I normally refer to The Edge (which is weekly) or Personal Money (which is monthly) for Unit Trusts Performance. Personal Money has a page on Stock market indicators, FD rates and Unit Trust Performances.

Also, you may need to know the year end of the Unit Trust you are purchasing. It will be cheaper after the dividend payout. So if you are going near that date you may want to consider waiting a bit longer.

For the Gold Investment, the prices are different if you purchase Gold Savers Passbook or Kijang Emas, or other forms of Gold. Two banks offering the Gold Passbook are Maybank and Public Bank. I'd prefer Public's rates, but I will let you all decide. You can do the research online.
