You Cannot Be a Hundred % in Stocks

i did a target retirement fund for both the four one k and the ros. Since i'm not a big expert on what that should look like, i might lumi just get a target date fund,. I think that that's perfectly reasonable to have some money in stock, some money and bonds. And if you say, i don't really know what i'm doing, or i don't want to have to deal with it, target date is fine. Where is the four o one k held? What big organization?
