What Is a Strip?

A strip is a three-leg volatility strategy in which you buy one call and two puts on the same underlying with the same strike and expiration, usually at the money. It is a long straddle with an extra put, which tilts the position toward the downside. You still profit from a large move in either direction, but a fall of a given size pays roughly twice as much as a rise of the same size.

The legs work as an unbalanced pair. If the stock rallies, the single call gains one dollar per share above the strike while both puts expire worthless. If the stock falls, the two puts together gain two dollars per share below the strike while the call expires worthless. The extra put costs more premium than a plain straddle, so the debit is larger and the upside breakeven moves further away, while the downside breakeven moves closer because the two puts recover the debit twice as fast.

The payoff diagram is an asymmetric V. Both arms rise from the maximum loss point at the strike, but the left arm is twice as steep as the right. Before expiration the position carries a negative delta of roughly 50 per strip at the money, equivalent to being short about 50 shares, along with long gamma and long vega. It suits a trader who expects a big move, thinks a fall is more likely than a rally, but wants to keep meaningful profit potential if the move goes the other way.

Strip Example

XYZ trades at $100 with 45 days to expiration. You buy one $100 call for $4.20 and two $100 puts for $3.80 each, or $7.60. The net debit is $11.80 per share, or $1,180 per strip. The upper breakeven is $111.80 and the lower breakeven is $94.10.

Stock at expiration	Result
$100 (unchanged)	All three options expire worthless. You lose the entire $1,180 debit, the maximum loss.
$111.80 or $94.10	Breakeven. At $111.80 the call is worth $11.80, and at $94.10 the two puts are worth $5.90 each. Either way the value exactly offsets the debit and P&L is $0.
$85	Each put is $15.00 in the money for a combined $30.00, and the call is worthless. The position is worth $3,000, so profit is $3,000 minus the $1,180 debit, or +$1,820.
$115	The call is $15.00 in the money and both puts are worthless. The position is worth $1,500, so profit is $1,500 minus the $1,180 debit, or +$320.

Maximum loss is the $1,180 debit if XYZ closes at exactly $100. A $15 fall earns $1,820 while a $15 rally earns $320, which is the whole point of the extra put. Profit is unlimited above $111.80, and below $94.10 it grows by $200 for every dollar the stock declines.

When to Use a Strip

You expect a large move and believe a decline is more likely than a rally, but you are not confident enough to hold a pure put position.
A binary event is approaching where the bad outcome would trigger a crash while the good outcome would produce only a modest rally, such as a regulatory decision or a debt refinancing deadline.
Implied volatility is low relative to its history, so the three long options are cheap and an IV rise will help the position.
You want downside protection for a portfolio with more leverage than a single put provides, while keeping some upside participation.
Typical entries use at-the-money strikes with 30 to 90 days to expiration so that the three premiums do not decay too quickly before the move arrives.

Risks to Understand

Three long options mean roughly one and a half times the theta of a straddle. The position bleeds time value quickly, especially in the final weeks.
The debit is larger than a straddle, so the upside breakeven is further away and a moderate rally may still lose money even though the direction was right.
An implied volatility crush after an event can shrink all three options at once, and the two puts are hit hardest if the market reads the news as calming.
The maximum loss is the full debit if the stock finishes exactly at the strike, and it is a larger dollar amount than a straddle or strangle on the same stock.
Because the position is short delta at entry, a slow grind higher costs money on two fronts: the puts lose value from both the price move and time decay while the single call gains slowly.

Managing the Trade

Set a profit target in advance and take it after the anticipated move, since a strip is priced to profit from a single sharp move rather than a long trend.
After a sharp decline, sell one put to lock in gains and convert the remainder into a plain straddle, keeping exposure to a further move in either direction.
If the stock rallies instead, the two puts lose value fast; consider selling them and holding the call if you now believe the rally will continue.
Close or reduce the position at the midpoint of the trade if the stock has not moved, because three options decaying together is expensive to hold.
For event trades, exit immediately after the catalyst before implied volatility collapses, regardless of whether the move was large enough.

Strip FAQs

What is a strip option strategy?: A strip is a long straddle with a second put added: one call and two puts at the same strike and expiration. It profits from a large move in either direction but pays about twice as much on a decline as on a rally of the same size. It is used when a trader expects high volatility with a bearish lean.
How do you calculate strip breakeven?: The upper breakeven is the strike plus the total premium paid, because only one call is working above the strike. The lower breakeven is the strike minus half the total premium, because two puts recover the debit twice as fast. For a $100 strip costing $11.80, the breakevens are $111.80 and $94.10.
Strip vs strap: what is the difference?: A strip has two puts and one call and leans bearish; a strap has two calls and one put and leans bullish. Both are modified straddles that profit from a large move in either direction but pay roughly twice as much in the favored direction. Choose the strip when you think a fall is more likely and the strap when you think a rally is more likely.
Is a strip better than buying two puts?: Two puts alone lose everything if the stock rallies. The strip adds a call so that a large rally still produces a profit, at the cost of a higher debit and a lower breakeven on the downside. It is a hedge against being wrong about direction while keeping most of the downside leverage.
What is the max loss on a strip?: The maximum loss is the total premium paid for all three options, multiplied by 100. It occurs if the stock closes exactly at the strike at expiration, where the call and both puts expire worthless. In the example that is $1,180 per strip.
What is the delta of a strip?: At the money, a call has a delta near 0.50 and a put near negative 0.50, so one call and two puts net to roughly negative 0.50, or about 50 shares short per strip. The delta becomes more negative as the stock falls and moves toward neutral, then positive, as the stock rises past the strike.
