Check out our latest analysis for SAM Engineering & Equipment (M) Berhad

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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 three years of share price growth, SAM Engineering & Equipment (M) Berhad achieved compound earnings per share growth of 13% per year. In comparison, the 35% per year gain in the share price outpaces the EPS growth. So it's fair to assume the market has a higher opinion of the business than it did three years ago. That's not necessarily surprising considering the three-year track record of earnings growth.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for SAM Engineering & Equipment (M) Berhad the TSR over the last 3 years was 154%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

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.
