While shareholders of Blue Bird (NASDAQ:BLBD) are in the black over 3 years, those who bought a week ago aren't so fortunate

Generally speaking, investors are inspired to be stock pickers by the potential to find the big winners. Mistakes are inevitable, but a single top stock pick can cover any losses, and so much more. Take, for example, the Blue Bird Corporation (NASDAQ:BLBD) share price, which skyrocketed 327% over three years. On top of that, the share price is up 27% in about a quarter. But this could be related to the strong market, which is up 20% in the last three months.

Although Blue Bird has shed US$83m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During three years of share price growth, Blue Bird moved from a loss to profitability. Given the importance of this milestone, it's not overly surprising that the share price has increased strongly.

A Different Perspective

While the broader market gained around 16% in the last year, Blue Bird shareholders lost 15%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 27%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering.
