Stocks are near record highs with the 10-year Treasury yield above 5%, and one source of profit explains it. AI is expected to supply roughly two-thirds of the S&P 500's 30% earnings growth this quarter, with semiconductor profits projected up 136%. That support comes with a higher bar, and the first real test lands Thursday when Taiwan Semiconductor reports.

AMD just crossed $1 trillion for the first time, but it didn't rally alone. Chip stocks surged, the Nasdaq set a record, and the AI trade may finally be broadening beyond Nvidia. Here's what's driving the move, and the test AMD faces next as it tries to hold the trillion-dollar line.

Broadcom more than tripled AI chip revenue to $16.7 billion and forecast roughly $230 billion by fiscal 2028 — and the stock still fell. Snowflake jumped more than 20%. HPE posted record revenue and dropped over 3%. Same sector, same tailwind, three different verdicts. Here's what the market is actually pricing now, and why the 10-year Treasury yield matters more to these stocks than the guidance did.

Nvidia reports Wednesday after the close with roughly $280 billion of market value in play — more than the individual market cap of 90% of S&P 500 companies. But the implied 5.4% move is smaller than Nvidia's recent average, and the stock just posted its seventh straight down day. The real variable isn't in the income statement. It's the 30-year Treasury yield sitting above 5% at a 19-year high, quietly repricing every data-center project the AI trade depends on.
