Charles Schwab's Kevin Horner says the SPX's 20-day SMA can "very well" provide continued support for the index with "few and far between" breaks since April lows. In stock movers, Kevin points out a support range in Celsius (CELH) by widening the view in an 18-month chart. He later talks about the "intriguing" move in Lyft Inc. (LYFT) that opened the door for bulls.
