本周是“五一”长假后的第一个交易周,也是证监会启动股权分置改革试点的第一周。试点的实施不仅没有拉动市场出现上涨,反而使其在对诸多不确定性的忧虑中大幅下跌。前期表现良好的蓝筹股大幅下挫是本周市场最不同于以往的特征。5月9日至5月13日,上证综合指数下跌51.52点至1107 This week is the first trading week after the May Day holiday and the first week of the CSRC pilot reform of share-holding structure. The implementation of the pilot not only failed to boost the market, but caused it to plummet in a great deal of uncertainty. The sharp drop in good blue chips during the previous period was the most unusual feature of the market this week. May 9 to May 13, the Shanghai Composite Index fell 51.52 points to 1107
