杠杆投资者融资交易行为模式研究——来自A股市场的经验证据

自2010年证监会推出融资融券方案以来,A股市场上融资交易和融资余额都出现了较为显著的增长.目前A股市场上融资余额总量已达到万亿元的水平,对于中国股市的重要性日趋增加.有鉴于此,有必要对杠杆投资者的融资交易行为模式以及其对A股定价机制的影响进行更加深入地研究.本文通过实证研究检验杠杆投资者的融资交易行为模式与市场回报率、流动性等重要指标之间的相关关系.研究发现,滞后股票收益与杠杆投资者的净融资交易额之间存在着显著的正相关关系,说明我国杠杆投资者总体而言是追涨杀跌的趋势追逐者.股票价格下跌对融资交易的影响显著大于股票价格上涨所带来的影响,且这种不对称性在很大程度上是由市场收益而非个股异质性收益所引起的.此外,杠杆投资者的融资交易行为与未来股票周度收益之间存在负相关关系,这种负相关主要是由融资净卖出所引起的.

Intraday Price Change and Trading Volume Relations in the Stock and Stock Option Markets

This study investigates intraday relations between price changes and trading volume of options and stocks for a sample of firms whose options traded on the CBOE during the first quarter of 1986. After purging the price change series of the effects of bid/ask spreads, multivariate time-series analysis is used to estimate the lead/lag relation between the price changes in the option and stock markets. The results indicate that price changes in the stock market lead the option market by as much as fifteen minutes. The analysis of trading volume indicates that the stock market lead may be even longer.     

Reputation Effects in Trading on the New York Stock Exchange

Theory suggests that reputations allow nonanonymous markets to attenuate adverse selection in trading. We identify instances in which New York Stock Exchange (NYSE) stocks experience trading floor relocations. Although specialists follow the stocks to their new locations, most brokers do not. We find a discernable increase in liquidity costs around a stock's relocation that is larger for stocks with higher adverse selection and greater broker turnover. We also find that floor brokers relocating with the stock obtain lower trading costs than brokers not moving and brokers beginning trading post‐move. Our results suggest that reputation plays an important role in the NYSE's liquidity provision process.

Stock Price Behavior over Trading and Non-trading Periods: Evidence from the Taiwan Stock Exchange

This paper examines the stock price behavior in the trading and non-trading periods for stocks listed on the Taiwan Stock Exchange over 1971-96. The results indicate that the trading-time return variances are higher than the non-trading-time return variances especially for the larger trading-volume quintiles. This result is consistent with the private information hypothesis. Moreover, open-to-open return variances are higher than close-to-close return variances. Since both the opening and the closing transactions are conducted by the call auction procedure, the results are consistent with the trading halt hypothesis but not with the trading mechanism hypothesis.

The Time Variation of Risk and Return in the Foreign Exchange and Stock Markets

This paper attempts to determine whether the fluctuations of conditional first and second moments—which are observed for many assets—are consistent with the Sharpe-Lintner-Mossin capital asset pricing model. We test the mean-variance model under several different assumptions about the time variation of conditional second moments of returns, using weekly data from July 1974 to December 1986, that include returns on a portfolio composed of dollar, Deutsche mark, sterling, and Swiss franc assets, together with the U.S. stock market. The results indicate that estimated conditional variances cannot explain the observed time variation of risk premia.     

The Market Quality of Dealer versus Hybrid Markets: The Case of Moderately Liquid Securities

Abstract:  Over the last decade, electronic limit-order trading systems have been sweeping securities exchanges around the world. This paper studies a transitional case, namely, the commencement of trading of a group of moderately liquid stocks on SETS of the London Stock Exchange. The evidence reveals that the liquidity of those stocks dropped substantially after the introduction of the limit order book and the removal of the market makers' obligations. This transition provides an example that a hybrid market with a limit order book and voluntary dealers may not perform as well as a dealership market with obligatory market makers.     

Reactions of the London Stock Exchange to Company Trading Statement Announcements

Using event study methodology, we examine market reactions to nearly 2,000 trading statements during the period 1995‐2001. We find that profit warnings outnumber upgrades by 50%, and, in line with previous US studies, we find that market reaction to the actual announcements is considerably greater for profit warnings than for upgrades.Sub-samples demonstrate significant market reaction to profit warnings for all sizecontrolled portfolios, but that reaction to the announcements is greatest for small companies.Examination of pre- and post-announcement CARs shows no pre-announcement market anticipation of the announcements.Post-announcement there is a significant positive abnormal return on the day after the announcement of bad news for the small company subsample.Other post-announcement results are small and insignificant.Trading volume results are consistent with this picture. Finally, when the trading statements are examined for news on turnover and margin changes, we find that the market reaction to margin changes is greater than market reaction to turnover changes.     

The Effects of Trading Methods on Volatility and Liquidity: Evidence from the Taiwan Stock Exchange

This study contrasts the call and continuous auction methods using Taiwan Stock Exchange data. Volatility under the call market method is approximately one-half of that under the continuous auction method. The call market method is more effective in reducing the volatility of high-volume stocks than low-volume stocks. This contradicts conventional wisdom which suggests that the call market method is superior for thinly traded stocks, while the continuous auction method is preferred for heavily traded stocks. The call market method does not impair liquidity and price discovery. The call market appears more efficient than in the continuous auction market.     

Trading and Liquidity on the Tokyo Stock Exchange: A Bird's Eye View

The trading mechanism for equities on the Tokyo Stock Exchange (TSE) stands in sharp contrast to the primary mechanisms used to trade stocks in the United States. In the United States, exchange-designated specialists have affirmative obligations to provide continuous liquidity to the market. Specialists offer simultaneous and tight quotes to both buy and sell and supply sufficient liquidity to limit the magnitude of price changes between consecutive transactions. In contradistinction, the TSE has no exchange-designated liquidity suppliers. Instead, liquidity is provided through a public limit order book, and liquidity is organized through restrictions on maximum price changes between trades that serve to slow down trading. In this article, we examine the efficacy of the TSE's trading mechanisms at providing liquidity. Our analysis is based on a complete record of transactions and best-bid and best-offer quotes for most stocks in the First Section of the TSE over a period of 26 months. We study the size of the bid-ask spread and its cross-sectional and intertemporal stability; intertemporal patterns in returns, volatility, volume, trade size, and the frequency of trades; and market depth based on the response of quotes to trades and the frequency of trading halts and warning quotes.     

Securities trading in the absence of dealers: trades and quotes on the Tokyo Stock Exchange

This article investigates the behaviour of intraday trades andquotes for individual stocks on the Tokyo Stock Exchange (TSE).We examine the transaction and quote record for three firmsfor the first 3 months of 1990. Our findings suggest that theimmediacy available (at least for small trades) in the marketis high, despite the reliance on public limit orders to supplyliquidity. When orders that would otherwise walk through thelimit order book are converted into limit orders, executionis delayed, but some orders execute (at least in part) at morefavorable prices.     

Transaction Costs and Price Volatility: New Evidence from the Tokyo Stock Exchange

We investigate the volatility impacts of the full commission deregulation in Japan in October 1999, and find that the deregulation overall tends to significantly increase price volatility in the Japanese equity market, using alternative model specifications and control variables. This finding contrasts with previous evidence that implies a positive relation between transaction costs and price volatility, while consistent from the converse with the hypothesis proposed by Stiglitz (1989) and Summers and Summers (1989). Our results suggest that imposing higher transaction costs might still be a feasible policy tool for stabilizing the market by curbing short-term noise trading.
