With all that has been happening with financial markets, market caps of many stocks are significantly different from what they were at the start of the year. This has prompted thoughts that there could be changes to the constituents of the Straits Times Index (STI) when the next quarterly review comes along. The STI is made up of the top 30 largest and most liquid stocks on the SGX; the top 10 constituent stocks make up ~70% of the total index with Banks being the biggest sector at 40%. As of the Mar20 review, there were no changes to STI constituent stocks. The next review is in Jun20 where I think there is the potential for Mapletree Industrial Trust to be included and SPH to be deleted (more analysis on this below).
