The market portfolio plays a special role in asset pricing. Although many finance researchers use a U.S. equity portfolio to proxy for the market portfolio, theory usually dictates a broad, world portfolio that includes global equities, global real estate, commodities, and fixed income. In a new Review of Asset Pricing Studies paper, “Historical Returns of the Market Portfolio,” Ronald Doeswijk, Trevin Lam, and Laurens Swinkels introduce the best proxy for the global market portfolio to date. Since 1960, this portfolio has delivered a realized annual compound return (in U.S. dollars) of 4.45%.  Their index and its components may be downloaded for free.

Paper Spotlight: Do Proxies for Informed Trading Measure Informed Trading? Evidence from Illegal Insider Trades

Kenneth Ahern

Reliable proxies for informed trading are required to test many theories in finance. Theory suggests several possible proxies; however, validating these empirically has been challenging because trades by informed investors cannot (in general) be observed. Kenneth Ahern’s new paper, “Do Proxies for Informed Trading Measure Informed Trading? Evidence from Illegal Insider Trades,” addresses this challenge by using hand-collected data on illegal insider trades. He shows that the effective bid-ask spread and the absolute order imbalance are robust predictors of informed trading (illegal insider trading) while other measures are not because of strategic timing of their trades by insiders and sampling bias.
