A hedge fund has a position in 1 million shares of a stock whose midprice is $100. The bid-ask spread is $0.40, up to a volume of 100,000. Beyond that, prices fall by $0.50 per share for every 100,000 shares transacted in one day. Compute the loss from the midprice if the entire position is liquidated over 1 day. This should be computed in dollars and in fraction of the initial position value.
