The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. To wit, the Serba Dinamik Holdings Berhad (KLSE:SERBADK) share price has flown 218% in the last three years. That sort of return is as solid as granite. It’s also good to see the share price up 14% over the last quarter.
