If you think NVDA is going to fall, you could “Short” 100 shares. But shorting is incredibly risky:

• Unlimited Risk: If NVDA surprises the market and shoots up, your losses are theoretically infinite.

• High Capital: You need a massive margin account to short shares.

The Long Put Solution: By buying a Put option, you have the Right, but not the Obligation to sell the stock at a fixed price.

• If the stock crashes: Your put value explodes.

• If the stock moonshots: You simply let the option expire. The most you can lose is the small fee you paid.
