Today I deposited an additional $10K in my account, bringing my total assets under management to roughly $166K (of which $62.5K is cash, so I'll be looking to put some of it to work). Obviously this won't impact my IRR calculation - after all this is simply an increase in AUM and not appreciation/depreciation of the stocks/options I hold.
Additionally, since I track my returns relative to the S&P, I'll need to update my hypothetical S&P portfolio to keep everything on an apples-to-apples basis. To do this I simply assume I purchased $10K of the SPY index fund at today's closing price of $127.02, thereby creating a similar growth in AUM.
