深市小微市值账户近五年盈亏情况报告

Profit and Loss Report of Small and Tiny Market Value Accounts of Shenzhen Market in the Past Five Years

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。

By analyzing the registry and settlement data from 1st Jan 2007 to 31th Dec 2011, the following conclusions can be drawn： in the past five years, the investors of the Shenzhen market have made profit of 62.2 billion and only acquired by institutional accounts. As to the proportion of the profit accounts, institutional accounts are the highest, and the tiny market value accounts are the highest among the individual accounts. The individual accounts, especially the small and tiny market value accounts, hold more ST stocks than institutional accounts, but they hold much less Shenzhen Compositional Index stocks than other accounts. They also have a lower trading frequency and a higher holding concentration. The earlier small and tiny market value accounts opened account, the more experience they have and the older they are, they are more likely to make profit; otherwise, the more frequently they trade, the more diverse of their holdings, they are more likely to make loss. Other types of accounts are similar to the small and tiny market value accounts.
