The bell is bringing an end to the training day at the NYSC, the cast of HBO's industry, and at the NASAC ethos ringing the bell. Welcome to closing bell overtime line from Studio B at the NASAC market site. I'm Melissa Lee along with Mike Santoli. Sox mostly lower today, the doubt with a small gain. The S&P 500 down about a quarter of a percent. The NASAC down about 1 percent, breaking a six-session winning streak. is, despite a gain for META, even as it says it is going to keep on spending, the decline all about Microsoft, having its worst day since the COVID pandemic, and it's having a ripple effect on names like Corweave and Oracle.
