Asset Allocation – A Convenient Cop-Out for Pension Fund/Wealth Managers?
The Asset Allocation Approach – we have all heard about how it is the most rational way to invest. But is it? And why do investment managers like it so much? This article reviews the arguments for the approach and why it is a favorite of wealth managers.
Today’s dominant investment theory is derived from the writings of the mathematicians and philosophers of the 16th Century. Paul Samuelson is credited with developing the mathematical theorem that “properly anticipated futures prices fluctuate randomly”. And Burton Malkiel has presented all of this work in a book with direct application to personal investing.
And what does it all mean for the investor? It means that the best assumption to start with is that all available information on companies is reflected in their stock prices. Consequently, the price of every stock is just as likely to go up or down. When you invest, you are making a random bet. When new information comes out, prices will adjust immediately to reflect the implications of this information.
This means the investor has 50-50 chance of picking which way a stock will move – not a good bet because you don’t want a 50% chance that you will lose money on your investment. The sensible conclusion: Don’t bet all your money on one horse: diversify; the more you diversify, the more your chances of losing (or making) money on your investment will fall. And you can diversify by purchasing more stocks, or a mutual fund or an ETF.
There is an important corollary to this: stock recommendations are close to worthless for the retail investor: if new information is almost instantly reflected in stock prices, what makes you think you are going to get that information in time to “cash in”? For more on what the retail investor is up against, see my recent article.
The logic for using an asset allocation strategy is very powerful.
The Sector Scam
The people who want to charge you a fee to have them manage your money have taken the meaning of diversification further. They have developed categories for stocks/bonds. They say proper diversification requires that you have holdings in various sectors/categories. To give a sense of how far the sector/category business has developed, the following are most of the categories used by Morningstar to describe the approximately 25,000 mutual funds in their database:
Bank Loan, Bear-Market, Conservative Allocation, Convertibles, Diversified Emerging Mkts, Diversified Emerging Mkts, Diversified Pacific/Asia, Emerging Markets Bond, Europe Stock, Foreign Large Blend, Foreign Large Growth, Foreign Large Value, Foreign Small/Mid Growth, Foreign Small/Mid Value, High Yield Bond, High Yield Muni, Inflation-Protected Bond, Intermediate Government, Intermediate Government, Intermediate-Term Bond, Japan Stock, Large Blend, Large Growth, Large Value, Latin America Stock, Long Government, Long-Short, Long-Term Bond, Mid-Cap Blend, Mid-Cap Growth, Mid-Cap Value, Moderate Allocation, Money Market – Muni, Money Market – Taxable, Multisector Bond, Muni Single State Interm, Muni Single State Long, Muni Single State Short, Pacific/Asia ex-Japan Stk, Short Government, Short-Term Bond, Small Blend, Small Growth, Small Growth, Small Value, Communications, Financial, Health, Natural Resource, Precious Metals, Real Estate, Technology, Utilities, Ultrashort Bond, World Allocation, World Bond, World Stock.
Indicies and ETFs have been developed for most of these.
Callan Associates, an institutional money consultant, has chosen 8 sector indices. To show how these sectors have performed over the last 20 years, Callan has developed a chart with different colors for different indices. A great marketing vehicle: different colors are at the top in different years – the message – diversify – use our asset allocation method, and pay us for it!
Boeckh just did a nice, representative piece on asset allocation. The article focused on correlations between different sectors. Their message? Good asset allocation means holding sectors that are not highly correlated with one another. No discussion of specific investment vehicles.
Consider how convenient it is for investment advisors to focus on these sectors/categories. This focus diverts the client’s attention from the important questions:
- How has the portfolio performed?
- What stocks, funds, ETFs have actually been picked?
- How have these picks performed relative to other possibilities in the same categories?
A Case In Point
I recently received “Investment Reviews” from a major bank where I am a trustee on a Trust. The reviews were nicely presented in high-resolution color. The titles for the first four pages were:
- p. 1 – “Strategic Asset Allocation Models”
- p. 2 – “Hypothetical Model Portfolio Risk/Return”
- p. 3 – “Strategic Asset Allocation Philosophy”
- p. 4 – “Current Asset Allocation”.
There was nothing in these four pages on performance – nothing!
Only one page of these documents provided detail on performance, and that detail only broke down performance into three categories: “Equity”, “Fixed Income”, and “Cash”. But nowhere in the document was there any information on how each investment pick (stock or mutual fund) had done! Why? Because the Trust manager did not want me to focus on actual investment picks and how each pick actually performed.
The last few pages of “Investment Reviews” gave data on the individual investments, e.g., number of shares, market value, but without performance information on the individual investment.
It turns out that a significant portion of the Trusts were invested in the Bank’s mutual funds. I asked for and received performance data for these funds. I then compared their performance with mutual funds that fall into the same Morningstar categories.
The essence of my review is contained in the following table. Each of the funds picked by the bank fits nicely into Morningstar categories. Columns 2 provides the annualized 3-year return on each fund. Column 3 provides the three year return ranking of each fund in the Morningstar category. For example, in the Morningstar category of large cap growth, the Large Cap Growth fund of the Bank ranked 500. This means there were 499 funds in the Morningstar category that had better three-year performance than the Bank’s fund. Column 4 provides the best three year return for a fund followed by Mornigstar in the category. For example, while the bank’s large cap growth fund has an annualized three year return of 10.44%, the Morningstar fund with the best return for that category was 24.59%. Column 5 provides the differential between the best return and the return on the Bank’s fund.
|3 Yr Rank||3 Yr Best||
|Large Cap Growth||10.44||500||24.59||14.15|
|Large Cap Value||14.38||484||21.99||7.61|
|Mid Cap Growth||16.33||155||23.07||6.74|
|Mid Cap Value||17.79||60||26.18||8.39|
|Small Cap Growth||11.97||368||19.83||7.86|
|Small Cap Value||16.12||55||21.82||5.7|

This table demonstrates the sub-par performance of the Bank’s funds. The important message? Specific investment choices matter! Remember that the people who invest your money want to keep you as far away as they can from how your portfolio is performing. And most definitely, they don’t want you to know how well each investment pick is doing relative to other possible investment picks in the same category. Every wealth/pension manager has favorites in the investment management industry s/he wants to give your money to. In the case of the bank example above, the bank wanted to keep the money in-house by putting it in their crummy mutual funds.
In these circumstances, what to do?
- Asset allocation logic is quite powerful.
- Picking individual stocks should be viewed as gambling, a form of entertainment.
- Find an investment advisor that has an audited 3-year performance record s/he is willing to share with you (hard to find).
- Once you have decided on an asset allocation strategy, make sure to pick relatively high performing vehicles in each sector.
