噪声交易与市场质量

本文通过行业、规模、负债和成长能力的配对,建立起32家上证50成份股上市公司的控制样本,然后运用合理的计量方法,首次估计出符合我国股市微观结构的噪声交易高频时间序列,在此基础上深入分析噪声交易与信息不对称、流动性、波动性和有效性等市场质量指标之间的经验关系,发现:我国股市私人信息具有较高的相关性和持久性;噪声交易提高了交投活跃程度,同时却扩大了执行成本和价格波动幅度;噪声交易与信息不对称的关系不大;噪声交易使实际价差缩小,进而削弱了市场有效性。由此可见,噪声交易是一把"双刃剑",只有继续改革价格形成机制、增强价值投资力量、引导长期资金入市、完善信息披露制度并强化交易监控,才能进一步提高我国股市的质量。

我国开放式基金的证券选择和市场时机把握能力研究

运用参数检验方法对我国42只股票型开放式基金的证券选择和市场时机把握能力进行了分年度检验,结果发现,开放式基金在2003年具有较强的证券选择能力,但不具备市场时机把握能力,在2004年上半年显示出了一定的市场时机把握能力,却从总体上表现出负向证券选择能力.基于2003年的基金年报分析显示,开放式基金在对未来市场趋势的预测上存在明显的"羊群行为".     

Liquidity, Transaction Costs, and Reintermediation in Electronic Markets

Relationships between trading cost, technology, and the nature of intermediation in the trading services industry are discussed. Electronic markets are linked to reductions in trading costs. Lower explicit costs are related to system development and operating costs. Electronic order book information is identified as a means of realizing implicit cost savings. The concept of liquidity management in electronic environments is introduced, and its potential is empirically illustrated. The empirical results suggest new roles for brokerage and exchange operations, and competition between the two. Competitive advantage with respect to the provision of liquidity management services is compared across types of intermediaries.

Traders’ choice between limit and market orders: evidence from NYSE stocks

In this paper, we examine a trader's order choice between market and limit orders using a sample of orders submitted through NYSE SuperDot. We find that traders place more limit orders relative to market orders when: (1) the spread is large, (2) the order size is large, and (3) they expect high transitory price volatility. A rise in informational volatility appears neither to increase nor decrease the placement of limit orders. We also find that a rise in lagged price volatility decreases the size of spread, which is driven by the increase in the placement of limit orders.     

Risk Aversion,Uncertain Information,and Market Efficiency

Abstract. We reexamine and extend tests of the uncertain information hypothesis (UIH) proposed by Brown, Harlow, and Tinic (1988, 1993). We find that their empirical results are sensitive to the sampling procedure employed and that their particular methodology does not sufficiently distinguish between event and nonevent periods. When the sampling procedure is modified to identify only relatively large, isolated events, the test results generally do not support the UIH. Instead, significant price shocks are consistently followed by short-lived price reversals. We observe this behavior following positive and negative events regardless of whether the event is classified as risk increasing or risk decreasing.     

Dynamic analysis of stock return volatility in an integrated international capital market

This paper examines the dynamic behavior of the stock return volatility for Canada, Japan, Germany, and the United Kingdom. The evidence indicates that international stock return volatility is mainly influenced by the U.S. stock return volatility and the exchange rate volatility, supporting the international capital market integration hypothesis. There seems to be some correlation between stock return volatility and macroeconomic volatility, but the effect is relatively weaker. In addition to the economic fundamentals, the noise component is found to be time varying, confirming the AR(MA)CH specifications in the stock return models.
