Yeah Gremlin is on point.
I normally consider costs based on a portfolio of 1M, so in that regard the 2bps of the ETF vs managed fund is $200/yr.
If there was some sort of benefit, I would consider that a fair price, but for the long term investor with multiple decades ahead and low one-off brokerage cost, the benefit of more frequent transactions doesn't seem to have almost any value.
The other option is a DIY version. If you leave out bonds (most appear to prefer to do their bonds themselves), it would be basically
VAS 40%
VGS 33%
VGAD 15%
VGE 6%
VISM 6%
This will have an MER of around 0.20, and for a $1M portfolio, that is 2k every year vs 3k every year. Not insignificant IMO.
The upsides
• More tax efficient in drawdown as you sell only the winners
• Cheaper (1k every year is nothing to scoff at!)
• You can adjust the weights. I would make VAS 20-30% Max and adjust VGAD based on my total assets (property, bonds, shares) such that total AUD ratio meets my target of 50-75%
The downsides
• You can adjust the weights. You may respond to market noise and end up selling based on information that turns out to be rubbish as most of it is, whereas having an all-in-one, you can't screw it up, and screwing it up is the most costly part of investing, showing a long term loss of much more money than the 0.7% MER that you will save over VDHG.
• Have to rebalance yourself (not a big deal)
If you do split it up
• There is a lot of ambiguous research showing whether small caps out performs on a risk adjusted basis, plus it has a higher correlation with the rest of the market anyway, so I think it's reasonable to fold VISM and VGE into a single 10% VGE slice, giving you a fairly simple 4 fund portfolio.
Beware the downside I mentioned, nobody thinks they will mess it up and change allocations based on everyone saying the Australian market is good or bad, or that they will stop rebalancing into the laggard, but it is human nature to do so. For many, this alone will make it better to go with the all-in-one even at the slightly higher fee.
