Options: Leverage + Defined Risk
Buy 1 contract · strike $100 · $3
You pay $3 per share ($300 for one 100-share contract) to control 100 shares of a $100 stock. Pick a direction and drag where the stock lands at expiry:
Stock price at expiry$110
your profit / loss
return on $300
Max loss is the premium — always. That "defined risk" plus the leverage is why options can trade any market on the map without betting the whole account.
