I sort of expect that I'll stop growing my "assets under management" pretty quickly. If I'm getting 100% / year (a ridiculous thing to assume, but it's directionally accurate), then $1M being managed this way is plenty of annual income. With the annual risk level dropping as the overall portfolio continues growing (more cash means larger ability to ride out a large loss).
I think like many I'm in a place where I've got uses for a really big pile of money - in my case there are some businesses I'd like to buy in the utility sector and change how they operate
. An example might be Portland General Electric with a roughly $5B market cap - I would like the opportunity to be the primary decision maker for a utility, with myself as the shareholder I'm accountable to (or maybe a small number of fellow shareholders with a similar objective), to try to push the current utility business model aggressively into the renewable energy economy, and find out what that new utility business model might look like.
But short of that kind of significant business buying ability, this (made up example) $1M / year income is already a ridiculously large amount of income. So I'd bias towards having more and more cash build up rather than continually bigger positions and start doing something others would recognize as diversification. In my case, investing more in real estate via an outfit I found named Fundrise and have the extra build up there. Even as my wife and I are busy trying to give it away.
I do see the possibility of needing to opening 10k contract trades when position sizes just keep on growing. Somewhere in there we get a large account problem around getting orders to fill. Maybe we'll need a new thread for people to talk about the #SeriousFirstWorldProblem of getting big position sizes opened and closed.
