Chip Stocks Lead the Charge

Alphabet announced an $80 billion capital raise, including a $10 billion investment from Berkshire Hathaway, to fund artificial intelligence development. The company plans to spend as much as $190 billion on equipment and investments this year. Alphabet shares fell 4% on the announcement, as investors weighed the massive capital commitment against the company’s AI ambitions.
Valuation Concerns Mount at Record Highs
The Shiller P/E ratio sits at 42.78, its second-highest point since topping out at 44.19 in 1999 before the dot-com crash. Some analysts warned that current valuations mirror pre-crash conditions seen in 1929, 2000, and 2008. The S&P 500 posted 29 new 52-week highs and 17 new lows, signaling mixed breadth beneath the index’s record close.
