@Shakti Man Although I am no expert in this topic. But it mainly depends on your investing style. If you are short term investor, then you may set a particular price in mind and sell it in listing gains.
If you're long term investor, then you may consider holding the shares of the company for a really long time.
Whichever, suits your requirement can be adopted as your investment strategy. But in the end of the day, once you take a decision don't think about what if's.
