While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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 three years of share price growth, Unum Group achieved compound earnings per share growth of 35% per year. We note that the 44% yearly (average) share price gain isn't too far from the EPS growth rate. Coincidence? Probably not. This observation indicates that the market's attitude to the business hasn't changed all that much. Rather, the share price has approximately tracked EPS 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Unum Group's TSR for the last 3 years was 226%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We're pleased to report that Unum Group shareholders have received a total shareholder return of 65% over one year. And that does include the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 28% per year), it would seem that the stock's performance has improved in recent times. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
