If you know one formula - then you will get the right answer作者: Iginla2011 时间: 2011-7-11 20:09
you mean the midpoint thing? Theyre just saying if presented with a bid ask spread instead of a price benchmark to use the midpoint as your benchmark.作者: aidebaobao 时间: 2011-7-11 20:09

I was struggling with this one.作者: oneboy 时间: 2011-7-11 20:09
I don't know if you guys remember, but I was doing an IS problem, where the securities were purchased at different prices and they used the average prices of the purchase to calculate the realized profits/losses.
Any idea where this was? I think it would have been in one of the Schweser exams, not sure.
But is that concept right? Or do we have to calculate the realized profits individually for each purchase price?作者: wake2000 时间: 2011-7-11 20:09
No. I do not believe so. There are two previous closing prices- if I recollect correctly.
Problem specifically states which one to take.作者: cityboy 时间: 2011-7-11 20:09
Hey thanks DS. Quick question, ifyou dont mind, so if we are averaging the prices for calculation of RP/RL, would we also average the prices for the delay costs? as this would also involve two separate delay costs if they are made during a span of a couple of days.
