Using Volatility Forecasts to Trade Options and Volatility Swaps

Article Quant Q&A · Author: Tom Smith
Read the original

Summary

The document explains how a volatility forecast can inform trades in volatility-sensitive instruments. A trader who expects realized volatility to exceed the market’s expectation may buy options; a trader expecting it to be lower may sell options. It also identifies volatility swaps as a direct way to take a view on volatility, where available, and options as a possible proxy when swaps lack liquidity.

The discussion is conceptual and offers no data, backtest, or guidance on measuring whether a forecast is better than market-implied volatility. Profits depend on the forecast being right relative to what is already priced, and the brief answer does not address option Greeks, transaction costs, position sizing, or the risks of selling options. It notes that ordinary futures prices are generally less directly affected by volatility, while volatility futures are an exception. The material therefore outlines possible instruments rather than providing a complete trading strategy.

Key ideas

  • Volatility forecasts can guide positions in instruments whose values are sensitive to volatility.
  • Buying options may benefit when expected volatility exceeds the level reflected in market pricing.
  • Selling options may benefit when expected volatility is below the market’s expectation, if the forecast is correct.
  • Volatility swaps offer a direct exposure, while options can serve as a proxy if swaps are illiquid.
  • Ordinary futures are described as less directly affected by volatility than options or volatility futures.

How is volatility useful - from a purely profiteering perspective?

The most straightforward would be trading volatility swaps. If not liquid you can create a proxy for being long/short volatility using options such as calls/ puts for example.

If you think volatility is going to be higher than other people think, and you are right, you can make money by buying options. If you think volatility is going to be lower than other people think, and you are right, you can make money by selling options. So all those who trade options (and other derivatives that resemble options) are highly concerned about volatility.

Futures prices are not much affected by volatility, with one exception of course: volatility futures
