Markets Slide as Tech Earnings Disappoint and Oil Prices Spike

The sell-off in the S&P 500's communication services sector was triggered by lackluster second-quarter reports from Alphabet and Tesla. Investors, previously buoyed by aggressive capital expenditure in AI, are now questioning the immediate profitability of these massive infrastructure investments. This skepticism has effectively erased recent gains, leaving traders to re-evaluate the risk profiles of the industry's largest players.

Adding to the volatility, the brewing conflict in the Middle East pushed crude oil prices toward $100 a barrel. This surge threatens to reignite inflation, complicating the Federal Reserve's path forward as officials prepare for their upcoming policy meeting. The prospect of sustained high energy costs forces a shift in interest rate expectations, creating a difficult environment for equity valuations that depend on a stable economic outlook.
