I am wondering how much (if any) of my liquid assets should be in a money market account.
It's worth mentioning that I think this varies a lot based on how big your portfolio is. For example, you could make the case that for someone with $5k in assets, $2k should be in a money market account, $2k in other investment instruments and $1k in cash, but maybe your viewpoint is that for a portfolio of $100k only $4k should be put into a money market account.
If you can answer this question for varying portfolio sizes I think that might be helpful for other readers.
To make the question easier to answer, let's assume you expect to grow your assets by 20% this year (i.e. your expected revenue - your expected expenses is equal to 20% of your current portfolio value). So from this, you can safely say that your revenue meets your expense needs with some wiggle room.
