It's been a soft week for Spok Holdings, Inc. (NASDAQ:SPOK) shares, which are down 14%. While that might be a setback, it doesn't negate the nice returns received over the last twelve months. After all, the share price is up a market-beating 92% in that time.

While this past week has detracted from the company's one-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. 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.

Spok Holdings went from making a loss to reporting a profit, in the last year.

When a company is just on the edge of profitability it can be well worth considering other metrics in order to more precisely gauge growth (and therefore understand share price movements).

We haven't seen Spok Holdings increase dividend payments yet, so the yield probably hasn't helped drive the share higher. And at a glance the revenue growth does not impress, though a closer look at revenue trends may reveal some form of insight.

It's good to see that there was some significant insider buying in the last three months. That's a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business. So it makes a lot of sense to check out what analysts think Spok Holdings will earn in the future (free profit forecasts).

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. As it happens, Spok Holdings' TSR for the last 1 year was 111%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's good to see that Spok Holdings has rewarded shareholders with a total shareholder return of 111% in the last twelve months. Of course, that includes the dividend. That's better than the annualised return of 10% over half a decade, implying that the company is doing better recently. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
