Compulsive stock market investment is now a new disease included in the DSM and henceforth we must make people who are prone to develop such compulsions aware of the same that this is a problem and they need to stop before they burn themselves out.
Point is that either type of compulsive actions are destructive, be it in gambling or trading or shopping or eating etc. However this compulsion comes as a counter mechanism to another obsession. Truly this revenge trading is a problem if someone is doing it regularly. Trading must be done with patience and research, waiting for the low price, pouncing on that and waiting till the high is reached to sell. Only then it an organized execution yielding the maximum possible profit.
That is actually a very serious one, considering how easy it became to be a retail investor and you do not need some broker in wall street to do it for you, there are a lot of people who download apps on their phone and trade stocks there. This results with plenty of people who have absolutely no idea how they can trade, end up trying to make money from it.
There are some small few cases which it worked, retail investor vs big hedge funds in like Gamestop stock being pushed to limits. But usually that results with retail investors like you and me losing money. It is not "too" different in crypto neither, there are top guys who make money, and panic sellers who lose.
