I think the typical TSMer views diversification as stocks/bonds and US/Int. This book views diversification as across unique and independent sources of risk and expected return. Has it compelled some of us to look at diversification differently in the low expected return environment?

Regarding International (sub) performance, perhaps someone can help me figure this math problem out: From April 30, 2007 (the date I started investing in a taxable account) to February 17, 2023 (the date I last checked), Vanguard Total Stock Market (VTSAX) gained 275.90% while Vanguard FTSE Ex-US (VFWAX) gained 51.44%. (Figures are from Morningstar data). And if I am reading the Morningstar chart correctly, $10,000, invested on April 30, 2007, would now be worth worth $37,590.26 if invested in VTSAX, and $15,099.25 if invested in VFWAX. That’s quite a difference in returns. But here is my first question: Assuming that VTSAX stays stagnant (ie, returns 0% going forward and the value of one’s holding in it stays at $37,590.26), how much woul...

Their suggestion is to invest more in International to increase dividend yield because the US market...

But I do think they are rules based and have no individual security selection or market timing. Help me understand something please. Yes, quant funds have algorithms and rules-based processes that allow them to trade to a consistent strategy, but those human-built algorithms still produce buys and sells of individual securities, don’t they? I don’t see how the “human or algorithm” question relates to the “passive or active” question. It seems like the quant guys still are picking individual stocks as opposed to buying the whole basket. Not true? My understanding is that they are buying stocks according to specific characteristics, but if two stocks are identical by their metrics, they are indifferent to which one they buy. Dave

It's possible to see a legitimate grey area around the word "passive." Traditionally, people describing DFA's "classic" funds like the DFA US Micro Cap Portfolio and the DFA US Small Cap Value Portfolio--I think DFA itself although I haven't been able to track it down--describe them as "passive funds, though not index funds." DFA is often thought of as a champion of "passive" investing, and a rival to Vanguard. And I am saying that according to the prospectus for this fund, it is Just Plain Active. There's no suggestion of it being rules-based, and the prospectus specifically says in so many words that it is actively managed. A Just Plain Active fund from DFA seems like a change in direction, althoug...

Another way to think about it: passive seeks beta (the cap weighted return of the market). Any investment strategy that seeks alpha is an active strategy. You and I are basically on the same page I think. I would say though that there is a beta for the market factor, beta for size, beta for value, etc. Past sources of alpha, once discovered, get turned into a beta. And it’s because these funds effectively access these other betas in an agnostic formulaic fashion that I think one can consider them passive. That’s why I say the funds are sort of their own indexes: you get what the factor loadings give you . It comes down to following construction rules. Larry Swedroe’s book The Incredible Shrinking Alpha details the phenomenon of converting ...

I hope we can agree that this DFA product is not "passive?" I agree (even tho there is no agreed definition of “passive”). What do you mean by that?

There are SEC marketing rules around this. All index funds are passive, but not all passive funds are index funds. Dave Can you give me a example? Yes. The DFA equity funds I would consider passive.

Recently read an Asness essay where he adamantly states that strategies such as this are active. Nonetheless I like viewing these formulaic methods as passive. The strategies have no individual stock picking or market timing, are rules based, and replicable.

So is the variance drain larger as distributions deviate more from normal? Does the equation perhaps underestimate the benefits of diversification for investors? Thanks,

I think a reasonable summary of a lot in the two curves above is as follows. In equity heavy portfolios, the portfolio risk is so dominated by the equity allocation that may as well take on the duration risk and associated premium of longer bonds. The increased risk on the bond side does not appreciably affect the overall portfolio risk but can add a bit to return. In much less aggressive portfolios with substantially lower equity allocations, it is more efficient to limit term risk to intermediate. I believe Larry Swedroe may have written on this.

Where a quant could help is to crunch the numbers and crank the formulas to get an idea of the right amount of diversification. In other words, how many asset classes do you need?

That being said, to intelligently determine our asset allocations, we need to think about expected returns, expected volatilities, and how different potential portfolio components mix in a portfolio. Looking forward, our expected return of an asset is an Ari Mean.

Expected volatility is not a property of a probability distribution. It is imperative to define such a concept before using it. And expected return is not the annual arithmetic mean of a long-term return.

So if you were to generate inputs for a Monte Carlo simulation what would you use?

Very, very few ordinary investors set up Markowitz’ formula in a spreadsheet, and run sensitivity analyses against it, as I’ve done for this thread (after 30 years of teaching MBAs it is hard for me to proceed in any other way).

But I think we can qualitatively take advantage of these results very nicely. The typical Boglehead 60/40 TSM/TBM portfolio is 85-90% dominated by a single factor, market beta. A move away from this dominance is a move towards improved portfolio efficiency.

If you're not different significantly from the average investor (weighted by portfolio size or trading volume, not the average person who invests) in an articulable way, the market has already done the work for you and produced a portfolio that can be appropriate for you. It's computed the various benefits from diversification and other elements of portfolio construction. Fans of size and value usually have reasons that would apply to pretty much everyone. If you are sufficiently different, then adjustments can be appropriate. How to gauge differences from the average investor (as defined) is not trivial, but if your reasons for picking independent risks are applicable to a wide swathe, then differences are not likely to be massive. This i...

In a world of efficient markets and rational investors, not only would correlations increase, but the "better portfolio" would become the cap-weighted market portfolio, where the better portfolio was some non-cap weighted mixture (VTI plus international or whatever). The process would be buying the diversifier, driving up its price and selling everything else, decreasing those prices, all the while increasing correlations. The process would continue until equilibrium is reached. Market efficiency is most probably a necessary condition to this process, but rational investors is much less clear. You certainly don't need everyone to be rational. All this suggests that the search for low correlation diversifiers that will improve a p...

It's why diversification is so critical in retirement.

And what I find is that many people seem to not appreciate that diversification may well be most important over the short run; and the importance is amplified in that period around early retirement. For example, if someone retired within the last year or two, he would have blunted his withdrawal pain with a value tilt.

Completely agree. Which is why at retirement I will have a TIPS LMP that meets essential expenses that SS/pension will not. If that means my overall assets are at 25/75, so be it.

I don’t benchmark my portfolio. I’m apparently a huge factor junkie. But I do believe markets are highly efficient and thus my passive funds do no market timing or individual security selection. I strongly believe that I get what my factor exposures give. The factors I’m exposed to are overwhelmingly market, size, value, quality, momentum, term. How I would do relative to any benchmark depends on how my collection of factor exposures compares to some benchmark’s factor exposures.
Now that being said, I can’t help but look every day at how Int, size, value, bonds compared to VTSMX. Just sort of a game I play with myself. Admittedly way more often than not my highly torqued funds have lost that game 2009-2021ish

To me it was always intuitive that small caps should do better, cause they can more quickly double etc their profits. A lemonaid stand can quickly double its profits, which something like Walmart can't do. But I think the argument that counters mine is efficient market theory. The market knows the stand can double its profit so the market prices that into the price of the lemonaid stand stock. Even if profits double, the price of the stock does its own thing in anticipation and as time goes on. So is my only way of being right that small cap is better, due to mistakes or inefficiencies in the market? If a doubling of profit isn't factored into the stock price, there definitely could be a small premium. But is there more to it beyond ineffi...

Yes. Value stocks and especially small value have a wider dispersion of potential outcomes than the market. For instance over rolling decade periods expected annual return might be something like 4-10% for the market and 2-15% for small value. The longer the time period the more likely small value is to out-perform the market, but in the short-term there's more risk. However, SV is imperfectly correlated with the market, so I would argue provides beneficial diversification. On it's own SV is riskier though. This is a good example of why diversification across unique and independent sources of return is likely even more important the shorter one’s time period is.

Took me a while, but I found a transcript of the interview on the internet. He was talking in the realm of lifecycle investing. He was comparing a young person starting out his investing career to an individual in retirement. Basically, as we age, we trade human capital and future employment income for financial assets. As we age and have less future work related income and our financial assets are at big risk and possibly can’t be replaced. “Three Mile Island Toxic” was just referring to the high risk nature of all stocks/stock markets.

Once a portfolio is on autopilot, the increased complexity is really no harder to manage. Moreover, accumulated small seemingly insignificant improvements, could potentially move the needle significantly. Dave In this case, we can only know it’s an improvement in hindsight.
