Kevin Horner’s Technical Tuesday covers the S&P 500 (SPX), Amazon (AMZN), and Amgen (AMGN). On the SPX, he looks at support and resistance levels, and warns that if it breaks down, it could move fast. Amazon is “by no means in a bullish pattern,” but he marks the location of its pullback, calling the $198 level “very interesting.” Amgen is looking to break out of a bull flag, with consolidation over the past week or so.
