Asymmetric Attention and Stock Returns

چکیده
This paper constructs a new measure of attention allocation by local investors relative to nonlocals using aggregate search volume from Google. We first present conceptual framework in which optimally choose focus their on stocks when they receive private news, leading an asymmetric between and nonlocal investors. Consistent with the main prediction this framework, we find that firms attracting abnormally high earn higher returns. A portfolio goes long short low has alpha 32 basis points per month. The results are stronger for greater degree information friction. allows one infer arrival unobservable observing investors’ behavior. was accepted Karl Diether, finance.

Stock Returns, Implied Volatility Innovations, and the Asymmetric Volatility Phenomenon
We study the dynamic relation between daily stock returns and innovations in option-derived implied volatilities. By simultaneously analyzing innovations in index-level and firm-level implied volatilities, we distinguish between innovations in systematic and idiosyncratic volatility in an effort to better understand the asymmetric volatility phenomenon. Our results indicate that the relation be...
متن کاملIdentifying common spectral and asymmetric features in stock returns
This paper proposes spectral and asymmetric-volatility based methods for cluster analysis of stock returns. Using the information about both the periodogram of the squared returns and the estimated parameters in the TARCH equation, we compute a distance matrix for the stock returns. Clusters are formed by looking to the hierarchical structure tree (or dendrogram) and the computed principal coor...
متن کاملAsymmetric Correlation of Stock Returns: Statistical Tests and Economic Evaluation
In this paper, we provide a model-free test for asymmetric correlations which suggest stocks tend to have greater correlations with the market when the market goes down than when it goes up. In addition, we evaluate the economic significance of asymmetric correlations by answering the question that what is the utility gain for an investor who switches from a belief of symmetric correlations int...
متن کاملA Study of Search Attention and Stock Returns Cross Predictability
This study investigates a novel application of correlated online searches in predicting stock performance across supply chain partners. If two firms are economically dependent through supply-chain relationship and if information related to both firms diffuses in the market slowly (rapidly), then our ability to predict stock returns increases (vanishes). Using supply-chain data and weekly co-sea...
متن کاملInflexibility and Stock Returns
Investment-based asset pricing research highlights the role of irreversibility as a determinant of firms’ risk and expected return. In a neoclassical model of a firm with costly scale adjustment options, we show that the effect of scale flexibility (i.e., contraction and expansion options) is to determine the relation between risk and operating leverage: risk increases with operating leverage f...
