Long term investing works well, but it doesn't always work for each individual stock. We really hate to see fellow investors lose their hard-earned money. Anyone who held Zhejiang Unifull Industrial Fibre Co., Ltd. (SZSE:002427) for five years would be nursing their metaphorical wounds since the share price dropped 79% in that time. And it's not just long term holders hurting, because the stock is down 52% in the last year. Shareholders have had an even rougher run lately, with the share price down 31% in the last 90 days.

If the past week is anything to go by, investor sentiment for Zhejiang Unifull Industrial Fibre 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.

Zhejiang Unifull Industrial Fibre became profitable within the last five years. Most would consider that to be a good thing, so it's counter-intuitive to see the share price declining. Other metrics might give us a better handle on how its value is changing over time.

It could be that the revenue decline of 9.5% per year is viewed as evidence that Zhejiang Unifull Industrial Fibre is shrinking. This has probably encouraged some shareholders to sell down the stock.

A Different Perspective

We regret to report that Zhejiang Unifull Industrial Fibre shareholders are down 52% for the year. 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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 12% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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.
