Insperity's (NYSE:NSP) earnings have declined over three years, contributing to shareholders 58% loss

Insperity, Inc. (NYSE:NSP) shareholders should be happy to see the share price up 22% in the last month. Meanwhile over the last three years the stock has dropped hard. In that time, the share price dropped 61%. So the improvement may be a real relief to some. The rise has some hopeful, but turnarounds are often precarious.

Although the past week has been more reassuring for shareholders, they're still in the red over the last three years, so let's see if the underlying business has been responsible for the decline.

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 way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During the three years that the share price fell, Insperity's earnings per share (EPS) dropped by 51% each year. In comparison the 27% compound annual share price decline isn't as bad as the EPS drop-off. This suggests that the market retains some optimism around long term earnings stability, despite past EPS declines. This positive sentiment is also reflected in the generous P/E ratio of 95.15.

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business. This free interactive report on Insperity's 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 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. In the case of Insperity, it has a TSR of -58% for the last 3 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

Insperity shareholders are down 41% for the year (even including dividends), but the market itself is up 19%. 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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 7% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. It's always interesting to track share price performance over the longer term. But to understand Insperity better, we need to consider many other factors. Consider for instance, the ever-present spectre of investment risk.
