Option Buying and Option Selling

 

Understanding Option Buying and Option Selling

Options are financial derivatives that give traders the right, but not the obligation, to buy or sell an underlying asset at a predetermined price before a certain expiry date. Options are widely used in stock markets, commodities, indices, and currencies. There are two main types of options — Call Options and Put Options. And two basic ways to trade options — buying options and selling options.

What is Option Buying?

Option buying means purchasing a call or put option contract, paying a premium upfront to gain the right to trade the underlying asset later.

• Call Option Buying: When you buy a call option, you get the right to buy the underlying asset at the strike price before expiration. Traders buy calls if they expect the price of the asset to rise.

• Put Option Buying: When you buy a put option, you get the right to sell the underlying asset at the strike price before expiration. Traders buy puts if they expect the price of the asset to fall.

Benefits of Option Buying:

1. Limited Risk: The maximum loss is limited to the premium paid for the option.

2. Leverage: Buyers control a larger amount of the asset with a small investment.

3. Flexibility: Options can be used to profit from bullish or bearish market views.

4. No Obligation: Buyers are not obligated to execute the trade; they can let the option expire worthless if it’s not profitable.

Risks of Option Buying:

• The premium paid may expire worthless if the market does not move as expected.

• Options have expiration dates, so timing is crucial.

• Option buyers can lose 100% of their invested premium.

What is Option Selling?

Option selling (also called option writing) means selling call or put options and collecting the premium upfront. Here, the seller takes on an obligation:

• Call Option Selling: The seller agrees to sell the underlying asset at the strike price if the buyer exercises the option.

• Put Option Selling: The seller agrees to buy the underlying asset at the strike price if the buyer exercises the option.

Why Sell Options?

Option sellers earn the premium paid by buyers, which can be a source of steady income if done correctly.

Types of Option Sellers:

• Covered Call Seller: Owns the underlying asset and sells call options on it.

• Naked Option Seller: Sells options without owning the underlying asset, which is riskier.

Benefits of Option Selling:

1. Income Generation: Sellers receive premium income upfront.

2. Higher Probability of Profit: Many options expire worthless, so sellers can profit from time decay.

3. Can Use as Hedging: Selling options can be part of complex strategies to reduce risk.

Risks of Option Selling:

• Unlimited Losses for Call Sellers: If the underlying price rises sharply, call sellers may have to sell at a lower price, leading to big losses.

• Large Losses for Put Sellers: If the price falls sharply, put sellers may have to buy the asset at above market value.

• Margin Requirements: Sellers must maintain margin and can face margin calls if the market moves against them.

Key Differences Between Option Buying and Option Selling

Aspect	Option Buying	Option Selling
Risk	Limited to premium paid	Potentially unlimited or large
Reward	Potentially large (unlimited for calls, significant for puts)	Limited to premium received
Obligation	No obligation to execute	Obligation to fulfill if exercised
Cost	Pay premium upfront	Receive premium upfront
Market View	Buy calls for bullish, buy puts for bearish	Sell calls for neutral/bearish, sell puts for neutral/bullish
Time Decay	Negative impact (value decreases over time)	Positive impact (time decay works in favor)

Practical Example

Imagine stock XYZ is trading at $100.

• Option Buying: You buy a call option with a strike price of $105, paying a premium of $2. If the stock price rises to $110 before expiration, you can exercise your option to buy at $105, making a $5 profit per share minus the $2 premium (net $3). If the stock stays below $105, your loss is limited to $2 premium.

• Option Selling: You sell a call option with a strike price of $105 and receive a $2 premium. If the stock price stays below $105, the option expires worthless and you keep the $2 premium. But if the stock rises to $110, you may have to sell at $105, losing $5 per share minus the $2 premium, resulting in a $3 loss.

When to Use Option Buying or Selling?

• Option Buying is suitable when you expect strong market moves and want to limit your risk. It is often used for speculation or hedging.

• Option Selling is used when you expect the market to stay neutral or move slowly. It suits traders looking for income from premiums but who are ready to accept the risk or hedge it with other positions.

Conclusion

Option buying and option selling are two sides of the same coin in options trading. Buying options offers limited risk with potentially high rewards, while selling options provides steady income with higher risk exposure. Both strategies require a clear understanding of the market, the underlying asset, and risk management techniques.

Beginners should start with option buying to limit losses before exploring the complexities and risks of option selling. With practice and knowledge, traders can combine both methods to build robust trading strategies.
