India, April 7 -- Following the nosedive seen over the two previous sessions, stocks saw substantial volatility over the course of the trading day on Monday. The major averages spent the day swinging back and forth across the unchanged line before eventually closing mixed.

While the tech-heavy Nasdaq inched up 15.48 points or 0.1 percent to 15,603.26 after plummeting by more than 5 percent in early trading, the S&P 500 dipped 11.83 points or 0.2 percent to 5,062.25 and the Dow slid 349.26 points or 0.9 percent to 37,965.60.

Stocks initially extended the sell-off seen over the two previous sessions amid ongoing concerns about the impact of President Donald Trump's new tariffs and retaliatory moves by U.S. trade partners.
