The stock market is trying to stage a rebound, but it’s struggling to hold onto even modest gains.

The S&P 500 was up 0.4% roughly 20 minutes into Friday’s session. About 330 of the index’s members were rising. The index is bouncing right around its 200-day moving average of 5733.01. That level has provided support for the market all week amid uncertainty swirling around tariffs and the path forward for the economy.

The Dow was up just 100 points. The Nasdaq Composite rose 0.4%. All three indexes opened lower, bounced, fell, and are bouncing again.
