　　在主營及凈利潤穩(wěn)健增長的公司中，我們選擇(主營及凈利潤三年復(fù)合增長率≥50%)、(30%≤主營及凈利潤三年復(fù)合增長率≤50%)、(15%≤主營及凈利潤三年復(fù)合增長率≤30%)、(0%≤主營及凈利潤三年復(fù)合增長率≤15%)的四個組合條件作為對比研究，通過05年10月10日選擇的股票組合在不同時段后(3個月后、6個月后、9個月后、一年后);以及不同階段(下跌、筑底、拉升、盤整)的實證檢驗，我們發(fā)現(xiàn)主營及凈利潤三年復(fù)合增長率≥15%的股票組合整體上好于大盤平均水平，該組合具有在熊市中跌得晚、在牛市補漲階段更勝一籌的特性;在周期策略上，短線效果不明顯，持有周期6至9個月左右為最佳持有周期。

In the 23 newly selected stocks with a quarterly growth rate of three and a net profit of more than 50%, there were only 3 companies entering and leaving one company, such as CITIC Securities, whose performance rose sharply.

The main business and net profit increased by three years. Promote The main contribution comes from the improvement of the capital market in the past 06 years. The growth of such companies is not sound enough. However, as many as 20 companies continue to grow, this shows that the steady growth of enterprises still has a steady growth trend, such high-speed and robust growth enterprises are more favored by the market. For example, in October 10th 05, the steady growth stocks of the main business and net profit of three years of compound growth rate of 50% or more were four times in a year, the average was stronger than the market 100%, the highest 145%, and the lowest reached 78%.

It is noteworthy that, since the main and net profit of the three year composite stable growth index is based on the growth of the main and net profit in the past three years as the object of study, without considering the expected growth of the company's future main revenue and net profit, these enterprises have probably reached or near the peak after the rapid growth in the past three years, so they still need to grow up to the industry or enterprise. cycle Further research is needed to further explore the stocks that are still growing at high speed.
