Kaiser Aluminum's (NASDAQ:KALU) investors will be pleased with their decent 85% return over the last year

Passive investing in index funds can generate returns that roughly match the overall market. But one can do better than that by picking better than average stocks (as part of a diversified portfolio). For example, the Kaiser Aluminum Corporation (NASDAQ:KALU) share price is up 79% in the last 1 year, clearly besting the market return of around 25% (not including dividends). That's a solid performance by our standards! However, the longer term returns haven't been so impressive, with the stock up just 3.1% in the last three years.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

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. 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 Kaiser Aluminum saw its earnings per share (EPS) drop below zero. While this may prove temporary, we'd consider it a negative, so we would not have expected to see the share price up. We might get a clue to explain the share price move by looking to other metrics.

We think that the revenue growth of 15% could have some investors interested. Many businesses do go through a phase where they have to forgo some profits to drive business development, and sometimes its for the best.

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. We note that for Kaiser Aluminum the TSR over the last 1 year was 85%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

It's good to see that Kaiser Aluminum has rewarded shareholders with a total shareholder return of 85% in the last twelve months. And that does include the dividend. That gain is better than the annual TSR over five years, which is 10%. Therefore it seems like sentiment around the company has been positive lately. 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. Consider for instance, the ever-present spectre of investment risk.
