ReAttempt, Thanks for your inquiry --
Yes I am becoming more and more a fan of ETFs for long term investors -- main reasons not always cited are tax efficiency (no cap gains taxes being thrown off every year by the selling a mutual fund does for redemptions) and second, no penalty for being in the same boat with dummies (when fellow fund-holders panic and sell into disastrous markets, your mutual fund shares take an extra and permanent beating because your fund manager has to sell the collective assets at firesale prices to meet redemptions, leaving the remaining shareholders with less than they would have had in an ETF. In the ETF, redemptions are just shares sold on the exchanges --taking the fund perhaps to a discount-- but you'd still have the same number of underlying assets in your ETF share. If a market maker wants to permanently redeem shares, take it out of circulation, they literally hand over the ETF shares and receive the component securities, again, leaving remaining ETF shareholders intact.
Obviously ETFs are a tool with risks - (overtrading, buying too-fragmented or too-narrow sector funds, buying actively managed ETFs, and some sense that bond ETFs may not be a great idea) but that need not concern the stalwart long-term investor looking to replace equity index mutual funds.
To the question of replacing DFA funds -- yes there are some good new options out there. At this point I think there is a good fund or ETF replacement for just about every DFA Fund in the Work Less Live More Rational Investing Portfolio:
PFUIX for global fixed income,
DLS for International Small Value, DISVX
VWO for general Emerging Mkts, DFEMX
VSS for International Small,
and a new one, EMGX which I don't own, for DFEVX.
The only thing I can see missing now is Emerging Markets Small (DEMSX) but while a lovely fund it is a tiny part of the overall mix, and stick around and there might just be something there soon, too.
This is a good development because holding DFA funds requires having an advisory relationship with a firm that DFA has blessed, and that involves complexity and an additional fee: not good things in our world.
Hope this helps. The sculpture is going great and the portfolio is holding up. Lets just hope the global profligate (Greeks, US Treasury, Portugese, fill-in-your-favorite deadbeat here) don't take us all down this summer...
