Consider a sequential trade model in which a security has an uncertain value. The value V of the security can either be $150 or $250 with equal probability. The proportion of informed traders is 60%, whereas the proportion of liquidity traders is 40%. As usual liquidity traders buy or sell with equal probability, whereas informed traders only buy when they know the security price is high, and sell when they know the security price is low. The conditional expectation of V, conditional that the first trade is a buy, is: o a E[V | Buy]-170 Ob EV | Buy]-180 C. EV Buy]-200 od EV Buyl - 220 o e.EV | Buy]-230 f. None of the above
