In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. We regret to report that long term OMH SCIENCE Group Co., Ltd (SZSE:300486) shareholders have had that experience, with the share price dropping 43% in three years, versus a market decline of about 13%. And more recent buyers are having a tough time too, with a drop of 21% in the last year. Furthermore, it's down 23% in about a quarter. That's not much fun for holders. Of course, this share price action may well have been influenced by the 12% decline in the broader market, throughout the period.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

A Different Perspective

We regret to report that OMH SCIENCE Group shareholders are down 21% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 6.4%. 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. Longer term investors wouldn't be so upset, since they would have made 5%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. It's always interesting to track share price performance over the longer term. But to understand OMH SCIENCE Group better, we need to consider many other factors.
