A bear market of that magnitude is rare—according to Yardeni Research, only one other bear market since 1929 has been worse. (That was between 1930-32, when the S&P 500 lost 83% of its value.) However, Investors should pay attention to the magnitude of losses, perhaps more so than their frequency, because of the time it takes to recover from these kinds of extreme losses.
In the case of the last bear market, it took around four years for the S&P 500 to make up all of its lost ground. Add to that the 517 days from peak-to-trough of the bear market itself, and you get a total of five-and-a-half years of time lost trying to reclaim market value.
Lessons Learned
But the same lesson applies for time spent trying to recover from losses. Investors tend to think about market risk in terms of lost value, but the loss of time is also an important consideration. At Potomac, we like to emphasize the lesson of the “catch-up game”—meaning it takes a gain greater than an investment loss to recover fully from a decline in value. (This is illustrated in the table below.)

Where’s the Bear?
We mentioned earlier that the frequency of large losses or bear markets may not be as important as the magnitude of these losses. However, investors can be influenced by the frequency of losses or increased market volatility. After a period of calm, like the one we experienced last year in the equity market, investors may become too complacent about losses or volatility.
The current bull market just turned nine earlier in March, and it’s only been surpassed in length and cumulative return by the 12-year bull market of 1987-2000. While stocks have risen over 300% during this nine-year period, it hasn’t been a completely smooth ride. In this bull market there have been six corrections (market losses of 10% or more), most recently in February when stocks dipped over fears of inflation and higher interest rates.
Corrections occur more frequently than bear markets. Since World War II, stocks have corrected every 2.8 years, according to S&P Dow Jones Indices. Bear markets have occurred more often than many investors may think—every 4.8 years since WWII. (See chart below.)

Containing Major Losses is Key
Market returns can be lost more easily than they can be gained. So, the key to successful investing over the long term is to contain major losses that take too much time or too much exposure to volatility to recover from.
