Investors in TransDigm Group (NYSE:TDG) have seen enviable returns of 324% over the past five years

When you buy a stock there is always a possibility that it could drop 100%. But on a lighter note, a good company can see its share price rise well over 100%. One great example is TransDigm Group Incorporated (NYSE:TDG) which saw its share price drive 277% higher over five years. It's also good to see the share price up 22% over the last quarter. But this could be related to the strong market, which is up 23% in the last three months.

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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 19% per year. This EPS growth is slower than the share price growth of 30% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth. This optimism is visible in its fairly high P/E ratio of 52.16.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, TransDigm Group's TSR for the last 5 years was 324%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that TransDigm Group shareholders have received a total shareholder return of 34% over one year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 33% per year), it would seem that the stock's performance has improved in recent times. 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.
