Drawdown calculation

The drawdown calculation is pretty easy, (trough value - peak value)/Peak value.

However, when a fund has cash inflows and outflows, how do you adjust the drawdown reflecting the cash inflows/outflows? Thanks.

Oops, this should be a Level 3 question.

Dude what are you talking about?

You know when you calculate drawndowns in your portfolio, do you need to adjust it for cash inflows/outflows? If needed, how would you do that? thanks.

e.g.

day Portfolio value Cash Inflow(out) Drawdown

1 100 0 - 2 101 0 0 3 99 0 (99-101)/101 = -1.98% 4 100 1 (100-101)/101 = -0.99% But this is wrong, since there is 1 cash inflow

Do we need to adjust cash inflow/outflows for drawdowns?

This simplified example is quite easy to adjust but when you have a dynamic mark-to-market portfolio with millions of cash inflow/outflows per day, it gets so complicated. This is more like a question for portfolio managers and fund accountants.
