Jack Bogle (1929–2019)


Bloomberg writes:

Bogle founded Valley Forge, Pennsylvania-based Vanguard in 1974. Investors attracted to its low fees helped the firm overtake American Funds, managed by Los Angeles-based Capital Group Inc., in 2008 as the biggest U.S. stock and bond fund manager. Vanguard has $4.9 trillion in assets under management.

The free dividend fallacy could be costing you

  • The free dividend fallacy could be costing you

We show that many individual investors, mutual funds and institutions trade as if dividends and capital gains are separate disconnected attributes, not fully appreciating that dividends come at the expense of price decreases. Behavioral trading patterns (e.g. the disposition eect) are driven by price changes excluding dividends. Investors treat dividends as a separate stable income stream, holding high dividend-yield stocks longer and displaying less sensitivity to their price changes. Demand for dividends is systematically higher in periods of low interest rates and poor market performance, leading to high valuations and lower future returns for dividend-paying stocks. Investors rarely reinvest dividends into the stocks from which they came, instead purchasing other stocks. This creates predictable marketwide price increases on days of large aggregate dividend payouts, concentrated in stocks not paying dividends.
