8.2% earnings growth over 3 years has not materialized into gains for Ningbo BaoSi Energy Equipment (SZSE:300441) shareholders over that period

Many investors define successful investing as beating the market average over the long term. But the risk of stock picking is that you will likely buy under-performing companies. We regret to report that long term Ningbo BaoSi Energy Equipment Co., Ltd. (SZSE:300441) shareholders have had that experience, with the share price dropping 44% in three years, versus a market decline of about 23%. More recently, the share price has dropped a further 18% in a month.

Since Ningbo BaoSi Energy Equipment has shed CN¥428m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Although the share price is down over three years, Ningbo BaoSi Energy Equipment actually managed to grow EPS by 27% 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). Or else the company was over-hyped in the past, and so its growth has disappointed.

Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

With a rather small yield of just 1.2% we doubt that the stock's share price is based on its dividend. The company has kept revenue pretty healthy over the last three years, so we doubt that explains the falling share price. We're not entirely sure why the share price is dropped, but it does seem likely investors have become less optimistic about the business.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Ningbo BaoSi Energy Equipment, it has a TSR of -41% for the last 3 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's nice to see that Ningbo BaoSi Energy Equipment shareholders have received a total shareholder return of 10.0% over the last year. And that does include the dividend. Notably the five-year annualised TSR loss of 5% per year compares very unfavourably with the recent share price performance. We generally put more weight on the long term performance over the short term, but the recent improvement could hint at a (positive) inflection point within the business. 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. Consider for instance, the ever-present spectre of investment risk.
