This paper applies the Least Absolute Shrinkage and Selection Operator (LASSO) to make rolling one‐minute‐ahead return forecasts using the entire cross‐section of lagged returns as candidate predictors. The LASSO increases both out‐of‐sample fit and forecast‐implied Sharpe ratios. This out‐of‐sample success comes from identifying predictors that are unexpected, short‐lived, and sparse. Although the LASSO uses a statistical rule rather than economic intuition to identify predictors, the predictors it identifies are nevertheless associated with economically meaningful events: the LASSO tends to identify as predictors stocks with news about fundamentals.  相似文献

This paper examines the role of nonfundamentals‐based sentiment in house price dynamics, including the well‐documented volatility and persistence of house prices during booms and busts. To measure and isolate sentiment's effect, we employ survey‐based indicators that proxy for the sentiment of three major agents in housing markets: home buyers (demand side), home builders (supply side), and lenders (credit suppliers). After orthogonalizing each sentiment measure against a broad set of fundamental variables, we find strong and consistent evidence that the changing sentiment of all three sets of market participants predicts house price appreciation in subsequent quarters, above and beyond the impact of changes in lagged price changes, fundamentals, and market liquidity. More specifically, a one‐standard‐deviation shock to market sentiment is associated with a 32–57 basis point increase in real house price appreciation over the next two quarters. These price effects are large relative to the average real price appreciation of 71 basis points per quarter observed over the full sample period. Moreover, housing market sentiment and its effect on real house prices is highly persistent. The results also reveal that the dynamic relation between sentiment and house prices can create feedback effects that contribute to the persistence typically observed in house price movements during boom and bust cycles.  相似文献

We ask whether credit rating agencies receive higher fees and gain greater market share when they provide more favorable ratings. To investigate this question, we use the 2010 rating scale recalibration by Moody's and Fitch, which increased ratings absent any underlying change in issuer credit quality. Consistent with prior research, we find that the recalibration allowed the clients of Moody's and Fitch to receive better ratings and lower yields. We add to this evidence by showing that the recalibration also led to larger fees and to increases in the market shares of Moody's and Fitch. These results are consistent with critics’ concerns about the effects of the issuer‐pay model on the credit ratings market.  相似文献

Catholic views on personhood and human nature include emphasis on the dignity of each person, from womb to tomb. The claims made for this inviolable dignity invariably stem from the recognition that all human beings, regardless of their state of dependency, are made in the image of God and are thus the bearers of certain moral rights. But in our fallen state that image is wounded and needs to be repaired. Hence, Christians need to learn to recapitulate the life of Christ in their own lives by growing through the stages of human life according to the model that He presents to us. There are not only individual but corporate aspects to this growth. Catholic Social Teaching offers insights on the corporate and social condition in which we find ourselves. It has a healthy respect for the economic laws of the market and for the technical intricacies of efficient decision‐making processes in local, national, and world economies, but out of respect for human nature there are moral norms that need to be respected and that may never be violated. On the topic of property and private ownership, considerable attention is given to the very purpose of private property (namely, to provide individuals with a kind of independence that enhances their ability to do their duties to their dependence and that extends their freedom). But always correlated with this defense of private property is a sense of the social demands on private property that come from the common good and the communal purpose of all earthly goods.  相似文献

This paper finds a high correlation between the open to close returns for U.S. stocks in the previous trading day and the Japanese equity market performance in the current period. In contrast, the Japanese market has only a small impact on the U.S. return in the current period. High correlations among open to close returns are a violation of the efficient market hypothesis; however, in trading simulations, the excess profits in Japan vanish when transactions costs and transfer taxes are included.  相似文献

Abstract. The topic of deferred income taxes has generated considerable controversy. This paper observes that much of this controversy centers on the contingent nature of income taxes. It reviews the similarity between the firm's income tax liabilities and a European call option written on the firm's pretax value. From this perspective, deferred taxes are shown to effectively alter the exercise price of the call option held by the government, thus affecting the value of the firm's debt and equity claims. Additional results are obtained from the model by valuing the tax liabilities and the firm's financial claims via an exact option pricing formula. Finally, the paper shows that the model is robust to some of its underlying assumptions. Résumé. Les impôts sur le revenu reportés ont été l'objet d'une immense contraverse. L'auteur fait remarquer que cette controverse est en grande partie centrée sur la nature conjoncturelle des impôts sur le revenu. Il examine la similarité entre la dette fiscale de l'entreprise et une option d'achat européenne libellée sur la valeur avant impôt de l'entre-prise. Dans cette perspective, l'auteur démontre que les impôts reportés modifient effectivement le prix d'exercice de l'option d'achat détenue par le gouvernement, infiuant ainsi sur la valeur des droits à l'actif de l'entreprise. Il obtient des résultats supplémentaires du modèle en évaluant la dette fiscale et les créances financières de l'entreprise par l'intermédiaire d'une formule de détermination du prix exact de l'option. Enfin, l'auteur démontre que certaines des hypothèses sous-jacentes au modèle résistent à l'analyse.  相似文献
