In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But the risk of stock picking is that you will likely buy under-performing companies. We regret to report that long term Suzhou Sushi Testing Group Co.,Ltd. (SZSE:300416) shareholders have had that experience, with the share price dropping 40% in three years, versus a market decline of about 19%. And the ride hasn't got any smoother in recent times over the last year, with the price 34% lower in that time. Even worse, it's down 18% in about a month, which isn't fun at all.

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

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.

Although the share price is down over three years, Suzhou Sushi Testing GroupLtd actually managed to grow EPS by 8.0% per year in that time. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Alternatively, growth expectations may have been unreasonable in the past.

It's worth taking a look at other metrics, because the EPS growth doesn't seem to match with the falling share price.

With a rather small yield of just 1.4% we doubt that the stock's share price is based on its dividend. We note that, in three years, revenue has actually grown at a 13% annual rate, so that doesn't seem to be a reason to sell shares. This analysis is just perfunctory, but it might be worth researching Suzhou Sushi Testing GroupLtd more closely, as sometimes stocks fall unfairly. This could present an opportunity.

A Different Perspective

Suzhou Sushi Testing GroupLtd shareholders are down 33% for the year (even including dividends), but the market itself is up 6.1%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 3%, 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. 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.
