Getting the benchmark right is certainly essential

The question of attributing by volatility is an unusual one, and I don't think there is any agreed...

Confusion reigns

Hi Fook Seng,

I think that most people agree with the proposition:
IF the manager does not control the cashflows THEN it is preferable to use time weighted returns
(IF A THEN B).

I know that some...

You need to use exposure in the denominators

Hi,

May I ask whether you are doing these calculations in a spreadsheet?

I am soon going to publish a paper on this topic.

In the meantime, you may find it helpful to read the material about...

Kramer,

If the portfolio is valued monthly (and hence you only know the NAV at month end), but the cashflow takes place during the month, you will not be able to calculate a completely accurate...

The first point to not is that if there were no dividends, all you would need is the NAV at the start and the NAV at the finish. This would give you the return over the entire period. For example,...

Hi Kevin

The difference between time-weighted and money-weighted is a very basic one, but it also is a question on which some self-professed experts are totally confused and totally wrong.

Do the attribution on gross returns

So far as I am aware, the most common practice is to say "Here is the gross return, here is an attribution analysis showing how gross differs from benchmark, and now separately I will show...

The decision of whether to use a hedged index is normally part of deciding what the benchmark is. Plenty of managers have a global equities (unhedged) product, and a global equities (fully...

Looking back at Andy's original question, may I add that if you don't treat this as a spacial case in the attribution analysis, you can get some unhelpful results.

Performance attribution with zero-weighted sectors

It would appear that the most common usage of this term is as David and Carl have described, i.e. attribution including a sector that is not present in the benchmark.
My terminology about this is...

Two options

You have two options:
1. Use a sector attribution model, and classify the securities into different groups according to the styles you want to analyse. See an article I wrote on "Flexible...

If you have the inputs, the calculation is trivial
