I got my Ellie's in 2 trades at an average R5.23 including costs and PNC at R15.76 also in two trades.
If I thought they had a crap future, I wouldn't buy them.
PSG is more for Capitec, and some Curro.
The brokers were saying that PSG was expensive when I bought at R65, but I bought anyway as I wanted a slice.
If you want to do research then try places like sharechat, and moneyweb.
You can also learn a lot from browsing the actual companies website, and reading their annual reports.
Also a few investing books you can read...
My favourite would be the ones by Mary Buffet.
You can learn how Warren Buffet values shares etc, it probably won't help you replicate his success though.
I wouldn't pay for research.
I do read broker research at work which we get for free. It is useful for seeing how professionals value a business and saves you from doing some calculations.
I generally don't follow their advice.
Brokers tend to make their money out of making people trade and not by following their own advice.
They don't mind what you trade, as long as you trade, so they'll happily churn out research which will encourage you to do that.
