Shareholders in Westlake (NYSE:WLK) are in the red if they invested a year ago

While not a mind-blowing move, it is good to see that the Westlake Corporation (NYSE:WLK) share price has gained 18% in the last three months. But that is minimal compensation for the share price under-performance over the last year. After all, the share price is down 38% in the last year, significantly under-performing the market.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

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 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.

Westlake fell to a loss making position during the year. While this may prove temporary, we'd consider it a negative, so it doesn't surprise us that the stock price is down. We hope for shareholders' sake that the company becomes profitable again soon.

A Different Perspective

Westlake shareholders are down 37% for the year (even including dividends), but the market itself is up 20%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 8% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. It's always interesting to track share price performance over the longer term. But to understand Westlake better, we need to consider many other factors.
