Why do investors / active managers obsess over “the bottom”?

Serious question, if a stock is going to $100 in a reasonable time horizon, is it worth missing at $5 because you think it might go to $2?

Or missing at $5 because it was $2 just a few weeks ago?

Something to consider.

Energy spent trying to find a market or a stocks “bottom” might be better spent trying to find the next wonderful investment idea (or spent on Twitter, which is how I spend my time)
