Stocks fell sharply as hot inflation revived rate fears and tech led the decline.
The day closed lower, with technology and health care lagging while energy and utilities led, because hot inflation data pushed borrowers' costs higher and sent investors toward safety. The tension is real: the long-term story of building out artificial intelligence remains intact, with strong demand for chipmaking equipment, yet the market's leading chip stocks broke down hard anyway, and fear rose even though the broader trend still reads constructive. Expect the next session to hinge on whether nervous credit and jumpy volatility spread into the average stock, or whether the calm breadth and intact trend hold.
Why it mattered: Today sets up a test of whether the selloff stays confined to the crowded winners or broadens into the whole market.
What we said to watch
Watch whether riskier company debt keeps selling off when the market reopens, since that nervousness resolving or spreading will tell the story.
This is the reading as it was written on the day. It has not been edited with hindsight, and it may have turned out to be wrong.
