Integral Diagnostics (ASX:IDX) shareholders have endured a 41% loss from investing in the stock a year ago

The simplest way to benefit from a rising market is to buy an index fund. When you buy individual stocks, you can make higher profits, but you also face the risk of under-performance. Investors in Integral Diagnostics Limited (ASX:IDX) have tasted that bitter downside in the last year, as the share price dropped 43%. That's well below the market decline of 2.2%. Longer term shareholders haven't suffered as badly, since the stock is down a comparatively less painful 24% in three years.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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.

Unhappily, Integral Diagnostics had to report a 56% decline in EPS over the last year. This fall in the EPS is significantly worse than the 43% the share price fall. So despite the weak per-share profits, some investors are probably relieved the situation wasn't more difficult.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money. This free interactive report on Integral Diagnostics' earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Integral Diagnostics the TSR over the last 1 year was -41%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Investors in Integral Diagnostics had a tough year, with a total loss of 41% (including dividends), against a market gain of about 2.2%. 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. On the bright side, long term shareholders have made money, with a gain of 7% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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. Take risks, for example - Integral Diagnostics has 3 warning signs (and 1 which shouldn't be ignored) we think you should know about.
