Straddle
Options strategy that profits from a large move in either direction when volatility matters more than direction.
A straddle is an options strategy that combines a call and a put on the same underlying asset, with the same strike price and expiration date. The most common default meaning is a long straddle, where the trader buys both options.
Why It Matters
A straddle matters because it lets a trader express a view on movement rather than direction.
It is commonly used when the trader believes:
-
volatility may be high
-
a major event is coming
-
the market may move sharply but the direction is uncertain
How It Works in Finance Practice
In a long straddle, the trader buys:
-
a call option
-
a put option
Both contracts share the same strike and expiration. The total cost is the sum of the two premiums.
At expiration, the position needs a large enough move away from the strike to overcome both premiums paid.
Long straddles are often discussed alongside implied volatility, because buying two options can be expensive when the market already expects a large move.
Practical Example
Suppose a stock is trading at $100.
A trader buys:
-
a
$100call for$5 -
a
$100put for$5
The total cost is $10. The trade generally needs the stock to finish above $110 or below $90 at expiration to produce intrinsic-value profit that exceeds the premium paid.
Straddle is not the same as strangle
A strangle uses different strike prices and is usually cheaper but requires a larger move to work.
A straddle can lose even when the stock moves
If the move is smaller than the market already priced in, or if implied volatility collapses after an event, the trade can disappoint.
“Straddle” usually means long straddle in educational shorthand
There is also a short straddle, which profits from stability but carries very different risk.
