When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But when you pick a company that is really flourishing, you can make more than 100%. Long term Blue Bird Corporation (NASDAQ:BLBD) shareholders would be well aware of this, since the stock is up 104% in five years. On top of that, the share price is up 36% in about a quarter.

Since it's been a strong week for Blue Bird shareholders, let's have a look at trend of the longer term fundamentals.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During the last half decade, Blue Bird became profitable. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

It is of course excellent to see how Blue Bird has grown profits over the years, but the future is more important for shareholders. You can see how its balance sheet has strengthened (or weakened) over time in this free interactive graphic.

A Different Perspective

We're pleased to report that Blue Bird shareholders have received a total shareholder return of 79% over one year. That gain is better than the annual TSR over five years, which is 15%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
