Singapore Shipping Trust. by Goh, Wei Qin., Lee, Suat Cheng., Tan, Li Ping.

“…We also explore the shipping trusts’ financial performance through comparison with the Singapore market, as well as with Singapore REITs, Singapore shipping stocks and their foreign peers. Results from CAPM show presence of risk-adjusted returns for the equal-weighted shipping trust portfolio in the before-subprime period, indicating the attractiveness of shipping trusts during better economic conditions. …”
