9.2- Strangle (Debit Spread)

The strangle is much like a straddle position, however it requires less capital to initiate the trade. The disadvantage is that a larger move is required in the underlying stock to produce a profit. The strike prices are typically of equal distance apart from the strike price that is closest to the underlying stock price.

The most common time to initiate a strangle is before earnings and before implied volatility has begun to rise in the underlying stock. Because the strangle is Vega positive, an increase in implied volatility will help make the position profitable.

Components:
1) Buy 1 OTM call option
2) Buy 1 OTM put option
(equal strikes apart)

Margin Requirement = Net Debit 

Breakeven on Downside = Put Strike - Net Debit

Breakeven on Upside = Call Strike + Net Debit 

Maximum Loss = Net Debit

Maximum Profit = Unlimited
