Warren Buffett's Berkshire Hathaway, famous for sitting on a giant cash pile, just disclosed it bought more Delta Air Lines and Alphabet stock last quarter under new chief Greg Abel. The same evening of big investment filings, Nvidia revealed a $21 billion stake in SpaceX — the biggest players in investing are clearly putting money to work in stocks again.

## Idea

Berkshire's huge cash hoard has long been read as a signal that its leaders thought stocks were too expensive, so new chief Greg Abel adding to Delta and Alphabet tells the market he sees value at today's prices. Stocks that Berkshire newly discloses tend to attract a wave of copycat buying in the days after the filing, because ordinary investors trust the track record. Alphabet offers a way into the AI boom at a much lower price than the market's favorite names, while Delta is a travel bet that has largely missed the tech rally, so both have room to catch up. The same evening of disclosures showed Nvidia parking $21 billion in SpaceX, underlining that the giants of investing are committing real capital — and the simplest way for a regular investor to ride that is the pair Berkshire just bought.
