Lessons From Warren Buffett: Warren Buffett Disagrees With Beta as a Measurement of Risk

Beta, the measurement of a stock’s volatility, is not a measurement of riskiness, according to Warren Buffett. Although many investors are taught that high beta stocks have more potential for gain but also a higher risk of loss due to their volatility, Buffett disagrees.

“It became very fashionable in the academic world, and then that spilled over into the financial markets, to define risk in terms of volatility, of which beta became a measure, but that is no measure of risk to us,” Warren Buffett said at the 1994 Berkshire Hathaway Annual Meeting. “Interesting thing is that using conventional measures of risk, something whose return varies from year to year between plus-20 percent and plus-80 percent is riskier, as defined, than something whose return is 5 percent a year every year. We just think the financial world has gone haywire in terms of measures of risk.”
