The LPs contributions, in this case, contribute to the IRR?? I don't think that should be the case (note: the contributions are not dividends from investments: they are LP's aum)

I intended to compare the IRR for this fund with its TWR. The TWR formula (from a third party) considers market value (i.e., unrealised gains). So if my IRR doesn't consider unrealised gain... I really can't do any comparison. Do you think that TWR shouldn't consider unrealised gains either?.. or should I, when reasoning abt an investment vehicle, capture unrealised gains in the IRR calculation @noob2?

@noob2 Thanks for your comment. But if the IRR doesn't consider the unrealised gain, it conveys very little info for a fund that made capital losses/gains isn't it? What would be a more informative metric in this case?

Edited, thx for this q @whisperer

thx. You are right: the formula for the portfolio wasn't correct. I edited it now. So what is the formula for the general case then?

Thanks. In this case, what is the contribution of asset A, say, to the portfolio's total tracking error?
