Here I detailed why P/E is useless…

And today I’m telling you why beta is useless as well.

Like P/E, Beta is another completely useless investing metric.

In the 11 – minute video above, I detailed the following reasons why beta, like P/E, is completely useless.

Why it’s useless
What it measures – supposedly
Why volatility does not equal risk
Why I NEVER use it
And more…

And if you want to learn more about what two of the greatest value investors ever, Warren Buffett and Seth Klarman, say about beta, click here.

Here are Klarman’s thoughts on beta from the article: excerpt from his book Margin of Safety…

“I find it preposterous that a single number reflecting past price fluctuations could be thought to completely describe the risk in a security. Beta views risk solely from the perspective of market prices, failing to take into consideration specific business fundamentals or economic developments. The price level is also ignored, as if IBM selling at 50 dollars per share would not be a lower-risk investment than the same IBM at 100 dollars per share.
Beta fails to allow for the influence that investors themselves can exert on the riskiness of their holdings through such efforts as proxy contests, shareholder resolutions, communications with management, or the ultimate purchase of sufficient stock to gain corporate control and with it direct access to underlying value.
Beta also assumes that the upside potential and downside risk of any investment are essentially equal, being simply a function of that investment’s volatility compared with that of the market as a whole. This too is inconsistent with the world as we know it. The reality is that past security price volatility does not reliably predict future investment performance (or even future volatility) and therefore is a poor measure of risk.“
