Hey everyone. This is Kirk here again from Option Alpha and welcome back to the daily call. Today, we're going to answer the question – "How does volatility affect option prices?" Volatility is this thing that most people really don't understand when it comes to option pricing in the options market. And it's really as simple as this. When implied volatility or the expectation of volatility in an underlying stock increases, option prices on both sides, calls and puts, increase as well. When implied volatility or the expectation that the underlying stock is going to see a decrease in volatility, then the underlying option contracts on both sides, calls and puts, decrease as well. And another way of just looking at this is just to use maybe a real estate analogy. And if you're going to buy a property in New York or San Francisco or Miami or one of these hot markets right now, there's a pretty good chance that you're going to see a wild swing in the price of that property and therefore, the price of that property is very high because there is an opportunity, maybe not a good opportunity, depending on how you look at it, but there's an opportunity that you could see or realize a huge profit potential in an underlying property that you're buying because of the real estate market continuing to go up, but at the same time, you could see a huge swing to the downside. There's a lot of risk involved in this, but obviously, those real estate markets have the highest prices of properties because the value is in the expected growth in the future, this baked in or embedded growth potential or growth expectation that people have about the area, the real estate market, this suburban urban area, etcetera, etcetera. Now, you look at a piece of property, say where I'm from, outside of Pittsburgh in Pennsylvania and pretty much no man's land and property prices don't really move. There's low volatility in property prices. We might have a house that'll sell for $115,000 and the next month or year, it might sell for $113,000. It's just not a big move in housing prices and that's because there's really no expectation of a massive increase in prices for some economic event in the future. There are towns and our towns that we live in are pretty stable, pretty small, rural areas and so, there's not a lot of expectation of these big, huge price swings, so real estate market prices reflect that.
In the world of options trading, the same thing is held true in the sense that if you're trading options on an underlying stock and there's a huge expectation of some volatile event happening in the future, it could be earnings, it could be an FDA announcement, it could be a number of different things, but there's an expectation that we're going to see prices go up or down dramatically which creates an opportunity to potentially make a lot of money, depending on which side of the contracts you're on, that in and of itself is valuable. Volatility is a valuable commodity. If you're going to trade something and there's an expectation that it could have a huge swing in price which could lead to a huge potential profit, well, then that underlying contract is more valuable than a similar contract where there's not a big expectation that the stock is going to make a huge move. Typically, like a utility stock or say an industrial stock that's just such a big corporation or such a big underlying product and it's not going to have these huge moves, well, you're not going to have option contracts that are priced at these exaggerated levels because the stock really isn't going to move. Maybe it fluctuates a couple percent every month, but it's not having these run-ups of 10% and drawdowns of 20% and run-ups of 30%. Option prices are absolutely affected by the expectation of volatility. When the market expects a lot of volatility, option prices get bid up because that is valuable. And when the market has low expectations of volatility, then option prices fall because there's no perceived value in buying those contracts when the market is not really going to move. Hopefully this helps out and again, I wanted to use a little bit different analogy because we talked about this concept a couple times before, but I wanted to try something a little bit different and hopefully it helps out. If it did, let us know in the show notes or over on Option Alpha, Facebook, Twitter, YouTube, etcetera. Just let us know. Add a comment and let me know if this helped out. Until next time, happy trading.
