This study proposes the dispersion in daily net initiated order flow across brokers as a proxy for the level of noise trading in a stock, and applies this proxy to test some basic implications of market microstructure theory. We use data from the Australian Stock Exchange, a computerized limit order market where price, quantity, and broker identity for each incoming order are shown on broker sc...

In a market with short term agents and heterogeneous information, when liquidity trading displays persistence, prices reflect average expectations about fundamentals and liquidity trading. Informed investors exploit a private learning channel to infer the demand of liquidity traders from the order flow to anticipate the evolution of the future aggregate demand for the stock. This yields multipl...

This paper analyzes models of securities markets with a single strategic informed trader and competitive market makers. In one version, uninformed trades arrive as a Brownian motion and market makers see only the order imbalance, as in Kyle (1985). In the other version, uninformed trades arrive as a Poisson process and market makers see individual trades. This is similar to the Glosten–Milgrom ...

Prediction markets are low volume speculative markets whose prices offer informative forecasts on particular policy topics. Observers worry that traders may attempt to mislead decision makers by manipulating prices. We adapt a Kyle-style market microstructure model to this case, adding a manipulator with an additional quadratic preference regarding the price. In this model, when other traders a...

Using a unique non-anonymous dataset, covering virtually all secondary market trades in the UK corporate bond market, we show that clients outperform when they trade with more dealers. The effect is stronger for informationally sensitive (holding CDS positions on issuer), assets (high-yield bonds), and during intensive days (macro/rating announcements). results are consistent varying number of ...

Recent research has documented empirical evidence of informed trading ahead of major corporate events such as earnings announcements, mergers and acquisitions and corporate bankruptcies. However, no such evidence exists ahead of corporate spinoffs (SP). Using a sample of 426 corporate SPs from 1996 to 2013, we document pervasive activity in options of the parent company, but not in stocks, that...

This paper investigates the effectiveness of a market surveillance system (MSS) on improving quality Vietnamese stock market, as measured by liquidity and informed trading level. We find that decreases after introduction MSS, effect is more pronounced for small firms. Although level trading, average, does not change significantly subsample analysis indicates significant decrease in among large ...

Dark pools are equity trading systems that do not publicly display orders. Orders in dark pools are matched within the exchange bid-ask spread without a guarantee of execution. Informed traders are more likely to cluster on the heavy side of the market and therefore face a lower execution probability in the dark pool, relative to uninformed traders. Consequently, exchanges are more attractive t...

We analyse the value of information in a stock market where information can be noisy and costly, using techniques from empirical game theory. Previous work has shown that the value of information follows a J-curve, where averagely informed traders perform below market average, and only insiders prevail. Here we show that both noise and cost can change this picture, in several cases leading to o...
