Caps vs Floors: What's the Difference?

When it comes to managing risk in the financial markets, there are a variety of strategies that investors and traders can employ. Two of the most common approaches are known as "caps" and "floors." While both strategies involve the use of derivatives, there are some key differences that should be understood before employing either strategy.

What is a Cap?

A "cap" is a type of derivative that gives the holder the right, but not the obligation, to buy a underlying asset at a predetermined price (the "cap price") on or before a specified date (the "expiration date"). The underlying asset in a cap can be anything from a stock or commodity to a currency or interest rate. For example, let's say that an investor is concerned about a potential decline in the price of XYZ stock over the next six months. The investor could purchase a six-month XYZ stock price cap with a strike price of $50. If the price of XYZ stock falls below $50 at any point over the next six months, the investor can exercise the option and buy the stock at $50, regardless of the actual market price. If the price of XYZ stock never falls below $50, the investor simply lets the option expire worthless.

What is a Floor?

A "floor" is the opposite of a cap. It is a type of derivative that gives the holder the right, but not the obligation, to sell a underlying asset at a predetermined price (the "floor price") on or before a specified date (the "expiration date"). As with a cap, the underlying asset in a floor can be anything from a stock or commodity to a currency or interest rate. For example, let's say that an investor is concerned about a potential increase in the price of XYZ stock over the next six months. The investor could purchase a six-month XYZ stock price floor with a strike price of $50. If the price of XYZ stock rises above $50 at any point over the next six months, the investor can exercise the option and sell the stock at $50, regardless of the actual market price. If the price of XYZ stock never rises above $50, the investor simply lets the option expire worthless.

Key Differences

While both caps and floors are used to manage risk, there are some key differences between the two strategies. First, a cap is used to protect against a potential increase in the price of the underlying asset, while a floor is used to protect against a potential decline in the price of the underlying asset. Second, a cap gives the holder the right to buy the underlying asset at a predetermined price, while a floor gives the holder the right to sell the underlying asset at a predetermined price. Finally, the expiration date for a cap is typically before the expiration date for a floor. This is because a cap is used to protect against a potential price increase, while a floor is used to protect against a potential price decline.

Pricing

The price of a cap or floor is determined by a number of factors, including the current price of the underlying asset, the strike price of the option, the expiration date of the option, the volatility of the underlying asset, and the interest rate. The higher the current price of the underlying asset, the higher the price of the option. The higher the strike price of the option, the lower the price of the option. The closer the expiration date of the option, the higher the price of the option. The higher the volatility of the underlying asset, the higher the price of the option. The higher the interest rate, the lower the price of the option.

Risks

There are a number of risks associated with both caps and floors. First, both options are subject to time decay. This means that the longer the option is held, the more the option will lose value. Second, both options are subject to the risk of the underlying asset. This means that if the price of the underlying asset moves in the opposite direction of what the investor is expecting, the option will lose value. Finally, both options are subject to the risk of interest rates. This means that if interest rates rise, the value of the option will decline. For this reason, it is important to carefully consider all of the risks before employing either strategy.

Conclusion

Caps and floors are two of the most common strategies used to manage risk in the financial markets. Both options are subject to time decay, the risk of the underlying asset, and the risk of interest rates. However, there are some key differences between the two strategies. First, a cap is used to protect against a potential increase in the price of the underlying asset, while a floor is used to protect against a potential decline in the price of the underlying asset. Second, a cap gives the holder the right to buy the underlying asset at a predetermined price, while a floor gives the holder the right to sell the underlying asset at a predetermined price. Finally, the expiration date for a cap is typically before the expiration date for a floor. This is because a cap is used to protect against a potential price increase, while a floor is used to protect against a potential price decline.
