US stock indices bounce on technical support amid earnings season uncertainty.

US stock indices including the Nasdaq 100, Dow Jones 30, and S&P 500 showed resilience on Tuesday by bouncing off key technical support levels. The Nasdaq 100 held above 28,500 after rejecting the 30,000 resistance level, while the Dow Jones remained in a strong uptrend above 52,000. The S&P 500 tested its ascending triangle trendline and held above the 50-day EMA, suggesting a potential buildup for a future rally. Earnings season and global interest rate concerns continue to influence market movements, with investors watching key technical levels closely for direction.
