This will confuse you even more...
Have you done some accounting things like NPV, ROI, IRR, EVA, etc? You'll need measures of the economic condition of the company.
If not, get hold of a management acounting book and have a quick read (if that is possible with a book like that). I just had a quick look on Rex's website. You may want to pick a company where you can access an annual shareholders' report.
And don't forget to factor in the price of oil over the next few years and its effect on travel demand. The world is close to peak production and oil costs are expected to rise rapidly as supply dwindles.
Have fun.
