Bear Market
A bear market describes a period when prices across a market or a broad group of assets are falling significantly over a sustained stretch of time, not just a bad week or two. The term is most often applied to stock indexes, like the S&P 500 or Nasdaq, but it can also describe a bear market in bonds, commodities, or a specific sector.
The common shorthand definition traders use is a decline of a certain size, often cited as around 20%, from a recent high. That number is a widely used convention rather than a law of physics, and different commentators, index providers, and news outlets sometimes use slightly different thresholds or timeframes to declare one. What matters more than the exact cutoff is the underlying idea: broad, persistent pessimism pushing prices down, usually tied to worries about the economy, corporate earnings, interest rates, or some external shock.
The nuance that trips people up is that a bear market is not the same as a crash or a single sharp drop. A crash can happen in days; a bear market typically unfolds over months or longer, with rallies along the way that can fool people into thinking it is over. Bear markets are also not the same as a "correction," which is a smaller, shorter pullback that doesn't reach the size or duration usually associated with a full bear market.
It's worth remembering that "bear" and "bull" are directional labels for sentiment and price trend, not technical trading terms tied to a specific mechanic. A bear market can exist in an individual stock, an entire index, or an asset class, and the label is usually applied only in hindsight or through informal convention, since there's no single regulator that officially declares one.
This term depends on a rule or threshold that changes over time, so no specific figure is quoted here. The commonly cited '20% decline' threshold for defining a bear market is a market convention, not a fixed rule set by a regulator, and different sources apply it differently (some also require a minimum duration, e.g. two months). A human editor should confirm what percentage and duration figure, if any, TrueTrader wants to state as the standard convention, and cite a specific source (e.g., a major index provider or financial data provider) rather than presenting it as an official rule.
Day traders care because bear markets tend to bring higher volatility, faster and sharper reversals, and a shift in which strategies work, so risk management and position sizing often need to be adjusted compared to calmer, trending-up conditions.
Suppose the S&P 500 peaks at 5,000 in January and by October has fallen to 3,950, a drop of 21% from the high, with the decline happening steadily over those ten months rather than in one sharp move. Financial media would likely start referring to this as a bear market, even though the index bounced 5% higher in March before continuing lower.
