June Rutherford is preparing a research report on Andronicus Fund, an offshore hedge fund that specializes in identifying market pricing inefficiencies and profiting from the arbitrage opportunities they present. Rutherford includes these statements in her report: Statement 1: The rate of return that investors require from Andronicus should reflect the risk that the fund managers will not consistently capture positive abnormal returns from the anomalies they have identified. Statement 2: Arbitrage trading is unlikely to bring about fully efficient prices because Andronicus and other arbitrageurs will not trade if the gains to be captured are less than their transactions costs.
