What is the difference between a bull market and a bear market?

The names describe how each animal attacks. A bull thrusts its horns upward, an image for rising prices; a bear swipes its paws downward, an image for falling prices. A bull market therefore means a broad, sustained uptrend, and a bear market a broad, sustained downtrend.

Both terms describe the overall market mood and direction over weeks, months or longer — not the wiggle of a single session. A single down day in a rising market is not a bear market, and a single up day in a falling one is not a bull market.

In a bull market, higher highs and higher lows tend to form, dips are bought, and optimism builds; broad indices such as Nifty and Sensex grind upward over time. In a bear market, lower highs and lower lows tend to form, rallies fade, and pessimism dominates as the index trends down.

Bear phases are often faster and sharper than bull phases — fear tends to move prices more abruptly than optimism. A long, steady climb can be undone by a comparatively short, violent decline, which is one reason risk management matters across both phases.

A widely cited guide treats a decline of about 20% or more from a recent peak as a bear market, and a sustained recovery of similar scale as a bull market. A smaller pullback of roughly 10% within a rising market is usually called a correction rather than a bear market.

These thresholds are conventions, not strict laws, and they are clearest in hindsight. Within a bear market there can be sharp bear-market rallies that look like recoveries but fade; within a bull market there are corrections that look alarming but resolve upward. Direction is judged over time, not from a single swing.

Traders gauge the prevailing phase using the broad benchmarks — the structure of highs and lows on the Nifty or Sensex, the slope of longer-term moving averages, and how the index behaves around support and resistance. An index making higher highs above a rising average suggests a bull phase; one making lower lows below a falling average suggests a bear phase.

Identifying the phase is about reading what the market is doing, not predicting what it will do next. The phase can change, and confirmation comes over time as the pattern of highs and lows shifts.

The prevailing phase shapes how many traders think about risk and approach. Strategies that lean on buying dips can work in a bull market and struggle in a bear market, where rallies fade. Recognising the broad direction helps a trader set realistic expectations and apply appropriate risk control rather than fighting the dominant trend. Neither phase removes the need for stop-losses and disciplined position sizing.
