Covered Call
Key Takeaways
- A covered call sells a call option against 100 shares you already own
- It generates income from the option premium but caps upside potential
- One of the most conservative and popular options strategies
- Best suited for neutral to slightly bullish market outlooks
Definition
A covered call is an options strategy in which an investor who owns (or buys) shares of a stock simultaneously sells (writes) a call option on those same shares. The call sold is "covered" because the investor already owns the underlying shares, eliminating the need to buy them at the market price if the option is exercised.
The primary purpose of a covered call is to generate additional income on an existing stock position through the option premium received. In exchange for this income, the investor agrees to sell their shares at the strike price if the stock rises above it, capping their upside potential.
Covered calls are one of the most popular options strategies because they are relatively simple, conservative, and can be used in most brokerage accounts, including some IRAs. They work best when the investor has a neutral to slightly bullish outlook — expecting the stock to stay flat or rise modestly.
How It Works
The covered call strategy involves: 1) Own 100 shares of a stock (or buy them). 2) Sell one call option against those shares, typically with a strike price above the current stock price and an expiration 30-45 days out. 3) Collect the option premium. 4) If the stock stays below the strike at expiration, the option expires worthless and you keep the shares plus the premium. 5) If the stock rises above the strike, your shares are called away (sold) at the strike price, and you keep the premium plus any appreciation up to the strike.
Maximum profit = (Strike Price - Stock Purchase Price + Premium) × 100. Maximum loss = (Stock Purchase Price - Premium) × 100 (if stock goes to zero). The breakeven is the stock purchase price minus the premium received.
Many investors sell covered calls repeatedly (month after month) on their long-term stock holdings, generating steady income that can add 5-15% annually to their total return. This strategy works best on stocks with moderate volatility that trade in a range.
Example
An investor owns 100 shares of Intel (INTC) purchased at $32 per share. With Intel trading at $33, they sell a call option with a $36 strike price expiring in 35 days for $0.80 per share ($80 per contract). Three outcomes: 1) Intel stays below $36: the option expires worthless, the investor keeps the $80 and still owns the shares. They can sell another covered call. 2) Intel rises to $40: shares are called away at $36. Total profit = ($36 - $32 + $0.80) × 100 = $480. They miss the move from $36 to $40 ($400 in forgone profit). 3) Intel drops to $28: the option expires worthless ($80 gain), but the stock position loses $500. Net loss is $420 instead of $500 — the premium provided a small cushion.
Why It Matters
Covered calls are a practical strategy for income-oriented investors and retirees seeking to enhance the yield on their stock portfolios. In a low-interest-rate environment, the ability to generate 5-10% additional annual income from stock positions is particularly valuable.
The strategy also introduces investors to options in a low-risk way. Because the call is covered by owned shares, there is no risk of catastrophic loss from the options position itself. This makes it an excellent starting point for learning options trading before progressing to more complex strategies.
