You're awesome man. hahah I know about your feelings about timing Mr Epps_sg. I asked cause I have around 15k to invest and I wanted to go all for gold ( and invest in the rest when I have money) since I read earlier that 
>20k investment in a gold etf has lower yearly fees. 
Underlined statement should read as >20k investment in UOB gold savings account has lower yearly fees.
Am at UOBs website reading the rates on gold and also checking out the december post on your blog as i'm typing. On 2nd thoughts I might just put in 4k per asset as of now. Yup, I'll get my hands on the book asap. 
If 3~4k per asset is what you can do now, that is still fine. Use Gold ETF instead of UOB gold savings account. Craig Rowland has recently co-authored and released new book on Permanent Portfolio, which you can 'try' to borrow from National Library.
Want to share with you guys the gist of an article I just read on todays BT. The author, Cai Haoxiang mentioned 3 "Catches" for ETFs.
Catch 1. Most ETFs in Singapore are classified as Specified Investment Products (SIPs). That means you have to take an online test at sgx.com and achieve a score of 18/20 or have CFA/ ACCA accreditation. Apparently this is due to the ETFs being complex and more difficult for the average retail investor to understand. Does anyone know what the questions in the test are like?
Have a look here for more info. You can try till you pass. Test is free of charge.
Catch 2. Broadly, there are two types of ETFs. First are direct-application or cash based and the 2nd are synthethic ETFs. Around 1/6 of ETFs belong to the first category i.e owning shares in an ETF that tracks 10 stocks would mean that an investor would be owning a share in the ETFs portfolio of the 10 stocks. If ETF provider goes bankrupt, investor has recourse via the stocks held in the ETF. Examples of such ETFs include ST, SPDR DJIA. 
2nd group is called synthetic ETFs cause they do not own the assets they are meant to track. Rather they use derivatives, usually swap contracts, to mimic the movement of the basket of stocks they are tracking. Long story short, if the bank agreeing to do the swap goes bankrupt, investors might not be able to get back what they invested from even if the underlying stocks remain unchanged.
Always use cash based ETF to minimise such "counterparty risk".
Catch 3. ETFs can be illiquid due to low supply and demand. There can be delays that measure in days or even months if an investor wants to sell the ETF. If ETF is denominated in a foreign currency, there would be risk due to currency fluctuations.
STI ETF (ES3) and Gold ETF (O87) are relatively liquid. The 30 year Singapore Government Bond (PH1S) is relatively illiquid most times, but the primary dealers are required by MAS to always provide buy sell quote for the bonds on SGX. If in urgent case, may try call broker to help sell the bonds.
STI ETF and local bonds are in local currency, so no currency exposure. For purpose of this portfolio, do not hedge Gold ETF or gold product no matter which currency you use to buy the gold, so foreign currency exposure is not a concern here, unless you purposely bought into a foreign currency ETF or bond fund.
