My investor makes a net 10% return over half year of investment in PEF.

yes, I am an agent. Which funds have you invested in?

How long have you invested in those funds?

Based on here for a half year investment, Pbgf is getting a total return of 6.15%, which means you are starting to make a net return of 0.65% (6.15%-5.5%). However, things look bleak for Pbindobf as from the chart, it is still making -0.44% return, and this translates to a -5.94% return from your investment. For Pbcaef, it looks just slighty better with 2.42% gross return.

I can give you some advice, but in the end it still depends on what's your risk appetite, how long you are willing to invest, and your preference over investment portfolio (local or overseas funds). For your situation, the reason you choose both China and Indonesia fund is because you are interested in these two overseas market, am I right? If that's the case, then you have 2 choices: first, to continue your investment in these funds if you believe overseas markets will have a strong growth in the coming years, or switch over to other lower risk investment, such as local funds.

For me, I will usually advise my investors to go for funds with good track records (such as PEF, PDSF, PFSF, PITTIKAL, etc).

Yes I do invest in PFETIF for about 1.2 years but unfortunately need to sell it off because urgently need $$.

Anyway I do make net profit of 33%.

It's actually depends on what you think of those market, and this is quite subjective due to the fact that China and Indonesia are new funds which none of us can do too much analysis about it. A good previous example is that during the beginning of Public Mutual's award-winning "Public Smallcap Fund": on the first 18 months of the fund, the performance is not good, with approximately -4% return for the investors, but guess what? Investors start making money thereafter, and reap hefty profits from the investment.

As for myself, I have invested a small amount in China market, previously losing money but recently the fund start to make some return. The fact is that I'm also facing a similar dilemma just like you, wondering whether I should continue investing in the fund. 

Only invested 6 months then considering to switch? i think is too fast...u cant even to recover ur 5.50% service charges...
UT is for long term, anyway u can make it for short term investment (i think many people invest in UT like invest in share market), but the result might be disappointed...
unless u enter in end of 08 or beginning of 09...then the return is nice...
