The
Strip

What is a strip?

A strip is a long-volatility options strategy built by buying two puts and one call, all at the same strike price and the same expiry. It is essentially a long straddle with an extra put bolted on, which skews the payoff so that a fall earns roughly twice as fast as an equal-sized rally.

You buy a strip when you are convinced a large move is coming but think the odds favour the downside — perhaps ahead of a results announcement, a policy decision or a global event where bad news could hit harder than good news lifts. Like any long-premium trade, the cost is the total debit paid, and that debit is also the most you can lose.

Key takeaways

• A strip is a long-volatility, bearish-tilt trade — two puts and one call at the same strike and expiry.
• It profits from a big move either way, but the downside gain builds about twice as fast as the upside.
• Your loss is capped at the net premium paid for the three options.
• The worst outcome is a flat market that pins the underlying at the strike, where all three legs decay to zero.
• You pay full premium up front, so there is no margin beyond the debit — but theta and IV crush work against you.

How a strip works

Construction is simple: pick a strike (usually at-the-money), then buy two puts and one call there for the same expiry. Below the strike all three combine so each point of fall earns on two puts at once; above the strike only the single call gains, so each point of rise earns half as fast. The V-shaped payoff therefore has a steep left arm and a gentler right arm, meeting at a low point right at the strike.

Because every leg is bought, the trade costs a net premium and needs no SPAN margin — you simply pay the debit. The flip side is that the position bleeds theta every day and is hurt by a drop in implied volatility. For index options like NIFTY the legs are cash-settled, so there is no delivery obligation — your result is simply the net intrinsic value at expiry minus what you paid.

The numbers that matter

Worked NIFTY example

Suppose NIFTY is near 22,500 and you expect a violent move into expiry, with a bearish lean. You buy two 22,500 puts at ₹120 each and one 22,500 call at ₹120, so the total premium is (2 × 120) + 120 = ₹360. With a lot size of 75, the cost is ₹360 × 75 = ₹27,000 (illustrative figures):

• Upper breakeven: 22,500 + 360 = 22,860 (the single call must recover the whole debit).
• Lower breakeven: 22,500 − (360 ÷ 2) = 22,320 (two puts split the cost).
• Max loss: ₹27,000 if NIFTY expires exactly at 22,500.

NIFTY at expiry	Outcome	P&L (1 lot)
21,500	Two puts deep ITM	+₹1,23,000
22,320 (lower BE)	Puts cover the debit	₹0
22,500 (strike)	All legs worthless	−₹27,000
22,860 (upper BE)	Call covers the debit	₹0
23,500	Single call ITM	+₹48,000

Notice the asymmetry: a 1,000-point fall earns far more than a 1,000-point rally, because two puts work on the way down versus a lone call on the way up. That is the whole point of a strip.

When to use a strip

• You expect a large move but think a fall is the more likely direction.
• A binary event is near — results, RBI policy or global cues — and you want exposure both ways with a downside bias.
• Implied volatility is reasonable, not stretched, so you are not overpaying for the move.
• You want defined risk — the most you can lose is the premium, with no margin call.

Risks to respect

• Time decay: three long options bleed theta every day the market stays calm.
• IV crush: a fall in volatility after an event can sink the position even if the move arrives later.
• The move must be big enough: the underlying has to clear a breakeven, not merely drift, to turn a profit.
• Higher cost than a straddle: the extra put raises the debit, so the move has to be larger to pay off.

Strip vs long straddle

A long straddle buys one call and one put at the same strike for a symmetric V-payoff — neutral on direction. A strip keeps the straddle but adds a second put, tilting the payoff toward a fall. If you are truly direction-agnostic, the straddle is cheaper and balanced; if you lean bearish while still wanting upside cover, the strip earns more on the move you expect.

Strip vs strap

The strip and the strap are mirror images. A strap buys two calls and one put, tilting the payoff toward a rally; a strip buys two puts and one call, tilting it toward a fall. Choose the strap when you expect a big move with a bullish bias, and the strip when you expect a big move with a bearish bias.

Why is it called a “strip”?

The name is old options-floor jargon, paired with its sibling the “strap.” There is no deep story — the two terms simply distinguished the put-heavy version (strip) from the call-heavy version (strap). What matters is the ratio: a strip is always two puts to one call.

Frequently asked questions

Is a strip bullish or bearish?

It is long volatility with a bearish tilt. A strip profits from a big move either way, but because it holds two puts to one call, the downside gain accrues about twice as fast as the upside.

What is the maximum loss on a strip?

The loss is capped at the total premium paid for the two puts and one call. It occurs if the underlying expires exactly at the common strike, leaving every leg worthless.

How is a strip different from a straddle?

A long straddle is one call and one put for a symmetric payoff. A strip adds a second put, so it earns more on a fall while still gaining on a rally.

What happens to a strip if the market stays flat?

If the underlying pins near the strike at expiry, all three legs decay toward zero and you lose most or all of the premium. Theta and falling volatility are the strategy's main enemies.

The bottom line

The strip is the trade for a conviction that a storm is coming and the rain will be heavier than the sunshine. You pay a defined premium, risk no more than that, and get a payoff that pays double on the way down while still rewarding a rally. The catch is the same as any long-volatility trade: the move must be large and reasonably prompt, or theta and IV crush will quietly erode the position. Used around the right catalyst, it is a clean way to express a bearish-but-not-certain view.
