I bought 3 call options (equivalent to 300 shares) in Starbucks with a Jan 2010 strike price of $15 for $4 a share in Apr 2008. The stock was trading at around $14.50 when I bought the call options. I just sold the call options (yesterday) at $4.85 a share for a 21.25% gain.
You can make or lose money quickly in options. I remember that within the first 30 days I was up over 20%. Unfortunately, I never cashed out early and held the options for a lot of ups and downs.
Had I bought the call options in March of this year I would be up far more. That's ok. At least now I'm developing some initial confidence in options trading.
