Intel Corp. shares surged more than 10% in New York trading on Tuesday, lifting the stock to its highest intraday level in five months. Market-monitoring services put the gain at roughly 10.1% by early afternoon, and some quotes showed the advance briefly exceeding 11%. The jump followed a volatile stretch in which the chipmaker’s stock had dropped more than 3% during regular hours but reversed course in after-hours dealing, according to Benzinga. No specific company announcement was cited in the immediate rally, yet the size of the move put Intel among the day’s strongest performers in large-cap U.S. equities. Broader benchmarks showed little direction at the end of last week: the Dow Jones Industrial Average slipped 0.08%, the S&P 500 was essentially flat and the Nasdaq Composite edged up 0.03%.
