Intel Fell 28.6% in Its Worst Day Since 1974

Intel shares fell $26.31, or 28.6%, to $65.76 on 30 Oct 2026, from $92.07, their worst session since 5 Jul 1974 by Yahoo Finance calculations from Norgate Data going back to May 1973, topping the ~26% drop of 2 Aug 2024. The trigger was Q4 guidance: revenue of $15B–$16B and adjusted EPS of 25¢, against about $17.1B and 43¢ expected (LSEG), with the CFO seeing the PC slowdown lasting at least through the first half of next year. CNBC estimates the US government's 10% stake lost about $12B in value and Nvidia's stake about $6B. The stock is still up nearly 80% in 2026.
