Covered Call
A covered call is an options strategy where a participant who holds shares of a stock writes (sells) a call option on the same stock, collecting the premium as income. In India, this strategy is applicable to F&O-eligible stocks where both the underlying shares and exchange-traded call options are available.
The covered call is considered one of the most conservative options strategies because the written call is backed by the underlying shares, eliminating the open-ended risk that an uncovered (naked) call writer would face. The maximum profit from the strategy is capped at the strike price minus the purchase price of the shares, plus the premium received. The maximum loss is the full cost of the shares minus the premium collected.
In the Indian context, covered calls were discussed primarily in the context of large-cap F&O-eligible stocks such as Reliance Industries, HDFC Bank, Infosys, and TCS. An investor holding these shares might write slightly out-of-the-money call options at each monthly expiry to generate additional income. If the share price remained below the strike, the option expired worthless and the full premium was retained. If the share price rose above the strike, the investor faced the opportunity cost of capped participation in the upside.
The break-even for a covered call is the purchase price of the underlying shares minus the premium received. If the shares were purchased at ₹1,000 and a call was written for a premium of ₹30, the effective break-even fell to ₹970. This modest buffer provides limited downside protection but does not constitute a meaningful hedge against large adverse moves in the underlying.
A misconception is that covered call writing is risk-free income. The primary risk is that the underlying shares decline significantly — a drop far exceeding the premium received. The covered call writer retains full downside exposure to the underlying. Additionally, in a strongly rising market, the capped upside of the covered call can result in substantial opportunity cost relative to simply holding the shares.
Covered calls are most commonly discussed as income-enhancing strategies in sideways or mildly bullish markets, where the underlying is not expected to appreciate strongly. In trending bull markets, the capped upside makes them less attractive from a total return perspective.
