Introduction to Derivatives

A derivative is a financial instrument that derives its value from another financial asset.
For example, the value of a crude oil futures contract depends on the value of the underlying asset, which is crude oil itself. Derivatives come in all shapes and sizes, so let's discuss some of the most common ones. These are futures, forwards, options, and swaps.

The most common type of derivatives

Futures are perhaps the most common type of derivatives. When an investor enters into a futures contract, he agrees to buy or sell an asset at a predetermined price on a particular date in the future. For example, today is 1st July and the spot (current) price of gold is US$ 1,000. A three month gold future (expiring 1st October) is trading at US$ 1,010. As an investor, I believe the price of gold is going to rise over the next three months, so I enter into a long futures contract at the current futures price of US$ 1,010/oz. Fast forward to 1st October, and the gold spot price is US$ 1,100. I earlier agreed to purchase gold in three months at US$1,010 and now the market price is US $ 1,100, so I have made a profit of US$90. Similarly, if the gold price had fallen below US$ 1,010 on 1st October, I would have incurred a loss equal to the difference between the initial futures price and the final spot price.


A close cousin of the futures

Forwards work in a very similar way to futures. A forward contract is also an agreement to buy or sell an asset at a predetermined price in the future. The profit or loss from the contract will depend on the spot price at the time of contract expiry. Let’s examine some of the key differences between futures and forwards: First, futures contracts are traded on an exchange, whereas forwards are traded OTC (over the counter - meaning two willing parties enter into a contract without going through an exchange). As a result, futures contracts are standardized and more regulated, whereas forward contracts are customizable and less regulated. Forward contracts are generally not available to trade for retail investors (contracts tend to trade between banks and large companies), whereas futures can be traded by almost anyone. Futures also have the added advantage that they can be bought and sold prior to expiry, whereas forwards are more difficult to terminate.


The most fashionable type of derivatives

Options, which are usually exchange traded, are a whole new category of derivatives, and are extremely fashionable among investors. An option contract gives you the right (but not the obligation) to buy or sell a particular asset on a particular date. Call options give you the right to buy, and put options give you the right to sell. For example, today is 1st July, and like before, the spot price of gold is US$1000. A call option that gives the holder the right to purchase gold for US$1000 on 1st October is trading at US$30. As an investor, I believe the price of gold is going to rise over the next three months, so I spend US$30 and purchase this call option. Fast forward to 1st October, and the price of gold is now US$ 1,100. I exercise (use) the option, purchase gold for US$ 1,000, and have made US$ 100 profit (as the current market price is US$ 1,100). My net profit (after subtracting the cost of the option) is US$ 70. If the market price at expiry was below US$ 1000, I would not have exercised the option (as the market price is cheaper than the option strike price) and my profit would be US$ 0. Once we factor in the cost of the option, we have a net loss of US$ 30. The beauty of an option is that if in the example above, gold were to fall, no matter how much it fell, my maximum loss is always US$ 30, the price I paid for the option, whereas my maximum gain is infinite. You can see why options are so popular!

Another over the counter derivatives

Finally, we have swaps. I won’t go into too much detail on swaps because like forwards, they are traded only over the counter, and not available to retail investors. Swaps take all forms such as interest rate swaps, currency swaps, equity swaps and many others. Let’s discuss a basic interest rate swap. Two parties enter into an agreement to swap cash flows based on an agreed notional principal. At regular intervals, one party will pay a fixed amount to another party, while the other party will pay the initial party a floating amount (which varies as interest rates vary). Essentially, interest rate swaps are used by banks and companies to convert fixed liabilities to floating ones and vice versa.

Who bears the risk for derivatives?

There are three types of players in the derivatives markets. These are market makers, hedgers, and investors. Market makers include large banks which buy and sell derivatives to earn spreads and commissions. An example of a hedger would be a commodity producer that uses derivatives to hedge the price for which they can sell their product. Finally, investors use derivatives to profit from market movements and earn return.

A question that people often throw: what is the purpose of investors and speculators in the derivative market? Clearly, market makers are necessary or the market wouldn’t exist. Derivatives are obviously beneficial to hedgers who can better manage their business risks by hedging their exposures. But why do we need speculators? Let’s say a farmer produces corn and has a harvest due in 3 months. If he wants to get rid of the risk he can sell corn futures and lock in a price in 3 months. He has gotten rid of his risk. So where does that risk go? Someone has to take the other side of that contract, and this is where the investor comes in. Investors take on the risks that hedgers want to get rid of. Hedgers pass on the risks to investors, and investors as a result expect to earn a profit for taking on the risk. This why the more investors take part in derivatives markets, the more efficiently they can function and serve the needs of hedgers.

Over the course of this derivatives tutorial, I will focus primarily on futures and options (as this is what is available to retail investors), looking at how they are priced and various trading strategies for each. Next week, we will take a closer look at futures markets; understand how they are priced, how to use them, and how they differ from traditional investments in stocks.
