There's no doubt that investing in the stock market is a truly brilliant way to build wealth. But not every stock you buy will perform as well as the overall market. Unfortunately for shareholders, while the IDACORP, Inc. (NYSE:IDA) share price is up 22% in the last year, that falls short of the market return. The longer term returns have not been as good, with the stock price only 11% higher than it was three years ago.

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.

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).

IDACORP was able to grow EPS by 1.7% in the last twelve months. The share price gain of 22% certainly outpaced the EPS growth. So it's fair to assume the market has a higher opinion of the business than it a year ago.

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 IDACORP the TSR over the last 1 year was 26%, 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

IDACORP provided a TSR of 26% over the last twelve months. But that was short of the market average. The silver lining is that the gain was actually better than the average annual return of 6% per year over five year. It is possible that returns will improve along with the business fundamentals. 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.
