ladelfina - Good question!
I voted 50% in the poll after reading about typical investment approaches with typical mutual fund houses. The John Bogle article "The Relentless Rules of Humble Arithmetic"
http://www.vanguard.com/bogle_site/sp20060101.htm elegantly steps through the process of starting with the values of the underlying stocks in the market and subtracting expenses, overheads, and unfortunate buy/sell decisions that lead to reduced "Average Investor Gains".
- The best you can have is the basic stocks and their dividends for an actual market return value.
- If you have these stock within a mutual fund at a vendor (such as Vanguard or Fidelity) your return would be reduced by the ER and some other associated trading costs and overhead, and also by advisor fees. As a result you, as the mutual fund owner, would receive typically 93-98% of the actual market returns of the underlying stocks.
- If you then chose to attempt to market-time and move in-and-out of the market at inappropriate times, then your transaction costs, etc could reduce your actual market returns even more. Bogle says that the typical MF owner realizes 60-65% of the actual market returns.
What I found most significant in the "...Humble..." article above, was the systematic expenses associated with having your funds with different vendors; Bogle indicates that merely buying your funds from different vendors can change your returns within a range from 98% to 36% of actual market returns of the underlying stocks.
I've learned many things here - if you have a stable asset allocation in mind, buy etfs instead of mutual funds, stay the course, chose a low cost vendor and keep away from advisors.
Great poll Hellbender!
