The total return for IRADIMED (NASDAQ:IRMD) investors has risen faster than earnings growth over the last five years

It hasn't been the best quarter for IRADIMED CORPORATION (NASDAQ:IRMD) shareholders, since the share price has fallen 16% in that time. But that scarcely detracts from the really solid long term returns generated by the company over five years. Indeed, the share price is up an impressive 145% in that time. Generally speaking the long term returns will give you a better idea of business quality than short periods can. Only time will tell if there is still too much optimism currently reflected in the share price.

Although IRADIMED has shed US$61m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

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, IRADIMED achieved compound earnings per share (EPS) growth of 12% per year. This EPS growth is slower than the share price growth of 20% per year, over the same period. This suggests that market participants hold the company in higher regard, these days. And that's hardly shocking given the track record of growth.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for IRADIMED the TSR over the last 5 years was 165%, 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 IRADIMED shareholders have received a total shareholder return of 17% over the last year. And that does include the dividend. However, the TSR over five years, coming in at 21% per year, is even more impressive. Most investors take the time to check the data on insider transactions.
