Benzinga examined the prospects for many investors’ favorite stocks over the last week — here’s a look at some of our top stories.

U.S. stocks endured a volatile week as investors reassessed the sustainability of the artificial intelligence boom amid mounting concerns over soaring capital expenditures by the industry’s biggest players. The Nasdaq Composite posted its sharpest weekly decline in months, weighed down by weakness in mega-cap technology stocks, while the S&P 500 also finished lower. The Dow Jones Industrial Average proved more resilient, supported by gains in industrials and financials even as investors grew more cautious about richly valued AI leaders.

Corporate earnings painted a mixed picture for the technology sector. Microsoft (NASDAQ:MSFT) came under pressure as investors questioned whether accelerating AI infrastructure spending would translate into sufficient long-term returns, fueling a broader reassessment of hyperscalers’ capital expenditure plans. In contrast, Micron Technology (NASDAQ:MU) surged after delivering stronger-than-expected earnings and upbeat guidance, reinforcing confidence in demand for AI memory chips and lifting semiconductor stocks despite the broader tech selloff.
