Straddle
A straddle buys a call and a put at the same strike, profiting from a big move in either direction. Learn how it works and why the size of the move is all that matters.
A straddle is buying a call and a put at the same strike and expiration. It profits when the stock makes a big move, up or down, it does not matter which. You are not betting on direction. You are betting that the stock will not sit still.
It is the go-to trade when you know something big is coming but have no idea which way it breaks. Let me show you.
Betting on the Size, Not the Direction
Imagine a big verdict is about to drop in a court case, and you know the stock will lurch hard afterward. You just do not know if the news will be good or bad. Betting on direction is a coin flip. But betting that the stock moves a lot is a much safer read.
A straddle lets you make exactly that bet. You buy a call (which wins if the stock jumps up) and a put (which wins if it drops) at the same strike. Whichever way the stock explodes, one side pays off big. You only lose if the stock barely moves.
Watch It Work
Apple is at $200, earnings are tomorrow, and you expect a big reaction. You buy a straddle:
- Buy the $200 call for $5 a share
- Buy the $200 put for $5 a share
- Total cost: $10 a share, or $1,000
That $1,000 is your total risk. Because you paid $10 in premium, the stock has to move more than $10 in either direction to profit. Your break-evens are $210 up and $190 down.
Apple jumps to $225. Your call is worth $25 a share. After the $10 total cost, you keep $15 a share, or $1,500. The put expired worthless, but the call more than paid for both.
Apple crashes to $175. Your put is worth $25 a share. Same result: $1,500 profit, this time from the put side.
Apple sits at $200. Both options expire near worthless. You lose most of your $1,000. This is the trap: a straddle needs a real move to win.
The Catch: You Are Fighting Two Forces
A straddle is powerful, but two things work against you.
Cost. You are buying two options, so it is expensive. The stock must move more than the combined premium just to break even.
Volatility crush. Straddles are often bought before events like earnings, when implied volatility is high and options are pricey. Right after the event, volatility collapses in an IV crush. If the stock does not move enough, both your options lose value fast, even if you were roughly right that "something" would happen.
So a straddle needs a move that is big enough to beat both the premium you paid and the volatility drop that follows. That is a higher bar than it first appears.
- A straddle buys a call and a put at the same strike.
- It profits from a big move in either direction, not on direction.
- It loses if the stock barely moves; the move must beat both premiums.
- Watch out for IV crush after the event you bought it for.

Three quick questions to see what stuck. Pick an answer and the explanation shows up right away.
What is a straddle betting on?
A straddle profits from a large move up or down. Direction does not matter, only the size of the move.
You pay $10 total for a $200 straddle. What are your break-evens?
The stock must move more than the $10 premium either way, so break-evens are $210 up and $190 down.
What often works against a straddle bought before earnings?
You buy when volatility is high, and it collapses after the event. The move must beat both the premium and that IV crush.
Bottom Line
A straddle is a bet on motion. Buy a call and a put at the same strike, and a big move in either direction pays off. Your only losing case is a stock that sits still. The costs are real, though: two premiums to pay and an IV crush that often follows the very event you were betting on.
Reach for a straddle when you are confident a stock is about to move hard but genuinely cannot tell which way. Just make sure the expected move is big enough to clear both hurdles.
Keep going: the cheaper, wider cousin is the strangle, and the risk to watch is IV crush.
