Cash balance retirement account
My company funds a cash balance retirement account. The yield is indexed from t-bills, I believe. The rate of return is actually quite low. Where would be the best place to put this? The other part of my retirement account has my 401k and Roth IRA. Lumping the cash balance in the retirement would give it a much higher rate of return than it should have. The cash balance is around $4k a year, with the 401k and Roth IRA around $18k per year, so the cash balance is not insigificant.
Should I just create a portfolio for the Monte Carlo simulation that has the weighted yield, i.e. it would include a cash % equivalent to my cash balance retirement account?
Is there a way to do this without running a Monte Carlo? I am just learning and it will take awhile to get confidence to try the MC.
