Abstract
Options are a derivative financial instrument used to create an exposure to a particular underlying asset, either in the form of a Call Options that gives the holder the right to buy at a certain date and price, or in the form of a Put Option that gives the holder the right to sell at a certain date and price. Options are often used to speculate on the future direction of the underlying asset or to hedge against losses in the underlying asset. In this paper, the key features of options and the drivers of option pricing are examined. The paper concludes by considering the roles of options in the financial markets.

Introduction
Options are financial contracts that give their holders the right to buy or sell a certain asset at a predetermined price on or before a future date. The asset underlying the option can be stocks, commodities, currencies, bonds, indexes, and many other financial instruments. Options are unique among derivative instruments because they represent the right, but not the obligation, to purchase or sell the underlying asset. In other words, the owner of a call option has the right to buy the underlying asset, while the owner of a put option has the right to sell it.
Options are used both to speculate on the future direction of the underlying asset and to manage risk. Speculators would typically use options to bet on the direction of the asset’s price in the future. For instance, an investor expecting a stock price to increase in the next few months could buy call options on that stock. If their expectations were met and the stock price increased, the option would expire in the money and the investor would reap a profit. On the other hand, if the stock price decreased, the option would expire out of the money and the investor would suffer a loss, but the amount of the loss would be limited to the amount initially paid for the option. Thus, options can help investors to limit the amount of risk they face when speculating on the future direction of the underlying asset.
On the other hand, risk management is the process of minimizing potential losses. Risk management is built on the expectation that the investor possesses information to assess the probability of a given event or outcome taking place or of a given asset’s price moving in a desired direction. This information can be used to craft hedging strategies that involve taking opposite positions in the asset and an option that corresponds with that position. This is known as a spreads strategy, and it allows the investor to limit the amount of risk they are exposed to in case the asset’s price moves in the opposite direction of their expectations.
Option Pricing
The dynamics of option pricing can be quite complex, but in general the price of an option is set such that it reflects three variables: the current price of the underlying asset, the level of volatility implied by the underlying asset, and the amount of time until the option expires. This is known as the Black-Scholes option pricing model, which is still in widespread use today.
The current price of the underlying asset is the first factor that affects the price of an option. If the underlying asset’s price increases, the price of the option increases as well. Likewise, if the underlying asset’s price decreases, the option’s price decreases too.
The volatility of the underlying asset is the second factor that affects the price of an option, and it is generally determined by looking at the asset’s historical price movements. Volatility is the measure of the expected price fluctuation in the asset’s price based on its past performance. The higher the volatility of the underlying asset, the higher the price of the option will be.
Finally, the amount of time until the option expires affects the option’s price as well. If the option’s expiration date is farther away, the option will be more expensive than if it were set to expire sooner. This is because the longer the investor can hold the option, the more likely it is for the price of the underlying asset to move in favor of the option’s position.
Conclusion
Options are an important tool for both speculators and risk managers in the financial markets, and their dynamics and pricing are heavily influenced by the price of the underlying asset, the level of volatility, and the remaining time before the option expires. By understanding these factors and how they interact, investors can use options to their advantage and tailor their investments to their desired objectives.
