Far be it from me to interrupt your successful retirement portfolio. The only concern I have is whether you have other money outside your retirement plan — money that you could use for living expenses without being forced to sell any of your funds in a bear market. You will need to start withdrawing in about 5 years, taking RMDs. Keep that in mind. You might consider doing a rollover to a place like Fidelity or Vanguard — where you will get a wider variety of investment options. Company 40l(k) plans are designed with long-term growth in mind; you now need to also consider capital preservation.
