This daily chart of AMT shows a clean impulsive move higher with the stock currently trading sideways in a wave 4 triangle. Good alternation between waves 2 and 4 supports the bullish outlook. It's also worth noting that wave 3 was a perfect 161.8% Fibonacci extension of wave 1, which is a common ratio for an extended third wave. Initiating a long position at 141 with a profit target at 160. A move below 125 invalidates the setup.
