Options trading is a type of financial instrument that has a long history dating back to the ancient Greeks and Romans. The concept of options trading can be traced back to the early days of commerce, where merchants would use options contracts to hedge against the risk of crop failures or other uncertainties.
In the modern era, options trading began to be used as a financial instrument in the early 1800s. The first standardized options contract was traded on the Chicago Board of Options Exchange (CBOE) in 1973. Since then, options trading has become a popular and widely used form of investment.
Options trading allows investors to buy or sell the right to buy or sell a specific asset at a specific price, called the strike price, at a specific time in the future. This is known as a call option or a put option.
A call option is the right to buy an asset at a specific price, while a put option is the right to sell an asset at a specific price. The price of an option is called the premium.
When trading options, investors use a variety of strategies, such as buying options to make a profit when the price of the underlying asset rises, or selling options to make a profit when the price of the underlying asset falls.
One of the most important concepts in options trading is the Greeks. The Greeks are a set of metrics that measure the sensitivity of the option’s value to changes in various factors such as the underlying asset price, time to expiration, and volatility. The most common Greeks are delta, gamma, theta, and vega.
Delta measures how much the price of the option changes for each $1 change in the price of the underlying asset. A delta of 0.5 means that if the underlying asset price increases by $1, the option price will increase by $0.50.
Gamma measures how much the delta of an option changes for each $1 change in the price of the underlying asset. A high gamma means that the delta of the option changes quickly when the underlying asset price changes.
Theta measures how much the price of the option changes for each day that passes. A theta of -0.02 means that the option price will decrease by $0.02 for each day that passes.
Vega measures how much the price of the option changes for each 1% change in volatility. A vega of 0.2 means that if the volatility of the underlying asset increases by 1%, the option price will increase by $0.2.
Another important concept in options trading is implied volatility. Implied volatility is a measure of the expected volatility of the underlying asset, and it is used to calculate the theoretical value of an option. The higher the implied volatility, the higher the premium of the option will be.
Options trading can also be used for hedging. Hedging is a risk management strategy that is used to reduce the potential loss from an investment. For example, if an investor owns a stock that they believe will decrease in value, they can buy a put option as a hedge against the potential loss.
Options trading can also be used for speculation. Speculation is the act of buying an option with the expectation of making a profit from the price movement of the underlying asset. Speculators can use a variety of strategies to make a profit, such as buying call options when they expect the price of the underlying asset to rise or buying put options when they expect the price of the underlying asset to fall.
