What I’m Going to Cover

I’ve been trading options for years, and the sell put (or cash-secured put) is my go-to strategy for generating income while waiting to buy stocks I already want. Let me walk you through a real example with actual numbers so you see exactly how it works – including the risks and rewards.

Quick Refresher: What Is a Sell Put?

When you sell a put option, you’re giving someone else the right to sell you 100 shares of a stock at a specific price (the strike price) on or before expiration. In return, you collect a premium upfront. You’re essentially saying, “I’m willing to buy this stock at $X, and if it stays above that, I keep the premium as free money.”

Step-by-Step Example: Selling a Put on XYZ Stock

Let me take you through a trade I actually considered recently. I’ll use hypothetical numbers, but they’re realistic.

The Setup

  • Stock: XYZ Corp (currently trading at $50)
  • My target buy price: $45 (I’d be happy to own XYZ at $45)
  • Option: Sell 1 put contract (covers 100 shares) with a strike price of $45, expiring in 30 days
  • Premium received: $2.00 per share (that’s $200 total for one contract)
  • Margin requirement (cash secured): $4,500 ($45 × 100) held in cash, but I only need to have that amount available – I don’t actually pay it unless assigned.
I like that the premium gives me a 4.4% return in just 30 days ($200 / $4,500) if the stock stays above $45. That’s a 53% annualized return – but remember, this is not risk-free.

Scenario 1: Stock Stays Above Strike – Keep the Premium

If XYZ stays at $50 or even falls a bit but stays above $45, the put expires worthless. I keep the $200 premium. My buying power is freed up, and I can sell another put. No shares are bought, and I made a tidy profit.

ConditionOutcome
XYZ closes at $48 (above $45)Option expires OTM, keep $200. No shares assigned.
XYZ closes at $45.01Same – still above strike, keep full premium.

Scenario 2: Stock Falls Below Strike – Get Assigned

This is where the real risk shows up. If XYZ drops to, say, $40 by expiration, the put is in the money, and I’ll be assigned. I’ll have to buy 100 shares at $45 each, even though the market price is $40. My total cost: $4,500 for shares worth $4,000 – an immediate unrealized loss of $500. But wait, I already collected $200 in premium, so my net cost is $4,300 ($4,500 - $200), or $43 per share. Compared to the market price of $40, I’m still $300 underwater.

Stock Price at ExpirationNet Cost (after premium)Unrealized P&L
$40$43-$300
$42$43-$100
$44$43+$100
$45$43+$200

I’ve been in this situation before. I got assigned on a stock I really wanted, but it dropped further. The key is to only sell puts on stocks you’re willing to hold long-term. That way, even a temporary loss doesn’t scare you.

Calculating Your Real Return

Let’s say the stock stays above strike. My return on cash secured is $200 / $4,500 = 4.44% in one month. If I do this 12 times a year (though not always possible), that’s over 50% annualized. But don’t get carried away – markets can turn.

Why I Prefer This Over Buying Stock Directly

I used to just buy shares, but selling puts gives me two advantages:

  • I get paid while I wait for a better entry price.
  • I often buy at a discount to the current price. For example, with XYZ at $50, my effective purchase price after premium is $43 if assigned – that’s 14% below market.

Of course, there’s a downside: if the stock rockets to $60, I miss out on that gain because I’m not holding shares – I only have the $200 premium. But I sleep better knowing I’m not overpaying.

Common Mistakes to Avoid When Selling Puts

I’ve made my share of errors. Here are the ones I see most often:

  • Selling puts on stocks you don’t want to own. If the stock tanks, you’re stuck with shares you hate. Stick with companies you’re bullish on long-term.
  • Ignoring volatility. High IV means higher premiums, but also higher risk. I once sold a put on a biotech stock with huge IV – got crushed when it collapsed.
  • Not having enough cash. A cash-secured put requires you to have the full strike price in cash (or margin). If you overcommit, a sudden assignment can force you to sell other positions.

FAQ About Sell Put Option Examples

What happens if the stock drops to $0? Can I lose more than the premium?
Yes, you can lose a lot. If the stock goes to zero, you’re forced to buy it at the strike price – a total loss of the strike minus premium. That’s why I never sell puts on bankrupt-prone companies. Always size your trades so that a total loss wouldn’t wipe you out.
Can I close the put early to lock in profits?
Absolutely. If the stock jumps shortly after you sell the put and premium drops, you can buy back the option for a profit. I often close at 50% profit to reduce risk. For example, if I collect $2 and the put is now worth $1, I close and take $100 profit (less commissions).
How much buying power do I really need for a cash-secured put?
You need at least the strike price times 100 per contract, minus the premium received. But most brokers will only require the full amount if assigned. In my experience, it’s smart to have a cash cushion – I keep at least 110% of the strike.
What’s the best expiration and strike for a first trade?
For beginners, I recommend selling puts 30-45 days out, with a strike 5-10% below the current price. That gives you a decent premium and a buffer against small drops. I started with 30-day expirations on Apple around 5% OTM – worked great.

This strategy isn’t for everyone, but if you’re patient and pick quality stocks, selling puts can be a steady income stream. My personal rule: never sell a put unless you’d be happy buying the stock at the strike price. That simple mindset has saved me from many bad trades.
