John Bogle founded Vanguard and the index fund movement. Put simply, cost-conscious modern financial advice is to buy index funds, which track the performance of a large selection of stocks usually grouped by market cap, and hold on to them for a long time as they appreciate over time. This theory is based in part on Bogle’s own research.
Jeremy Siegel sees some weakness in not the fundamental theory, but in the way in which indexes are implemented. This article in USA Today interviews Bogle and Siegel, and illustrates their opposing viewpoints. Siegel:
I remember when Yahoo went in (to the S&P 500) in December 1999 that it was already overpriced. I was holding a lot of Vanguard Index 500 fund and I said, “Oh my God, what am I buying? Is there any way out of this?” That’s when I started to think about alternative indices that might not overweight these stocks that we know that people in speculative bubbles will overweight.
By the time stocks are entered into the S&P 500 Index, they’ve already proven their worthiness or have gained too much popularity. Those investing in an index fund tracking the index, like VFINX, are introduced to the newly-included stock after its price run-up.
Irrelevant, I’d say, what we’ve earned in that short period of time. What is relevant is what the fund actually has delivered. I’m not talking hypotheticals here. I ran into a real live investor in the fund, a charter investor, bought 1,000 shares for $15,000 when the underwriting took place in August 1976… That $15,000 is now worth $461,771. That’s a return of a little over 12%…
Siegel’s solution (to the problem Bogle doesn’t think exists) is to weight stocks in the fund based on dividends offered or earnings. Companies giving back to the shareholders and performing well represent a larger percentage of an investment in the fund than companies slower to perform or reinvesting their earnings.
Jeremy Siegel’s company, WisdomTree, offers index exchange-traded funds not quite as popular as the index mutual funds offered by Vanguard, based on this philosophy. One of the more popular Siegel ETF is the WisdomTree Total Dividend Fund (DTD). Year to date, DTD is outperforming VFINX.
