47% earnings growth over 1 year has not materialized into gains for Changzhou Langbo Sealing TechnologiesLtd (SHSE:603655) shareholders over that period

It's easy to match the overall market return by buying an index fund. But if you buy individual stocks, you can do both better or worse than that. That downside risk was realized by Changzhou Langbo Sealing Technologies Co.,Ltd. (SHSE:603655) shareholders over the last year, as the share price declined 42%. That's disappointing when you consider the market declined 12%. Notably, shareholders had a tough run over the longer term, too, with a drop of 36% in the last three years. On top of that, the share price is down 12% in the last week.

If the past week is anything to go by, investor sentiment for Changzhou Langbo Sealing TechnologiesLtd isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

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.

During the unfortunate twelve months during which the Changzhou Langbo Sealing TechnologiesLtd share price fell, it actually saw its earnings per share (EPS) improve by 47%. It's quite possible that growth expectations may have been unreasonable in the past.

The divergence between the EPS and the share price is quite notable, during the year. So it's easy to justify a look at some other metrics.

With a low yield of 0.5% we doubt that the dividend influences the share price much. Changzhou Langbo Sealing TechnologiesLtd managed to grow revenue over the last year, which is usually a real positive. Since the fundamental metrics don't readily explain the share price drop, there might be an opportunity if the market has overreacted.

A Different Perspective

While the broader market lost about 12% in the twelve months, Changzhou Langbo Sealing TechnologiesLtd shareholders did even worse, losing 41% (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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 3% over the last half decade. 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.
