Long Straddle
Buy ATM call + buy ATM put — pure long volatility
What is Long Straddle?
Long Straddle A long straddle is a defined-risk volatility-buying strategy that combines a long at-the-money call with a long at-the-money put at the same strike price and expiration. The position profits when the underlying makes a large move in either direction. Maximum loss is the total premium paid (both legs); maximum profit is theoretically unlimited (call side) or large (put side, bounded by stock-to-zero). Structure: - Buy 1 ATM call - Buy 1 ATM put (same strike, same expiration) - Net cost: total of both premiums (typically 1.5-2× a same-DTE OTM strangle) The long straddle is the cleanest volatility play — pure vega exposure with no directional bias. It's the most expensive single-event volatility trade but offers the narrowest breakeven distance. Worked example: AAPL at $185, 30 DTE - Buy 1 AAPL $185C for $4.50 - Buy 1 AAPL $185P for $4.50 - Total debit: $9.00 ($900 per contract) - Upper breakeven: $185 + $9 = $194 (+4.9% move) - Lower breakeven: $185 − $9 = $176 (-4.9% move) - Max loss: $900 if AAPL closes exactly at $185 at expiration - Max profit: unlimited above $194 or below $176 Compared to the equivalent strangle (e.g., $190/$180 wings at $4.70 total), the straddle costs $9.00 — nearly 2× the strangle's cost. But the straddle only needs a 4.9% move to break even, while the strangle needs an 8% move. When to use long straddles: - **Pre-event positioning with high conviction of large move**: when you expect not just a move, but a meaningful one. The straddle's narrower breakevens reward smaller moves than the strangle. - **Vol-expansion plays**: long straddles are vega-positive and benefit from rising IV even without underlying movement. ATM straddles have the highest vega per dollar of premium. - **Earnings positioning when implied move is below historical moves**: rare but valuable setups where the market is underpricing the volatility. Earnings straddle trap: the most common misuse of long straddles is buying them into earnings expecting a directional surprise. In practice, IV crush after earnings consistently overwhelms the realized directional move, making systematic earnings straddle buying a losing strategy across multi-quarter samples. Long straddles work best when you specifically expect the actual move to *exceed* the implied move — not just to confirm direction. Gamma scalping with long straddles: professional traders open long straddles in low-IV environments and dynamically delta-hedge by trading the underlying as it moves. Profits come from realized volatility exceeding implied volatility, harvested through the back-and-forth movement of the underlying. The long-straddle gamma is the central engine of this strategy.

Example
TSLA at $250 pre-earnings, IV rank 35 (moderate). Buy 1 $250 straddle for $18.00. After earnings, TSLA gaps to $278 (+11%). Call worth $28, put worth $0.30. Close for $28.30 credit. Net profit: +$1,030 (57% return on $1,800 debit).

Frequently Asked Questions
What is a long straddle?
A long straddle is buying an ATM call plus an ATM put at the same strike and expiration. It profits from large moves in either direction. Maximum loss is the total premium paid; maximum profit is unlimited above the upper breakeven or large below the lower breakeven.
How much does a long straddle cost?
Typically 1.5-2× the cost of an equivalent OTM strangle. ATM options carry the highest extrinsic value, so straddles are the most expensive single-event volatility trades. For a $185 AAPL straddle at 30 DTE, expect $8-10 in premium per share ($800-1,000 per contract).
Why do most long straddles lose money?
Systematic earnings-event straddle buying loses across multi-quarter samples because IV crush after the event typically exceeds the realized directional move. Long straddles work best when you specifically expect realized vol to exceed implied vol — not just to confirm direction.
