IBM shares drop by more than 25% in early trading in New York, according to reports. The decline is large enough that the drop could exceed IBM’s previous worst one-day fall and would top the record 23% one-day decline reported for Black Monday in 1987, the outlets note. The selloff is described as occurring amid ongoing challenges for the company as the broader technology sector continues to focus on artificial intelligence. One report estimates the market value loss at around £50 billion, reflecting the scale of the share decline. The coverage presents the move as the steepest one-day drop in IBM’s stock history, or potentially beyond historical benchmarks if the decline persists through the full trading session. The reports do not provide further detail on the specific company events driving the move, focusing instead on the magnitude of the share-price fall and its comparison with major market declines in prior decades.
