[Concerns Rise Over AI Investment Returns; Nasdaq 100 Faces Third Technical Correction This Year] On October 31st, the Nasdaq 100 index fell as much as 4.5% intraday on Friday, dropping more than 10% from its recent high, facing its third technical correction this year. The index has fallen approximately 3% this week, with disappointing earnings reports from Alphabet (GOOG.O), Amazon (AMZN.O), Intel (INTC.O), and ServiceNow triggering a sell-off in tech stocks. The market is beginning to reassess the return on AI investments, and increased funding needs from tech companies have exacerbated sector volatility. Market strategists point out that investors no longer assume AI investments will necessarily yield high returns, but are instead focusing on return on capital and whether the initial investment can be recovered. The last time the US stock market experienced three or more 10% swings within a year was in 2022.
