I think a small portion of your portfolio in the local market is fine. I bought PPE at 27c a few months ago and now it's at 90c. Decent growth. It's a bit of an outlier for me though, I have some terrible picks.
I know there is way more to analysts picking stocks based on things way above my head and succeeding, but I mean, monkeys can do it too, without all the fancy algorithms- so I take these sorts of articles with a pinch of salt.
