The 11% return this week takes Bombardier's (TSE:BBD.B) shareholders three-year gains to 182%

It might seem bad, but the worst that can happen when you buy a stock (without leverage) is that its share price goes to zero. But when you pick a company that is really flourishing, you can make more than 100%. For example, the Bombardier Inc. (TSE:BBD.B) share price has soared 182% in the last three years. How nice for those who held the stock! On top of that, the share price is up 68% in about a quarter.

Since the stock has added CA$964m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

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

You can see how EPS has changed over time in the image below (click on the chart to see the exact values).

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money.

A Different Perspective

It's nice to see that Bombardier shareholders have received a total shareholder return of 66% over the last year. That's better than the annualised return of 13% over half a decade, implying that the company is doing better recently. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Case in point: We've spotted 5 warning signs for Bombardier you should be aware of, and 2 of them can't be ignored.
