Intel reported earnings of $0.52 per share on October 29, exceeding the analyst forecast of $0.41. Despite the positive report, the company's stock price dropped by nearly 29% the following day, marking its worst single-day performance since 1973.

The market decline resulted in a loss of over $100 billion in market capitalization for Intel in a single session. The company faces challenges including a decline in the PC processor market, which it expects to shrink by 12% in 2026 and 10% in 2027, alongside supply chain issues and a negative annual cash flow forecast.

Broader market indices showed more moderate reactions compared to the headlines. The Nasdaq-100 index retreated by approximately 10% from its October peak, while the S&P 500 saw a decline of only a few percentage points. Intel's stock remains valued higher than it was in January.
