深市小微市值账户近五年盈亏情况报告

对2007年1月1日至2011年12月31日五年的登记结算数据进行分析显示:五年间深市证券账户盈利621.95亿元,所有账户中仅机构账户总体盈利。从盈亏账户比重来看,机构账户盈利占比最高,个人账户中,微型市值账户盈利占比最高。个人账户尤其是小微市值账户ST股持股比重高于机构账户,而深成指持股占比远低于中大市值账户和机构账户。并且,小微市值账户的交易频率远低于中大市值账户,而持股集中度高于中大市值账户与机构账户。小微市值账户的开户时间越早、投资经验越丰富、年龄越大,其盈利能力相对越强;反之,交易越频繁、投资越分散,盈利能力则随之降低。其他类型账户与小微市值账户的情况大致相同。
