Monday could mark the end of the Nasdaq Composite's bear market and the start of a new bull run.

The tech-heavy index was up more than 20% from its April 8 low, which would end the bear market that began roughly a month ago. At 25 trading days, it's on pace for its shortest bear market since April 2020, when a bear market lasted 22 trading days, according to Dow Jones Market Data.

The Nasdaq suffered the most of the big three indexes as tariffs sent traders fleeing riskier assets, including highflying AI bets and Magnificent Seven stocks.
