Abstract

Singapore's mandatory national defined contribution pension system permits participants to invest their retirement savings in a wide range of investment instruments if they wish, rather than leaving their savings in CPF accounts to earn interest rate by default. This paper asks whether workers seeking to earn higher returns can expect to do better than the CPF-managed default, by moving their money into professionally-managed unit trusts. We use historical data to investigate whether fund managers possess superior stock-picking and market-timing skills, as well as whether they exhibit persistence in performance and offer diversification benefits to participants. The evidence is mixed, which could explain why so few participants opt out of the CPF-run default fund.
