Option Writer: Definition, Examples & Why It Matters

Snapshot

An Option Writer is an investor who sells options contracts, collecting premiums and assuming the obligation to buy or sell the underlying asset if the option is exercised.

What is Option Writer?

An Option Writer is the seller of an options contract in the financial markets. By writing an option, the investor grants the buyer the right, but not the obligation, to buy (call option) or sell (put option) the underlying asset at a predetermined price within a specified timeframe. In exchange for this granted right, the writer collects an option premium upfront from the buyer. The Option Writer is obligated to fulfill the terms of the contract if the option holder chooses to exercise the option. In finance and wealth management, option writing strategies are utilized for income generation, hedging, or speculative purposes. Writers may engage in covered calls by writing calls on securities they own, thereby generating additional income, or they may sell puts to potentially acquire positions at favorable prices. However, option writing carries risks, especially if the option is exercised and the market moves unfavorably, resulting in potential losses for the writer.

Why Option Writer Matters for Family Offices

Understanding the role of an Option Writer is critical in constructing advanced portfolio strategies and managing risk for investment portfolios. By writing options, wealth managers can supplement income streams through premiums, which is valuable for clients seeking yield enhancement or diversification from traditional long-only positions. However, this activity also requires diligent risk management, since obligations from option writing can expose portfolios to significant downside if the underlying asset's price moves adversely. Tax implications are another important consideration, as premiums received and any resulting gains or losses from option exercises can affect a portfolio’s tax reporting and efficiency. Additionally, proper governance and oversight are necessary to ensure that option writing aligns with the client’s risk tolerance and investment objectives, making it a relevant concept for family offices and advisors managing complex, multi-asset portfolios.

Examples of Option Writer in Practice

Suppose an investor owns 100 shares of a stock priced at $50 and writes a call option with a strike price of $55, expiring in one month, for a premium of $2 per share. The investor collects $200 premium (100 shares x $2). If the stock price stays below $55 until expiration, the option expires worthless, and the investor keeps the premium as income. If the stock rises above $55, the investor may be obligated to sell the shares at $55, potentially missing out on gains above that price but effectively selling the shares at $57 ($55 strike price + $2 premium received).

Option Holder

While the Option Writer is the seller and takes on the obligation of the option contract, the Option Holder is the buyer who has the right to exercise the option but no obligation. The holder pays the premium to the writer and can choose to exercise or let the option expire worthless.

Option Writer FAQs & Misconceptions

What does it mean to be an Option Writer?

An Option Writer sells an option contract and collects the premium upfront, taking on the obligation to sell (in the case of a call) or buy (in the case of a put) the underlying asset if the option is exercised by the buyer.

What risks does an Option Writer face?

The main risk is that the underlying asset’s price moves against the writer’s position, which can result in significant losses if the option is exercised. For example, selling a call on a stock that then rises sharply above the strike price obligates the seller to sell below market value.

How does writing options generate income?

Writing options allows the seller to collect premiums from buyers. If the option expires worthless, the writer keeps the premium as profit, thus generating regular income on their portfolio holdings or cash position.
