Options trading has become very popular in recent years. Did you read the post on how to get paid for buying your favorite stock? In this post you learn an options trading strategy that you can use to buy your favorite stock at a lower price. Options are a type of derivatives. Derivatives r options trading been hailed as the financial revolution of the late 20th century.
Derivatives types are forwards, futures, swaps and options. Derivatives are instruments that derive their value from another underlying asset. In the case of stock options, their prices depend on the underlying stock. In this post first we will build two options pricing models. The first one is the famous Black Scholes Options pricing model and the second one is the Cox-Ross-Rubinstein Options pricing model, r options trading.
After that we will also discuss what options greeks are and how to model implied volatility. We will also discuss why in practice both these options pricing formulas are used in reverse to calculate implied volatility instead of options price.
We will be using R for doing the analysis. You should have installed R and RStudio. I would suggest if you fast a very fast implementation, r options trading, you should install Microsoft R Open. Quantmod is an important R package that provides technical analysis. Read this post on how to use R package Quantmod in daily stock market analysis.
Options as said above drive their value from the underlying stock. This brings a level of complexity when we try to price the stock options contract. Black Scholes formula assumes a continuous stochastic process while Cox-Ross-Rubinstein model assumes a discrete stochastic process. Read this post on fail safe EMA trading system. Black Scholes options pricing formula makes a few assumptions.
The first is market is arbitrage free. This means that there is no price differential possible. The second assumption is that the underlying asset price follows a Brownian motion, r options trading. The third assumptions says that the underlying stock does not pay any dividend., r options trading. Fourth assumption is that there are no transaction costs involved and buying and selling of the underlying stock can be done in any fractional amount.
The last assumption is that we know the short term interest rate and this interest rate is constant over time. We will use R for calculating the stock options price when we know the different parameters used in calculating the stock options price.
Below we use R to calculate Apple AAPL stock call option price with expiry 3 months. First we load the fOptions library, c means call option. This is how it works, r options trading. We buy a call option, r options trading. R options trading you can see we can buy Apple stock cheap.
We just assumed an implied volatility formula. We can also calculate put options price. It is also very easy when r options trading R. Below is a put option price calculation. We changed c to p in the formula. Expiry is 3 months.
Now as said above Black Scholes Options pricing formula depends on implied volatility a lot. Most of the time we use the formula in reverse. We plugin in the stock option price in the formula and calculate implied volatility.
We can use the GARCH model to calculate volatility. Read this post on how to use GARCH in trading. Cox-Ross-Rubinstein formula also known as CRR formula is different from Black Scholes Stock Options pricing formula.
The fundamental assumption in CRR formula is that the underlying stock price follows a discrete binomial distribution. What this means is that stock price either moves up by a certain amount or moves down by a certain amount in each period.
The binomial tree is recombining. What this means is that in 2 periods, price can go up and then down or it can go down and up with the same end price. Below is calculate Apple stock options price using the same strike price, implied volatility, short term interest rate as above for Black Scholes formula.
You can see options prices using Cox-Ross-Rubinstein formula are close to Black Scholes formula but not the same. We can also plot the above call options formula as well the put options formula binomial tree for r options trading periods. Below is the code for call options binomial tree. By changing ce to pe we can also plot the put options binomial tree. Read this post on how to do Principle Component Analysis on Dow Jones Industrial Average DJIA.
Below is the call options binomial tree plot. Now you saw a difference in options price between the both formulas, r options trading. The price difference is not much. The difference is not great but it is there. It is due to the difference in the two formulas mathematical derivations. In Black Scholes formula we assume a continuous stochastic formula while in Cox-Ross-Rubinstein formulas assumes a discrete binomial formula. W can reduce r options trading price difference by reducing the length of the time step in Cox-Ross-Rubinstein formula.
Greeks measure sensitivity of an options contract to different market factors. For example delta is the sensitivity to underlying stock price. Gamma is the sensitivity to delta to underlying stock price. You can call gamma delta of delta. Theta is sensitivity to time while rho is sensitivity to risk free rate. Lastly vega is the sensitivity to implied volatility, r options trading.
In mathematical terms all the greeks are partial r options trading that measure the rate of change with respect to some parameter. Below we calculate the greeks using R. You can see R is very fast in calculating the greeks. Straddle is an important options trading strategy, r options trading. We construct a stradde by buying a put and a call option at the same time. Below is the delta calculations for a straddle. I have developed this r options trading on Econometrics for Traders in which I show you how you can use econometrics in your trading.
Below is the delta plot for this straddle option build with Apple stock put and call options. If you are interested, you can take a look at my course Stochastic Calculus for Traders. In this course, r options trading, I show you how to mathematically derive Black Scholes options pricing formula as well as Cox-Ross-Rubinstein options pricing formula. Previous r options trading.

In very simple terms options trading involves buying and selling options contracts on the public exchanges and, broadly speaking, it's very similar to stock trading. Whereas stock traders aim to make profits through buying stocks and selling them at a higher price, options traders can make profits through buying options contracts and selling them at a higher price 16/06/ · “sa_work.R” is the file where you would normally work.
