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. For example, we sympathize with anyone who was caught holding Vitasoy International Holdings Limited (HKG:345) during the five years that saw its share price drop a whopping 79%. And it's not just long term holders hurting, because the stock is down 63% in the last year. Shareholders have had an even rougher run lately, with the share price down 34% in the last 90 days.

Since Vitasoy International Holdings has shed HK$793m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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.

Vitasoy International Holdings became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics might give us a better handle on how its value is changing over time.

We don't think that the 0.4% is big factor in the share price, since it's quite small, as dividends go. Arguably, the revenue drop of 4.3% a year for half a decade suggests that the company can't grow in the long term. That could explain the weak share price.

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business. So we recommend checking out this free report showing consensus forecasts

A Different Perspective

We regret to report that Vitasoy International Holdings shareholders are down 63% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 23%. 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 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
