While not a mind-blowing move, it is good to see that the Integral Diagnostics Limited (ASX:IDX) share price has gained 27% in the last three months. But that cannot eclipse the less-than-impressive returns over the last three years. Truth be told the share price declined 45% in three years and that return, Dear Reader, falls short of what you could have got from passive investing with an index fund.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

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...' By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Over the three years that the share price declined, Integral Diagnostics' earnings per share (EPS) dropped significantly, falling to a loss. This was, in part, due to extraordinary items impacting earnings. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. However, we can say we'd expect to see a falling share price in this scenario.

We like that insiders have been buying shares in the last twelve months. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Integral Diagnostics' TSR for the last 3 years was -40%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Integral Diagnostics shareholders are down 17% for the year (even including dividends), but the market itself is up 10.0%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 0.9% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. It's always interesting to track share price performance over the longer term. But to understand Integral Diagnostics better, we need to consider many other factors.
