The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on the bright side, you can make far more than 100% on a really good stock. Long term TransDigm Group Incorporated (NYSE:TDG) shareholders would be well aware of this, since the stock is up 120% in five years. On the other hand, we note it's down 9.3% in about a month.

While the stock has fallen 4.7% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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 five years of share price growth, TransDigm Group achieved compound earnings per share (EPS) growth of 15% per year. So the EPS growth rate is rather close to the annualized share price gain of 17% per year. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. Rather, the share price has approximately tracked EPS growth.

It is of course excellent to see how TransDigm Group 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.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of TransDigm Group, it has a TSR of 162% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

TransDigm Group shareholders have received returns of 30% over twelve months (even including dividends), which isn't far from the general market return. That gain looks pretty satisfying, and it is even better than the five-year TSR of 21% per year. Even if the share price growth slows down from here, there's a good chance that this is business worth watching in the long term. 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.
