you can buy 100 FB shares for $17,000.00 or you can buy a $180.00 call option for $1.90/share that expires April 20th (at the time of writing, $1.90/share was the quoted market price to purchase this $180.00 call). Your 100-share investment in FB costs you $190.00 plus commission ($1.90 x 100 shares). Now you need FB to go up to over $181.90 per share to break-even on the trade ($180.00 strike price plus the $1.90 you paid for the options on 100 shares).
