Research On Key Techniques Of Radio Resource Allocation In Relay-Enhanced Cellular Networks

After more than 30 years of vigorous growth,China's capital market has made remarkable achievements.We usually use two methods for analysis: fundamental analysis based on financial indicators and valuation indicators,and technical analysis based on K line and volume.Most people study the two completely separately and verify them from a single point of view.But fundamental analysis and technical analysis is not a simple analysis.In the process of stock investment,it is necessary to combine financial,valuation and technical indicators.Fundamentals are the analysis of the target company's profitability,product,management,market valuation and other financial data,and are the basis of investment behavior.Technical analysis is to study the market's response to it,is an important indicator of investment opportunities.Based on the above realistic background and theoretical background,this paper,on the basis of previous studies,constructed an investment strategy combining fundamental index analysis or technical index analysis.Unlike an investment strategy that uses only fundamental analysis or technical indicators analysis,this paper combines fundamental analysis with technical indicators based on financial indicators.From the financial indicators(ROE,growth rate of EPS),valuation index(PE,PCF,CAP),technical indicators(Moving averages)three dimensions of sample stock screening,each index screening inspection after the completion of the screening index is arranged on the top 60% of the stock on to the next target group,each index in years,divided into 5 groups description analysis.Explore whether the investment strategy of the three-dimension stock selection method can be more optimized.The evaluation criteria in this paper will start from the two aspects of return and risk,not only to test the return,to verify whether you can get excess return in China's a-share market,whether you can beat the CSI 300 index during the sample period of the stable return of A value.In addition,Sharpe ratio,R square are also included in the test,and risk factors are also included in the test.Through the calculation and statistics of financial indicators and valuation indicators,not only is the arithmetic average value and final cumulative value of the yield better than the benchmark portfolio,but the risk indicators show that the downside risk is small and the number of futures with positive yield is more,indicating that the fundamentals of the securities market can be seriously studied to obtain excess returns.Although the investment strategy with technical indicators did not achieve greater returns than the fundamental value portfolio during the investment period,the effect of avoiding stock market pullback and asset shrinkage was obvious.
