While shareholders of Zhejiang Yonggui Electric Equipment (SZSE:300351) are in the black over 5 years, those who bought a week ago aren't so fortunate

The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on a lighter note, a good company can see its share price rise well over 100%. For example, the Zhejiang Yonggui Electric Equipment Co., Ltd. (SZSE:300351) share price has soared 101% in the last half decade. Most would be very happy with that. It's also good to see the share price up 29% over the last quarter. But this move may well have been assisted by the reasonably buoyant market (up 33% in 90 days).

While the stock has fallen 5.5% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.
