Aha! Indexing > isn't dead! comparing a managed fund against an index . On a pure price basis in the 7 years from 12/31/1998 to 12/31/2005 the S&P 500 was unchanged and the Russell 2000 was up over 60%. You can beat the S&P 500 with the S&P 500 stocks just by equal weighting them. From multiple sites: "The equal-weight S&P 500 has held its lead over the past decade, gaining 11.9% annualized versus a 9.1% average yearly rise for the cap-weighted index, according to S&P." |

Just intuitively...you look at the "fund comparison vs. S&P 500" kinds of charts and you'll see much higher percentage of "winning" numbers on the one-year data than on the three year, five year or ten year. Because of that basic problem of "performance not repeating." Now if they run the data right it should account for this but I'd need to look at exactly what they're doing. I wonder if this study is basically compounding forward all those one-year figures, while ignoring the fact that a given fund subsequently underperformed. It seems it depends on how they do their asset weighting. If a fund lost 50% do they asset-weight that (-50%) return based on the initial assets, or do they underweight it based on the lower, end-of-period asset levels? Do they look at all at fund inflows/outflows to see how many dollars experienced posted returns? There's this tendency towards buying into gains with actively managed funds. Devil's in the details! I'm also curious about their choice of 1/75 as a start date - just after some very big losses. I don't know the effect of that but as the article itself notes (so did Buffett's latest letter to shareholders) the choice of a start and end date can lead to dramatically different results. Also - they take as a given that CRSP 1-10 and S&P 500 are interchangable, citing "discussions with academics." Essentially they seem to be using the one-factor model rather than the three-factor model to adjust for risk. Over the period they cited I ran these two against each other and the standard deviations and geometric returns are close. But I don't consider these interchangable. There were substantial discrepancies along the way and again, they're picking a certain start-end date where the two happened to line up over the long haul. The assumption tacitly implies that there's no small-company risk, and Fama's Nobel suggests otherwise! =) I saw also the language Elle quoted but a sentence a bit later seems to contradict that - it's unclear to me exactly what investment costs, they incorporated into the analysis. Maybe if it's rainy this wknd I'll give it a closer look... -Tad |

By computing the standard deviation of the S&P 500 index vs. thestandard deviation of the average return of managed funds. I only skimmed the article before, but a quick read-through shows that the author did not actually adjust the returns, but concluded that the standard deviations were nearly the same, so the risk was comparable. -Will |

For example, I presume there are some high grade bond funds that beat the S&P 500 for a few years. That doesn't mean one should put all one's money in high grade bonds. I thought the following was interesting, and will take its basic argument to be true (based on other reading) until further notice: In a recent study of 147 large investment funds, researchers studied the contribution of stock picking, market timing, and asset allocation to long-term returns. What percentage of returns was the result of asset allocation, as measured by a portfolio of index funds? A. more than 95% B. 70% C. 50% D. 30% E. less than 5% Correct answer is A, or so claims http://www.indexfunds.com/ (click on "Risk Capacity Survey"). |

A good starting point would be seeing whether the numbers on which you base the premise are accurate, they don't look right to me (though I don't keep 7-year data at my fingertips!). Where are those from? Do they correct for survivorship bias, or just show the returns of the funds that still exist now? How do they "adjust for risk"? My 5 and 10 year numbers show the usual - active funds lagging once you adjust for their asset-class risks - even without factoring in survivorship bias. -Tad |

| OK, so the subject was a bit dramatic, but the average managed U.S. equity mutual fund has now beat "the market" for seven years straight, and that's after adjusting for risk. Of course, "the market" here is defined as the S&P 500 which is not really "the market". The Wilshire 5000 may be a better benchmark, but the average managed fund beat that, too last year (Average managed fund: 6.7%, W5000: 6.4%, SP500: 4.9%). It may not be fair to compare all managed funds against the S&P (or Wilshire). One could argue (correctly, I think) that managed funds should be compared against the benchmark for their investing category. If you do this, you'll see that managed funds on average almost always get killed (I'm looking at 1, 3, and 10 year data). Aha! Indexing isn't dead! I myself have been an advocate of indexing, and in particular indexing with an S&P 500 fund. But perhaps a better strategy is to build a market weighted portfolio of managed funds, that apparently would beat the S&P 500. Is this practical? How would one go about this? Or is seven years too little data to be formulating this kind of strategy? Maybe the strategy would be even better by buying index funds across investment categories with the same weights as managed mutual funds (e.g if 3% of the total money in managed U.S. equity funds is in microcap funds, 3% of my portfolio should be in a microcap index). Just tossing around some ideas, what do you think? Thanks in advance, -Will |
