Wall Street rumbled to the edge of a bear market Friday after another drop for stocks briefly sent the S&P 500 more than 20% below its peak set early this year.
The S&P 500 index, which sits at the heart of most workers’ 401(k) accounts, was down as much as 2.3% for the day before a furious comeback in the final hour of trading sent it to a tiny gain of less than 0.1%. It finished 18.7% below its record, set on Jan. 3. The tumultuous trading capped a seventh straight losing week, its longest such streak since the dot-com bubble was deflating in 2001.
