So lets say MF did an arbitrage by buying the stock in cash at 100 and selling futures at 101 and the future went into discount and hence the futures become 99. MFs will actually square up their position (or make MTM profit). (8/n)
Right now futures is @ 99 & cash @ 100 & hence MF cant do arbitrage. 2 make money they have to sell cash@ 100 & buy futures @ 99. Buying futures @ 99 is okay but the fund can’t sell stock in cash @ 100 bcoz they don’t have stocks 2 give delivery(10/n)
