据统计,2002年度深沪A股市场已公布年报的1181家上市公司加权平均每股收益为0.16元,加权净资产收益率平均为6.20％。5家水务主业上市公司每股收益平均值达0.28元,是市场平均水平的1.8倍左右;主营利润率和业务利润率更是远远高于市场平均值,分别达到了57.92％、41.44％,净资产收益率也高于大盘4个多百分点。可以说,水务上市公司整体盈利能力相对比较突出。由图2可见,今年1～4月水务板块和大盘的走势基本趋同,5—8月水务板块未能跑赢大盘,收益率低于大盘4.0％。由于水务板块具有波动性较小、抗风险能力较强的特点。因此水务板块中的绩优公司适合作为投资组合中的防守型品种。

The profit margin and business profit margin of the main businesses are far above the market average, reaching 57.92% and 41.44 respectively %, Return on net assets also higher than the market more than 4 percentage points. It can be said that the overall profitability of listed water companies is relatively prominent. As can be seen from Figure 2, from January to April this year, the water sector and the broader market basically converged. From May to August, the water sector failed to outperform the broader market and the yield was 4.0% below the broader market. As the water sector with less volatility, strong anti-risk ability. Therefore, the Merit company in the water sector is suitable as a defensive breed in the portfolio.
