i dont believe this bubble last without 2 things 1: stimulus, which get voted on friday december 18th & 2: fomc meeting tmrw, is the fed going to continue to to stay cautious or tighten up.. retail sales are expected to decline, covid is rising again , and im interested to see how the fed reacts... remember the second stimulus was already priced in, but have YET to see it.
also in the long term a stronger euro impedes and slows down the European recovery. Their currency strength doesnt match up with their economy, this may be the end of the bubble, respectively
