Stock Market Jitters: The Tale of Fed Rates, Oil Prices, and Tech Turmoil

U.S. stock indexes closed lower amid rising Treasury yields and concerns over Fed rate outlooks and Middle East tensions impacting oil prices. Investors anxiously await key earnings reports and economic indicators. Tech giants face scrutiny, as market volatility looms ahead of a possible hurricane impact.

On Monday, U.S. stock indexes fell sharply, adversely affected by elevated Treasury yields and looming economic uncertainties. As investors brace for the Federal Reserve's next move on interest rates, anxiety surrounding Middle East tensions and their impact on oil prices remains palpable.
