At the same time, it's holding 3.9% above its 50-day SMA ($62.91), which is the nearer-term line bulls want to keep intact.The tug-of-war shows up in the moving-average structure: the 20-day SMA is above the 50-day SMA (a bullish tilt), but the 50-day SMA remains below the 200-day SMA (the death cross that printed in February), which keeps the bigger-picture trend cautious. With shares now 4.1% below the 20-day SMA ($68.15) and 4% below the 100-day SMA ($68.07), rebounds may run into overhead supply quickly.
