Dude - i'm no sifu ar.. thus clarifying with U:
Apa tu
a. RSV?
b. RSP?

I thought i was quite updated with the things one can do with EPF A/C1 & EPF A/C2 - looks like there are more options based on your posting, the hunger..... 

PRS izzit? Private Retirement Scheme?
OR
really RSP? Stands for what ar bro?

er.. yeah those are the initials 
Pardon moi - got used to the terms used in LYN - DDI (direct debit instructions AKA monthly standing instructions) thus doing Dollar Cost Averaging
OR every period execute manually value cost averaging or value investing.

Ok down to the heart of the matter - where U shd do it now or later right?
Opinions / Point of View follows (not rules yar)
Simple - 1st things 1st, have U built up at least an emergency buffer / kitty of 3 months' average expenses?
eg. Say U spend $12K pa all in all, thus your average expenses pm = $1K, thus U should if possible have $3K squirrelled off somewhere safe & stable - eg. savings a/c + FD
This $ is to save one's tail in case of emergencies (no, not when U NEED that new coach bag or S3) INSTEAD OF BEING FORCED TO SELL your investment to cover tail. When one is forced to sell, it may not be the right time and one can incur losses easily.
Why?
Simple - ALL investments (excluding FD, savings a/c lar - those are generally "storage") have some sort of transaction costs, either when buying or selling or BOTH. Unless one is incredibly lucky, usually it takes time to break even then make profits.

Then after building the above OR while working on the above, checkout what amount of risks U need to cover.
(Keep in mind, insurance is to cover and transfer your risks, NOT as investments.)
eg.
a. if U have economic dependants, pls ensure U have death insurance - yes, death insurance, not life as it pays out after death
Get enough and at the best bang for the buck.
b. does your employer cover enough hospitalization & medical? - no, then please look into it.
Again, insurance should be used as a risk transfer (to insurance Co) and to cover costs which will be disastrous to U or your loved ones.
Buy enough for now + maybe forseeable future (3 years? 5 years?) - balance your coverage needs with costs/affordability.

Now, when U have the above 2 settled - U should have a good hands-on on money & risk management, ie. spending less than U earn by living below your means, thus enabling U to build and accumulate wealth. In addition, WHILE doing the above, learn about asset allocation, classes of assets, investment methodologies like dollar cost averaging, value cost averaging, value investing, growth investing, trend, etc.

Then start accumulating your ammo for investments and while accumulating - formulate a big pix plan, perhaps based on asset allocation + execution methodology coupled with selected/filtered specific investments (eg. DCA with PFEPRF, VCA with PIX, value investing with stocks like PBANK, NESTLE, DLADY, etc.)

Track them and manage them as per your plans and methodologies.
By tracking them, U can then review monthly, yearly, etc. whether your picks AND methodologies work - else tweak.

Phew.. digest digest heheh. Hope the above summary helps.
