S&P 500 futures showed little movement on Tuesday, with semiconductor stocks continuing their downward trend from the previous day. This cautious trading environment comes as investors anticipate significant mega-cap tech earnings reports and the Federal Reserve's upcoming interest-rate decision.

Market participants are closely monitoring the performance of chipmakers, a sector that has recently experienced a notable downturn. The uncertainty surrounding these earnings and the Fed's monetary policy are contributing to the muted sentiment in the futures market.

Traders are balancing the potential impact of corporate results from major technology companies against the broader economic implications of the Federal Reserve's stance on interest rates. The coming days are expected to bring clarity and potentially influence market direction.
