Don't miss

Nvidia’s newly authorized additional $150 billion share-buyback program anchors the episode’s market discussion.

The brief

Nvidia leads the session with a 2% gain after authorizing an additional $150 billion for share repurchases, while potential Chinese demand for its new AI chip adds support.

The report then turns to mining consolidation: Northern Star Resources rejects Gold Fields’ $27.1 billion takeover offer as precious-metals miners decline.

Roblox shares move lower after Jefferies downgrades the company, citing bookings expectations that had become overly optimistic.

Together, the moves show how capital returns, geopolitics, deal resistance, and analyst expectations can pull individual stocks in opposite directions.
