　　《证券日报》市场研究中心和WIND数据统计显示，截至4月21日，已有476家公司披露了一季报。汇总这些公司一季报中前十大流通股东的持股变动情况，以及基金一季报所公布的前十大重仓股的变动情况，从统计数据中发现，机构们在一季度集体加仓机械设备行业。

　　当然，不同机构重点选择的行业也不尽相同。一向标榜为价值投资者社保基金重点加仓机械设备行业；QFII却独爱电子元器件行业，将手中棋子重点布局于横店东磁、宇顺电子、南洋科技、兴森科技等电子元器件类股票。

　　令人关注的是，社保基金新进或继续增持的个股中，有20只重仓股今年中期业绩提前预告。其中，17只业绩预喜，而精华制药、荣盛石化、鸿路钢构、永太科技和广联达等5只社保新进或继续增持股今年中期业绩预增，均为中小板的品种。此外，对于一季度QFII新进或继续增持的重仓股中，有22只重仓股今年中期业绩提前预告（17只业绩预喜、5只业绩预忧），而探路者、英特集团、鱼跃医疗、新北洋和兴森科技等5只QFII新进或继续增持股今年中期业绩预增，为中小板和创业板的品种。对比发现，今年一季度社保基金和QFII加大对中小板和创业板的今年中期业绩预增股投资力度。

　　社保基金一季度建仓21股

　　统计显示，截至4月21日，社保基金建仓21只个股、继续加仓14只个股，对12只个股进行了减资，继续对15只个股进行“留守”。在社保一季度新建仓的21只个股中，新兴铸管（1000.00万股）、北大荒（694.00万股）、友好集团（520.21万股）、滨化股份（329.99万股）、巨力索具（300.00万股）、黄河旋风（299.99万股）、大有能源（200.00万股）、深天健（200.00万股）、金字火腿（148.00万股）、山东矿机（130.94万股）、泰尔重工（130.00万股）、鸿路钢构（129.98万股）和启明信息（120.00万股）等13只社保基金持股数量超100万股。

　　比较典型的是鸿路钢构，该股一季度本是钢结构产业的淡季，而业绩却倍增，公司实现营业收入6.95亿元，较去年同期增长104.67%；实现归属于上市公司股东的净利润2879.42万元，较去年同期增长155.31%。公司表示，营业总收入的大幅增加是因为钢结构市场需求旺盛，产销规模均出现大幅度增长，预计公司2011年中期净利润预增50%-80%。业绩稳定增长吸引机构投资者的眼球，一季度末全国社保基金109组合新进129.98万股，持股比例为4.78%；还有5只基金也是一季度新建仓，累计持股数为512.50万股。

　　今年一季度社保基金对14只个股实施加仓行动，这些个股分别为山煤国际（增持535.10万股）、康力电梯（增持533.04万股）、三友化工（增持422.92万股）、海南航空（增持400.20万股）、黑猫股份（增持400.00万股）、永太科技（增持170.10万股）、天山股份（增持160.01万股）、瑞凌股份（增持120.00万股）、友阿股份（增持87.90万股）、红日药业（增持51.74万股）、宇顺电子（增持50.88万股）、长春高新（增持32.99万股）、广联达（增持17.02万股）和劲胜股份（增持15.12万股）。

　　比较典型的是山煤国际，一季度末的前十大流通股东中有5家基金，2家保险，2家社保，共持有4889万股；其中3家易方达系基金持有1949万股，合计占流通盘比例为10.79%；两家中国人寿保险账户持有1159万股，一季度加仓211万股；社保一一零持有567万股未变，社保一零二持有535万股，为一季度新进。季报显示，一季度实现净利润2.17亿元，同比增长93%，每股收益0.29元。长江证券表示，山煤国际的1季度同比环比均大幅回升，2011年新建矿正式投产，预计2011年-2013年公司每股收益分别为1.605元、2.177元和2.322元，对应市盈率分别为20.31倍、14.98倍和14.04倍；考虑增发2.385亿股以及整合煤矿的盈利，维持“推荐”评级。

　　从行业角度来看，一季度社保基金新进或继续增持主要集中于机械设备、化工、医药生物、信息服务、电子元器件等五大行业，机械设备占7个席位、化工占5个席位、医药生物、信息服务、电子元器件等行业各占3个席位。其中，社保基金重仓持有的机械设备股分别为康力电梯（603.00万股）、巨力索具（300.00万股）、黄河旋风（299.99万股）、瑞凌股份（150.00万股）、山东矿机（130.94万股）、泰尔重工（130.00万股）和金杯电工（70.00万股）。

　　QFII一季度建仓25股

　　统计显示，截至4月21日，QFII建仓25只个股、继续加仓8只个股，对6只个股进行了减资，继续对6只个股进行“留守”。在QFII一季度新建仓的25只个股中，万科A（7544.21万股）、嘉凯城（1908.99万股）、华联综超（1023.73万股）、平高电气（972.90万股）、泸州老窖（843.98万股）、英特集团（409.92万股）、湖北宜化（394.72万股）、鱼跃医疗（390.21万股）、方正科技（377.61万股）、株冶集团（350.00万股）和横店东磁（220.00万股）等11只QFII持股数量超200万股。

　　比较典型的是鱼跃医疗，一季度末的十大流通股东中，汇添富旗下基金合计持有572.86万股（上期为585.23万股），新进三家QFII马丁可利投资、荷兰安智银行、东方汇理银行分别持有172.71万股、139.37万股、78.13万股。公司表示，随着募投项目的逐步投产，公司主要产品的产能大幅提高，公司产品产销两旺，经营业绩持续增长，预计2011年1-6月净利润同比增长50-80%。业绩逐渐上升，吸引众QFII机构投资者的提前入驻。

　　今年一季度QFII对8只个股实施加仓行动，这些个股分别为凌钢股份（增持753.98万股）、九阳股份（增持513.26万股）、东阿阿胶（增持187.85万股）、鲁阳股份（增持178.51万股）、*ST精伦（增持170.82万股）、探路者（增持119.36万股）、四维图新（增持77.74万股）和天威保变（增持10.00万股）。

　　比较典型的是*ST精伦，前十大流通股东中仅有的1家机构QFII-哥伦比亚大学持有886万股(增持171万股)。新进平安信托-从容优势一期和二

　　期合计持有327万股，而股东人数较上期减少8.55%，筹码集中。公司表示，一季度公司控制类产品、身份证阅读机具收入较上年同期上升，主营业务持续增长所致，净利润同比实现扭亏为盈，营业收入实现增长125.55%。

　　从行业角度来看，一季度QFII新进或继续增持主要集中于机械设备、电子元器件、化工、家用电器、信息设备等五大行业，机械设备占5席，这些个股分别为平高电气（972.90万股）、天威保变（260.04万股）、鑫龙电器（100.00万股）、晋亿实业（80.00万股）和胜利精密（14.47万股）。而电子元器件占4个席位，这些个股分别为横店东磁（220.00万股）、宇顺电子（29.00万股）、兴森科技（18.10万股）和南洋科技（10.00万股）；化工、家用电器、信息服务等3行业均各占3席。
