What implied volatility is actually telling you — and what it isn't

Implied volatility is one of the most quoted and least understood numbers on a trading screen. It is not a forecast of direction, and it is not a promise of movement. It is a price — the market's current cost for a specific kind of protection — and like any price it can be too high or too low.

IV is a price, not a prediction

When you read that an option is trading at 18% IV, you are reading what buyers and sellers have agreed the option is worth today, expressed in the language of annualised volatility. It reflects supply and demand for that contract, not a view handed down about where the underlying is going.

The three ways it is most often misread

First, treating a high IV as a signal that a big move is coming — when it usually just means recent demand for hedges. Second, comparing IV across two names as if the number were absolute, when it is relative to each underlying. Third, ignoring the term structure entirely, and paying front-month prices for a back-month view.

The number is real. What you infer from it is where the mistakes live.

None of this makes IV useless — the opposite. Read against realised volatility and against its own history, it is one of the more honest gauges a trader has. The discipline is to treat it as a price to be assessed, not a verdict to be obeyed.
