The S&P 500 briefly entered bear market territory on Monday, before the index clawed back some of the losses to end the day nearly flat and 17.6 percent below its February 19 high. A bear market is typically defined as a drop of 20 percent or more from and index's latest high - a fate that the S&P 500 avoided, at least for now. On Tuesday, stocks rebounded further, recovering some of the losses incurred after Trump's "Liberation Day" tariff announcement. Hopes of possible tariff deals were enough to stop the selloff for now, but markets will likely remain volatile for as long as uncertainty over future tariffs prevails.
