You wait for the callback, touch the top, wait for the waterfall, wait for the wind and the rain, and as a result, the bull market has gone halfway. The bull market always starts in doubt and ends in enthusiasm. You regret why you didn't seize the bull market in the past few years; you were neither aggressive in going long nor were you thinking about shorting, just trying to make a little money. As a result, the bull market has passed, and you start to go long.
