While stock picking isn't easy, for those willing to persist and learn, it is possible to buy shares in great companies, and generate wonderful returns. When you buy and hold the right company, the returns can make a huge difference to both you and your family. For example, Summi (Group) Holdings Limited (HKG:756) has generated a beautiful 317% return in just a single year. It's up an even more impressive 324% over the last quarter. And shareholders have also done well over the long term, with an increase of 148% in the last three years.

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder returns.

Summi (Group) Holdings isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. Shareholders of unprofitable companies usually expect strong revenue growth. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

In the last year Summi (Group) Holdings saw its revenue shrink by 29%. So it's very confusing to see that the share price gained a whopping 317%. It's pretty clear the market isn't basing its valuation on fundamental metrics like revenue. To us, a gain like this looks like speculation, but there might be historical trends to back it up.
