Charles Schwab's Kevin Horner sees the S&P 500 (SPX) pulling back from resistance with key support at 7,685 to 7,700, the 50 day moving average at 7,630, and last week's FOMC low near 7,500. He highlights Zebra Technologies (ZBRA) breaking out of a bull flag with a target near 415 while the broader tech sector struggles. Horner also flags ConocoPhillips (COP) pulling back to its 50 day moving average as a potential entry point for bullish energy traders.
