For many, the main point of investing is to generate higher returns than the overall market. But in any portfolio, there will be mixed results between individual stocks. At this point some shareholders may be questioning their investment in American Assets Trust, Inc. (NYSE:AAT), since the last five years saw the share price fall 38%.

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.

View our latest analysis for American Assets Trust

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).

While the share price declined over five years, American Assets Trust actually managed to increase EPS by an average of 4.3% per year. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Alternatively, growth expectations may have been unreasonable in the past.

Based on these numbers, we'd venture that the market may have been over-optimistic about forecast growth, half a decade ago. Looking to other metrics might better explain the share price change.

We note that the dividend has remained healthy, so that wouldn't really explain the share price drop. It's not immediately clear to us why the stock price is down but further research might provide some answers.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. As it happens, American Assets Trust's TSR for the last 5 years was -22%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

American Assets Trust's TSR for the year was broadly in line with the market average, at 36%. The silver lining is that the share price is up in the short term, which flies in the face of the annualised loss of 4% over the last five years. We're pretty skeptical of turnaround stories, but it's good to see the recent share price recovery. 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.
