What Is a Married Put?

A married put is a risk management strategy where an investor purchases shares of stock and simultaneously buys a put option on those shares. The term 'married' refers to the fact that the stock and put are purchased together at the same time, creating a single combined position from inception. This distinguishes it from a protective put, which is added to an existing stock position.

The married put provides a defined-risk way to invest in stocks. Your maximum loss is limited to the difference between the stock price and the put strike, plus the put premium. Meanwhile, you retain full upside potential above the breakeven price. This makes it ideal for investors who want to participate in a stock's upside but cannot afford a large drawdown.

Married Put vs. Protective Put

A married put is purchased at the same time as the stock. A protective put is added to shares already owned. Functionally identical, but the tax treatment may differ. In the US, a married put may affect the stock's holding period for capital gains purposes.

Married Put Formula

Total Investment
Total Cost = (Stock Price + Put Premium) × Number of Shares
Where:
Stock Price = Purchase price per share
Put Premium = Cost of the protective put per share
Maximum Loss
Max Loss = (Stock Price - Put Strike + Put Premium) × Shares
Where:
Max Loss = The worst-case scenario regardless of stock decline
Breakeven
Breakeven = Stock Price + Put Premium
Where:
Breakeven = Stock price needed to cover the combined cost
Married Put Example
Given
Stock Price
$100
Put Strike
$95
Put Premium
$3.00
Shares
100
Calculation Steps
  1. 1Total investment = ($100 + $3.00) × 100 = $10,300
  2. 2Max loss = ($100 - $95 + $3.00) × 100 = $800
  3. 3Breakeven = $100 + $3.00 = $103.00
  4. 4Max loss % = $800 / $10,300 = 7.77%
  5. 5If stock drops to $50: stock loss $5,000, put gain $4,500, net loss = $800
  6. 6If stock rises to $120: profit = ($120 - $103) × 100 = $1,700
Result
For $10,300 total investment, your maximum loss is capped at $800 (7.77%) regardless of how far the stock falls. The stock must reach $103 for you to break even, accounting for the $3 put premium.

Implementing a Married Put

1
Buy Stock and Put Together
Place both orders simultaneously. The put should have the same number of contracts as lots of 100 shares. Ensure the put expiration gives you enough time for your thesis.
2
Choose Acceptable Risk Level
The put strike determines your floor. ATM puts ($100 put on $100 stock) provide maximum protection but cost the most. 5% OTM puts balance cost and protection.
3
Monitor and Adjust
If the stock rises, consider rolling the put up to lock in gains. If the put nears expiration and you still want protection, buy a new put at the current appropriate strike.
  • Married puts define your maximum risk from day one
  • The put premium is the 'insurance cost' that reduces returns in bullish markets
  • Ideal for volatile stocks where drawdowns could be large
  • The combined position has the same payoff profile as a long call option
  • Tax treatment: the put premium may be added to the stock's cost basis
~
Synthetic Long Call

A married put (long stock + long put) has the exact same payoff profile as a long call option at the put strike. The difference is that you own the shares (receiving dividends) and have more control. Understanding this equivalence helps you compare strategies and choose the most efficient approach.

!
Cost Drag

The put premium reduces your returns in every scenario where the stock does not decline significantly. If you buy married puts consistently, the annual cost (5-15% of position value) can significantly drag on long-term returns. Reserve this strategy for situations where downside protection is genuinely needed.

Frequently Asked Questions

A married put (stock + put) and a long call have the same profit/loss profile at expiration. However, the married put involves owning the stock, so you receive dividends, have voting rights, and can sell covered calls. A long call is more capital-efficient (costs less) but does not provide dividends or stock ownership benefits. The married put also has different tax treatment.
