William Bernstein Discusses Tilting Hey, rjb.
I get where you're coming from, but Bernstein was attempting to write a popular statistical model of a portfolio that would approach the Efficient Frontier, while claiming that, since you can't know future asset class performance, you can't know where the Efficient Frontier will lie. In order to do that, he looked at historical asset class performance and correlation. For foreign, since he's writing in the late 90s, the only thing he has long term data for is the EAFE. For small he uses the CRSP 9-10, which gets much farther into microcap territory than VTSMX.
When he starts talking about asset allocation in Chapter 5, he admits up front he is "an asset class junkie," and is willing to own "20 or 30" different asset classes. But the rub is that he wants everything to be a separate asset class. We have 15 years of hindsight and recency bias showing an across the board increase in correlations. For instance, Bernstein approaches bonds as a risk control tool, and assumes correlations of .777 between SC and the S&P 500, and .483 between the EAFE and the S&P 500. It's not so much that Bernstein doesn't want to use total market indices, but that doing so doesn't allow him to really make his broader point re: diversification because there is a lack of data. He ends up using the European stocks as a proxy for the EAFE because there wasn't a Vanguard DM fund yet.
The portfolio Ted points to, he calls the "Level-One Asset Palette," and he designs it for those who find "reading this book ... the equivalent of root canal work." Quickly after he presented it as his Lazy Portfolio. In the book he presents second level and third level "palettes," which include EM, Foreign smallcap, REITs, Natural Resource stocks, short term bonds, TIPS, foreign bonds, and valuation factors.
Not sure if that helps or not, but that's what I gather his reasoning is. Personally, if you're going for as much growth and diversification across 4 asset classes as you could easily get, I would think something like CRSP 9-10 (VB or VBR), foreign small (VSS), Real Assets (VNQ, RWO, VDE, or ALPS), and either an intermediate or hedged foreign bond fund (BND or BNDX) would be better. But some of those funds didn't exist 15 years ago.

@Catch22,
Calling LT treasuries "equity insurance" might have sent this discussion down the wrong path. Maybe a better analogy would be a portfolio shock absorber. LT Treasuries often out perform at times when equities underperform. Personally, an equity investor should expect a certain range of volatility. Bonds can help dampen and absorb some of the bigger equity bumps allowing an investor to stay "fully" invested.
Retirees recently have had to navigate through two market meltdown (catch22's term) over the last 15
years. If an investor held a portfolio consisting mainly of equities he/she would have two very large holes to fill.
To drive this point home visually I created a graph using a backtested portfolio tool which shows the impact these two meltdowns had on a 100% equity portfolio (ron's $500,000) verses two other portfolios that incorporated a mix of LT bonds and equities.

new frontier for MLPs JohnN,
You said something about tsp.....Thrift Savings Plan? Are you a government employee? Reason I ask is that my wife works for the gov't and has been investing in their TSP for years. Thanx in advance.

RiverPark Strategic Income: Portfolio Statistics David Sherman and his Cohanzick Team write in their 2nd quarter 2014 commentary that its funds are managed "very conservatively against most fixed-income risk categories."
However, he goes on to write "...a substantial percentage of the holdings in both funds are invested in below investment grade securities. Therefore, arguably the funds have above average credit risk. Our strategy to maneuver in current markets is founded in the belief that by staying small and nimble that we can take advantage of special situations where our perception of credit risk is different than the market or ratings agencies."
Once it gets three years under its belt, I would imagine RSIVX/RSIIX will have excellent standard deviation/return, Sharpe and Sortino ratings.
The only gripe - and it's a big one - is its expense ratio.
Managed Accounts: Too Pricey For Retirees I consider myself a decent investor but note that most years I underperform the appropriate target date fund though as compensation my risk is somewhat lower as I use a stable income fund paying 2% rather than a bond fund and I suppose I have more fun..Given the wide availability of target funds it is unlikely a managed account (1% OR MORE EXTRA FEE) is unlikely to be a good purchase
