For my cash asset class, I pretty much dumped all my money into long term CDs. My net worth is divided almost equally into stocks, bonds, cash, and real estate. I didn’t plan for it to be this way, it just happened and I don’t mind one bit. I love real estate the most because I like having a real asset which is tangible, produces income, and provides a hedge against inflation. My second favorite asset class is cash.
Cash is the only true means of passive income generation. I literally don’t have to do anything for the interest income earned after I decide on a CD. It just compounds and automatically renews to another similar duration CD after the initial period is over. My goal is to generate five figures a month in interest income from my CDs by the time I retire.
