Federal Reserve Chair Jerome Powell's latest comments are dragging down sentiment on Wall Street. In prepared remarks for two appearances this week, Powell said that interest rates may need to move higher for longer, and emphasized that the central bank is "very far" from getting inflation under control. In response, the Dow Jones Industrial Average (DJI) is down 330 points, while the Nasdaq Composite Index (IXIC) and S&P 500 Index (SPX) sit deep in the red as well.

Snap Inc (NYSE: SNAP) is 5.3% higher to trade at $12.28 this afternoon and seeing high options volume.
