【摘要】 本文通过选取2001年高低市盈率组合的各20家股票,计算其2001～2005年的投资回报事并进行假设检验和相关分析。本研究发现,我国股票市场投资,无论是采用高市盈率投资组合还是低市盈率投资组合,其投资回报率基本趋同,没有明显差异。投资回报主要是和股票指数相关,而与选择高市盈率组合还是低市盈率组合基本无关。从短期来看,低市盈率股票投资回报波动更大,更具有不确定性,也更具有风险性。更多还原

【Abstract】 Through choosing each 20 stocks in two groups which is high p/e ratio and low p/e ratio,this text computed rate of return on investment between 2001 and 2005,and did hypothesis testing and correlated analysis.Find that its rate of return on investment is no obvious difference on the stock market of our country,no matter adopt high p/e ratio investment combination or low p/e ratio investment combination. Investment repayment is mainly correlated with stock index,and basically no related with choosing the high pie ratio or the low p/e ratio. Viewed from a short time,low p/e ratio stock investment repayment fluctuates larger,have uncertainty even more,have risk even more too.更多还原
