Don't miss

Nvidia’s board adds $150 billion to its share-repurchase authorization, bringing the remaining total to $235 billion.

The brief

Nvidia led the market roundup with a 2% gain after its board authorized another $150 billion for share repurchases, leaving $235 billion in the program.

The buyback is notable not only for its size but also for what it signals about Nvidia’s confidence, even as the discussion touches on possible Chinese purchases of its chips.

Northern Star rejected Gold Fields’ $27.1 billion takeover proposal, saying the offer undervalued the precious-metals miner and sharpening the debate over deal pricing.

Roblox moved lower after Jefferies downgraded the stock, arguing that its recent rally may overstate the company’s future bookings prospects.

Together, the movers frame a market split between Nvidia’s aggressive capital returns and growing scrutiny of valuation, strategy, and expectations elsewhere.
