Charles Schwab's Kevin Horner sees the S&P 500 (SPX) pushing toward new highs, with 7,820 as the key level to clear before targeting 7,890 and 8,000. He highlights KLA Corp (KLAC) as a semiconductor name finding support at its 200-day moving average with a potential rebound to 192. Horner also likes Nvidia (NVDA), which has broken its downtrend, consolidated, and is now challenging 235 as it nears record highs.
