Decisions about investing should be made through your own research, not based on advice from anyone. Moreover, if you have taken the right first steps by studying it first before deciding to buy, then when you want to sell it, you must also base it on your own research so that there will be no regrets. Usually investors will set a target, for example how long they will keep it or at what price they will sell it and sticking to the target that was initially set is a good thing in investing.
