Why is there a difference in the following:
if you increase the duration of the 28million from 0 (ie cash) to (6) and then transfer the remaining balance portfolio (96 million) from 7.2 to 6.
resulting in 67 contracts to buy
OR
if you increase the duration to the 28 million from 0 to 7.2 and then transfer the whole balance of the portfolio (126 million) from 7.2 to 6.
resulting in 63 contracts to buy
