One input I want to give is that
Finding multibagger is not only sufficient. Allocating right amount of money and holding it (EQ and Psychology game) is also important. Which is not an easy task.
Secondly I have seen many people doing hope investments and end up buying worst category of stocks in the hope multibagger. Don’t do that!
At the end overall return on portfolio is more important what ever is the method
15-20% every year for 20 years is 15-38 times If you are able to do so then you are multibagger by your self.
All the best for your investing journey
