Bull Market vs Bear Market

A bull market trends up and feeds optimism; a bear market falls 20% or more from recent highs and saps confidence.

A real-world scenario

In 2020 the S&P 500 fell 34% in five weeks — a textbook bear — then recovered all of it within six months and kept climbing into 2021. Investors who sold at the bottom on the logic that “a bear means more pain ahead” missed the fastest recovery on record. In 2022 the opposite happened: the index fell 25% over the year, and every “bottom-fishing” rally failed until late in the cycle. The lesson is that the bull-bear label is descriptive, not predictive, and the only reliable strategy is one that survives both.

Why it matters

Knowing the regime helps set expectations for risk and patience.

Common confusion

Start and end dates are only clear in hindsight; calling tops or bottoms is guesswork.

Worked example

How investors use it

Do not trade on the label. A disciplined investor holds through both regimes with a plan sized to their tolerance, using corrections to rebalance rather than to panic.

Key takeaway

Bull and bear are descriptive labels assigned in hindsight, not predictive tools for what happens next. A 19% drop and a 21% drop feel identical while they are happening, and rallies inside bear markets can fool even experienced investors. The profitable response is not to trade the label but to hold a plan sized for both regimes, using corrections as rebalancing opportunities. Markets recover from most downturns, but only if you are still invested when they do.
