US stock indexes swing as Broadcom results trigger chip‑sector sell‑off

The Dow Jones Industrial Average reached a record high of 51,549.34 points, buoyed by gains in health‑care and financial stocks, while the Nasdaq Composite slipped modestly to 26,802.76 points after Broadcom reported earnings that fell short of analysts' expectations.

In a separate session, the Nasdaq suffered its biggest daily decline in 14 months, falling about 4% to 25,709.43 points, and the Dow dropped 1.35% to 50,866.78 points. The tumble was driven by a sharp sell‑off in semiconductor shares, with Broadcom and other chip makers such as Marvell, Intel, AMD and Micron posting steep losses. The iShares Semiconductor ETF also fell 10%, underscoring the breadth of the downturn.
