The S&P 500 (SPX) is back in positive territory for 2025. What's different about this bounceback is "the participation we've seen," says Kevin Green. He points to outperformance in industrials and financials indicating optimism. KG adds that getting to the 5950-5960 level is key and highlights "lighter" trading volume taking place right now. Later, Kevin looks further at the move higher in Nvidia (NVDA) as the A.I. chipmaker crosses above a $3 trillion market cap.
