Look around.
If there is any product that you buy and really love, check if they are on the stock market.
Read as much about them as you can online (call reports, financial statement, annual report).
If you believe in the management and align with the product offering. Go for it.
2 companies I bought that have given me >50x return in a few years:
- BLS International (booked visa via them for Spain)
- RattanIndia Ent (I ordered books from Amazon and cocoblu was the seller 90% of the time. Checked the parent company, they are into EV, drone etc)
P.S. - To maximise the gains, invest decent amount like atleast 1L lower than that the absolute returns will be too minimal to enjoy.
At max you will lose 1L but you may gain 50L.
