Covered Calls and Cash-Secured Puts: How They Work and What a Funded Account Supports in 2026

Covered calls and cash-secured puts are the two option strategies most investors meet first. Both involve selling an option, collecting a premium, and accepting an obligation in return. A covered call trades away some of a stock's upside for income. A cash-secured put gets paid to wait for a lower purchase price. They are often described as conservative, and compared with selling options with nothing behind them, they are.

They are also built for a particular kind of account: one that holds shares, holds positions for days or weeks, and is ready for the option to be assigned. That is not what a day-trading funded options account looks like. If you trade options intraday, it is worth understanding these strategies properly, both because their payoff logic shows up everywhere in options and because you need to know exactly which parts carry over to your account and which do not.

In this guide we'll cover what covered calls and cash-secured puts are, how their payoffs work with worked numbers, why assignment is central to both, how strike and expiration choices shape the trade, and what a TradeFundrr options account supports, including the defined-risk structures that teach the same skills inside an intraday, simulated environment.

Key Takeaways

• Know the trade-off. A covered call caps your upside in exchange for premium; a cash-secured put gives you premium in exchange for agreeing to buy lower.
• Respect the downside. Both strategies keep most of a stock owner's downside. The premium cushions a fall; it does not prevent one.
• Treat assignment as the plan. These strategies only make sense if you are happy to sell the shares at the call strike, or buy them at the put strike.
• Know what your account supports. TradeFundrr options accounts trade calls and puts, not shares, and are intraday only, so a classic covered call cannot be built there.
• Practice the payoff with defined risk. Credit spreads and other supported structures let you work on premium, strikes and risk inside written limits.

What are covered calls and cash-secured puts?

A covered call is a short call written against shares you already own, usually 100 shares per contract. A cash-secured put is a short put written while you set aside enough cash to buy the shares if you are assigned. In both, you collect a premium up front and take on an obligation to sell or buy the stock at the strike price.

The covered call

The Options Industry Council describes the covered call as writing a call that is covered by an equivalent long stock position. The investor earns premium income and gets a small hedge on the stock, in return for forfeiting much of the stock's upside for as long as the short call is open. If the stock rallies above the strike, the shares are increasingly likely to be called away.

When the shares and the call are opened at the same time, the trade is often called a buy-write. When the call is written against shares already in the portfolio, it is a covered call in the narrow sense. The analysis is the same either way.

The cash-secured put

The cash-secured put, in OIC's description, involves writing an at-the-money or out-of-the-money put and setting aside enough cash to buy the stock. OIC calls it primarily a stock acquisition strategy for a price-sensitive investor. The goal is to be assigned and acquire the stock below today's market price, with the premium lowering the effective purchase price further.

The "cash-secured" part is what separates it from a naked put. A naked put writer hopes the put loses value and can be closed early at a profit. A cash-secured put writer has the money ready and wants the shares if the price comes down. Same option, very different intention.

How do covered call and cash-secured put payoffs work?

Both strategies have limited upside and substantial downside, and at expiration their payoff shapes look almost the same: a line that rises with the stock and then goes flat. The covered call goes flat at the call strike. The cash-secured put is flat above the put strike and falls below it.

A covered call with numbers

Illustrative example: you own 100 shares of a stock bought at $50. You write one $55 call expiring in about a month and collect $1.50 per share, or $150. Here is what can happen at expiration.

• The stock finishes below $55. The call expires worthless, you keep the $150 and the shares.
• The stock finishes above $55. The call is likely assigned. You sell the shares at $55 and keep the premium, for a total gain of $650: $5 per share on the stock plus $1.50 in premium.
• The stock falls. The $150 premium offsets the first $1.50 per share of the decline, so your breakeven is $48.50. Below that, you lose dollar for dollar like any stock owner.

OIC's formulas match this: maximum gain is the strike minus the stock purchase price plus the premium received, and maximum loss is the stock purchase price minus the premium received, which OIC labels substantial. The worst case is the stock going to zero.

A cash-secured put with numbers

Illustrative example: the same stock trades at $50. You write one $45 put and collect $1.20 per share, or $120, while setting aside $4,500 in cash to cover a possible assignment.

• The stock stays above $45. The put expires worthless and you keep the $120.
• The stock finishes below $45. The put is likely assigned. You buy 100 shares at $45, and the effective purchase price is $43.80 after the premium.
• The stock collapses. You are still obligated to buy at $45. The maximum loss is the strike minus the premium, $4,380, if the stock goes to zero.

OIC notes the honest tension here: the premium is comparatively small compensation for accepting the large downside risk of a stock owner. It also points out that the maximum loss is lower than buying the stock outright at today's price, because you bought lower and kept the premium.

Neither strategy removes stock risk. Each trades part of the upside for premium, and each only makes sense for someone happy to own or sell the shares at the strike.

Why the two payoffs look alike

Look at the two charts and the resemblance is not an accident. Owning shares and selling a call produces, at expiration, the same shape as selling a put at the same strike and holding cash. Options traders lean on this relationship constantly: different combinations of stock, calls, puts and cash can produce the same payoff. Understanding it is one of the most useful things a beginner can learn, because it lets you see that two strategies with very different names can be the same bet.

Why is assignment central to both strategies?

Because the strategies are built around it. A covered call writer sets an exit price, the strike plus premium, and assignment means that price was reached. A cash-secured put writer sets an entry price, the strike minus premium, and assignment means the shares were bought there. If you would hate either outcome, the strategy is not for you.

How OIC frames it

OIC is direct on this point. It says the possibility of assignment is central to the covered call, so the strategy makes more sense for investors who view assignment as a positive outcome, and that the best candidates are stock owners who are perfectly willing to sell. It adds that the only sure way to avoid assignment is to close the position, which can cost extra if the stock is climbing fast. For the cash-secured put, it says the writer actually wants to acquire the stock via assignment.

That framing is the honest version of "income strategy." The premium is real, but it is payment for taking on an obligation. Traders who sell covered calls on a stock they secretly want to keep, or sell puts on a stock they would never want to own at the strike, are collecting premium for a risk they have not accepted.

Assignment is a live-market event

Assignment, exercise and the delivery of shares only happen when a real option contract is traded against a real counterparty and settled through the clearing system. In a live brokerage account, a short call can be assigned and your shares delivered; a short put can be assigned and shares put into your account with cash going the other way. Our guide to assignment risk for funded options covers how this works in more detail.

None of that happens in a TradeFundrr account, because the account is simulated and no real trade is executed. There is no counterparty to exercise against you and no shares to deliver. The account is also intraday only, so positions are closed within the session rather than carried toward expiration. What does carry over is the skill: knowing where your obligation sits, what it would cost to close a short option that has moved against you, and how premium changes as the stock approaches the strike. Those are live-ready skills, and they matter in any account.

How do you choose strikes and expirations?

Strike choice is a trade-off between premium and room. A strike closer to the current price pays more premium but leaves less upside on a covered call, or a higher chance of being assigned on a put. A strike further away pays less but leaves more room. Expiration choice decides how much time value you are selling and how long you carry the obligation.

Strike: premium versus room

For a covered call, OIC notes that choosing a higher, out-of-the-money strike preserves more of the stock's upside, but generates less premium and therefore a smaller cushion if the stock falls. Whatever the choice, it says the strike plus premium should be an acceptable liquidation price. That is a useful test: if you would be upset to sell at that price, pick a different strike or do not write the call.

For a cash-secured put, the same logic runs in reverse. The strike minus the premium should be a price at which you would genuinely be glad to own the stock, no matter how low the market goes afterward. OIC is explicit that the investor must be comfortable with the strike as an acceptable long-term purchase price.

Expiration: time value and how long you are exposed

Option sellers are paid largely for time value, which erodes as expiration approaches. That decay accrues over days and weeks, and it speeds up near expiration. A longer-dated option pays more premium in dollars but ties you to the obligation for longer. A shorter-dated option pays less, decays faster and gives you more frequent decisions. Our guide to theta decay for day trading options explains how that decay looks inside a single session, where it is a much smaller slice than most beginners expect.

Implied volatility matters too. Higher implied volatility raises option premiums, which makes selling look more attractive, but it is high for a reason: the market expects larger moves. A fat premium on a stock heading into earnings is compensation for real risk, not free money.

What a TradeFundrr options account supports

TradeFundrr options accounts trade calls and puts on hundreds of liquid US underlyings, intraday only. They do not hold shares, so a classic covered call cannot be built there. The supported structures include long calls and puts, spreads, iron condors and butterflies, with credit-based positions allowed up to account buying power.

What the account pages say

The options Pre-Prop and Prop pages list calls and puts on liquid US underlyings, including index options such as SPX and ETF options on SPY, QQQ and IWM. They list outright long calls and puts, spreads, iron condors and butterflies as supported, with credit-based positions allowed up to account buying power. Trading is manual and intraday only, with no swing positions, Monday through Friday from 9:30 AM to 3:55 PM ET, and each trade must be held for at least 15 seconds. Contract limits per leg differ between Pre-Prop and Prop, and buying-power and risk limits apply, so confirm the current figures in your own account terms.

Both accounts start with $25,000 in buying power. They carry a $1,000 daily loss limit that pauses trading for the rest of the session when reached, and a $3,000 maximum drawdown that trails the highest end-of-day balance and closes the account if it is reached. Pre-Prop is a simulated evaluation account. Prop is a simulated funded account with no evaluation.

Whether a single short put on its own qualifies as a permitted credit position is a question for your account terms and the support team, not an assumption. If you want to sell premium, check first.

The defined-risk cousins

The structures the account supports are where the payoff logic of covered calls and cash-secured puts lives on. A bull put spread, for example, sells a put and buys a lower-strike put. It collects a premium like a cash-secured put, has the same "fine if the stock stays above the strike" profile, but the long put sets a floor under the loss. The trade-off is a smaller premium in exchange for a known maximum loss. Our guide to debit spreads versus credit spreads covers how those structures are built and sized.

Defined risk fits an account with a daily loss limit and a trailing drawdown. A short option with stock-sized downside can, in a fast move, consume a large share of a $3,000 drawdown on a single position. A spread caps that number before you enter, which makes it much easier to size against the written limits.

Why learn the classic strategies anyway

Covered calls and cash-secured puts are worth understanding even if your funded account will never hold either one. They teach the core logic of option selling: you are paid to accept an obligation, the premium reflects time and implied volatility, and your real risk is the stock's risk, not the premium you collected. Many traders also run these strategies in their own personal accounts, with their own money, and the same discipline applies there.

A simulated account is a sensible place to practice the parts that transfer: reading premium, choosing strikes, defining your maximum loss in dollars before you enter, and closing a position that has moved against you rather than hoping. Those habits are what make an option-selling strategy survivable in any account.

Frequently Asked Questions

What is the difference between a covered call and a cash-secured put?

A covered call sells a call against shares you own and caps your upside for a premium. A cash-secured put sells a put while holding the cash to buy the shares, and pays you to wait for a lower entry price. At expiration their payoff shapes are very similar.

What is the maximum loss on a covered call?

The stock purchase price minus the premium received, if the stock goes to zero. The premium cushions a fall but does not prevent one, so the risk is close to that of owning the shares outright.

What is the maximum loss on a cash-secured put?

The strike price minus the premium received, if the stock goes to zero after you are assigned. That is less than buying the shares outright at today's higher price, but it is still substantial.

Can I sell covered calls in a TradeFundrr account?

No. TradeFundrr options accounts trade calls and puts, not shares, so there are no shares to cover a short call. The accounts are also intraday only, with no swing positions.

Can I sell cash-secured puts in a TradeFundrr options account?

Not in the classic sense. The accounts are intraday and simulated, so nothing is held toward assignment. The pages allow credit-based positions up to account buying power, but confirm in your account terms whether a standalone short put is permitted.

Can my option be assigned in a funded account?

No. Assignment is a live-market event that happens when a real contract is exercised through the clearing system. A TradeFundrr account is simulated, no real trade is executed, and positions are closed within the session.

Are covered calls a safe strategy?

They are lower risk than selling calls without shares, but not safe in any absolute sense. The writer keeps nearly all of the stock's downside and gives up much of its upside while the call is open.

Which supported strategy is closest to a cash-secured put?

A bull put spread. It sells a put and buys a lower-strike put, so it collects premium with a similar profile above the strike, but the long put caps the maximum loss. Spreads are listed as supported on the options account pages.

Covered calls and cash-secured puts are honest strategies when they are used honestly: by someone who owns the shares and is happy to sell, or has the cash and is happy to buy. The premium is payment for that obligation, not a bonus on top of it.

In an intraday, simulated options account the classic versions do not apply, but their lessons do. Know your obligation, define your maximum loss in dollars before you enter, and choose structures that fit the written limits of the account you are actually trading.
