Straddle

The long straddle is the quintessential volatility trade. By purchasing both an ATM call and an ATM put with identical strike prices and expiration dates, the buyer profits if the stock makes a sufficiently large move in either direction. The direction of the move is irrelevant — what matters is magnitude. If the stock is at $100 and you buy the $100 call and $100 put each for $4.00, you pay $800 total. You profit if the stock is above $108 or below $92 at expiration (the strike plus or minus the combined premium).

Long straddles are commonly placed ahead of binary events — earnings announcements, FDA drug rulings, central bank decisions, or geopolitical developments — where a large move is anticipated but the direction is unknown. The risk is that the stock moves less than the combined premium paid, or barely moves at all, leaving the buyer with two options that both decay via theta. This 'theta burn' is the primary cost of the long straddle strategy.

The short straddle takes the opposite position: selling both the ATM call and put, collecting the combined premium and profiting if the stock stays near the strike price. Short straddles are high-risk positions — the maximum loss is theoretically unlimited on the call side and substantial on the put side — but they are profitable in low-volatility, range-bound markets. They are typically used only by experienced traders with robust risk management frameworks, often converted into iron condors by adding protective wings.

Straddles are also used to trade the 'volatility crush' following earnings. Because implied volatility spikes before an earnings announcement and collapses immediately after, short straddle traders positioned before the announcement collect inflated premiums. If the stock's actual move is smaller than the IV-implied expected move, both legs decay and the net credit is retained. Many traders back-test this approach by measuring the historical ratio of actual moves to IV-implied expected moves.

The breakeven analysis of a straddle is straightforward and useful for calibrating position sizing: the implied expected move equals the combined ATM straddle price, providing a quick read on how much the market expects the stock to move.

Long Straddle Before Earnings: Buying a straddle ahead of earnings is the most common use case for the long straddle in U.S. equity markets. The mechanics are appealing: the trader does not need to pick a direction, only correctly predict that the stock will move more than the market-implied expected move. Before entering, calculate the implied move by adding the prices of the ATM call and put; if the straddle costs $6 on a $100 stock, the market implies a 6% move. Back-testing the stock's historical earnings moves against the historically priced-in IV helps identify whether the stock tends to overshoot or undershoot its implied move. Stocks that consistently miss the implied move make better short-straddle candidates; stocks that consistently exceed it favor long-straddle buyers.

Short Straddle: The short straddle is the highest-probability, highest-risk version of the neutral-volatility trade. By selling both the ATM call and ATM put at the same strike, the trader collects the full combined premium as the maximum profit — achieved only if the stock closes exactly at the strike at expiration. The trade profits whenever the stock stays within the combined premium distance of the strike, which covers a wide range but not unlimited stock moves. Because the short straddle has no protective wings, a sharp gap in either direction can produce losses far exceeding the premium collected, making position sizing and active management essential. Many traders convert short straddles into iron condors by purchasing OTM options as wings, accepting a smaller credit in exchange for defined maximum risk.
