Long Straddle

A long straddle involves buying both a call and a put option on the same underlying asset, with identical strike prices and expiration dates. This strategy is particularly useful when you anticipate significant volatility in the asset’s price but are uncertain about the direction of the move. Mechanics:

Purchase a Call Option

This gives you the right, but not the obligation, to buy the underlying asset at the strike price.

Purchase a Put Option

This gives you the right, but not the obligation, to sell the underlying asset at the strike price.

Same Strike Price and Expiration

Both options must have the same strike price and expiration date to form a straddle.

Theoretically, the call option offers unlimited profit potential if the underlying asset’s price skyrockets. The put option provides significant profit potential if the asset’s price plummets. The maximum loss is confined to the total premium paid for both options. This occurs if the asset’s price remains stagnant at the strike price at expiration.

To calculate the break-even points, you need to account for the total premium paid:

Upper Break-Even Point

$\text{Strike Price}+\text{Total Premium Paid}$

Lower Break-Even Point

$\text{Strike Price}-\text{Total Premium Paid}$

Suppose you buy a call and a put option on Stock XYZ, both with a strike price of $100 and a premium of $5 each. The total premium paid is $10.

Upper Break-Even

$100+10=110$

Lower Break-Even

$100-10=90$

You start making a profit if the stock price moves beyond $110 or below $90. This makes it ideal in highly volatile markets or when significant news events are expected. You benefit from significant price movements in either direction and your maximum loss is limited to the total premium paid.

The entry test is the one from the strategy primer at the top of this chapter, and it is the only one that matters: a long straddle makes money when realized volatility beats the implied volatility you paid for — not when the move is merely large. The breakevens make the bar concrete. In the example, $10 of premium on a $100 stock means the chain is pricing a 10% move; your thesis has to be that the market’s number is too low. Around a known event — earnings, an FDA decision, a verdict — implied volatility inflates in advance and collapses the moment the news prints, so a straddle bought the day before earnings can lose money on a 7% move it correctly predicted. Before concluding you know something the option chain does not, compare the straddle’s implied move against what the stock actually did on its last several comparable events.

Time works against you twice: theta erodes both legs, and it erodes fastest near expiration for at-the-money options — which is exactly what a straddle is made of. Buy more time than the move needs, and take the position off once the move has happened instead of riding the surviving leg to expiry.
