Stock Movers

Today’s biggest winners and losers in the stock market, a look at the notable movers:
On this episode of Stock Movers:
- Nvidia (NVDA) stock had its worst week in more than 18 months, with its share price falling 13% over the last five trading days. The stock’s losses erased more than $570 billion in market value, a loss greater than the market value of 96% of stocks in the S&P 500. At least 13 analysts covering Nvidia have downgraded shares this month, with 15 hold ratings, as Wall Street analysts have shifted to wait-and-see mode in the wake of the scandal.
- A global outage has hit Microsoft’s (MSFT) Outlook, Teams, and Copilot AI assistant, impacting users across more than 70 countries. The stock was down Friday, on track for its third fall of 2% or more in the past four trading days. Engineers have been working to fix the problem for more than 15 hours, with the company reporting “early stabilization” and capacity improvements in its most recent update.
- CoreWeave (CRWV) is in talks with banks to raise at least $4 billion through an investment-grade loan to help the company borrow more cheaply to finance its artificial intelligence chip capacity. The loan will be backed by a contract with Meta Platforms Inc. and may be sold at a yield of 7% to 7.5%, which is about half the yield on where its junk bonds currently trade. The new loan will have a six-year maturity and requires the borrower to pay down at least some of the debt during that time, and will be secured by the GPUs involved in the Meta contract as well as other assets.
