How covered call works

A covered call is an options strategy where an investor holds a long position in an asset and sells call options on that same asset to generate income.

A covered call involves owning at least 100 shares of a particular stock and simultaneously selling one call option contract for every 100 shares owned. The 'covered' aspect refers to the fact that the investor already owns the underlying shares, which mitigates the risk of unlimited losses if the stock price rises significantly. When a covered call is initiated, the investor receives a premium from the buyer of the call option. This premium is the primary benefit of the strategy, providing immediate income. The sale of the call option contract obligates the seller to sell their shares at the strike price if the option is exercised by the buyer before or at expiration. This effectively caps the potential upside profit on the shares, as any appreciation beyond the strike price will be foregone. The option's premium is influenced by several factors, including the underlying stock's price, the strike price, the time until expiration, and the implied volatility of the stock. Higher implied volatility generally leads to higher option premiums, which is favorable for covered call writers seeking to maximize income. Conversely, lower volatility can result in smaller premiums, making the strategy less attractive in certain market conditions. The investor's profit or loss depends on the stock's movement relative to the original purchase price of the shares and the strike price of the sold call. If the stock price stays below the strike price, the option expires worthless, and the investor keeps the premium and the shares. If the stock price rises above the strike price, the shares are likely to be called away, meaning the investor sells them at the strike price, realizing a profit up to that point plus the received premium. The strategy is often used by investors who are moderately bullish or neutral on a stock and want to generate extra income from their existing holdings.

Why it matters

- A covered call allows investors to generate income from shares they already own. The premium received upfront can enhance returns, especially in sideways or slightly bullish markets.
This strategy can provide a limited hedge against a downturn in the underlying stock's price. The premium received acts as a small buffer, reducing the break-even point for the shares.
Implementing a covered call can limit the overall upside potential of owning the stock. While providing income, it caps the maximum profit an investor can make if the stock's price rises significantly above the strike price.

Common mistakes

- One common mistake is setting the strike price too low, which increases the likelihood of the shares being called away at an undesirable price. To avoid this, choose a strike price that you are comfortable selling your shares at, ideally above your cost basis.
Another error is selling calls on highly volatile stocks without fully understanding the rapid price movements. This can lead to the stock being called away quickly or significant fluctuations in the value of the underlying shares. To mitigate this, consider the historical volatility of the stock and your comfort level with risk.
Investors sometimes fail to consider the tax implications of selling covered calls, as option premiums and potential capital gains on the stock can be taxed differently. It's crucial to consult with a tax advisor to understand how covered call income and sales are treated for tax purposes.
A common oversight is neglecting to monitor the position, especially as expiration approaches or in response to significant news affecting the underlying stock. Active management allows for adjustments, such as rolling the option, to optimize outcomes and avoid unwanted assignments.

FAQs

What happens if the stock price goes above the strike price with a covered call?

If the stock price rises above the strike price at expiration, your shares will likely be 'called away,' meaning you will sell them at the strike price. You will keep the premium received and realize any profit up to the strike price.

Can I lose money implementing a covered call strategy?

Yes, you can still lose money if the underlying stock price falls significantly below your purchase price, even with the premium received. The strategy only provides a limited buffer against downward movement.

How does implied volatility affect the premium of a covered call?

Higher implied volatility generally leads to greater uncertainty about future price movements, resulting in higher premiums for the call options you sell. This can be beneficial for covered call writers seeking more income.
