SPY Long Put: the essentials
- Max profit: large but capped: it grows as the stock falls and maxes out if the stock reaches zero (strike minus the premium paid).
- Breakeven: the strike price minus the premium you paid.
- Outlook: bearish — you profit when the stock falls below your breakeven.
Long Put FAQ
Educational overview of how the strategy works — not financial advice.
What is a long put on SPY?
You buy a put on SPDR S&P 500 ETF (SPY) for a premium — the right to sell 100 shares at the strike before expiration. It's a defined-risk bearish bet, or insurance on shares you already own.
How much can I make and lose on a SPY long put?
Loss is capped at the premium paid. Profit grows as SPY falls and maxes out if the stock reached $0: (strike − premium) × 100 — large but capped, unlike an unlimited-risk short.
What is the breakeven on a SPY long put?
The strike price minus the premium you paid. SPY must fall below that by expiration for the put to profit.
Long put vs short-selling SPY?
A put caps your loss at the premium and needs no share borrow or margin, but it decays and expires. Short-selling has theoretically unlimited loss and borrow costs but never expires. The put is the defined-risk way to be bearish or to hedge.
Can I use a SPY put to protect shares I own?
Yes — a "protective put" sets a price floor under your SPDR S&P 500 ETF position for the cost of the premium, like insurance with a deductible (the gap between today's price and the strike). Your downside below the strike is covered; the premium is the cost of that protection.
