The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on the bright side, you can make far more than 100% on a really good stock. For example, the Shanghai Yanhua Smartech Group Co., Ltd. (SZSE:002178) share price has soared 119% in the last half decade. Most would be very happy with that. On top of that, the share price is up 106% in about a quarter. The company reported its financial results recently; you can catch up on the latest numbers by reading our company report.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

While Shanghai Yanhua Smartech Group made a small profit, in the last year, we think that the market is probably more focussed on the top line growth at the moment. Generally speaking, we'd consider a stock like this alongside loss-making companies, simply because the quantum of the profit is so low. For shareholders to have confidence a company will grow profits significantly, it must grow revenue.

In the last 5 years Shanghai Yanhua Smartech Group saw its revenue shrink by 6.1% per year. Given that scenario, we wouldn't have expected the share price to rise 17% per year, but that's what it did. It just goes to show tht the market is forward looking, and it's not always easy to predict the future based on past trends. Still, we are a bit cautious in this kind of situation.

A Different Perspective

We're pleased to report that Shanghai Yanhua Smartech Group shareholders have received a total shareholder return of 54% over one year. That's better than the annualised return of 17% over half a decade, implying that the company is doing better recently. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
