  • US Stocks Eye July Jobs Data Amid AI Tech Sell-Off
    June 28, 2026, 1:42 PM EDT. US stocks shifted away from AI tech as the S&P 500 dropped 2.05% last week and the Nasdaq fell 4.7%, with semiconductor stocks hit hardest, falling 7.9%. Despite this, equal-weight indexes and smaller caps like the S&P 600 outperformed, rising over 1.5% and 3% respectively. Market attention turns to the crucial June jobs report due July 2, which could influence Federal Reserve rate decisions. Investors pulled $3.53 billion from US equity funds last week, led by nearly $20 billion outflows in tech funds. Experts warn a strong jobs report may pressure stocks, particularly tech and small caps, as the Fed balances inflation risks ahead of the July 4 holiday trading closure.
