I really like the way this article describes how Warren Buffett thinks about cash. I think of it similarly (see below), but I never thought of it as a call option. It says:
“Ms. Schroeder argues that to Mr. Buffett, cash is not just an asset class that is returning next to nothing. It is a call option that can be priced. When he thinks that option is cheap, relative to the ability of cash to buy assets, he is willing to put up with super-low interest rates, said Ms. Schroeder, who followed Mr. Buffett for years before she became his biographer.
“He thinks of cash differently than conventional investors,” Ms. Schroeder says. “This is one of the most important things I learned from him: the optionality of cash. He thinks of cash as a call option with no expiration date, an option on every asset class, with no strike price.”
It is a pretty fundamental insight. Because once an investor looks at cash as an option – in essence, the price of being able to scoop up a bargain when it becomes available – it is less tempting to be bothered by the fact that in the short term, it earns almost nothing.
Suddenly, an investor’s asset allocation decisions are not simply between earning nothing in cash and earning something in bonds or stocks. The key question becomes: How much can the cash earn if I have it when I need it to buy other assets that are cheap, versus the upfront cost of holding it?”
