The Discount Rate, the Yield Gap and the Premium Backed Out of Price
A bond yield reaches an equity price through the discount rate, but the yield gap sets a real earnings yield against a nominal bond yield.
The Repo Rate Is the Middle of a Corridor: How India's Overnight Rate Is Actually Set
India's repo rate is the middle of a 50 basis point corridor, not the price of overnight money. The standing deposit facility is the floor, the marginal standing facility the ceiling, and liquidity decides where the call rate trades.
Buying a Government Bond in India: Retail Direct, the Non-Competitive Bid and the Price You Pay
Retail Direct gives an individual a gilt account in the RBI's own ledger and a non-competitive bid in every government bond auction, filled at the weighted average of the winning bids, at or above the cut-off.
Treasury Bill Yields: Discount, Money Market and Effective, Computed From RBI Auctions
A treasury bill pays no interest: it is bought below 100 and repaid at 100.
The Yield Curve Is a Price List: Par, Spot and Forward Rates on India's Official Curve
FBIL's par curve for 16 September 2026 bootstrapped into spot and forward rates, the forward read as a break-even rather than a forecast, what the RBI corridor and a thin long end do to the curve's shape, and eight years of month-end curves and eleven of maturity bucket indices, measured.
Duration and Convexity, Computed: What a Yield Move Costs an Indian Bond Holder
Macaulay and modified duration computed rather than defined, the first-order price estimate and its error from 10 to 300 basis points, and the size of move at which convexity decides the loss.
Bond Price and Yield: The Discounting, the Inverse, and Clean vs Dirty Price
A bond's price is the present value of its payments and its yield is the one rate that makes that sum true, so each restates the other.
Risk Parity for Indian Equity and G-Secs: Equal Risk, Measured
Equal capital is not equal risk. Measured on NSE total return indices from October 2015 to September 2026, a 50:50 equity and G-Sec split put 93 per cent of its risk in equity.
Trade for Trade, Measured: What Compulsory Delivery Does to a Stock's Liquidity
A stock moved to trade for trade settles every trade by delivery, so netting ends and an intraday round trip becomes a short sale.
The Rights Entitlement Market: Its Price, Its Window and the Cost of a Lapse
A rights entitlement has its own ISIN and trades for a few sessions before the issue closes.
Taking Part in the Opening and Closing Auctions: What Happens to a Retail Order
What happens to a retail order in the pre-open and closing auctions: which orders each window accepts, when an order locks, what one clearing price means for a market order, where an unfilled remainder goes, and the 7 September 2026 change that moved market orders to the front of the pre-open queue.
T+1 Settlement Hour by Hour: Pay-in, Pay-out and the Sale of Shares Not Yet Delivered
The operational side of T+1 in India: pay-in by 10:30 to 11:00 on the next settlement day, sale money from 1:30 pm, bought shares in your demat at 3:30 pm.
Record Date and Ex-Date Under T+1: Who Is Entitled, and When
Entitlement to a dividend, bonus or split is decided by settlement, not by the trade date. Since 27 January 2023 the ex-date falls on the record date itself, except on settlement holidays, and the same-day segment is shut that day.
Delisting in India: Reverse Book Building, the 90 Per Cent Line, the Counter Offer and the Fixed Price Route
In a reverse book building the public shareholders bid and the acquirer pays the ask that carries it to 90 per cent of the counted shares.
Buyback Tender Offers in India: Entitlement, Acceptance Ratio and the Tax That Changed Again in 2026
A tender offer fixes the price and rations the quantity. The record date sets the entitlement, a 15 per cent reservation lifts the small shareholder ratio, and shares other holders leave unused are redistributed.
Price Bands Measured: The Spike at Every Limit, the Range That Slides, and the ETF Band Change of 7 September 2026
Measured on 2,337,297 NSE stock sessions from January 2022 to September 2026, each labelled with the band the exchange stated for it: fixed bands leave a spike at the limit and nothing beyond, derivative stocks leave neither, the index breaker fired on two days in thirteen years, and ETFs moved to dynamic bands on 7 September 2026.
Impact Cost Is the Real Spread: How the Exchange Measures It, and Why Volume Cannot
Impact cost is the percentage mark-up against the midpoint of the best bid and offer for a stated order size, computed separately for buying and selling.
Weekly Versus Monthly Expiries: What the Consolidation Actually Moved
Since 20 November 2024 each Indian exchange lists one weekly index option, and since 1 September 2025 expiries fall only on Tuesday and Thursday.
The Variance Risk Premium in India: India VIX Against the Volatility That Followed
India VIX measured against the volatility the broad index realised over the following 30 calendar days, 3,027 windows from 2014 to 2026: above it 82.6 per cent of the time, median gap +3.30 points, and a worst window that realised 22.8 times the variance priced.
Total Return vs Price Index: The Dividend Gap, Rebuilt and Measured
The headline index is a price return. Rebuilt two ways from the exchange's files and checked against the published total return index, the dividends it omits were worth 1.34 points a year over the decade to 18 September 2026.
Demonetisation as a Market Event, Measured by Sector
Measured on the exchange's own session files: in the five sessions after the 8 November 2016 announcement the broad index fell 5.06 per cent while sector indices ran from -20.23% to +9.75%, a spread wider than 99.6 per cent of five session windows since 2013.
March 2020 Measured: Circuit Halts, Margin Calls and the Forced-Selling Loop
The index circuit breaker fired twice in March 2020, at 9:20 am on 13 March and 9:58 am on 23 March.
Look-Ahead Bias From Corporate Actions: The Phantom Gap, Measured on Real Splits and Bonuses
Measured on 426 split and bonus ex-dates in the exchange's own files from 2022 to 2026: a one-session error in the adjustment date turns a flat breakout rule into an apparent winner, a back-adjusted minimum-price filter chooses stocks by their future, and the T+1 move put the ex-date on the record date, reversing the old one-day shortcut.
Survivorship Bias, Measured: What a List Chosen Today Adds to an Indian Backtest
Survivorship bias measured, not described: an equal-weighted buy and hold of 1,119 Indian company shares from 3 January 2022 to 18 September 2026, run on the survivors and on the full point-in-time list, differs by 3.6 to 10.5 percentage points.
Retail F&O Regulation in India, Measure by Measure: What Each Rule Targeted and What Changed After
SEBI's August 2026 study found 87.7 per cent of individual derivatives traders lost money in FY26, with losses of 91,685 crore rupees, 18 per cent below an FY25 figure the regulator itself restated.
How the Official Close Is Formed in India: The Auction and the Average
Since 3 August 2026 a stock with derivatives closes at the single price of a call auction run from 3:15 to 3:35 pm, while every other stock still closes on the average of its last half hour.
Evaluating a Chart Pattern Claim: Four Questions That Decide
A published chart pattern reliability figure is produced by a definition, a universe, a period and a search, and the figure moves when any of them moves.
Has the Return Distribution Changed? The Two Sample Test, Done Properly
The two sample distribution test assumes independent observations. Indian index returns do not have them, and the measured false positive rate is six times the nominal one. What the test can detect, what it structurally cannot, and why
Band Width and Volatility Cycles: Testing the Squeeze Claim
A volatility band's width is recent realised volatility rescaled by a known constant, which makes it a description of the present.
Calibrating a Trend Strength Indicator to Indian Index Data
What the average directional index actually computes, measured on 3,385 real Indian index sessions.
Institutional Flow Regimes: What the Published Numbers Measure
The daily foreign and domestic institutional flow numbers are purchase and sale values in the cash segment. They exclude derivative exposure entirely.
VWAP versus TWAP: Two Benchmarks, Two Schedules, and the Difference
VWAP and TWAP are each both a benchmark you are scored against and a schedule for slicing an order, and those are not the same object.
Iceberg Orders: What Slicing Hides, And What The Book Still Shows
Two different mechanisms are sold under one name in India. A disclosed quantity order is one order with its display truncated, so the whole size stays committed and the time stamp survives.
India VIX Zone Classification: The Measured Distribution
The real empirical distribution of India VIX across 3,048 exchange sessions, how to derive zone thresholds from it by a stated percentile rule instead of asserting round numbers, how long a zone actually lasts once entered, and the measured instability that limits what any classifier built this way can be used for.
Reproducibility: Publishing a Result Someone Else Can Check
Seed control, the data snapshot and the environment decide whether a number can be checked at all. The same code on the same data, run twelve times, is measured here moving by a fifth of the quantity it reports.
Outliers, Bad Ticks and the Cleaning Decisions That Change Your Results
Measured on 3,395 sessions of the broad Indian index: the same record gives a worst drawdown from 16 to 44 per cent and excess kurtosis from 0.2 to 22.2 depending only on the cleaning rule.
Continuous Futures Series: Three Stitching Methods and What Each One Invalidates
No futures contract trades for years, so every long futures chart is stitched from expiring contracts.
Adjusting a Price Series Correctly: Split, Bonus, Rights and Dividend Factors
The adjustment factor for splits, bonuses, rights and dividends, worked from NSE data. A rights issue needs the theoretical ex-rights price: across 170 NSE rights issues a ratio-only adjustment recorded a median ex-date move of +18.8%.
The Bhavcopy, Field by Field: What Each Column Measures, and the Close That Changed in August 2026
The NSE full security bhavcopy measured column by column across 1,164 sessions: the series code that decides what a row is, delivery netted inside each client code, turnover in lakhs, a derivatives file that counts contracts but reports open interest in shares, and a closing price that became an auction price for stocks with derivatives on 3 August 2026.
The Margin Shortfall Penalty, Computed
Margin adequacy is read from unannounced intraday snapshots, so a position that was funded when it was opened and funded when it was closed can still be short in between.
Stress Testing a Portfolio Against Historical Indian Events
How to select stress scenarios mechanically from the Indian record rather than from memory, reprice a stated book through each one, and read what the exercise shows that a volatility number cannot.
Sequence of Returns Risk, Computed on 164 Real Months
Reverse a real return series and the no-withdrawal outcome is identical to the last digit. Apply a fixed withdrawal and one run survives while the other is exhausted twelve months early.
Tail Risk, and Why Standard Deviation Understates It
A standard deviation summarises the middle of a record and is nearly silent about its edges.
Kelly, Fractional Kelly and Estimation Error
The fraction that maximises the expected logarithm of capital is a closed form, and it is unusable, because it needs a quantity that cannot be measured at realistic sample sizes.
Volatility Targeting and Drawdown: What the Rule Measurably Did
Volatility targeting scales exposure inversely to trailing realised volatility.
Correlation-Adjusted Position Sizing, Measured on Indian Sector Indices
Portfolio risk is a quadratic form, so correlation enters the sizing arithmetic directly.
Portfolio Heat: The Total Open Risk You Are Carrying Right Now
Portfolio heat is the loss if every open position reached its exit at the same moment. The word doing the work is 'same'.
Good Till Triggered Orders: Where the Instruction Actually Lives, and What Breaks When It Fires
An instruction that survives the close cannot be sitting at the exchange, because the regular order book takes only day and immediate-or-cancel validity.
Stop-Loss Market or Stop-Loss Limit: What Each One Actually Guarantees
A stop-loss market order guarantees that you get out and says nothing about where. A stop-loss limit order guarantees where and says nothing about whether.
Queue Position: What Price Time Priority Really Ranks, And What A Modification Destroys
Orders at one price are a queue, ranked by time of arrival, and the exchange matches from the front.
Delta Is Not a Probability, and the Difference Is Computable
Delta and the chance of finishing beyond the strike are two different expressions whose arguments differ by the total volatility to expiry.
The Forward Price Is Not a Forecast: Cost of Carry and What the Basis Contains
The forward price is the spot price compounded at the cost of carrying the position, less anything the holder receives for holding it. Nobody forecast anything.
Put-Call Parity as an Arbitrage Band: Synthetics, Conversions and the Indian Cost Stack
Put-call parity derived from two portfolios, the synthetic long and short and what they are really for, and why European exercise makes it one relation that costs turn into a band.
Pin Risk at Expiry, Quantified: The Position You Cannot See Until the Market Is Shut
A contract that settles a few paise from its strike decides, after the close, whether the holder of a short position owns nothing or owns a delivery obligation worth several lakh.
Gamma and the Cost of Short Convexity: What a Gap Actually Does to a Short Option
Gamma is the rate of change of delta, so a short option position gets shorter as the market rises and longer as it falls.
Vega Across the Term Structure: Why a Calendar Spread Is Long a Spread, Not a Level
Vega scales with the square root of time, so a far dated option responds far more to a change in volatility than a near dated one.
Theta Is Not a Daily Rent: Where Option Time Decay Actually Concentrates
Option time value moves with the square root of the time remaining, so decay per session accelerates instead of running flat.
Cross Margining Across Cash and Derivatives: What Qualifies, How the Offset Is Computed, and Why a Hedged Book Can Still Pay Full Margin
A long cash position and a short futures position in the same underlying are substantially offsetting, and charging full margin on both overstates the risk. Cross margining is the risk model that says so.
Spread Margin Benefit and the Expiry Day It Disappears: How the Offset Is Computed, and Why the Requirement Rises Without the Position Changing
A margin benefit on a spread is what a scenario grid produces when it revalues a portfolio instead of its legs.
Position Limits in Indian Derivatives: Client, Member and Market Level, and Which One Actually Stops You
Indian equity derivatives carry three separate ceilings on one position: the client limit, the trading member limit and the market wide limit.
Benchmarking a Strategy Against the Right Null
A test compares a result against what the alternative would have produced. The alternative is a choice, and choosing a weak one keeps the appearance of a test while removing its content.
Maximum Drawdown Is a Sample Statistic
Maximum drawdown is the maximum of a set of declines, so it is an extreme value statistic and it grows with the length of the record even when nothing about the process changes.
Correlation Is Unstable, Measured on Indian Sector Indices
A correlation is not a property of two markets. It is a number produced by a window length and a period, both of which you picked.
Stationarity, and Why a Price Series Is Not Stationary
Stationarity is the assumption that the process generating the data is not itself changing.
How to Read a Published Strategy Claim
A result is a number attached to a search, and the search is the part almost never reported.
Transaction Cost Modelling That Does Not Flatter You
A backtest prices the charges it can look up, sometimes allows for the spread, and almost never models impact. The omission is largest exactly where the strategy looks best.
Regime-Conditional Performance: Which Market State Actually Paid
A single performance figure for a system is a weighted average of its behaviour in each market state, and the weights are nothing more sacred than the historical frequency of those states.
Walk-Forward Efficiency: What the Ratio Measures, and How It Is Gamed
Walk-forward analysis re-optimises on a training window and scores on the untouched window ahead of it. Walk-forward efficiency divides the second by the first.
Bootstrap Confidence Intervals on an Equity Curve: The Width Nobody Reports
A backtest produces one path. The bootstrap asks what the family of plausible paths looks like given the same return distribution.
How Many Trades Before You Can Tell an Edge From Luck
A small edge needs an enormous sample, and the relationship is quadratic.
The Deflated Sharpe Ratio: What It Does to a Good-Looking Backtest
A Sharpe ratio is an estimate with a standard error set by sample length and, to a smaller degree, by skew and fat tails.
Multiple Testing and Strategy Selection: Why the Best of Fifty Backtests Is Probably Noise
Selecting the highest Sharpe from a set of candidate rules changes what the number measures. On simulated data with no edge whatsoever, the best of fifty three-year backtests clears an annualised Sharpe of 1.0 in 88 percent of runs.
Short Delivery and the Auction: Why a Failed Seller Pays a Price They Did Not Choose
A seller who does not deliver on time does not simply reverse the trade.
The F&O Ban Period: A Limit on the Security, Not on Your Account
The market wide position limit caps the aggregate open interest in one stock's derivatives across every participant, not any single trader's position, which is why a ban arrives without warning and without anything changing in your account.
ASM and GSM: The Surveillance Frameworks, and What a Stage Change Does to a Position You Already Hold
The Additional Surveillance Measure responds to how a security is traded and escalates margin.
The Pre-Open Call Auction: Why The First Traded Price Is Not The Open
The opening price is computed, not negotiated.
The Open Offer Price Is a Formula, Not a Negotiation: The Floor, the Look-Back Windows, and Why It Is So Often Below the Screen
The three routes into a mandatory open offer under the takeover regulations, the price references that set the floor and the windows each of them looks back over, and the two calendar months between the day the price is fixed and the day the tendering window opens.
Demerger Cost Base: The Split Is By Book Value, Not By Market Price
When a listed company separates a business, the original cost of acquisition does not stay with the parent.
Side-Pocketing In Debt Funds: The Run It Stops, And Who It Actually Protects
Side-pocketing splits a debt scheme into a main portfolio that keeps trading and a segregated portfolio holding the impaired instrument, frozen. It is reported as a fund trapping your money.
Exit Load and the Tax Clock: Two Calendars That Were Never Set to Agree
An exit load is not a fee the fund house keeps. Regulation 51A has required the whole of it to be credited back to the scheme since 2012, so the investor who leaves compensates the investors who stay.
Which NAV You Get: The Cut-Off Still Exists, But Realisation of Funds Decides the Price
Since 1 February 2021 the applicable NAV on a mutual fund purchase in India follows the later of two timestamps: when the valid request was received, and when the funds became available for utilisation by the scheme.
Direct Against Regular: The Commission Is The Gap, And It Is Taken Before You See The NAV
A regular plan and a direct plan of the same scheme hold identical securities run by the same manager.
The Expense Ratio Is Taken Daily, Falls in Slabs, and Stopped Meaning What It Meant on 1 April 2026
A scheme's expense ratio is accrued every day on net assets and deducted before the NAV is declared, so it never appears as a debit. The permitted rate falls in marginal slabs as the scheme grows.
The Small-Cap Stress Test: What Days To Liquidate Measures, And The Three Assumptions That Make It A Floor
Mid-cap and small-cap schemes must publish, in a standardised fortnightly format, how many days it would take to liquidate 25 and 50 percent of the portfolio, alongside investor concentration, market cap split, cash, standard deviation, beta, price to earnings and portfolio turnover.
Gifting Shares in India: The Cost Base Travels, and Clubbing Sends the Income Home
A gift of listed shares is outside the capital gains charge for an individual or HUF donor, but the donee inherits the donor's cost and the donor's holding period, so the embedded gain travels intact.
GST Inside the Trading Cost Stack: The One Charge a Trader Can Never Reclaim
GST at 18 percent sits on the service lines of a contract note and never on Securities Transaction Tax or stamp duty. Every other business recovers it.
The Regime Choice With Business Income: A Door That Opens Once, Not Once A Year
A salaried taxpayer chooses between the two tax regimes afresh every year.
NRI Tax on Indian Market Income: Same Rate as a Resident, Deducted at Source, and the Refund You Wait a Year For
Residential status is a day count under section 6, not a passport question.
Dividend Tax in India: Taxed in Your Hands at Your Slab, and the Last Deduction Was Withdrawn for Tax Year 2026-27
Dividend moved from a flat company-level levy to taxation at the shareholder's own slab rate in 2020.
AIS and TIS for Traders: Gross Reported Values, and Why Feedback Never Deletes an Entry (India)
The Annual Information Statement carries gross transaction values filed by depositories, registrars, banks and companies, never computed income, so a trader's figures look enormous and correctly do not match a broker profit and loss statement.
What a Trading Business Can Deduct: Section 37(1), the Capital Line, and the Act That Replaced It
The deductibility test for a trading business, worked limb by limb. Revenue against capital is the line that costs money, not allowed against disallowed.
Advance Tax for Traders: The Cumulative Ladder, 234C Interest, and the Statute That Changed on 1 April 2026
The four advance tax dates carry cumulative targets of 15, 45, 75 and 100 percent of the full year's liability, and deferment interest crystallises at each date whether or not the year ends fully paid.
Set-Off and Carry-Forward of Trading Losses in India: Two Statutes, One Trader (2026)
A non-speculative business loss can be set off against speculative income. A speculative loss cannot be set off against non-speculative income.
F&O Turnover Is Not Contract Value: The ICAI Method, and the Edition That Changed It
Turnover for futures and options is the absolute sum of favourable and unfavourable differences, never the notional value of the contracts.
Section 44AD for Traders: Why Intraday Is Barred and F&O Is Not (India)
Section 44AD(6) excludes speculative business. Intraday equity is speculative under section 43(5), so it is barred from the presumptive scheme outright, while F&O is non-speculative business and is not.
Demat vs Trading Account in India: What's the Difference? (2026 Guide)
A demat account holds your shares. A trading account routes your orders. Most retail Indians conflate the two. Here is the clean distinction and why it matters.
Circuit Limits in Indian Stock Market: 10%, 15%, 20% Halts Explained
Why does the market halt at 10%, 15%, or 20%? Who decides? When did the rules last change? A clean explanation of India's circuit-breaker framework, no jargon.
NSE vs BSE: Difference, History, and Which Exchange Matters in 2026
BSE is older. NSE is bigger by volume. Both list mostly the same large-caps. Here is the clean history, the structural differences, and when the choice actually matters.

Why Most Indian Retail Traders Lose Money: What the SEBI Data Actually Says
Survey of SEBI's 2024 retail-trader study and broker disclosures: 89-93% lose in F&O. We unpack the methodology, the cohort, and what the numbers do and do not prove.
Trading Journal Practice: Why Every Serious Trader Writes Things Down
A journal is not a spreadsheet template. It is the loop that turns experience into edge. Here is why elite traders journal, what they capture, and how the habit compounds.
Position Sizing for Indian Retail Traders: First Principles (No Math Required)
Before you reach for a position-sizing formula, understand the four ideas underneath it: capital at risk, ruin, asymmetry, and replenishment. The concept comes first.

Retirement Planning for Active Indian Traders: The Three-Bucket Framework
Active trading is feast-or-famine income. The institutional retirement framework adapts poorly to traders. The three-bucket structure that handles variable income, tax inefficiency, and the specific risks of trading capital.
Choosing a Broker in India for Active F&O Trading: The Decision Framework Beyond Price
Brokerage cap is the obvious lever. Platform reliability, API access, customer support quality, and fund-settlement speed matter more for serious retail trading. The eight-point comparison framework.
F&O Margin Maintenance for Indian Retail Traders: Span, Exposure, and the Six Common Pitfalls
SPAN + Exposure margin, peak margin enforcement, mark-to-market mechanics, and the six failure modes that produce broker calls and forced square-offs.
Oil Prices and Indian Equity: The Asymmetric Drag and the Sector Hedges

USD/INR and Indian Equity Markets: The Correlation, the Sectoral Asymmetry, and the Trades
INR weakness benefits IT and pharma exporters; INR strength helps importers and refiners. The structural sector mapping, the regime-dependent correlation, and the Indian retail trades that follow.
The Gold-Silver Ratio for Indian Traders: A Macro Indicator and a Trade in Itself
The ratio between gold and silver prices has signalled monetary regime shifts for over a century. The Indian-market mechanics, the 80-mark threshold, and the retail-accessible mean-reversion trade.
Dollar-Cost Averaging vs Lump-Sum Investing in Indian Markets: What the Data Actually Shows
The DCA vs lump-sum debate has clear answers in academic research. The Indian-market data largely confirms the global pattern with one important caveat. The framework, the math, and the behavioural override that justifies DCA anyway.
Smart Beta in India: Factor ETFs, the Evidence, and What Retail Investors Should Actually Buy
Quality, low-volatility, momentum, value, Indian smart-beta ETFs promise factor-tilted returns at index-fund cost. The published evidence, the Indian-market caveats, and the realistic expectations.
Wyckoff Point and Figure Charts on Indian Stocks: The Forgotten Method That Filters Noise
Point and figure charts strip out time and noise to reveal price structure. Combined with Wyckoff's accumulation-distribution framework, the method is one of the most under-used technical tools in Indian retail trading.
Sector Rotation Strategy on Indian Equities: The Macro Cycle, Relative Strength, and the Three-Sector Portfolio
Indian sectors lead and lag through macro cycles in identifiable patterns. The relative-strength framework, the macro signal, and the rules-based three-sector portfolio retail traders can run.
