I recently came I to unexpected money. I am working with a broker but need some help deciding what to do. I am looking to put 400k into an 80/20 stock to bond portfolio, 50k Roth, and about 200k into a money market. This does make me nervous because I don't want to lose the money, but I would like to retire in 15-18 years or so. Does this seem like a large risk, and should I diversify the money better?
