U.S. Stock Futures Dip Amid Anticipation for Walmart Earnings & Fed Insights

U.S. stock index futures took a dip on Thursday as investors adopted a cautious stance ahead of earnings from retail giant Walmart and potential insights from a Federal Reserve conference in Jackson Hole.

Earlier in the week, technology stocks experienced a sharp downturn, sparking concerns of overvaluation following their rally from April lows. This, coupled with Washington's increasing involvement in the tech sector, has rattled investor confidence, according to experts at the Stock Trader's Almanac.

Attention is now focused on Walmart, with investors bracing for possibly muted optimism from the retailer in light of economic cooling. Meanwhile, traders are keeping a close watch for any signals from Fed Chair Jerome Powell that could indicate a shift in interest rate policies.
