The bull market has never left us since May. It can not come back if it has always been there since April 2020.
This.
I think a good way to express it would be to ask if we have already left the sideways we were in. A bull market is not a straight line up, it has dips and periods of sideways. I think the answer is that we are out of the sideways because we have clearly broken the 50 day moving average mark.
