Options trading 101

While many brokers have eliminated fees for trading stocks or exchange-traded funds ETFs , these still exist for options. Commissions may range from a flat rate to a per-contract fee based on the amount you trade—both when you buy or sell options. As a result, options traders must take into account these fees when considering the profitability of an options strategy.

Investing More from. By David Rodeck Contributor. By Rebecca Baldridge Contributor. The higher the volatility, the more expensive the option.

The latter is probably less intuitive than the former, as volatility can also take our option OTM. The thing about volatility, is that the lower bound of an option is 0 as in the worst case we will not exercise the option , but the upper bound is infinite the spot can go to the moon.. The higher the volatility, the more valuable the time value is as our option can go further deeper ITM, hypothetically speaking.

So we can comfortably say that all else being equal and that we cannot turn back time , the only real unknown in options is volatility. After we established that the our primary motivation in option trading is trading volatility we want to put that into use and see how volatility translates into the price of an option and how we can turn that into trading strategy. As we take no view on the direction we will trade ATM Straddle i. The cost of our ATM Straddle can be approximated the following way:. The explanation to why option price grows at the rate of square-root of time is related to the fact that although we talk and trade volatility, we actually trade variance as volatility is not additive.

Greeks are closed-form formulas that represent the sensitivity of the option to the different underlying parameters. These three Greeks are known as 1st order derivatives, as the value of the option is directly derived from a change in these parameters. However, there is one 2nd order derivative which is highly important for us as novice option traders:.

From now on, we move away from option price and the underlying asset and enter the matrix. Generally speaking, as options traders we care about two main Greeks:. Theta time decay and Gamma our delta sensitivity to the underlying spot change. Both Theta and Gamma are highly sensitive, you guessed right, to volatility.

As volatility traders this tells us at what PACE our delta will accumulate. Why is this important to us? If we BUY volatility, we want our gamma to be HIGH so we will accumulate delta faster, and our option price will increase at a faster rate. If we SELL volatility, we want the exact opposite. The higher the volatility, the lower the gamma and vice versa. Volatility-Theta — Theta represents the rate of which our option price decays loses value as a function of time passage.

The higher the volatility, the higher our theta i. The following chart shows the effect of volatility x-axis on both gamma and theta for a long ATM straddle note that theta should be negative, as our option value decays, but I made it as absolute value. Now that we understand the effect of volatility on gamma and theta, we will see how they affect our option trading profitability.

However, we can run the same calculation for different time intervals say 1-day , and get that our 1-day breakeven rates are This transformation shows that we can treat the straddle strategy or any strategy for that matter as a series of T-interval straddle breakeven. If we bought the straddle, we need the underlying spot to move MORE than the breakeven rate, while if we sold the straddle we need the underlying spot to move LESS than the breakeven rate Later we will see how dynamic hedging makes our trading far more interesting.

After two days of stale market our 1-day breakeven rates will be Now that we know how to price options, Greeks, and the magical triangle of Volatility-Gamma-Theta, we can move on to the real fun part of options — Volatility Trading. After we happily bought 1-week straddle thinking that the market will relive the glory days of March , the market started going sideways… 1. This is where dynamic hedging comes to play…. As we buy low and sell high, we profit from the market volatility via the dynamic delta hedging aka, gamma scalping , and offset the theta time decay.

The more volatile the market, the greater our hedging profits in other words, we realize above the implied volatility we paid. The below chart represents a theoretical randomly simulated path:. Although I tried making this write-up an introduction to option volatility trading, I barely scratched the surface of the world of options and volatility. That reminds me the early stage of my boxing experience. This resembles trading a lot, as any book no matter how good it is , cannot teach you how to manage and run the day-to-day risk of option trading volatility.

Option trading is a journey that can take many shapes and forms. It depends on our scope of interest, ability to learn new concepts, and adapts to everchanging markets.
