NEW YORK ( F.A.S.T. Graphs) -- Recently, I happened upon an excerpt of TheStreet.com founder Jim Cramer's CNBC show "Mad Money." Specifically, I'm referencing the "Lightning Round" segment on Aug. 26.The first question was about Nike ( NKE), to which Cramer replied: "I like Nike. I like Under Armour even better." Now, the second bit about Under Armour ( UA) might very well be true, but I'd like to investigate the Nike comment a touch more. I'm guessing Cramer and I share a similar view on this subject, but I also believe that it's important to decipher the difference between a good company and a good investment. Just because someone says they like or don't like something doesn't mean that you can substitute that for proper due diligence. It's always good to double-check what you're hearing. Even within this article, there are many more items that you would probably want to investigate. The first thing that I would check when looking into Nike is the company's business results. F.A.S.T. Graphs. Here we see that Nike was able to grow earnings by about 13% a year (orange line). In addition, we can also see that dividends (pink line and blue shaded area) have begun to increase at a steady rate.
