Key Takeaways
Calls and puts are the two building blocks of options trading; combining them in specific ways creates strategies that can suit bullish, bearish, or income-focused goals.
A covered call lets you earn income on assets you already hold by selling someone else the right to buy them at a set price.
A married put pairs a long asset position with a put option, capping potential losses while keeping upside open.
Bull call spreads and bear put spreads reduce the upfront cost of directional bets by offsetting one option with the sale of another.
Every strategy carries its own risk profile; understanding that profile before entering a trade is essential.
Introduction
Knowing what a call or put option is and knowing how to use one are two different things. The mechanics of options trading cover the definitions. This article covers the application: four common strategies that traders use to pursue income, protect positions, and make directional bets with defined risk.

What Are Calls and Puts?
A call option gives the holder the right to buy an underlying asset at a fixed price (the strike price) before or on the expiration date. Buyers of calls generally expect the asset price to rise.
A put option gives the holder the right to sell an underlying asset at the strike price before or on expiration. Buyers of puts generally expect the price to fall. Put options are sometimes compared to short selling because both profit when prices decline, though they work differently: short selling requires borrowing the asset, while puts require only paying a premium.
Both calls and puts can be bought or sold. Buying an option gives you the right to exercise it. Selling (writing) an option means you take on the obligation to fulfill the contract if the buyer chooses to exercise it.
Strategies Using Calls and Puts
Covered calls
A covered call involves holding an underlying asset (such as a stock or cryptocurrency) and selling a call option on that same asset. The word "covered" means the option writer already owns the asset, so they can deliver it if the buyer exercises the contract.
How it works:
You own 100 shares of a stock currently trading at $50.
You sell a call option with a strike price of $55 expiring in one month and collect a $2 premium per share ($200 total).
If the stock stays below $55 by expiration, the call expires worthless and you keep the $200 premium.
If the stock rises above $55, the buyer may exercise the call. You sell your shares at $55 but keep the $200 premium, capping your upside at $700 on a $5,000 position.
Covered calls are typically used when a trader expects the asset price to remain flat or rise only modestly. The strategy generates income from the premium but limits gains if the price surges past the strike.
Married put
A married put combines a long position in an underlying asset with the purchase of a put option on that same asset. It functions as a form of insurance: the put sets a floor on potential losses without limiting how much the position can gain.
How it works:
You buy 100 shares of a stock at $50 per share.
At the same time, you buy a put option with a $48 strike price expiring in two months, paying a $1.50 premium per share ($150 total).
If the stock falls to $40, you can exercise the put and sell your shares at $48, limiting your loss to $350 (the $2 drop to the strike plus the $150 premium) instead of the $1,000 loss you would have taken without the put.
If the stock rises to $60, your gain is $1,000 on the shares minus the $150 premium cost, coming to a total of $850.
This strategy suits traders who want to hold a position through a potentially volatile period without accepting unlimited downside risk. The cost is the premium paid for the put.
Bull call spread
A bull call spread involves buying a call option at a lower strike price and simultaneously selling a call option at a higher strike price on the same asset and expiration date. The premium received from selling the higher-strike call offsets part of the cost of buying the lower-strike call.
How it works:
A stock trades at $100.
You buy a call with a $100 strike price for a $5 premium and sell a call with a $110 strike price for a $2 premium, for a net cost of $3 per share ($300 total).
If the stock closes at $110 or above at expiration, your maximum gain is $700 (the $10 spread minus the $3 net premium paid).
If the stock closes at or below $100, both options expire worthless and your maximum loss is the $300 net premium.
The bull call spread reduces the upfront cost of a bullish bet but caps the potential profit. It makes sense when a trader expects a moderate, not dramatic, price increase.
Bear put spread
A bear put spread mirrors the bull call spread but uses put options to profit from a falling price. You buy a put at a higher strike price and sell a put at a lower strike price on the same asset and expiration.
How it works:
A stock trades at $100.
You buy a put with a $100 strike price for a $5 premium and sell a put with a $90 strike price for a $2 premium, for a net cost of $3 per share ($300 total).
If the stock falls to $90 or below at expiration, your maximum gain is $700 (the $10 spread minus the $3 net premium).
If the stock stays at or above $100, both options expire worthless and your maximum loss is the $300 net premium.
Like the bull call spread, the bear put spread lowers cost at the expense of capped profit. It is suited to traders who expect a moderate decline rather than a sharp drop.
Considerations in Options Trading
Options strategies can offer defined risk, income generation, and flexibility that outright buying or selling an asset cannot match. Good risk management starts with understanding the specific risk profile of each strategy before entering a trade.
Time
One of the most important factors affecting options is time decay. An option loses value as it approaches expiration, all else equal. This is captured by the Greek letter theta. For buyers of options, time decay works against you. For sellers, it can work in your favor. Similarly, changes in market volatility affect option prices through vega. A rise in implied volatility tends to increase option premiums; a fall tends to reduce them. Understanding how both forces interact with your position is important. For a deeper dive, you can also explore the full range of option Greeks.
Execution
Directional strategies like bull call spreads and bear put spreads limit maximum loss to the premium paid. Multi-leg strategies, though, require careful execution: both legs must be entered and managed correctly, and commissions apply to each. Timing also matters. Options strategies often depend on both price direction and timing being correct. Even a trader who accurately predicts a direction may lose money if the move happens after the option expires. Pairing options strategies with technical analysis can help with entry and exit timing, though no approach removes uncertainty entirely.
Risk
Selling options, as in the covered call, creates income but introduces an obligation. If the underlying asset moves sharply against the position, the seller bears that risk. Covered calls are considered lower-risk because the position is "covered" by the existing asset holding. Naked short options (selling without owning the underlying or a hedging option) carry substantially higher risk and are generally not suitable for inexperienced traders.
FAQ
When should you use a covered call instead of just holding an asset?
A covered call can be appropriate when you already own an asset and expect its price to remain roughly flat or rise only modestly over a set period. By selling a call option, you collect a premium that adds to your total return. The trade-off is that your upside is capped at the strike price if the asset rises sharply. Traders typically use covered calls repeatedly on the same position, collecting premiums regularly in a relatively stable or sideways market.
What is the maximum loss on a married put strategy?
The maximum loss on a married put is limited to the difference between the purchase price of the asset and the put strike price, plus the premium paid for the put. For example, if you buy a stock at $50 and a put with a $48 strike for a $1.50 premium, your maximum loss per share is $3.50 ($2 drop to strike + $1.50 premium). Your upside on the stock position remains fully open, reduced only by the premium cost.
How are bull call spreads and bear put spreads different from buying a single option?
A single long call or long put gives you potentially greater profit if the price moves significantly in your favor, but it also costs more in premium. A spread involves buying one option and selling another, which reduces your net premium outlay and therefore your maximum loss. The trade-off is that profit is also capped. Spreads are generally preferred when a trader expects a moderate price move rather than a large one.
Are these strategies suitable for beginner traders?
Options strategies involve more moving parts than simply buying or selling an asset. Covered calls and married puts are generally considered more accessible entry points because they build on a position you already hold. Bull call spreads and bear put spreads require managing two option legs simultaneously. Before using any options strategy, it's worth developing a solid understanding of how options are priced and how time and volatility affect that pricing.
Can these strategies be applied to cryptocurrency options?
Yes. The same structural logic applies to crypto options as to stock options. However, cryptocurrency markets tend to exhibit higher volatility, which affects option premiums and the potential speed of price movements. Wider price swings can work for or against a strategy depending on whether you are a net buyer or net seller of options. Checking current platform documentation for contract specifications, expiration cycles, and settlement methods is advisable before trading.
Closing Thoughts
Calls and puts become most useful when applied within a defined strategy rather than in isolation. The strategies covered in this article share a common characteristic: the maximum loss is known before the trade is entered, which is one of the features that draws traders to options over outright directional bets.
