Options are a type of financial derivative that allows the buyer to have the right, but not the obligation, to buy or sell a specific asset at an agreed price in the future at a specific time. This instrument plays a key role in risk management, investment strategies, and asset allocation. Through options, investors can flexibly respond to market fluctuations, achieve higher investment returns, or hedge risks.

Primitive types

Call Options

A call option gives the buyer the right to buy the underlying asset at an agreed price within a specific time period. If the investor expects the price of the underlying asset to rise, they can buy a call option to lock in a future purchase price.

Put Option

Put options give the buyer the right to sell the underlying asset at a predetermined price within a specific period of time. If the investor anticipates a drop in the price of the underlying asset, they can purchase put options to protect the value of their assets or profit from the price decline.

Key Elements

1. Underlying asset

The underlying asset is the underlying asset involved in the options contract, which can be stocks, indexes, commodities, foreign exchange, etc.

2. Exercise Price

The exercise price is the price at which the option buyer buys or sells the underlying asset when exercising the option.

3. Expiration date

The expiration date is the effective period of the options contract, after which the option will expire.

4. Premium

The premium is the price paid by the buyer to obtain the option, and it is also the income received by the seller.

Main Features and Applications

1. Investment Strategy

Options can be used to implement a variety of investment strategies, such as arbitrage, hedging, and speculation. Investors can flexibly use call options and put options to construct strategies based on market expectations, thereby improving investment returns.

2. Risk Management

Options are an effective risk management tool. By purchasing options, investors can lock in future buying or selling prices, thereby reducing the impact of market volatility on asset value. For example, investors holding stocks can purchase put options to hedge against the risk of stock price decline.

3. Enhanced Profit

Selling options is a common income enhancement strategy, and investors can collect premiums by selling call or put options to increase the cash flow of their investment portfolios.

Advantages and Risks

Advantages

• Flexibility: Options provide a variety of trading strategies that are suitable for different market expectations and investment objectives.
• Leverage effect: Options trading allows investors to control a larger asset value with less capital, improving capital utilization efficiency.
• Risk control: Options can be used to hedge the risks of other investments and reduce the overall risk of the portfolio.

Risk

• Option premium loss: If the option fails to make a profit at expiration, the buyer will lose the entire premium.
• Market Risk: The sharp fluctuations in market prices may lead to rapid changes in the value of options, increasing investment risk.
• Time decay: As the expiration date approaches, the time value of options gradually decreases, which may have a negative impact on the options price.

Common options trading strategies

Successful options traders typically have a variety of trading strategies and can apply them flexibly based on market conditions. Here are several commonly used contract options trading strategies:

1. Bull spread strategy: This is a bullish strategy suitable for moderate market uptrends, through the simultaneous purchase of a call option with a lower strike price and the sale of a call option with a higher strike price. This strategy can reduce costs, but also limits the maximum profit.
2. Bear market spread strategy: This is a bearish strategy, as opposed to a bullish spread, which involves buying a call option with a higher exercise price and selling a call option with a lower exercise price. This strategy is suitable for predicting a moderate decline in the market.
3. Butterfly strategy: This is a neutral strategy that is suitable for situations where the expected market volatility is low. It involves simultaneously buying an option with a lower strike price and an option with a higher strike price, and selling two options with intermediate strike prices. When the market remains stable, this strategy can achieve maximum profit.
4. Straddle Strategy: This is a volatility strategy suitable for markets expected to experience significant volatility but with uncertain direction. By simultaneously buying call options and selling options with the same strike price, this strategy can be profitable when the market sharply rises or falls, but the cost is also relatively high.
5. Calendar Spread Strategy: This strategy involves simultaneously buying and selling options with different expiration dates. For example, selling options with near-term expiration dates while buying options with longer expiration dates, this strategy can profit from the decay of time value.

When using these strategies, it is common to make flexible adjustments based on market conditions and personal risk preferences. For example, when using a bullish spread strategy, if the market rises more than expected, they may consider closing positions early to take profits or adjusting to a more aggressive strategy, while closely monitoring the implied volatility of options and using volatility changes to optimize their trading strategies.

Bitcoin Options Example

Assuming that the investor Xiao Ming expects the price of Bitcoin (BTC) to rise in the next month, and the current spot price of Bitcoin is $25,000. Xiao Ming purchased a call option for Bitcoin with a strike price of $26,000 and an expiration date one month later, paying a premium of $500.

Scenario 1: Bitcoin price rises to $30,000. Xiaoming can buy Bitcoin at a price of $26,000 and sell it at the market price of $30,000, making a profit of $4,000 ($30,000 - $26,000 - $500 = $3,500, net earnings after deducting option premium) .

Scenario 2: With the Bitcoin price staying below $25,000, Xiaoming chooses not to exercise the options and only loses the $500 premium paid.

This example demonstrates the characteristics of options trading, where investors can use options to lock in potential profits while limiting losses within the range of premiums. In assets with significant price fluctuations such as Bitcoin, options become a powerful tool for investors to hedge risks or speculate.
