Back to that couple’s 60% / 40% portfolio. It’s now in a three fund portfolio, or the closest thing we could get to one without realizing capital gains unnecessarily, but before that, they had 28 funds (26 mutual funds and 2 ETFs).
Six of those funds had expense ratios of over 100 basis points (1%), whereas most index funds are in the 0 to 10 basis point range. The average expense ratio of the funds this couple owned was 0.67%.
