The simplest way to invest in stocks is to buy exchange traded funds. But one can do better than that by picking better than average stocks (as part of a diversified portfolio). For example, the MGE Energy, Inc. (NASDAQ:MGEE) share price is up 32% in the last 1 year, clearly besting the market return of around 23% (not including dividends). That's a solid performance by our standards! The longer term returns have not been as good, with the stock price only 19% 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.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the last year, MGE Energy actually saw its earnings per share drop 0.06%.

We don't think that the decline in earnings per share is a good measure of the business over the last twelve months. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

We are skeptical of the suggestion that the 1.9% dividend yield would entice buyers to the stock. Unfortunately MGE Energy's fell 6.7% over twelve months. So using a snapshot of key business metrics doesn't give us a good picture of why the market is bidding up the stock.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of MGE Energy, it has a TSR of 35% for the last 1 year. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that MGE Energy shareholders have received a total shareholder return of 35% over one year. That's including the dividend. That's better than the annualised return of 6% over half a decade, implying that the company is doing better recently. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
