While it may not be enough for some shareholders, we think it is good to see the Luoniushan Co., Ltd. (SZSE:000735) share price up 13% in a single quarter. But that doesn't change the fact that the returns over the last five years have been less than pleasing. In fact, the share price is down 45%, which falls well short of the return you could get by buying an index fund.

Although the past week has been more reassuring for shareholders, they're still in the red over the last five 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. 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.

Over five years Luoniushan's earnings per share dropped significantly, falling to a loss, with the share price also lower. At present it's hard to make valid comparisons between EPS and the share price. But we would generally expect a lower price, given the situation.

A Different Perspective

We regret to report that Luoniushan shareholders are down 25% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 17%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 8% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. 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.
