This paper examines the impact of TSE Saturday trading on daily TOPIX returns and TSE trading volume over the January 1976
to January 1989 period. Saturday trading is shown to have no significant impact on mean stock returns for the other days of
the week. However, a significant shift in the pattern of Monday and Tuesday TOPIX returns is documented in the post-August
1986 period. This shift does not appear to be related to Saturday trading. TSE Saturday trading is found to have a significant
impact on the variance of stock returns on surrounding days. In addition, trading volume is significantly lower on trading
days surrounding Saturday trading. These findings are relevant to the timing of portfolio adjustment decisions. 相似文献

Noise trading and prime and score premiums 总被引:1,自引:0,他引:1
This paper documents that a common element drives the time-series variation of the premium pricing of Primes and Scores. I argue that this common element is noise trading. The noise trading model of Delong, Shleifer, Summers and Waldmann (1990) predicts that returns on assets that are predominantly traded by noise traders will be correlated, since the misperceptions of noise traders are cross-sectionally correlated. Consistent with the noise trading hypothesis, changes in the average premium of Primes and Scores, which are predominantly traded by individual investors, are correlated with both changes in average discounts of closed-end funds and small firms returns. These empirical facts provide additional evidence that noise traders can affect security prices. 相似文献

This paper studies the return reversals of exchange traded real estate securities using an arbitrage portfolio approach. Using the approach, we find that there exist significant return reversals in such securities. These return reversals could be exploited by arbitrage traders if trading costs can be ignored. However, the arbitrage profits disappear after deducting trading costs and taking into account the implicit cost of bid-ask spread. Thus, the real estate securities market is efficient at weekly intervals in the sense that one could not exploit the price reversals via some simple trading rules. 相似文献

Summary. This paper develops a model of speculative trading in a large economy with a continuum of investors. In our model the investors are assumed to have diverse beliefs which are rational in the sense of being compatible with observed data. We demonstrate the existence of price amplification effects and show that the equilibrium prices can be higher or lower than the rational expectation equilibrium price. It is also shown that trading volume is positively related to the directions of price changes. Moreover, we study how asset price volatility and trading volume are influenced by belief structures, short selling constraints and the amount of fund available for investment.Received: 23 January 2003, Revised: 30 April 2003, JEL Classification Numbers:

It has been alleged that firms and analysts engage in an "earnings‐guidance game" where analysts first issue optimistic earnings forecasts and then "walk down" their estimates to a level that firms can beat at the official earnings announcement. We examine whether the walk‐down to beatable targets is associated with managerial incentives to sell stock after earnings announcements on the firm's behalf (through new equity issuance) or from their personal accounts (through option exercises and stock sales). Consistent with these hypotheses, we find that the walk‐down to beatable targets is most pronounced when firms or insiders are net sellers of stock after an earnings announcement. These findings provide new insights on the impact of capital‐market incentives on communications between managers and analysts. 相似文献

This paper demonstrates that a post-announcement earnings drift, which is often advanced as an example of market irrationality, can arise even if traders act rationally on their information. Specifically, we show that in the presence of share supply variations which are unrelated to information, there is a positive correlation between the unexpected component of current public signals and future price changes. Such a correlation arises from the fact that while prices reveal private information that cannot be found in public signals, non-information based trading distorts the information content of prices relative to the implications of both private and public information. Under these circumstances, markets may appear semi-strong inefficient and slow to respond to earnings announcements even though information is processed in a timely and efficient manner. Our findings correspond well with previously documented empirical evidence and suggest that the robustness of earnings-based anomalies may be rational outcomes of varying uncertain share supply. 相似文献

This paper analyzes agreements between governments that determine the division of policy-making power between central and regional governments. Our analysis demonstrates that initial circumstances and political risks affect the degree of centralization that will be adopted, and that asymmetric forms of federalism are often consequences of ongoing negotiations between regional and central governments over the assignment of policy-making authority. We analyze three settings where gains from constitutional exchange may exist: (i) the under-centralized state, (ii) the over-centralized state, and (iii) the constitutional convention. In each case, an asymmetric form of federalism is the predicted outcome, although the degree of asymmetry differs according to starting point. Modern and historical examples are used to illustrate the relevance of our analysis. 相似文献

随着证券市场规模的扩大及机构投资者规模的壮大,机构投资者对市场流动性的需求日益剧增,大宗交易制度是满足投资者流动性需求的制度性创新。由于大宗交易的数量较大,其交易价格有别于正常交易规模的价格。本文利用沪深交易所的大宗交易数据实证探讨大宗交易价格及其影响因素。研究结果表明,大部分大宗交易价格低于当日收盘价格,呈现流动性折价现象,折价率达到1.27%:研究还发现,折价水平还受交易数量、正常交易时间段股票流动性水平、市场流动性水平及股价波幅等因素影响。 相似文献
