When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. For example, the ArcBest Corporation (NASDAQ:ARCB) share price has soared 238% in the last half decade. Most would be very happy with that. Better yet, the share price has risen 4.8% in the last week. But this could be related to the buoyant market which is up about 4.2% in a week.

Since the stock has added US$112m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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 five years of share price growth, ArcBest achieved compound earnings per share (EPS) growth of 10% per year. This EPS growth is slower than the share price growth of 28% per year, over the same period. This suggests that market participants hold the company in higher regard, these days. That's not necessarily surprising considering the five-year track record of earnings growth.

The graphic below depicts how EPS has changed over time (unveil the exact values by clicking on the image).

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. This free interactive report on ArcBest's earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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 ArcBest the TSR over the last 5 years was 249%, 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

ArcBest provided a TSR of 2.3% over the last twelve months. But that return falls short of the market. It's probably a good sign that the company has an even better long term track record, having provided shareholders with an annual TSR of 28% over five years. Maybe the share price is just taking a breather while the business executes on its growth strategy.
