Online Search Frequency,Retail Investor Overreaction,and the Cross-Section of Stock Returns: Evidence from the Chinese Stock Market

I find a strong negative relation between online search frequency and future returns on the Chinese stock market. I suggest that this effect captures retail investor overreaction to unexpected signals, because online search frequency reflects the efforts made by investors to obtain firm-specific knowledge. The effect is particularly strong in stocks with high information uncertainty (high analyst dispersion, big past earnings surprises, low analyst coverage, and large trading volume), whose intrinsic values are difficult or costly for investors to estimate. Online search frequency as a direct indicator of retail investors’ reaction to signals also sheds light on the idiosyncratic volatility (IVOL) puzzle. I find that this puzzle is more pronounced in high-search-frequency subsamples and disappears in low-search-frequency subsamples. Further evidence shows that high search frequency strengthens the negative IVOL effect in stocks with positive signals but weakens this effect in stocks with negative signals. I suggest that the IVOL puzzle in the Chinese market can be partially explained as a reversal following overreaction to positive signals by retail investors.     

External Conditions,the Evolution of Financial Risks,and the Informational Content of Stock Prices: The Case of Chile

ABSTRACT

In this article, we find that the dynamics of local financial risks in the Chilean stock market are associated with the evolution of external economic conditions, with a strong reduction in both idiosyncratic and systematic risks during periods of stable conditions. Despite this, we fail to find any significant change in the traditional measures of stock price synchronicity developed in the R² literature in our sample. We argue that these measures neglect the relationship between stock prices and fundamentals and find that the strength of the association between prices and fundamentals changes during our sample period, being much stronger during times of stable external conditions and diminished stock price volatility.

Investor structure and the informational efficiency of commodity futures prices

This article investigates the impact of the trading positions of hedgers (i.e., producers, merchants, processors, or users of a commodity), speculators (i.e., commodity pool operators, trading advisors, or hedge funds), and swap dealers on the price formation process in the agricultural, metal, and energy futures markets. The hedgers' relative positions exert negative impacts on price efficiency in commodity futures markets. Hedgers are less likely to be information motivated, so their trading delays the price formation process. However, speculators' positions have positive impacts on price efficiency because speculators correct pricing errors. This study also offers evidence that the role of swap dealers, similar to speculators in futures markets, is to provide liquidity and cross-market arbitrage. These findings highlight the role of producers, hedge funds, and swap dealers in price formation processes in commodity futures—information that is beneficial to academics, practitioners, and regulators.

Investor sentiment‐styled index in index futures market

In this paper, we define and analyze the sentiment‐styled index for the CSI 300 index futures in the Chinese futures market. Our sentiment‐styled index for the CSI 300 index futures from April 16, 2010 to April 30, 2019 is constructed by the first and second principal component analyses, rather than only by the first principal component analysis used in the Baker and Wurgler (Journal of Finance 61(4): 1645–1680, 2006) method. The sentiment‐styled index explains 78.38% of the sample variance. The vector error correction model is adapted to study the dynamics of cointegration of the sentiment‐styled index and the logarithmic futures price. We use the GARCH‐DCC model to illustrate the spillover effect between the sentiment‐styled index and the Chinese futures market. We show that this investor sentiment‐styled index does have the price discovery from the Granger causality and common factor weights and the hedging function from the Baba–Engle–Kraft–Kroner model empirically; furthermore, we use the curvature term of the sentiment‐styled index to determine the multiple unit roots. More empirical results for the sentiment‐styled index of the Chinese stock market, the sentiment‐styled index of the CSI 300 index futures, and the return of the CSI 300 index futures market are studied in this paper.     

国际投资者对中国股票资产的价值偏好：来自A-H股和A-B股折扣率的证据

国际投资者因中国经济快速成长而投资A股、H股、B股等中国股票资产。已有研究从硬分割和软分割角度研究了A-H和A-B股折扣率形成原因。本文进一步从国际与国内投资者的价值偏好差异来研究折扣率差异。对1999-2007年的面板数据采用固定效应估计方法,发现在控制其他因素后,折扣率和上市公司的价值变量显著负相关,表明国际投资者偏好价值型的中国股票资产,导致其折扣率偏低。相对信息不对称,价值偏好差异是更重要的资本市场软分割因素。

Environmental Conditions,Reservation Prices,and Time on the Market for Housing

A general analytical model to describe the impact of environmental disamenities on duration of sales is derived. A statistical technique to recover a sellers reservation price is proposed. An econometric procedure that consistently estimates market duration and a sellers reservation price is described. An application to the impact of highway noise on property values and market duration is presented. The estimation results show that, while highway noise has a significant negative impact on forming reservation prices and predicting sale prices, the noise effect on duration of sales is not statistically significant. Empirical evidence also shows a negative impact of market duration on reservation prices, which indicates an updating process for reservation prices over time.     

Do Assumptions About Factor Structure Matter in Empirical Tests of the APT?

The effect of assumptions about factor structure on empirical tests of multifactor models such as the Arbitrage Pricing Policy Theory has received little attention in the literature. Using data on securities traded on the London Stock Exchange, we examine whether returns are best described by an approximate factor structure and whether assumptions about correlations across idiosyncratic returns have a significant impact on estimated prices of risk and their significance. Our findings suggest that returns are best described by an approximate factor structure and, if this is taken into account when empirically testing the APT, six factors carry significant prices of risk. However, if a strict factor structure is imposed, no factors carry significant prices of risk. These findings suggest that assumptions about factor structure matter in empirically testing the APT.     

Investor attention,firm-specific characteristic,and momentum: A case of the Korean stock market

This study examines the sources of negative momentum profits by combining investor attention and the properties of common and firm-specific factors. We choose the Korean stock market as a good case to characterize the negative momentum profits identified in Asia. In both portfolio and stock analyses, a method is devised to generate return data involving the property of each common and firm-specific factor within stock groups by investor attention. This study found significant negative momentum profits within the stock group with high investor attention. This momentum effect is highly dependent on the reversed performance of the past loser portfolio, not the continued performance of the past winner portfolio, and this reversal is strongly attributable to the properties of firm-specific factors, and not those of common factors. These results are robustly consistent regardless of changes in empirical design and the consideration of influence factors, market dynamics, and other stock markets.     

Reexamining the managerial ownership effect on firm value

Whether equity-based compensation and equity ownership align the interests of managers with stockholders is an important question in finance. Early studies found an inverted U-shaped relation between managerial ownership and firm value, but later studies using firm fixed effects found no relation. Managerial ownership levels change very slowly over time which may mask an ownership effect on firm value when using a fixed effect model. This is due to a much smaller within firm variation than between firm variation. We demonstrate that using pay-performance semi-elasticity, rather than pay-performance sensitivity as a measure of managerial ownership incentives, results in meaningful variation within firm over time. The greater within firm variation increases the power to detect a relation between managerial ownership and firm value with fixed effect regressions. As in the early research on this issue, we find a significant inverted U-shaped relation between managerial ownership and Tobin's Q in fixed effects regressions and after controlling for endogeneity with both two-stage and three-stage least squares regressions. Our results are consistent with incentive alignment at low levels and risk aversion at high levels of managerial ownership.
