How to Sell Cash Secured Puts on Fidelity

Selling a cash-secured put on Fidelity means you agree to buy 100 shares of a stock at a set price if the option is assigned to you. In return, you receive an option premium from the buyer.

The key detail is the cash. In a cash account, Fidelity requires the full strike price multiplied by 100 shares to be held in cash. Shares you already own can't be used as collateral for this requirement.

That cash math should come before you choose a stock or open the options chain. If you aren't comfortable buying the shares at the strike price, selling the put probably isn't the right trade.

What selling a cash-secured put means

A put option gives its buyer the right to sell shares at a set price, called the strike price, before or at the option's expiration date. The seller of that option takes on the matching obligation to buy the shares at the strike price if assigned.

A standard stock option contract represents 100 shares.

So, when you sell one put with a $40 strike price, you may have to buy:

• 100 shares
• At $40 per share
• For a total purchase price of $4,000

You receive a premium for accepting that obligation. The premium is the price the option buyer pays. It is usually shown on a per-share basis, so a quoted premium of $1.00 means $100 for one contract before fees or other costs.

A cash-secured put is usually sold on a stock you believe will stay around its current price or rise. This is called a neutral-to-bullish view. You aren't betting that the stock must skyrocket. You may simply think it won't fall below the strike price, or you may be willing to buy it at that price.

Selling a put versus buying a put

These two trades move in opposite directions:

• Selling a put: You receive a premium and take on an obligation to buy shares if assigned.
• Buying a put: You pay a premium for the right to sell shares at the strike price.

A person buying a put may be trying to protect an existing stock position or bet on a stock falling. A person selling a cash-secured put is generally prepared to own the stock.

The cash-secured version is different from selling an uncovered, or “naked,” put. With a cash-secured put, you set aside the money needed to buy the shares. That makes the obligation visible in your account before you place the trade.

Fidelity account and options-trading requirements

Before selling cash-secured puts, you'll need a Fidelity brokerage account. The basic preparation has three parts:

1. Open a brokerage account.
2. Fund the account with enough cash.
3. Apply for and receive approval to trade options.

Having a Fidelity account does not automatically mean you can place options trades. Fidelity reviews your application and determines what options trading access is available to you. Approval can depend on information in your application, so check the current requirements inside your account.

You also need settled, available cash for the put. Cash that is committed to another trade or is not available for trading may not satisfy the requirement. The amount shown during order review is the number to pay attention to.

If you use a cash account, the required amount for one cash-secured put is:

> Strike price × 100 shares

For example, a $30 put requires $3,000 in cash for one contract. Ten contracts would require $30,000.

Your existing shares don't replace this cash. A stock position in your account cannot be used as collateral for the cash-secured put requirement.

Fidelity's website and app can change over time. The names of menus, buttons, and approval screens may not look exactly the same when you log in. Treat the current screens in your account as the source of truth.

How much cash to set aside before selling

Start with the strike price, not the current stock price.

Suppose you want to sell one put with a $45 strike. The basic cash requirement is:

$45 × 100 = $4,500

That is the amount to plan on holding in cash for one contract in a cash account. If you sell three contracts, the calculation becomes:

$45 × 300 = $13,500

The premium you receive doesn't change the basic calculation used here. You should have the full strike-price amount available before placing the order. Don't assume that owning shares, having buying power in another part of the account, or receiving the premium will replace the required cash.

You may also want to leave extra room in the account. The exact amount you need depends on the account and order details shown by Fidelity. A trade that uses every available dollar gives you little flexibility if the position is assigned or another transaction is pending.

The practical question is simple:

> If Fidelity required me to buy 100 shares at this strike price, could I pay for them without selling something else?

If the answer is no, the contract is too large for your current cash position.

How to find and choose a put option on Fidelity

Once your account has options approval and enough cash, find the stock or exchange-traded fund you are considering in Fidelity's trading tools. From there, open the option chain. An option chain is the table that lists available expiration dates, strike prices, and premiums.

For a cash-secured put, you are usually looking at a put that is at the money or out of the money:

• At the money means the strike is close to the stock's current price.
• Out of the money means a put's strike is below the current stock price.

Review the put side of the chain and check:

• The expiration date
• The strike price
• The quoted premium
• The number of contracts
• The cash requirement shown by Fidelity
• The stock price and the size of the position you may receive

The expiration date is the date connected to the option contract. Selling weekly cash-secured puts means using options that expire about a week away. A weekly option can require less time for the trade to work, but the stock can still move sharply during that short period. A weekly expiration does not make the trade safer.

Don't choose a strike only because its premium looks attractive. First ask whether you would genuinely want 100 shares at that price. The premium is payment for taking on the obligation, not a guarantee that the trade will end profitably.

Step-by-step: entering a cash-secured put order

The exact Fidelity layout may change, but the order usually follows this path:

1. Open the option chain

Search for the stock or fund in Fidelity's trading area and select its options. Choose the expiration date you want to review.

2. Select the put side

Find the strike price that fits your plan. Check the corresponding put quote rather than a call quote. Calls and puts are different contracts with different obligations.

3. Choose to sell to open

To create a new short option position, select Sell to Open. “Short” here means you sold the option first and may later buy it back to close the position.

This is different from Sell to Close, which is used to exit an option you previously bought.

4. Enter the number of contracts

One contract usually represents 100 shares. Enter only the number of contracts you could afford to have assigned.

If one contract requires $4,800 in cash, five contracts would create a possible $24,000 stock purchase. Make sure the number of contracts matches your cash and your willingness to own the shares.

5. Review the order price

The premium is commonly quoted per share, even though the contract covers 100 shares. A $0.75 premium would represent about $75 for one contract before fees and other costs.

Review the order type and price carefully. If you enter a limit order, your order will be submitted with the price you specify or the current settings shown by Fidelity. If you use another order type, understand how Fidelity describes its execution before submitting it.

6. Check the cash requirement

Before sending the order, review the estimated cash commitment and the number of shares connected to the contract. This is where you can catch a common mistake: focusing on the premium while overlooking the full strike-price obligation.

7. Submit and confirm the order

Read the contract details one more time:

• Buy or sell
• Open or close
• Put or call
• Strike price
• Expiration date
• Number of contracts
• Premium
• Cash requirement

Submit the order only after those details match your plan. An order may remain unfilled if the market doesn't accept the price you entered. Check the order status instead of assuming it went through.

Cash-secured put example

Assume a stock is trading at $52. You choose to sell one put with:

• A $48 strike price
• One contract
• An expiration date you selected
• A quoted premium of $1.20 per share

The cash requirement is based on the strike:

$48 × 100 = $4,800

The premium received would be:

$1.20 × 100 = $120

If the stock stays above $48 through the relevant expiration process and the option expires without assignment, you keep the premium, subject to fees and the actual terms of the trade.

If the stock falls below $48 and the put is assigned, you must buy 100 shares for $4,800. The $120 premium reduces your effective purchase cost to $4,680 before fees, or $46.80 per share. That doesn't remove the risk. If the stock then trades much lower, the shares can be worth less than what you paid.

The main point of the example is the order of the math:

1. Calculate the possible stock purchase: $48 × 100.
2. Confirm that $4,800 is available in cash.
3. Consider the premium as payment for accepting the obligation.
4. Decide whether owning the shares at the strike price still makes sense if the stock drops.

What happens after the put is sold

After the order fills, the option is open. The cash connected to the possible share purchase remains committed according to the account's requirements.

Three broad outcomes are possible:

• The stock stays above the strike: The put may expire without assignment, and you may keep the premium.
• The stock falls below the strike: You may be assigned and required to buy 100 shares at the strike price.
• You close the position before expiration: You may buy back the put, if the current market and Fidelity's order process allow it.

The stock's market price can move quickly. A put that looked comfortably out of the money when sold can become in the money later. In the money means the stock price has moved below the strike for a put.

Don't think of assignment as Fidelity buying shares for you at a discount. You are accepting the shares at the strike price, and the market value could be lower at that moment.

Can you sell the cash-secured put early?

You may be able to close an open short put before expiration by buying the same option back. That is generally called Buy to Close. However, the exact Fidelity workflow, available order choices, and account rules can change.

Before trying to exit, verify the current order screen and make sure you are closing the existing position rather than opening another one. Check all of these details:

• The same underlying stock or fund
• The same expiration date
• The same strike price
• The same number of contracts
• The action marked as closing the position
• The current cost to buy the option back

Buying the put back may cost more than the premium you received. In that case, the trade can produce a loss even if you avoid assignment. If the option price has fallen, buying it back may cost less than the original premium, though fees and the actual fill price still matter.

Don't place an early-exit order based on a remembered Fidelity tutorial or an old screen. Verify the current interface and the position details in your account first.

Main risks and when the strategy may fit

Selling cash-secured puts is not risk-free income. The premium is limited, while the stock can fall far below the strike price.

The main risks are:

• You may have to buy the shares. Assignment creates a stock position you must be ready to own.
• The shares may be worth less than the strike price. A falling stock can cause a loss that is much larger than the premium received.
• Your cash is tied up. Money reserved for the put may not be available for other trades.
• You may miss a sharp rise. If the stock climbs, you generally keep the premium but don't receive the full upside from owning the shares earlier.
• Weekly options can move quickly. Short time periods do not remove market risk.

The strategy may fit someone who has already researched the stock, wants to buy it at a lower price, and has enough cash to purchase 100 shares per contract. It is a poor fit if you are mainly chasing the premium or would be forced to sell other investments to meet assignment.

Options involve risk, and account eligibility rules can change. Before placing a trade, verify your Fidelity options approval, the cash requirement shown for your account, and the current order-entry details in Fidelity's interface.
