I'm paraphrasing pieces of Warren Buffet, Paul Merriman, and whitecoatinvestor.com in this reply, in case it sounds familiar:
1) You mean a 30 year old should have their age in bonds? Or no bonds at all? I've heard the debate about technically we should all be stocks and bonds are there check human psychology. I've heard Vanguard Retirement Funds became pretty aggressive recently.
Haven't heard about Vanguard and being aggressive, but I think someone who has a timeline > 20-25 years should be 100% stocks and 0% bonds. It's fine having the opinion that someone should be at least 10% bonds or more, but at least you're having the discussion and the investor has that assumption of risk.
The problem with target date funds is that the decision is made for you*, even though an investor may have a larger appetite and expectation for risk than is given. Of course, that person should then branch out and invest themselves, but there's a false sense of risk/expected return conveyed in a paternalistic manner with these funds. My feeling is, if I see "2050" on a fund, I would expect the most aggressive style of investing, but that's not always the case. Even iShares' "aggressive" core holding (AOA) is upwards of 20% bonds.**
Buffet's recent letter reminded shareholders that volatility is a false surrogate marker for risk, risk is the permanent loss of capital, and failure to overcome inflation is the true risk. Being too conservative is thus the greater risk and therefore why I think these target date funds unduly expose novice investors to risk.
*yes I get that's the point of a target date fund
**yes it's right there in the prospectus... yes people should read those
2) DFA...you mean Dimensional Fund Advisors? Would you recommend them over Vanguard index funds? Cause I'm a bit confused as to what DFA does exactly that's different than Vanguard and their performance. It's a lot easier to understand what Vanguard's philosophy is compared to DFA.
DFA...whitecoatinvestor has a page devoted to this, I have to agree with them that hiring an advisor for the sole purpose of accessing DFA funds (remember, you can't buy DFA funds as a retail investor directly) is probably not worth it.
I personally like DFA funds for their value tilt, and use them when available depending on which friends/family members' money I'm managing. Their small-cap value fund goes MUCH deeper into value than Vanguard's...but factor in advisory fees, higher ER, etc... it will likely end up being a wash in the end (but who knows). Paul Merriman has a few good podcasts and articles devoted to small-value/small-cap tilting and cites the DFA study I talked about earlier.
If you really want DFA funds without an advisor, Utah's 529 plan (UESP) has them available for use in that vehicle.
