The five-year decline in earnings might be taking its toll on Lundin Mining (TSE:LUN) shareholders as stock falls 5.9% over the past week

Lundin Mining Corporation (TSE:LUN) shareholders might be concerned after seeing the share price drop 17% in the last month. But that scarcely detracts from the really solid long term returns generated by the company over five years. We think most investors would be happy with the 105% return, over that period. We think it's more important to dwell on the long term returns than the short term returns. Only time will tell if there is still too much optimism currently reflected in the share price.

Although Lundin Mining has shed CA$708m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

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...' One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During five years of share price growth, Lundin Mining actually saw its EPS drop 9.2% per year.

Essentially, it doesn't seem likely that investors are focused on EPS. Because earnings per share don't seem to match up with the share price, we'll take a look at other metrics instead.

On the other hand, Lundin Mining's revenue is growing nicely, at a compound rate of 15% over the last five years. It's quite possible that management are prioritizing revenue growth over EPS growth at the moment.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

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. In the case of Lundin Mining, it has a TSR of 142% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We're pleased to report that Lundin Mining shareholders have received a total shareholder return of 37% over one year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 19% 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. 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.
