Thanks for your explanations. I didn't know each contract is 100 shares. That makes sense. 
  
 Another question. If you think a stock will go up, why shouldn't you buy call options? If it goes below your call $, you'll only lose your contract cost. Right?

If you think a stock will go up, you SHOULD buy call options. 
 If the stock price goes below the strike at expiration, the call option is worthless. The most you can lose is what you paid to buy that call option, correct.
