　　浙商证券策略分析师王伟俊向《大众证券报》表示：“公司的股东户数减少，可以表明很多中小投资者不看好选择离场，这也表明一只股票的筹码趋于集中，假设基金、保险、QFII等机构却在增加买入，这只能说明筹码正在向机构手中流去，这种股票的组合可以获得一定的超额收益。”

近七成股票现散户离场 Nearly seventy percent of the stock is now retail pitch

　　《大众证券报》观察到，就在上述40股票中，有28只股票在机构持股比例上具有对比意义，其中19只股票被机构加仓，也就说将近七成的个股出现了散户离场，机构趁机买入的现象。据Wind统计显示，基金、社保、QFII、保险、券商、企业年金这五大机构在二季度末持仓幅度比较高的是海大集团(002311,股吧)、海思科、峨眉山A、辉煌科技、华策影视、首航节能、双鹭药业、歌尔声学。

　　前期大涨的海思科几乎被泰达宏利基金管理有限公司旗下的4只基金产品抱团持有，且都为首次买入，约占海思科流通总股本的18%。海思科从3月底左右的17元左右一直上涨到7月中旬的32元附近，最大涨幅几乎翻番。值得注意的是，全国社保基金102组合在今年二季度继续加仓海大集团，持有997万股，总市值约为1.7亿，而海大集团的股东户数却是从9267户减少至8673户。海大集团全年涨幅37%，二季度以来涨幅超过20%，远远跑赢大盘同期涨幅。

　　对此，浙江某私募人士也向记者分析：“散户割肉离场时，反倒是机构趁机买入廉价筹码的时候，也是多数股票上涨的起始，A股史上无数次上演这一幕幕，中报披露期间正是挖掘这类品种的时候。筹码集中度提升、业绩预增不错或有良好基本面支撑的个股在大盘反弹时，上涨空间具有更大优势，部分滞涨股值得关注。” 记者 徐海峰
