Temasek's 1-year shareholder return turns negative, more uncertainty ahead with Covid-19. What does this tell us about Temasek's ability to withstand the pandemic? Should investors be concerned?

I'm not too concerned. It's just one year of negative return. I'm sure they have seen worse. It's part and parcel of the market volatility.

Individual investors will have no relation to Temasek’s performance.

Temasek has to prop up Singapore’s economy.
It better be able to withstand anything.
