Abstract
We examine the effects of insider trading on the stock price determination and its informational efficiency, when the market maker observes two, correlated, signals of the value of the firm. We show that the stock price is more informative and the insider’s profits are lower than when the market maker only observes the order flow, as in Kyle [Kyle, A., 1985, Continuous auctions and insider trading, Econometrica 53].
