Just starting out.

Hi guys. Im a 19 year old guy trying to learn about the stock market. Im approaching this industry wise and I am currently researching the FMCG industry. I would love to hear about your personal investment experiences regarding FMCG's and I have a question too. Do you think this is a good time to invest in FMCG's to yield a return of 100% to 200% in 3 years? This is for a thesis im writing. Any help would be appreciated. Thank you.
