So we are fixing to put a substantial amount of money in Fidelity. We will eventually have about 75% Treasury bonds and 25% S&P 500 as we are getting ready to retire. I don't fully understand FDIC and the limit of 250K. Lets say you have 500K and open a Fidelity account investing all of it in bonds and index funds. I would only have 250K insured? Would I have to open another account like Charles Shwab and split the 500K between the two? We will be opening a joint account between me and my wife. Thanks
