我国设立开放式基金对证券二级市场的影响分析

2001年是我国证券市场改革的关键一年，因为在加入WTO以后，国外资金将大量涌入我国的证券市场，这必将对我国幼稚的证券市场产生巨大的冲击。鉴于我国目前的投资近90％都是个人投资，证券市场监管部门在2002年就多次明确提出要积极培育机构投资，并将超常规培育机构投资列入议事日程，基金（开放式投资基金）是我国目前主要的机构投资。然而，开放式基金的面市必将对二级市场产生重大的影响，这种影响关键在于开放式基金参与各方行为的理性程度，即基金管理人专家理财的理性投资策略、市场上投资的投资与投机行为、监管部门的监管。     

战术跳频电台伪码序列的研究

<正> 今年以来,我国陆续推出新基金入市,此后又给予新基金配售新股等一系列优惠政策支持,显示了管理层大力发展我国基金业,培育理性机构投资者,以稳定我国证券市场的决心。近期推出的基金类型都是封闭式基金。在我国证券市场尚不完善、投机气氛较浓厚、投资者还不成熟的环境下,封闭式基金可以防止市场不理性行为对基金的冲击,有利于基金的稳定运作。但是,从长远来看,开放式基金代表我国基金业的发展方向。在当前我国证券市场具备一定基础的情况下,积极进行开放式基金的试点具有积极意义。

Leaders and followers: emerging market fund behavior during tranquil and turbulent times

Recent episodes of capital market volatility and contagion have brought up many questions about the behavior of international investors. We address some of these questions, exploring the behavior of different types of emerging market equity funds with monthly data on individual country holdings. Consistent with the notion that fund behavior can largely be traced to redemptions by individual investors, we find that open-end funds withdraw more from vulnerable countries around crises than their closed-end counterparts. We show that open-end funds’ flows Granger-cause closed-end funds investments, possibly because the closed-end funds are forced to follow their more fickle open-end counterparts. Single-country fund flows precede those of global funds, suggesting an informational advantage of the former. The evidence does not support the notion that small funds are at a disadvantage in gathering country information.     

我国券商与证券投资基金的惯性反转策略比较研究——基于交易策略弹性指数

为了克服经典GTW模型的缺陷,构造了衡量机构投资者惯性反转策略的指标——"交易策略弹性指数",并以此对中国市场上券商、开放式基金、封闭式基金的行为进行实证研究和比较分析。研究表明,基于股票的当期收益,券商在半数研究期内倾向于采取反转交易策略,而开放式基金和封闭式基金则倾向于采取惯性交易策略,券商可以在一定程度上"中和"开放式基金和封闭式基金行为对市场的影响。

Publicly traded venture capital funds: implications for institutional “fund of funds” investors

Institutional investors supply the bulk of the funds which are used by venture capital investment firms in financing emerging growth companies. These investors typically place their funds in a number of venture capital firms, thus achieving diversification across a range of investment philosophy, geography, management, industry, investment life cycle stage and type of security. Essentially, each institutional investor manages a “fund of funds,” attempting through the principles of portfolio theory to reduce the risk of participating in the venture capital business while retaining the up-side potential which was the original source of attraction to the business. Because most venture capital investment firms are privately held limited partnerships, it is very difficult to measure risk adjusted rates of return on these funds on a continuous basis.In this paper, we use the set of twelve publicly traded venture capital firms as a proxy to develop insight regarding the risk reduction effect of investment in a portfolio of venture capital funds, i.e., a fund of funds. Measurements of weekly total returns for the shares of these funds are compared with similar returns on a set of comparably sized “maximum capital gain” mutual funds and the daily return of the S&P 500 Index. A comparison of returns on an individual fund basis, as well as a correlation of daily returns of these individual funds, were made. In order to adjust for any systematic bias resulting from the “thin market” characteristic of the securities of the firms being observed, the Scholes-Williams beta estimation technique was used to reduce the effects of nonsynchronous trading.The results indicate that superior returns are realized on such portfolios when compared with portfolios of growth-oriented mutual funds and with the S&P 500 Index. This is the case whether the portfolios are equally weighted (i.e., “naive”) or constructed to be mean-variant efficient, ex ante, according to the capital asset pricing model. When compared individually, more of the venture funds dominated the S&P Market Index than did the mutual funds and by much larger margins. When combined in portfolios, the venture capital funds demonstrated very low beta coefficients and very low covariance of returns among portfolio components when compared with portfolios of mutual funds. To aid in interpreting these results, we analyzed the discounts and premia from net asset value on the funds involved and compared them to Thompson's findings regarding the contribution of such differences to abnormal returns. We found that observed excess returns greatly exceed the level which would be explained by these differences.The implications of these results for the practitioner are significant. They essentially tell us that, while investment in individual venture capital deals is considered to have high risk relative to potential return, combinations of deals (i.e., venture capital portfolios) were shown to produce superior risk adjusted returns in the market place. Further, these results show that further combining these portfolios into larger portfolios (i.e., “funds of funds”) provides even greater excess returns over the market index, thus plausibly explaining the “fund of funds” approach to venture capital investment taken by many institutional investors.While the funds studied are relatively small and are either small business investment companies or business development companies, they serve as a useful proxy for the organized venture capital industry, despite the fact that the bulk of the funds in the industry are institutionally funded, private, closely held limited partnerships which do not trade continuously in an open market. These results demonstrate to investors the magnitude of the differences in risk adjusted total return between publicly traded venture capital funds and growth oriented mutual funds on an individual fund basis. They also demonstrate to investors the power of the “fund of funds” approach to institutional involvement in the venture capital business. Because such an approach produces better risk adjusted investment results for the institutional investor, it seems to justify a greater flow of capital into the business from more risk averse institutional investment sources. This may mean greater access to institutional funds for those seeking to form new venture capital funds. For entrepreneurs seeking venture capital funds for their young companies, it may also mean a lower potential cost of capital for the financing of business venturing. From the viewpoint of public policy makers interested in facilitating the funding of business venturing, it may provide insight regarding regulatory issues surrounding taxation and the barriers and incentives which affect venture capital investment.
