Key Takeaways:
- A bear market is typically defined as a 20%+ decline from a recent high
- Bull markets have historically run considerably longer than bear markets
- Neither term predicts what happens next — they describe what already occurred
The Technical Definitions: A bull market is a sustained period of rising prices with investor optimism and growth. A bear market is typically a decline of 20%+ from a recent high, sustained over a meaningful period.
Why “20%” Became the Standard: No law set this threshold — it emerged as a convention because declines in that range have historically reflected a genuine shift in sentiment and outlook, not routine volatility.
How Long Each Typically Lasts: Bull markets have historically run considerably longer than bear markets, which is a major reason buy-and-hold has historically rewarded patience over market-timing.
What Drives Each: Bull markets: growth, rising earnings, easy credit. Bear markets: recessions, credit crises, rate shocks, or a bubble deflating.
The Investor Takeaway: Neither term tells you what happens next — they describe what already happened, useful for context rather than prediction.
