All sound advice so far!
I'm assuming that your after tax income is $39k, and you are saving $19.5k? i.e. fortnightly you will be
I'm in Australia and use some of these investment vehicles. My savings rate is a bit higher (typically buying >$5k at a time), so for me it was a no-brainer to go for the listed versions. I'm also of the view that if you are holding investments for a long haul (and lets be honest, that's what we plan for index investments, right?), you want to try to drop those annual costs.
My current portfolio is about 40% direct stocks (16 individual ASX50 stocks), 10% direct (5 direct REITS), 10% US ETFs (IVV and VTS), 10% rest of world ETF (VEU) and 20% LICs (AFI, ARG, MLT, BKI, CIN). I have also had VAS, STW, IVE and IEM in there in the past.
My personal preferences and rationales:
Australian shares: I preferred VAS over STW, as it had a lower expense ratio, and was slightly broader (ASX300 vs ASX200). However, at the moment, I've preferred the LIC's, as they have been trading at a discount to the shares they own. This isn't always true though, at times they trade at a premium. I take the view that if the LIC's are trading at a discount, I'll buy them, If they are trading at a premium, I'll but the ETF (who's market makers keep it in line with the NTA). For a while I was buying individual large cap stocks, as I figured I'd rather keep the 0.15% MER of an ETF. However, the admin of dealing with that many individual holdings makes me think twice now. Furthermore, if you can buy the same portfolio at a discount (CIN for example currently costs $19.85 for a basket of shares worth $23.05, see
http://www.asx.com.au/documents/products/LIC_NTA_Report_November_2012.pdf for the monthly premium/discounts of LICs as published by the ASX), the market exposure of that extra 16% of shares more than makes up for the 0.12% management cost. Note that VAS includes some REITS (7% by weight), so if you want 20% exposure to REITS, then you can hold slightly more VAS and slightly les VAP (and pay 0.1% less MER on that portion).
International shares: I swapped from a mix of IVE and IEM to just holding VEU a while back. My rationale was that I could harvest a capital loss, and the expense ratio was lower. I've been wondering about direct international shares - partially because I don't understand what happens to the franking credits of the Australian shares within ETFs like VEU. It seems that these get lost?
All my personal opinion and not investment advice. All the best with whatever you choose to do!
