Cash-Secured Put Case Study — Getting Paid to Wait for the Right Price

The Setup

The Limit Order That Earns Nothing

Marcus wanted to buy 100 shares of a tech company he'd been watching. The stock was trading at $102. His target entry price was $95. He set a limit buy at $95 and waited.

Three weeks later, the stock was still above $98. His cash sat idle in the account earning nothing. A friend suggested an alternative: sell a cash-secured put at the $95 strike and get paid while waiting for the price to come down.

Marcus sold a $95-strike put with 30 days to expiry and collected $230 upfront. If the stock didn't fall to $95, he kept the premium and could sell another put next month. If it did fall and he was assigned, his effective cost basis would be $95 minus all the premiums he'd collected — a better entry than the limit order alone.

Instead of a limit order sitting idle, my cash was working for me the entire time I waited for the right price.

The Full Sequence

Month by Month

Month 1

First Put Sold — $230 Collected

Sold $95 put, 30-day expiry. Stock stayed above $98. Option expired worthless. Kept $230 — did not buy shares.

Month 2

Repeat — $240 Collected

Stock dipped to $97 briefly, then recovered. Option expired again. Another $240 in the account. Running total: $470 in premium. Still no shares.

Month 3

Assigned at $95 — Effective Cost: $88.20

Broader market sell-off pushed stock to $91. Marcus was assigned — bought 100 shares at $95. But with $680 in premium collected, effective cost basis: $88.20. Stock recovered to $101 within 6 weeks.

Post-Assignment

Immediately Began Selling Covered Calls

Now holding 100 shares at an $88.20 cost basis, Marcus switched to the covered call strategy — continuing to collect premium income on the position.

Entry Comparison

Limit Order vs. Cash-Secured Put

Strategy	Outcome
Limit order at $95	$95.00 cost basis
CSP Month 1 premium	−$2.30 / share
CSP Month 2 premium	−$2.40 / share
CSP Month 3 premium	−$2.10 / share
Effective cost basis	$88.20 / share
Discount vs. limit order	7.2% lower

The cash-secured put didn't just get Marcus into the stock — it got him in $6.80 per share cheaper than his original target, while paying him $680 in the process.

Mechanics

How a Cash-Secured Put Works

01

Reserve Cash

Set aside enough cash to buy 100 shares at your target strike price.

02

Sell the Put

Choose a strike at or below your desired entry. Collect premium immediately.

03

Two Outcomes

Stock stays above strike → premium kept, repeat. Stock falls → assigned at strike, reduced by premium.

04

Begin Covered Calls

Once assigned shares, start the Wheel by selling covered calls against the position.

Key Takeaways

A cash-secured put is a superior alternative to a limit buy order — you get paid while you wait, and your entry price is lower if assigned.
The premium you collect becomes a permanent reduction in your cost basis. Three months of CSPs can meaningfully improve your entry price.
If you're never assigned, that's still a win — you collected premium income without ever owning the stock.
This strategy works best on stocks you genuinely want to own. Don't sell puts on stocks you wouldn't be comfortable holding if assigned.
Assignment during a broader market sell-off is common. Position sizing matters — only sell puts on stocks you can afford to hold through volatility.
