Rongsheng Petrochemical (SZSE:002493) investors are sitting on a loss of 43% if they invested three years ago

For many investors, the main point of stock picking is to generate higher returns than the overall market. But if you try your hand at stock picking, you risk returning less than the market. Unfortunately, that's been the case for longer term Rongsheng Petrochemical Co., Ltd. (SZSE:002493) shareholders, since the share price is down 45% in the last three years, falling well short of the market decline of around 3.1%.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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 five years of share price growth, Rongsheng Petrochemical moved from a loss to profitability. That would generally be considered a positive, so we are surprised to see the share price is down. So it's worth looking at other metrics to try to understand the share price move.

With a rather small yield of just 1.1% 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 20% annual rate, so that doesn't seem to be a reason to sell shares. It's probably worth investigating Rongsheng Petrochemical further; while we may be missing something on this analysis, there might also be an opportunity.

A Different Perspective

Rongsheng Petrochemical shareholders are down 17% for the year (even including dividends), but the market itself is up 15%. 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 6%, 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 Rongsheng Petrochemical better, we need to consider many other factors.
