    点评：昨日，受到获利盘套现影响，股指放量下挫44.8点，并重新回到半年线的下方，两市B股也出现大幅下挫，其中沪市B股呈现普跌之势，仅三毛B股一只小幅上涨。应该说，从近期的市场走势以及股权分置改革的背景分析，与A市场相比，B股昨日的大幅回调更显得理所当然。首先，B股在经过7月15日和18日两个交易日的大跌后，于7月22日集体反弹，至本周三多数个股处于上升通道之中，并且没有像样的回调，相当一部分个股累计涨幅超过30%，获利盘套现欲望较为强烈；其次，在股改的背景下，日前有消息称流通B股不获得对价，而相应A股对价空间增大，在比价效应下，B股下跌风险较高，从统计中我们也可以发现，昨日跌幅较大的B股多数同时含有A股，而昨日逆势上涨的14只B股中仅有6只包含A股。
