The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But in contrast you can make much more than 100% if the company does well. To wit, the CIG ShangHai Co., Ltd. (SHSE:603083) share price has flown 288% in the last three years. Most would be happy with that. It's also up 27% in about a month.
Since it's been a strong week for CIG ShangHai shareholders, let's have a look at trend of the longer term fundamentals.
While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.
CIG ShangHai became profitable within the last three years. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

A Different Perspective
It's nice to see that CIG ShangHai shareholders have received a total shareholder return of 96% over the last 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. It's always interesting to track share price performance over the longer term. But to understand CIG ShangHai better, we need to consider many other factors. Case in point: We've spotted 2 warning signs for CIG ShangHai you should be aware of, and 1 of them makes us a bit uncomfortable.
