Straddle
type of stock options trading strategy where two financial transactions share the same security, with positions that offset one another
In finance, a straddle strategy involves two transactions in options on the same underlying, with opposite positions. One holds long risk, the other short. As a result, it involves the purchase or sale of particular option derivatives that allow the holder to profit based on how much the price of the underlying security moves, regardless of the direction of price movement.
A straddle involves buying a call and put with same strike price and expiration date in the same notional amounts. If the stock price is close to the strike price at expiration of the options, the straddle leads to a loss. However, if there is a sufficiently large move in either direction, a significant profit will result. A straddle is appropriate when an investor is expecting a large move in a stock price but does not know in which direction the move will be.
A straddle made from the purchase of options is known as a long straddle, bottom straddle, or straddle purchase, while the reverse position, made from the sale of the options, is known as a short straddle, top straddle, or straddle write.
Long straddle
A long straddle involves "going long volatility", in other words purchasing both a call option and a put option on some stock, interest rate, index or other underlying. The two options are bought at the same strike price and expire at the same time.

Why this record matters
“Straddle” is worth following because a concise public description often conceals a longer documentary argument. Here, Straddle, type and stock provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 5, 2026. The linked authority identifier is Q1406345. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
