Shareholders in STMicroelectronics (EPA:STMPA) are in the red if they invested three years ago
As an investor its worth striving to ensure your overall portfolio beats the market average. But the risk of stock picking is that you will likely buy under-performing companies. Unfortunately, that's been the case for longer term STMicroelectronics N.V. (EPA:STMPA) shareholders, since the share price is down 37% in the last three years, falling well short of the market return of around 20%.
So let's have a look 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 three years that the share price fell, STMicroelectronics' earnings per share (EPS) dropped by 46% each year. In comparison the 14% compound annual share price decline isn't as bad as the EPS drop-off. So, despite the prior disappointment, shareholders must have some confidence the situation will improve, longer term.

However, the loss over the last year isn't as bad as the 5% per annum loss investors have suffered over the last half decade. We would want clear information suggesting the company will grow, before taking the view that the share price will stabilize. 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.
