Deputy Prime Minister Tharman Shanmugaratnam said that more than 80 per cent of members who invested via the Central Provident Fund Investment Scheme (CPFIS) would have been better off leaving their money in the Ordinary Account, which earns a guaranteed 2.5 per cent each year ("CPF Investment Scheme to be reviewed"; Wednesday).

Perhaps the CPF Board should study the other 20 per cent of the CPFIS investors who do a lot better with their investments.

It could look at what they invest in (direct stock market investment, or unit trust, or others), how they invest (focus strategy or diversification, buy and hold or frequent trading), and when they invest (including their holding period).

Once the study is done, the information can be compiled into an investment guide or a course for new investors.

Right now, many CPF members rely on the recommendations of financial planners, friends and colleagues, or online resources that may not be very reliable.

The investing patterns of successful CPFIS investors can serve as a valuable guide.

These successful investors may also be able to provide valuable and practical suggestions on changes to the CPFIS.
