摘要
本文以19支开放式基金和23支封闭式基金为研究样本,通过改进PCM模型,设计适用于非有效市场或弱有效市场的指标S,来考察我国证券投资基金在2005年1月1日至2007年6月30日这段研究区间内的积极资产组合管理能力,并对开放式基金和封闭式基金的积极资产组合管理能力进行比较分析。研究发现,开放式基金和封闭式基金均有较强的积极资产组合管理能力;封闭式基金的积极资产组合管理能力整体要高于开放式基金,特别是在上涨和震荡行情中;同时,市场走势的波动也会对基金的积极资产组合管理能力产生一定的影响。

Study found that both the open-end funds and the closed-end funds have high active portfolio capabilities, but the closed-end funds appeared to have higher active portfolio capabilities than open-and funds, especially in higher prices and shocks. In the same time, market fluctuations will have a certain impact on the fund' s active portfolio management capabilities, but not absolute.
