The simplest way to invest in stocks is to buy exchange traded funds. But you can significantly boost your returns by picking above-average stocks. For example, the China Isotope & Radiation Corporation (HKG:1763) share price is up 40% in the last year, clearly besting the market return of around 5.3% (not including dividends). If it can keep that out-performance up over the long term, investors will do very well! Note that businesses generally develop over the long term, so the returns over the last year might not reflect a long term trend.
