Effective Market Study And Investment Strategy On New Energy Plate Market

The country’s economy is developing, and we had saw an appearance that financial markets already have a big effect on every corner of the economic and the social. Whether the market is effective or not is the problem that lots of scholars are studying. An efficient market can behaviors everyone in the market, effecting the economic and the social. So it is always called "rain chart". If the marker is healthy, the county must do many things for it. So we can use some different data to analyze different markets, and to view if it is an effective market, that is very important.In this paper, we elect the sector index data that it belongs to new energy plate to produce the analysis, the time of data is beginning at January 4,2013 and ending at November 3,2014.And in the article we also describe the theory of efficient market, model and test method. First of all, we use ADF test to determine the Log return sequence and the Price of log sequence in the empirical study stage, if they are stable. Under the condition of the Log return sequence is steady and Price of logarithmic sequence is not stable, we will use three kinds of statistical method to prove if there has correlation. The market is testified that it is non-effective by both Serial auto-correlative test and Variance ratio test, but the Run test receives different conclusion. To sum up, we think the market is waving between non-effective and effective.In the second part, we will select twenty-two public companies belong to the wind energy sector, doing factor analysis and cluster analysis, extracting the public factor. Making clear that the significance of the index in the whole course, we make an assay of the data, and doing the cluster analysis. In the end, the companies are break up into two classification, and we not only explain the ratio of the data, but also draw comparison chart about two class. The results indicate that the first class companies’ size is a little big, operation of funds is better. But what is more unfortunately is its profitability worse than the second category, the rate of business revenue increment is almost negative. The first class company is felt growing firm, so we recommend it is worth investing.
