Kevin Horner returns for Technical Tuesday, breaking down the charts of the SPX, AAPL, and CART. He sees the 20-day SMA as support for the SPX as it continues to climb and expects the bullish trend to continue. For Apple, he highlights the breakout above $225 and thinks traders are digesting the jump. On Instacart, he shows the recent intersection with the 20-day SMA and a potential bear flag.
