November 2 – Global artificial intelligence-related stocks experienced a broad selloff, with foreign investors withdrawing from Taiwan's stock market at an unprecedented scale in October, pushing the Taiwan Weighted Index dangerously close to technical correction territory. Data shows that overseas investors net sold $31.78 billion worth of Taiwan stocks last month, surpassing the previous record set in March this year. The massive foreign capital exodus underscores growing cracks in the global AI trading boom, as investors grapple with mounting headwinds including rising borrowing costs, surging AI expenditures, and disappointing corporate earnings. The Nasdaq 100 Index plunged 3.5% on Friday — its steepest single-day decline since June — while the Philadelphia Semiconductor Index plummeted 7.2%. Taiwan's stock market, heavily dominated by semiconductor shares, now faces the risk of further downside.
