I posted an idea a while back (2017, February) positing a top for this stock that turned out to be correct-ish. However, I called that as a top of an extended 5th but now I'm not so sure and reckon that it may have in fact just been the end of a 3rd wave and what we have just witnessed is simply a deep 4th wave correction. If correct, it would suggest that there are still gains to be had in this stock and other US equities.
