Covered Calls in a Bear Market: Defensive Strategy 2026

Why covered calls in a bear market require a different approach

Covered calls in a bear market face a structural problem: the strategy is designed for flat-to-moderately-bullish markets, not for sustained declines. When a stock falls 20, 30, or 40 percent, the call premium collected each month shrinks in absolute dollar terms because the stock price is lower, and the premium's cushion against further decline becomes proportionally smaller. The mathematical reality is that no reasonable covered call premium can protect against a major drawdown.

The Cboe BuyWrite Index (BXM), which tracks a systematic covered call strategy on the S&P 500, illustrates this pattern. In moderate declines, BXM outperforms the underlying index because the premium income offsets small losses. In severe declines, BXM still falls substantially because the premium is only a fraction of the index loss. The premium provides a cushion, not a floor.

The math of declining premium in a declining market

Consider a stock purchased at US$100. In the first month, a US$105 call at 0.28 delta might pay US$2.50. The stock drops to US$88. The same 0.28 delta call at US$92 now pays roughly US$2.00 because the underlying is cheaper and the absolute strike is lower. After another decline to US$75, a US$78 call might pay US$1.50. Over three months, the writer collected US$6.00 in total premium against a US$25 stock decline -- the premium covered 24 percent of the loss.

Compare this to simply selling the stock at US$95 (after the first US$5 decline). The loss would be US$5 versus the US$19 net loss from holding through three months of covered call writing. The point is not that selling is always correct -- it is that the covered call does not transform a bear-market stock into a safe income position.

Defensive adjustments: ITM strikes, collars, and exits

In-the-money covered calls provide a larger premium and a higher probability of being called away. In a bear market, this can serve as a structured exit: you are agreeing to sell at the strike price and keeping the ITM premium as a larger cushion. For example, selling a US$72 call when the stock is at US$75 might pay US$5, providing a US$70 breakeven and a defined exit at US$72 if the stock stabilizes or recovers slightly.

A collar (buying a put at a lower strike and selling a call at a higher strike) provides hard downside protection at the cost of capped upside. The put premium is often expensive during high-volatility bear markets, but the call premium offsets part of the cost. A zero-cost collar where the call premium fully pays for the put gives a defined range with no additional capital outlay.

The cleanest defensive action is sometimes the simplest: sell part or all of the position. If the investment thesis that justified owning the stock is no longer valid, no amount of covered call premium repairs a broken thesis. Selling realizes a loss that may be tax-deductible (subject to wash-sale rules) and frees capital for a position with a better risk-reward profile.

The rolling-down trap and how to avoid it

Rolling down means closing the current short call and simultaneously writing a new call at a lower strike. Each roll may generate a small net credit, but the cumulative effect is that the writer has agreed to sell the stock at progressively lower prices. After rolling down from US$105 to US$92 to US$78, assignment means selling at US$78 -- locking in a US$22 per-share loss from the US$100 cost basis, partially offset by cumulative premium.

The psychological trap is that each individual roll feels like a rational trade: collect a small credit, extend the time, and hope for a bounce. But the sequence of rolls represents a gradual acceptance of a lower and lower exit price without ever making the active decision to sell. A better approach is to define a minimum acceptable strike before the first roll. If the stock reaches a price where the covered call strike would be below your loss threshold, stop rolling and choose between holding the stock without a call, adding a protective put, or selling.

When to stop writing covered calls entirely

The hardest decision in a bear market is not what to do -- it is when to admit that the original position has changed from an investment into a hope. Covered calls do not convert hope into strategy. They can reduce cost basis incrementally in mild declines, but in severe declines they are a thin blanket on a cold night. Making the stop-writing rule before the market tests you is always better than making it during the decline.

• The stock has fallen more than 30 percent from your cost basis and the thesis that supported ownership is no longer intact.
• The monthly premium at your preferred delta is less than 1 percent of the current stock value, making the risk-reward unfavorable.
• You find yourself writing calls only to avoid the psychological discomfort of watching a losing position without doing anything.
• The stock is approaching a level where you would buy it fresh in a new portfolio -- meaning the loss is already realized in economic terms and the call is merely delaying the decision.
• A collar or protective put offers a better risk-reward tradeoff than the uncapped downside of continued stock ownership with only a small premium cushion.
