2.1.3 Bull Market vs Bear Market

Two words for market mood

There is no official, universal trigger for either label, though a fall of 20% or more from a recent high is a commonly used rule of thumb for a bear market. What matters more than the exact threshold is understanding that both terms describe a phase, not a destination. Every bull market eventually ends, and every bear market in history has eventually ended too.

India has lived through several clear cycles. The 2003-2008 bull run took the Sensex from roughly 3,000 to over 20,000; the 2008-2009 bear market erased more than 60% of that in under a year. The dot-com crash of 2000-01 and the sharp COVID-19 fall of March 2020 are other examples. In every case the market eventually recovered and made new highs, though recovery time ranged from a few months to several years.

Why the labels can mislead

Calling a period a bull or bear market is easy in hindsight and far harder in the moment. Many investors only recognise a bull market once it is well underway, after much of the gain has already happened, and only recognise a bear market once the fall is largely done. Reacting to the label after the fact tends to produce the opposite of the intended result.

A particularly damaging pattern is selling in a bear market and waiting for "clarity" before returning. Markets typically recover well before the economic news improves, because prices reflect expectations about the future rather than a report on the present. Investors who sold during the March 2020 crash and waited for positive data missed a rally that recovered the entire fall within months. The emotional logic of waiting for safety is understandable; its financial cost is consistently high.

What actually matters for a long-term investor

For someone investing for a goal ten or twenty years away, a bear market along the way is close to a certainty rather than a risk to be avoided entirely. The practical response is not to try to predict the next bull or bear phase, but to hold an allocation that can survive a bear market without forcing a panicked sale, and to keep contributing through both phases rather than trying to time entries and exits.

A running SIP has a structural advantage here. When prices fall, each instalment buys more units, and when the market recovers those extra units bought cheaply amplify the rebound. A SIP that runs through a bear market and its recovery often ends up better off than one that runs through a steady climb, precisely because of the units accumulated at depressed prices. That is not a reason to hope for bear markets, but it is a strong reason not to stop investing during one.
