Tower Semiconductor Ltd. (NASDAQ:TSEM) shareholders might understandably be very concerned that the share price has dropped 43% in the last quarter. On the bright side the share price is up over the last half decade. However we are not very impressed because the share price is only up 70%, less than the market return of 95%.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

There is no denying that markets are sometimes efficient, but prices do not always reflect 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.

Over half a decade, Tower Semiconductor managed to grow its earnings per share at 17% a year. This EPS growth is higher than the 11% average annual increase in the share price. So it seems the market isn't so enthusiastic about the stock these days.

A Different Perspective

We regret to report that Tower Semiconductor shareholders are down 9.2% for the year. Unfortunately, that's worse than the broader market decline of 1.9%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. On the bright side, long term shareholders have made money, with a gain of 11% 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. 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.
