We think all investors should try to buy and hold high quality multi-year winners. And highest quality companies can see their share prices grow by huge amounts. Don't believe it? Then look at the Unum Group (NYSE:UNM) share price. It's 494% higher than it was five years ago. And this is just one example of the epic gains achieved by some long term investors. In the last week shares have slid back 1.6%.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

There is no denying that markets are sometimes efficient, but prices do not always reflect 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, Unum Group achieved compound earnings per share (EPS) growth of 14% per year. This EPS growth is slower than the share price growth of 43% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth.

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 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. We note that for Unum Group the TSR over the last 5 years was 627%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

We're pleased to report that Unum Group shareholders have received a total shareholder return of 53% over one year. That's including the dividend. That gain is better than the annual TSR over five years, which is 49%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. It's always interesting to track share price performance over the longer term. But to understand Unum Group better, we need to consider many other factors.
