Changzhou Langbo Sealing TechnologiesLtd's (SHSE:603655) earnings trajectory could turn positive as the stock pops 11% this past week

It's nice to see the Changzhou Langbo Sealing Technologies Co.,Ltd. (SHSE:603655) share price up 11% in a week. But over the last three years we've seen a quite serious decline. Indeed, the share price is down a tragic 52% in the last three years. So the improvement may be a real relief to some. While many would remain nervous, there could be further gains if the business can put its best foot forward.

On a more encouraging note the company has added CN¥144m to its market cap in just the last 7 days, so let's see if we can determine what's driven the three-year loss for shareholders.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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.

Changzhou Langbo Sealing TechnologiesLtd saw its EPS decline at a compound rate of 2.1% per year, over the last three years. The share price decline of 22% is actually steeper than the EPS slippage. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy. Of course, with a P/E ratio of 58.25, the market remains optimistic.

A Different Perspective

While the broader market lost about 14% in the twelve months, Changzhou Langbo Sealing TechnologiesLtd shareholders did even worse, losing 38% (even including dividends). 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 3% 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.
