### What is an option?

• A stock is like a small portion of a company. If the company does well, the stock foes up. If it does poorly, the stock foes down. For example, suppose you buy one share of Tim Hortons for $10. If lots of people buy coffee, the price might increase to$15 and you make $5. If people stop buying coffee, it might go down to$8 and you lose $2. • Suppose I say to you on May 1, 2010, I will sell you one share of Tim Hortons for$12, regardless of what the market price is, but only if you want. This is a call option, a type of financial derivative.
• If the stock is work $12 on May 1, will you buy the stock from me for$12. What if the stock was worth $8? • How much would you pay me for this call option? That is, the option to buy one share of Tim Hortons for$12 on May 1?
• Options can be on anything that's random: stocks, foreign currencies, oil prices, wheat prices, even weather!
