Guide to Options: To hedge the investment position

If you’re in the financial market for quite some time or involved in trading and investment, you might have heard about derivative.


Derivative is a vast topic which is often used to speculative and hedge investments. If you know about fund managers, you might know that they often use derivative products like options in order to hedge their investment position. Derivative comprises of various investment products like forwards, futures, options and swaps. However, today we’ll discuss in detail about options.



James Chanos said- Derivatives in and out of themselves are not evil. There’s nothing evil about how they’ve accounted for, and how they’re financed, like any other financial instrument if done properly. An option is a financial contract which gives the buyer the right but not an obligation to buy or sell the underlying asset at an agreed upon price on or before a specified date. In short, it is used as a hedging instrument.




Let’s understand this with the help of an example. Since predicting weather conditions is really a difficult task, hence the farmers had to hedge their position to bad weather. So farmers purchase the derivative contract in case the crop gets damaged due to bad weather. However if the weather is good, he just looses the cost of purchasing the contract. In short, it’s very similar to buying an insurance policy.



Types of options




1. Call option


It gives the holder the right, but not the obligation to buy an underlying asset at an agreed upon price for a certain interval of time. Investors often buy call option when they are expecting the price to rise in the near future, while they’ll sell the call if they are expecting a decline in the share price. However, if the stock fails to meet the strike price before the contract expiration, the option expires and will be of no value.




Say the stock of VIP industries is presently trading at Rs 100 per share. Assuming a call option buyer purchases one unit of call option at Rs 3 per unit. On the expiry, say the stock is trading at Rs 120, so the call option buyer ends up making a profit of Rs 17 (120-100-3). On the other hand if the price on expiry would have been Rs 99, he would have lost only Rs 3 i.e. premium value.




2. Put options


It gives the holder the right to sell at an agreed upon price but he’s obligated to buy the stock at the exercise price. It can be exercised anytime before the expiry of the contract. So investor with the view of decline in stock price will buy put or sell if they think that the price will rise.


Say the stock of VIP industries is presently trading at Rs 100 per share. Assume that an put option buyer purchases one unit of call option at Rs 2 per stock. On the expiry say the stock trades at Rs 80, so the call option buyer ends up making a profit of Rs 18 (100-80-2). On the other hand if the price on expiry would have been Rs 105, he would have lost only Rs 2.


In both the scenario, the maximum loss to an option buyer is limited to the option premium while the profit may be unlimited. But in case of option seller, the maximum profit is limited to option premium and the maximum loss can be unlimited.


The concept of hedging is very similar to buying insurance. It’s a protection with regards to unforeseen events but you never wish to use it.



Option styles



The most common option style are discussed below.




a. American option




It is an option which can be exercised on before maturity, thus increasing the value of option.



b. European option




It can be exercised only on maturity.



Options strategies




1. Straddle


There are many option strategies and you can create your own strategies to trade in options. However, the most common ones are discussed below.



It is an options strategy where investor holds a position simultaneously in call and put with the same strike price.








2. Strangle


It is an option strategy where the investor holds position simultaneously in both call and put with different strike prices but with the same maturity. It is profitable only when there is a large movement in the price of the underlying asset.









3. Butterfly


It is a limited risk, neutral option strategy which combines four option contract with the same expiry.


However selling a straddle would provide a trader greater opportunity to profit as compared to a butterfly if the final stock price is near the exercise price but it may even result in a large loss.





4. Iron Condor


It involves a call spread and a put spread with the same expiration with four different strike prices.






5. Covered call


It is an option strategy where investor holds a long position in an asset and writes call options on that same asset to hedge the downside risk to certain extent.





6. Protective put


It involves taking a long position in an asset and buying put option on that same asset. In this case the only risk involved is limited to the amount of premium.





Option valuation


When you will develop an option strategy, there will be risk and reward from change in price, changes in volatility and time decay.


In a very simple term, the value of option can be categorised into two parts.



a. Intrinsic value: It can be defined as a difference between the market value of the underlying asset and its strike price.



b. Time value: It refers to decrease in the value of underlying option premium with the passage of time.



Option Greeks


The change in option price may take place on account of directional price shift in the underlying asset, time decay or change in implied volatility. The understanding of option’s sensitivity to greeks can be very helpful and can improve your trading in options. The concept of greeks comes from Black Scholes model. Most buyers are concerned with Greeks like theta, delta and vega.



Let’s understand them one by one.




a. Delta




It measures option’s sensitivity wih the change in the underlying stock price. It can be used both in buying and selling oppurtunities.




b. Theta




It measures options sensitivity to time. It measures the decay in time and gives us rupee value of day per day. There is a significant decrease in value as the option reaches towards expiration. On the other hand, option writers use theta to their advantage.



c. Vega


It measures options sensitivity to a change in implied volatility. There will be an increase in the value of option premium with the rise in implied volatility.




d. Gamma


It measures the sensitivity of delta to a change in the value of underlying asset. In simple terms, it is the change in the value of underlying asset and it is more closely tracked by people who sell options since it provides an indication of the risk exposure if the price moves against your position.



e. Rho


It measures option’s sensitivity to a change in interest rates. So any increase in interest rate may decrease in the value of option since it will increase the cost of carrying the position.



Margin requirement



When anyone is buying options, he just needs to pay the premium so as to enjoy the right. But in case of writing (selling) options, the person has to deposit the margin amount either in cash or securities kept as collateral.


The margin requirement in case of writing options is similar to futures. The minimum margin requirement is usually between 5% and 10% of the contract size. However the margin amount may even be raised during the period of increased volatility. Margin requirements also vary by option type.


Also, some options trading strategies requires no margin since the underlying stock can be used as  collateral. Both covered calls and covered puts have a margin requirement.







One thing which you should keep in mind is that options are sophisticated trading tools and so you should be educated and capable enough to handle it, otherwise the consequences can be dangerous.
