Stock trading after a crash
There are two things going on here, neither of which favors this approach. First, as @JohnFx noted, you should be wary of the sunk-cost fallacy, or throwing good money after bad. You already lost the money you lost, and there's no point in trying to "win it back" as opposed to just investing the money you still have as wisely as possible, forgetting your former fortune. Furthermore, the specific strategy you suggest is not a good one. The problem is that you're assuming that, whenever the stock hits $2, it will eventually rebound to $3. While that may often happen, it's far from guaranteed. More specifically, assuming the efficient market hypothesis applies (which it almost certainly does), there are theorems that say you can't increase your expected earning with a strategy like the one you propose: the apparent stability of the steady stream of income is offset by the chance that you lose out if the stock does something you didn't anticipate.
