Yesterday gave a great example of what I meant in Friday’s post when I said the stock market was not crashing. For those who missed it, the U.S. markets dropped sharply during the day, with the Nasdaq down almost 5 percent on the day, only to rebound at day’s end and land in the green. This kind of reversal is rare and signaled that—at the depths of the decline yesterday—a number of investors saw enough value in those prices to step in and buy.
