Long Straddle at expiration
What is this strategy?
The Long Straddle is a volatility-buying strategy that simultaneously buys a put and a call at the same strike price. It is the pure options play for profiting from a large price move: it does not matter whether the market rises or falls, provided it moves significantly from the current strike. It suits situations where you expect high volatility or major announcements capable of causing a significant move.
The structure is simple but powerful: you pay a premium for the call (to profit on the upside) and a premium for the put (to profit on the downside). Maximum loss is capped at the total premiums paid, realised if price expires exactly at the strike. Gains are open-ended in both directions: if price rallies hard the call profits without limit; if it collapses the put profits down to zero.
The Long Straddle requires enough price movement to cover both premiums paid and generate a profit. It is particularly effective ahead of announcements — earnings, central bank decisions — where future volatility is expected. The main challenge is that implied volatility is highest before those events, raising the cost of entry, and realised volatility must exceed implied volatility for the trade to pay.
Construction
| Action | Instrument | Strike | Expiration | Example |
|---|---|---|---|---|
| BUY | 1 Put | ATM | 30-60 DTE | +1 NVDA 140 Put |
| BUY | 1 Call | ATM (same strike) | Same expiry | +1 NVDA 140 Call |
Example
Scenario: NVDA at $140, earnings in 3 weeks. You expect a large move — up or down — after the announcement.
- Call Purchased +1 NVDA 140 Call @ $6.00
- Put Purchased +1 NVDA 140 Put @ $5.50
- Total Debit $1,150 (6.00 + 5.50 × 100)
- Maximum Gain Unlimited (upside) or $12,850 (downside if NVDA → $0)
- Maximum Loss $1,150 (if NVDA = $140 at expiry)
- Breakeven (Upside) $151.50 (140 + 11.50)
- Breakeven (Downside) $128.50 (140 − 11.50)
- Scenario: NVDA at $155 Call worth $1,500, put expires worthless, net profit $350
- Scenario: NVDA at $125 Put worth $1,500, call expires worthless, net profit $350
The Greeks
The long call’s +0.50 delta and the long put’s −0.50 delta cancel perfectly. Completely neutral price exposure at entry.
Theta works against you. Time erodes both options. You bleed daily if price does not move.
Maximum positive volatility exposure. Rises in implied volatility benefit the position significantly.
Gamma is your ally. As price moves in either direction, delta becomes more favourable, accelerating gains.
Position Management
- 01 Sell Quickly After the Event If you opened ahead of an announcement, sell immediately afterwards, since IV drops fast. Do not wait for expiration; IV crush is devastating.
- 02 Take Profits on the Move If price moves significantly in either direction, do not wait for more. Sell the whole straddle. Locked-in gains beat reversal risk.
- 03 Adjust if Needed If price moves strongly one way, you can close the leg that has gone far out of the money and let the winning leg run as an outright call or put.
- 04 Set Loss Limits If price does not move as expected and theta is eating the position — say two or three weeks without movement — close and recover what remains.
- 05 Monitor Volatility Falling IV is your enemy. If you open the straddle and IV drops with no price movement, close early before theta plus IV crush consume the position.
