To Trade or Not to Trade: The Strategic Trading of Insiders around News Announcements

We argue that insiders' decisions to trade in short windows before news announcements are likely to result from a trade-off between the incentives to capitalize on the foreknowledge of the disclosure and the risk of regulatory scrutiny and lost reputation. We provide evidence that insider buying is driven by the trade-off, while selling is primarily influenced by the deterring effect of the regulatory and reputation risks. We show that insiders strategically choose the amount of shares bought ahead of good news announcements. They increase their purchases as the price impact of the news goes up, but we find that the amount of shares purchased levels off as the news becomes extreme. In contrast, we find that the probability of insider selling significantly decreases with the price impact of the forthcoming bad news. To further support our arguments on the importance of incentives and disincentives to trade, we show that the strategic trading is mainly observed in the most price-sensitive groups of news announcements, it is clearly pronounced for best informed executives (CEOs), and that trading patterns change with changes in regulations, and insiders with higher reputation at risk limit their trading ahead of bad news.insider trading, private information, information disclosure, regulation

Durability, Re-trading and Market Performance

Key differential structural characteristics of environments studied in previous market experiments have documented large divergences in their observed performance, particularly discrepancies in their convergence to expected equilibrium outcomes. We investigate why this should be so. The type of competitive equilibrium where a market clears at a particular price as initiated by Arrow and Debreu (1954) has long been studied in the laboratory. We refer to these experiments as Supply and Demand (SD) experiments. SD experiments are highly reduced in form: items are not re-tradable, buyers and sellers are specialized in these roles, and no second commodity, cash, is used as a medium of exchange, although cash enters as a numeraire qua reward incentive for subjects. Markets with these features that are repeated over time converge rapidly to the predicted equilibrium under a regime of strict private dispersed information on individual values that define the equilibrium predictions. In contrast, consider asset markets, in which shares can be freely re-traded against cash within and across periods, shares have well-defined common values based on common public information on expected cash “dividend” yields, and individuals are not specialized as buyers or sellers. These markets produce price bubbles that converge only with experience across repeat sessions. The prospect of re-trade, and perhaps the lack of buyer/seller specialization, results in market behavior that contrasts sharply with the perishable goods that characterize the SD experiments. Building on this background analysis we report new experiments that combine features of both environments and initiate an investigation of how commodity durability that constrains re-trading characteristics affect the observed variation in market performance.

Buy it now: A hybrid market institution

This paper analyzes seller choices and outcomes in approximately 700 Internet auctions of a relatively homogeneous good. The ‘Buy it Now’ option allows the seller to convert the auction into a posted price market. We use a structural model to control for the conduct of the auction as well as product and seller characteristics. In explaining seller choices, we find that the ‘Buy it Now’ option was used more often by sellers with higher ratings and offering fewer units; and posted prices were more prevalent for used items. In explaining auction outcomes, we find that auctions with a ‘Buy it Now’ price had higher winning bids, ceteris paribus, whether or not the auction ended with the ‘Buy it Now’ offer being accepted, possibly reflecting signaling or bounded rationality. We also find that posting prices, by combining ‘Buy it Now’ and an equal starting price, was an effective strategy for sellers in the sample.Market institutions; posted prices; auctions; e-commerce

Critical Market Crashes

This review is a partial synthesis of the book ``Why stock market crash'' (Princeton University Press, January 2003), which presents a general theory of financial crashes and of stock market instabilities that his co-workers and the author have developed over the past seven years. The study of the frequency distribution of drawdowns, or runs of successive losses shows that large financial crashes are ``outliers'': they form a class of their own as can be seen from their statistical signatures. If large financial crashes are ``outliers'', they are special and thus require a special explanation, a specific model, a theory of their own. In addition, their special properties may perhaps be used for their prediction. The main mechanisms leading to positive feedbacks, i.e., self-reinforcement, such as imitative behavior and herding between investors are reviewed with many references provided to the relevant literature outside the confine of Physics. Positive feedbacks provide the fuel for the development of speculative bubbles, preparing the instability for a major crash. We demonstrate several detailed mathematical models of speculative bubbles and crashes. The most important message is the discovery of robust and universal signatures of the approach to crashes. These precursory patterns have been documented for essentially all crashes on developed as well as emergent stock markets, on currency markets, on company stocks, and so on. The concept of an ``anti-bubble'' is also summarized, with two forward predictions on the Japanese stock market starting in 1999 and on the USA stock market still running. We conclude by presenting our view of the organization of financial markets.Comment: Latex 89 pages and 38 figures, in press in Physics Report
