Can you expound on why you like passive index investing?
In short, KISS (keep it sweet and simple).
When I started mutual fund investing (back around 1988 or so), I did so through a financial planner who set my IRA with a market timing strategy. Supposedly, their strategy would get computer signals and know when to get in/out of the market. Market timing, of course is a whole different topic.
Then, I investigated load vs no-load and would buy those yearly book of fund rankings thinking maybe I could pick the best mix (all the while, having a full time occupation). This then lead me to end up own having about 25 different funds.
That was when I discovered, there's gotta be a better way.
With all those funds...there's still no assurance that having them will do any better than just going with an index fund, which makes things much simpler. That was when I decided to chuck all the funds I had and just go the indexing route.
With indexing, if the index goes up (or down) my investment just follows along. I don't have to worry about if the fund manager is good? Will he/she leave the company? Are the expense ratios too much?
Instead, I focus on my asset allocations, and rebalance then done and move on, keeping it sweet and simple. Also, a big plus is index investing keeps my emotions in check as I know that I won't do worst than the index as a whole.
The analogy is if I make par each time golfing, I'm always in the game (not on the top, but not the bottom either, I'll take that).
