It's not BRICS as a whole, it's China and a little bit of India.

Brazil is a major risk given political turmoil and generalised corruption; Bolsonaro attempted a coup in a country already plagued in history by coups, his son is going to run for presidency and has a chance to win it.

South Africa's economy is in shambles, their electricity grid can barely function, the country is going backwards socially and economically.

Russia I don't think we even need to talk about.

That leaves China and India, China has capital controls and is notoriously difficult to invest in.

I don't think there's much in common with BRICS as it was in the early 2000s when the acronym surfaced, as of now they are very dissimilar societies and economies.
