Jared Woodard explains how you can use a common but very reliable metric to measure the relative value of a given option trade.

Every option trade or investment is an instance of a more general schema, an “if, then” statement: “Because of q, I believe that p, so I will risk some money to make a profit if p is true.”

The proposition could be about anything: it could be about the value of a company, the yield of a crop, or the outcome of a football game. Every case in which you risk some capital in order to profit from a future event is composed of the two activities mentioned in that schema: the process of forming a belief, and the process of risking capital on the outcome of that belief.

Structuring a desirable trade and executing the trade in the marketplace is the second process. I have written about that second process before in the context of options: the idea is that options are an essential part of any investor’s tool kit, because they allow you to express much more complex views and to express them more precisely than can typically be done with stocks or futures alone.

Buying or shorting shares of stock lets you say “yes” or “no” about a company. Structuring a position with options lets you say things like, “Yes, but only to the following extent, and before this date, and only under the following conditions...”

A lot of the educational material published about options trading tends to focus on the execution side. You can learn pretty easily about the kinds of option spreads that traders use, various order types, and so on.

But all of that instruction about how best to express your belief that assumes that you already have a carefully defined, highly informed belief that you want to express. You might not! Where do such beliefs come from, anyway? It’s not a trivial matter to look at some asset and form an idea about which you’re confident enough to risk real money.

The first process, the process of analysis, is where you form a risk-worthy belief. This is the “because of q” part of the schema above. The two most common ways that people find reasons that justify a trade are by analyzing the fundamental economic properties of assets and by studying the past price behavior of assets.

Fundamental and technical analysis, as they’re known, are by now so familiar and so easy (relative to past decades) that they are in danger of becoming trivial. A simple moving average applied to a chart or a simple filter of price-to-earnings ratios will no longer reliably produce market-beating returns, if they ever did.

A third source of information about the perceived and likely value of assets is the options market. What we might call volatility analysis is a source of data that any investor (but especially options traders) can use to form justified and risk-worthy beliefs.

Volatility analysis is a big tent, including the study of implied and historical volatility time series, of models used for forecasting asset volatility and for pricing contracts, and of order flow as an indicator of future returns and market shifts.
