I can relate with this!
I am doing a course in Stock Market. I have come across these things and have even applied it to trading and I have fetched good and useful returns. Adding on to this, I would also like to share something about the industry and company analysis. We should always select that company which gives a positive report in it’s financial statements. For this we analyse a company’s Cash Flow Position, Balance Sheet, Income Statement etc.
Selecting a company who’s financial health is not so good, will lead to poor results.

I hope this helps!
Thanks!
