My only point is that it is those big negative "averages" that will slay ya if you are just gettin out of the market to retire.
I enjoy discussing financial options but would never recommend making decisions based solely on information gleened from the internet. To me retirement planning invoves more than just putting money in a mutual fund 401k.
Thirty or more years ago I took a great continuing education financial planning seminar at a local high school. I have been very happy with the results of that decision.
If you been in for the long haul odds are your investments will have appreciated . Now one could quibble over the difference of of a 5% appreciation v. a 10% appreciation when one chooses to get out but the bottom line is it's still a gain.
The role one plays in an investment strategy, be it an active or passive role, is up to the particular investor. it's a fair assumption most would choose a passive role and leave it up to fund managers to direct the particulars of what stocks/bonds are in play.
Also unless an individuals income changes often in essence their investment would be dollar cost averaging to lower the total average cost per share of the investment, giving the investor a lower overall cost for the shares purchased over time balancing return and risk.
