Wait for the dust to settle with US politics post inauguration. Bubble popping may not happen until then. Past bubbles took about 1+ to 3 years from the start of the bubble forming.
APT realistically only started going nuts in valuation (past upside target price of ~$28-$30 of reasonable valuation metrics) around May. So the Bubble may last for quite some time riding on the new president euphoria and vaccines and opening of borders etc.
BUT!.... it can also happen on Monday if a few majors start selling to balance a skew heavy portfolio in a fund, so unpredictable.
