I have just opened a SRS account with DBS. Please share tips to invest SRS money while avoiding high fees/ expenses via DBS?

The srs account with dbs give you a limited number of stocks or etfs to invest in, take your time and study these stocks before you invest

Use SRS to invest in shares. Their expenses are relatively not as high as other channels. On what shares to invest, SRS is more liberal than CPFIS which is good, there are some good shares you can invest SRS via such as Nanofilm. If you are looking for high dividends with moderate risks, maybe consider the US office REIT space (but avoid Manulife)
