US equity markets decline as Alphabet and Tesla shares drop following earnings reports

European equities are declining amid investor concerns over energy-driven inflation and the European Central Bank's (ECB) decision to maintain interest rates. This follows a significant sell-off in US tech stocks, particularly Tesla and Alphabet, driven by a shift in investor sentiment towards immediate cash flow over long-term AI capital expenditure. The market reaction reflects uncertainty regarding central bank responses to rising oil prices and the potential for sustained high interest rates.
