New York (CNN Business) US stocks rebounded sharply on Monday, with the Dow logging its biggest point gain in history.

The Dow also recorded its worst one-day point drop in history on Thursday.

"If [the market is] priced to perfection and then something indicates that the perfection is a pipe dream, prices will come off," said Brad Cornell, emeritus professor of finance at UCLA, of last week's selloff. Prices are much more reasonable now, he added.

But Monday's rebound was strong. After a sharply higher open and some flipping between gains and losses mid-morning, stocks moved solidly higher.
