Options Strategies: Covered Calls & Spreads

Single-leg options trades (buying a call or put) are straightforward but have limitations. Buying options means fighting time decay, and the stock must move significantly to overcome the premium cost. Multi-leg strategies combine two or more options to create specific risk-reward profiles that single options cannot achieve.

Spreads reduce cost and define both maximum risk and maximum reward. Income strategies generate consistent cash flow from time decay. Volatility strategies profit from large moves regardless of direction. The trade-off for these benefits is complexity: each additional leg adds a commission, a bid-ask spread to cross, and another variable to monitor.

Despite this complexity, multi-leg strategies are the backbone of professional options trading because they allow precise expression of market views. You can profit from a stock staying flat, moving within a range, making a large move in either direction, or experiencing a change in implied volatility.

This flexibility is what makes options uniquely powerful compared to simply buying and selling stocks or futures.

The covered call is the most popular options strategy and the entry point for most options beginners who own stock. You buy (or already own) 100 shares of stock and sell one call option against those shares. The premium received is immediate income. If the stock stays below the strike price at expiration, the option expires worthless and you keep the premium plus your shares.

If the stock rises above the strike, your shares are called away (sold) at the strike price, and you keep the premium plus the appreciation up to the strike. If the stock falls, the premium received provides a small buffer against losses. Example: you own 100 shares of Microsoft at $400 and sell a $420 call for $8.00 ($800 income).

Three outcomes: stock stays at $400, you keep $800 income (2 percent return in one month). Stock rises to $430, your shares sell at $420 plus $800 premium for a total $2,800 gain but you miss the move above $420. Stock drops to $380, your $2,000 unrealized loss is partially offset by the $800 premium.

The ideal candidate for covered calls is a stock you own, are moderately bullish on, and would be willing to sell at the strike price.

A vertical spread involves buying and selling options of the same type (both calls or both puts) with the same expiration but different strike prices. A bull call spread buys a lower-strike call and sells a higher-strike call. This reduces cost compared to buying a call alone because the sold call partially offsets the purchased call's premium.

Maximum profit is the difference between strikes minus the net debit paid. Maximum loss is the net debit. Example: stock at $100, buy $100 call for $5, sell $105 call for $3, net cost $2 ($200). Max profit is $5 minus $2 equals $3 ($300). Max loss is $2 ($200). Profit-to-risk ratio is 1.5:1. A bear put spread buys a higher-strike put and sells a lower-strike put, profiting from a decline.

Credit spreads (bull put spread, bear call spread) are the reverse: you collect premium upfront and profit if the stock stays on your side of the short strike. Vertical spreads are ideal when you have a directional opinion but want to reduce cost and define maximum risk. They work particularly well when implied volatility is elevated because you sell expensive premium to offset your purchase.

An iron condor combines a bull put spread below the current price with a bear call spread above it, creating a range within which you profit from time decay. You sell an out-of-the-money put and buy a further-out put (bull put spread for the downside), then sell an out-of-the-money call and buy a further-out call (bear call spread for the upside).

The total credit received is your maximum profit if the stock stays between the two short strikes at expiration. Maximum loss is the width of either spread minus the total credit, occurring if the stock moves beyond either wing. Example: stock at $100, sell $95 put/buy $90 put and sell $105 call/buy $110 call for a total credit of $2 ($200).

Max profit is $200 if the stock expires between $95 and $105. Max loss is $5 spread width minus $2 credit equals $3 ($300) on either side. Iron condors work best in low-volatility, range-bound markets. They are often placed 30 to 45 days before expiration when time decay accelerates. The key risk is a sudden large move that pushes the stock past your short strike, requiring either adjustment or acceptance of the maximum loss.

A straddle involves buying both a call and a put at the same strike price and expiration. You profit when the stock makes a large move in either direction that exceeds the combined premium cost. Example: stock at $100, buy a $100 call for $4 and a $100 put for $4, total cost $8 ($800). Breakevens are $92 and $108.

If the stock moves to $115 or $85, you profit regardless of direction. The straddle is ideal before binary events like earnings, FDA decisions, or court rulings where you expect a big move but are uncertain about direction. The risk is that the stock does not move enough, and you lose the combined premium to time decay.

A strangle is similar but uses out-of-the-money strikes (buy a $105 call and a $95 put), reducing the cost but widening the breakevens and requiring a larger move to profit. Selling straddles and strangles collects premium and profits from stable prices, but carries substantial risk if the stock makes a large move.

These strategies should only be sold by experienced traders who monitor positions actively and have adjustment plans for adverse moves.

Calendar spreads exploit differences in time decay between options with the same strike but different expirations. You sell a near-term option (which decays faster) and buy a longer-term option (which decays slower), profiting from the faster decay of the sold option. Example: sell the 30-day $100 call for $3 and buy the 60-day $100 call for $5, net cost $2.

As days pass, the 30-day option decays faster than the 60-day, potentially allowing you to close the spread at a profit. Calendar spreads work best when the stock stays near the strike price and implied volatility increases. Diagonal spreads are variations that use different strikes in addition to different expirations, creating tilted risk-reward profiles.

For example, buying a longer-dated, slightly in-the-money call and selling a shorter-dated, out-of-the-money call creates a diagonal that benefits from both directional movement and time-decay differential. These are intermediate strategies that require understanding of how time and volatility interact across different expirations.

They are particularly effective in earnings seasons when near-term IV is inflated relative to longer-term IV.
