Key Takeaways Volatility skew describes the observation that not all options on the same underlying and expiration have the same implied volatility assigned to them in the market.

Part Of. In theory, how should volatility affect the price of a binary option? A typical out the money option has more extrinsic value and therefore volatility plays a much more noticeable factor. Now let's say you have a binary option priced at. How much does volatility affect this price? Volatility can be high in the market, inflating the price of all options contracts, but would binary options behave differently? I haven't looked into how they are affected in practice yet, just looking to see if they would be different in theory.

Also, the CBOE's binaries are only available on volatility indexes, so it gets a bit redundant trying to determine how much the "value" of volatility affects the price of binary options on volatility. Generally that terminal distribution will be lognormal from the Black-Scholes model, or close to it.

Option price is. Volatility widens the distribution and, under the Black-Scholes model, shifts its mode a bit. Generally speaking, increased volatility will. Increase the density in the "payoff region" for out-of-the-money options, thereby increasing their theoretical value. Assuming your option was worth 0. Increase the density in the "no-payoff region" for in-the-money options, thereby decreasing their theoretical value. An option now worth 0.

Therefore, out-of-the-money calls will take on a maximum value at some volatility that concentrates as much probability as possible below the strike before concentrating the distribution too close to zero. Edit : A huge thank-you to Veeken to pointing out that it is out-of-the-money calls, rather than puts, which take on a maximum theoretical value. all of the volatility effects on a binary option struck at with a one dollar payoff are approximately the same as the volatility effects on the following portfolio of options:.

In the second link, the 'no skew' call price is negative - call prices actually decrease as strike increases.

So it is clearly absurd. I'd go with wikipedia. If I need to be a bit mathematical, the first derivative of the call option payoff w. t strike is exactly the NEGATIVE OF the random variable that represents the payoff of the binary - this should be obvious once you write the at expiry payoff not today's price of the call and differentiate w. t strike. Go to the T forward measure, take expectations and you find that you can price to the extent that your first derivative is accurate the binary as a call spread, with short the higher strike and long the lower strike.
