Bear markets and a truth about investing

The stock market continues to trend lower.

Before rallying on Friday, the S&P 500 had a closing low of 3,930.08 on Thursday, down 18.1% from its all-time closing high of 4,796.56 on January 3.

If you consider the intraday market action, the S&P traded as low as 3,858.87 on Thursday, down 19.9% from its intraday high of 4,818.62 on January 4.

Technically speaking, stocks don’t enter a “bear market” until prices are down at least 20% from their highs. And for most market watchers, this calculation is based on closing prices. Frankly, this is all silly semantics about round numbers and rounding errors.

Any way you look at it, the stock market is down a lot.

Learning from history

We could debate all of the ways that the present day is and isn’t like history’s bull and bear markets, but that’s unlikely to end with a definitive conclusion.1 Nevertheless, let’s do a quick review of historical market performance.

Technically, we’re in year three of a bull market that began on March 23, 2020.

Ryan Detrick, chief market strategist at LPL Financial, reviewed the history and found that three of the 11 bull markets since World War II ended in year three. So from the perspective of duration, it wouldn’t be too unusual for stocks to be in a full-blown bear market some time before March 2023.

On the matter of duration, history’s stock market corrections (i.e., when the stock market falls by more than 10% but less than 20%) have had an average length of 133 days from market top to market bottom, according to data compiled by Detrick.

The current correction has run for 131 days as of Friday, which makes it pretty close to average assuming the market inflects upward soon.

And since we’re very close to being in a technical bear market, now is a good time to talk about history’s bear markets. Ben Carlson, director of institutional asset management at Ritholtz Wealth Management, reviewed the historical data.

Since 1950, the average bear market lasted 338 days (with a range of 33 to 929 days) and saw the S&P 500 fall an average 30.2% (with a maximum decline of 56.8%).

It’s worth noting that many — but not all — bear markets came with economic recessions. And as you might expect, the bear markets amid recessions tended to be worse.

Carlson observed that since 1929, recessionary bear markets lasted an average 390 days peak to trough, with stocks falling an average 39.4% during that period. Meanwhile, non-recessionary bear markets lasted an average 202 days with stocks falling an average 26.1%.

This is what investors signed up for

When talking to novices about investing in the stock market, I try to make it a point to say that you can get smoked in the short-term. In fact, TKer Stock Market Truth No. 2 is literally: “You can get smoked in the short-term.”2
