NFLX bull put spread: credit, risk, strikes
A single-print name: the stock spends the quarter grinding and then gaps on subscriber and margin numbers. Front-month IV going into earnings is the highest in large-cap media, and the post-print crush is brutal by design.
A bull put spread sells the $69 put and buys the $68 put for protection, both expiring Aug 28. On NFLX at $71.71 that pays $28 up front against $72 of defined risk, with 66% probability of keeping the credit. It is the cash-secured put's capital-efficient cousin.
The trade, priced from the chain
27d to August 28, 2026| Leg | Qty | Price | Δ | IV | Cash |
|---|---|---|---|---|---|
| SellAug 28 $69 put | 1 | $1.45 | -0.31 | 35% | +$145 |

Every leg above is priced at the chain’s own quote — the identical number the builder will show you when you click through (last traded price), captured August 1, 2026 with a 15-minute delay. Only strikes whose print survives an implied-volatility check (within 20% of its own IV) and a no-arbitrage check across the ladder are priced here. Full methodology. Greeks, breakevens, max profit/loss and probability of profit are computed by OptionTracker’s engine at r = 4.2%. Educational analysis, not investment advice.
Yield on the capital this actually ties up
Annualized figures assume the same trade repeats every 27 days at the same premium. Nothing does. Use them to compare strikes and tickers, not to forecast a year.
How a bull put spread works
You are still selling downside — just not all of it. The long $68 put cuts the tail off below that level, which is why this needs $72 of buying power instead of the $6,900 a cash-secured put would tie up.
Above $69 at August 28, 2026, both puts expire worthless and you keep the full $28. Below $68, you lose the maximum $72. Breakeven is $68.72.
Return on risk is 39% for 27 days — 526% annualized. That headline is the reason people prefer spreads to cash-secured puts, and the reason spreads blow up accounts: the same capital supports several times the notional risk.
When it makes sense
- You are constructively bullish on NFLX but do not want to commit $6,900 of cash to a single short put.
- IV is rich — at 36% ATM, NFLX is the 10th richest of the 20 underlyings on this site — and you want to be short vega.
- You want a hard floor. The long wing turns an open-ended obligation into a known $72.
- The buying power this consumes is capital you were not planning to deploy elsewhere before the expiry.
Where the risk actually is
The risk is leverage, not the structure. $72 per spread is small; the temptation to sell ten of them because the buying power allows it is how a 66%-win-rate trade produces a losing year.
Between the strikes the loss scales linearly, so most of the damage happens fast when NFLX breaks $69. There is no assignment-and-hold escape hatch: the long put you own expires the same day.
Early assignment is an operational risk rather than a market one: it arrives on a weekend, converts a defined structure into a stock position, and requires cash you may have allocated elsewhere.
Reading the NFLX chain
Netflix pays premium sellers well for eleven weeks and takes it back in one evening. The structural trade is to sell the post-print month, when IV has been crushed but the stock has already made its move and has no catalyst until the next release — that is where the implied-to-realized gap on this name is actually positive, and it is the opposite of when the credits look most attractive.
NFLX's Aug 28 strikes are $1 apart near the money (1.39% of spot). Coarse enough that the strike you want frequently does not exist, and the nearest rung is a different trade. 27k contracts of open interest on Aug 28 is workable around the money and thin in the wings — width costs more here than the ladder suggests. 32 strikes on that expiry — 50% of the board — carry prints that agree with their own implied volatility and hold up across the ladder, and those are the strikes priced here. Liquid around the money; the wings can be wide, and legging a four-sided structure here costs real money.
Skew is inverted: the 25-delta CALL implies 1.5% more vol than the put. That is the market pricing upside risk above downside risk — a squeeze, a takeover rumour, or a crowded short. Selling calls into an inverted skew pays better than usual and is riskier than usual for exactly the same reason. The term structure is flat inside 1.5% between the two captured expiries, so there is no calendar edge to harvest and no event visibly priced into one month over the other.
At 36% ATM implied vol, the Aug 28 options are pricing a one-standard-deviation move of $7.03 over 27 days — roughly −9.8% to +9.8%, or $64.68 to $78.74. The structure above sells the part of that distribution the market thinks it will not reach. Whether that is a good trade is entirely a question of whether 9.8% is too much or too little for NFLX over 27 days — the delta table cannot answer that, and neither can we.
The specific way people lose money on NFLX: Holding any short-vol structure through the print because the delta looked safe. The implied move on this name is routinely exceeded.
Picking the strike on NFLX
Place the short strike on delta, then choose the width you can afford to lose. On NFLX at $71.71:
| Band | What it means | When it fits |
|---|---|---|
| 0.10 – 0.16 Δ short | Well below the market | High probability, thin credit. Needs strict sizing; the tail still exists.On NFLX: the Aug 28 $65 put at $0.53, 10% annualized |
| 0.20 – 0.30 Δ short | The standard credit-spread band | Credit ≈ 1/3 of width is the usual quality bar. Most spreads live here.On NFLX: the Aug 28 $68 put at $1.17, 22% annualized |
| 0.35 – 0.45 Δ short | Close to the money | Rich credit, frequent management. You are taking a real directional view.On NFLX: the Aug 28 $71 put at $2.24, 42% annualized |
| Width | Sets max loss per spread | Narrower = smaller risk per unit, worse credit/width ratio after fees. |
The live Aug 28 put chain below carries the deltas. Credit divided by width is the number to compare across strikes — anything under 25% is usually not worth the tail you're renting out.
From the far strike to the near one, the premium below moves by a factor of 6.3. Where you sit on that curve is the trade. Open interest concentrates at $65 on this expiry, which is usually where the fills are cleanest.

Managing the position
- Set a stop at roughly 2× the credit. Credit spreads that go against you tend to keep going.
- Never let a tested spread ride into expiry week hoping for pin luck — assignment mechanics on one leg are messier than the loss you were avoiding.
- Watch the extrinsic value on any short leg that goes in the money. When what is left is less than a dividend or a financing cost, exercise becomes rational for the person on the other side.
- Do not add to a tested position to lower the average. Averaging into short premium works right up until the one time it does not, and that time is the one that matters.
Common mistakes
Treating it as a cash-secured put
A CSP that goes wrong leaves you owning NFLX at a basis you chose. A put spread that goes wrong leaves you with $72 gone and no shares. Different trades, different plans.
Selling spreads in low IV
Credit spreads are short vega. Selling them when NFLX's 36% IV is at the low end of its range means you collect little and own the risk of vol expanding.
Sizing against buying power
Margin requirement is what the broker will let you do, not what you should do. The relevant limit is the loss you can absorb without changing the plan.
NFLX bull put spread FAQ
How much buying power does this NFLX put spread need?
About $72 per spread — the width minus the credit. Compare that with $6,900 for the equivalent cash-secured put.
Can I be assigned before expiry?
Yes, on the short $69 put if it goes deep in the money — most likely around an ex-dividend date or in the final week. You would be long 100 shares and still hold the long put as protection until August 28, 2026.
How much is NFLX expected to move by Aug 28?
The Aug 28 options imply a one-standard-deviation move of $7.03 — about 9.8% of the NFLX share price — over the 27 days to expiry. That is the market's estimate, not a forecast: roughly a third of the time the actual move is larger.
Is NFLX option skew favouring puts or calls?
Calls. The 25-delta call implies 1.5% more volatility than the 25-delta put on the Aug 28 chain — an inverted skew, usually a sign of squeeze or event risk to the upside.
