(a) Assuming a 365-day year, compute the holding period yield (\%pa to 2 decimal places) for an investor that bought a $10m face-value, 90-day bank bill on July 17 and sold it 7 days later on July 24 (assuming the yield for a 83-day bill is the same as that for a 90-day bill). (b) Why does the computed HPY differ from both the yeld prevailing on July 17 and the yield on July 24 ?
