Implementation Shortfall Q10/Read41/Pg333 (vol5)

Problem B - why is the benchmark price = 53.25? could find it in the text in terms of how to determine benchmark price. isn’t benchmark price usually given??? if not given what’s the usual way to determine it? thanks

i was about to ask about this problem. this is part B, ques 10 instead of implementation shortfall, they seem to have calculated effective spreads using midquotes. anyone?

nobody had the same query?

53.25 is the benchmark price. it is calculated as the midquote in this case.

thanks bill, but where doesn’t it say in the text regarding how to get the benchmark price?

unsolved puzzle…
