Empirical distributions of Chinese stock returns at different microscopic timescales
We study the distributions of event-time returns and clock-time returns at different microscopic timescales using ultra-high-frequency data extracted from the limit-order books of 23 stocks traded in the Chinese stock market in 2003. We find that the returns at the one-trade timescale obey the inverse cubic law. For larger timescales (2-32 trades and 1-5 minutes), the returns follow the Student...
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...
متن کاملDemographics , Stock Market Flows , and Stock Returns ∗
This paper studies the link between population age structure, net outflows (dividends plus repurchases less net issues) from the stock market, and stock market returns in an overlapping generations framework. I find support for the traditional lifecycle models — the outflows from the stock market are positively correlated with the changes in the fraction of old people (65 and over) and negative...
متن کاملInternet Stock Message Boards and Stock Returns
During 1999-2001 more than 35 million messages about public firms were posted on Yahoo! Finance. This paper examines whether stocks with high posting levels also have unusual subsequent returns and/or risk. They do. Stocks with the highest level of posting have unusually high realized volatility and unusually poor subsequent returns. This remains true after accounting for the effects of the mar...
متن کاملStock Returns Distributions: The Emergent Behaviour of a Multi-Agent Artificial Stock Market
We present an artificial stock market in which simple trading agents enter an asynchronous double auction market to trade in a single stock. Beginning with a population of random trading agents drawing their bid prices from a normal distribution around the current price, we compare the statistical properties of the emergent stock price return distribution to that observed on a real price series...
