Using a novel data set covering all individual investors' stock market transactions in Norway over 10 years, we analyze whether individual investors have a preference for professionally close stocks, and whether they make excess returns on such investments. After excluding own‐company stock holdings, investors hold 11% of their portfolio in stocks within their two‐digit industry of employment. Given the poor hedging properties of such investments, one would expect abnormally high returns. In contrast, all estimates of abnormal returns are negative, in many cases statistically significant. Overconfidence seems the most likely explanation for the excessive trading in professionally close stocks. 相似文献

The relation between the square of the quoted bid-ask spread and two serial covariances—the serial covariance of transaction returns and the serial covariance of quoted returns—is modeled as a function of the probability of a price reversal, π, and the magnitude of a price change, ?, where ? is stated as a fraction of the quoted spread. Different models of the spread are contrasted in terms of the parameters, π and ?. Using data on the transaction prices and price quotations for NASDAQ/NMS stocks, π and ? are estimated and the relative importance of the components of the quoted spread—adverse information costs, order processing costs, and inventory holding costs—is determined. 相似文献

Building on contract theory, we argue that financial covenants control the conflicts of interest between lenders and borrowers via two different mechanisms. Capital covenants control agency problems by aligning debt holder–shareholder interests. Performance covenants serve as trip wires that limit agency problems via the transfer of control to lenders in states where the value of their claim is at risk. Companies trade off these mechanisms. Capital covenants impose costly restrictions on the capital structure, while performance covenants require contractible accounting information to be available. Consistent with these arguments, we find that the use of performance covenants relative to capital covenants is positively associated with (1) the financial constraints of the borrower, (2) the extent to which accounting information portrays credit risk, (3) the likelihood of contract renegotiation, and (4) the presence of contractual restrictions on managerial actions. Our findings suggest that accounting‐based covenants can improve contracting efficiency in two different ways. 相似文献

How Does Household Portfolio Diversification Vary with Financial Literacy and Financial Advice? 下载免费PDF全文
HANS‐MARTIN VON GAUDECKER 《The Journal of Finance》2015,70(2):489-507
Household investment mistakes are an important concern for researchers and policymakers alike. Portfolio underdiversification ranks among those mistakes that are potentially most costly. However, its roots and empirical importance are poorly understood. I estimate quantitatively meaningful diversification statistics and investigate their relationship with key variables. Nearly all households that score high on financial literacy or rely on professionals or private contacts for advice achieve reasonable investment outcomes. Compared to these groups, households with below‐median financial literacy that trust their own decision‐making capabilities lose an expected 50 bps on average. All group differences stem from the top of the loss distribution. 相似文献

We study short‐maturity (“weekly”) S&P 500 index options, which provide a direct way to analyze volatility and jump risks. Unlike longer‐dated options, they are largely insensitive to the risk of intertemporal shifts in the economic environment. Adopting a novel seminonparametric approach, we uncover variation in the negative jump tail risk, which is not spanned by market volatility and helps predict future equity returns. As such, our approach allows for easy identification of periods of heightened concerns about negative tail events that are not always “signaled” by the level of market volatility and elude standard asset pricing models. 相似文献

We examine whether earnings reconciliation from U.K. generally accepted accounting principles (GAAP) to International Financial Reporting Standards (IFRS) convey information. As a result of debt contracting, mandatory accounting changes are expected to affect the likelihood of violating existing covenants based on rolling GAAP, leading to a redistribution of wealth between shareholders and lenders. Consistent with this prediction, we find significant market reactions to IFRS reconciliation announcements. These market reactions are more pronounced among firms that face a greater likelihood and costs of covenant violation and early announcements. While the association between later announcements and weaker market reactions is consistent with contractual implications of technical changes to earnings, which investors quickly learn to predict, it is inconsistent with IFRS forcing all firms in the sample to reveal firm-specific information through accruals. Thus, by showing that mandatory IFRS also affects debt contracting, we expand on existing IFRS research that focuses on how accounting quality and cost of capital are impacted. 相似文献

We propose using model‐free yield quadratic variation measures computed from intraday data as a tool for specification testing and selection of dynamic term structure models. We find that the yield curve fails to span realized yield volatility in the U.S. Treasury market, as the systematic volatility factors are largely unrelated to the cross‐section of yields. We conclude that a broad class of affine diffusive, quadratic Gaussian, and affine jump‐diffusive models cannot accommodate the observed yield volatility dynamics. Hence, the Treasury market per se is incomplete, as yield volatility risk cannot be hedged solely through Treasury securities. 相似文献
