Smooth Air and Turbulence. Bulls and Bears.
Updated: Jan 18, 2022

Some days are smooth and clear, and some days not so much. Some days are definitely more fun than others. While we find weather quite unpredictable, the same can be said for the stock market. The one thing we know with the markets is that we'll have Bull and Bear markets. Figure 1 below depicts nearly a century of Bull and Bear market reflected in the S&P 500 returns.

What can we take away from this data?
Stock returns are volatile, but nearly a century of bull and bear markets shows
that the good times have outshined the bad times.
• From 1926 through 2020, the S&P 500 Index experienced 17 bear markets,
or a fall of at least 20% from a previous peak. The declines ranged from —21%
to —80% across an average length of around 10 months.
• On the upside, there were 18 bull markets, or gains of at least 20% from a
previous trough. They averaged 54 months in length, and advances ranged
from 21% to 936%.
• When the bull and bear markets are viewed together, it’s clear equities have
rewarded disciplined investors.
