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. For instance, the price of TransDigm Group Incorporated (NYSE:TDG) stock is up an impressive 123% over the last five years. In the last week shares have slid back 7.1%.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Over half a decade, TransDigm Group managed to grow its earnings per share at 16% a year. This EPS growth is reasonably close to the 17% average annual increase in the share price. This indicates that investor sentiment towards the company has not changed a great deal. Rather, the share price has approximately tracked EPS growth.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for TransDigm Group the TSR over the last 5 years was 166%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's nice to see that TransDigm Group shareholders have received a total shareholder return of 43% over the last year. That's including the dividend. That's better than the annualised return of 22% over half a decade, implying that the company is doing better recently. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
