3 August 1932: The Dow jumps 9.5 percent in a day

Less than a month after the Depression low, the Dow surged about 9.5 percent in one session, one of the largest percentage gains in its history. Short sellers rushed to cover, and General Motors helped spark the rally by maintaining its dividend despite thin earnings. Huge up days are common in bear markets and near bottoms, which is exactly why investors who jump out after a crash often miss the recovery.

The lesson: The best days often cluster near the worst ones; sitting out risks missing the rebound.

What it meant for investors

We start the clock at the start of 1990, the first year in our price data after the event. That is 19.4 times the money, but $0 less than a plain index fund made over the same years.

What S&P 500 index fund teaches: Owning the whole market removes the risk of picking the wrong company but not the risk of a lost decade, so time horizon matters as much as diversification.
