This week we saw the Hua Hong Semiconductor Limited (HKG:1347) share price climb by 17%. Meanwhile over the last three years the stock has dropped hard. In that time, the share price dropped 53%. So the improvement may be a real relief to some. After all, could be that the fall was overdone.

Although the past week has been more reassuring for shareholders, they're still in the red over the last three years, so let's see if the underlying business has been responsible for the decline.

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.

During the three years that the share price fell, Hua Hong Semiconductor's earnings per share (EPS) dropped by 22% each year. The 22% average annual share price decline is remarkably close to the EPS decline. So it seems that investor expectations of the company are staying pretty steady, despite the disappointment. It seems like the share price is reflecting the declining earnings per share.

A Different Perspective

Hua Hong Semiconductor shareholders are down 3.3% for the year (even including dividends), but the market itself is up 19%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 4% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
