What Is a Put?
A put is a bet that a stock falls. You buy the right to sell shares at a set price (the strike) before the contract expires. If the stock drops below that strike, your put gains value. If it stays flat or rises, the put loses value and can expire worthless.
Say SPY is trading at $560. You buy a $555 put for $200. If SPY falls to $550 by expiration, your put is now worth at least $500 (the $5 difference times 100 shares per contract). You sell it, pocket $300 profit. If SPY stays above $555, the put expires worthless and you lose the $200 you paid.
Why use puts? Because sometimes the best trade is the fall. When the Middle East heats up and oil rips 6.2% in a week, tech can bleed. When Meta drops 7% in a day and drags the Nasdaq down 2.6%, puts print. This week Double or Nothing's IWM $270 put doubled for $1,856 profit as small caps absorbed the chaos.
Puts cap your risk at what you paid but let you profit as far down as the stock goes. The catch: time works against you. Every day that passes without the stock falling costs you money as the contract decays. And if you're one strike off — like Double or Nothing's $269 put that lost $3,010 down 93% while the $270 printed — the whipsaw is brutal.
