My mom's CFP did use some sort of questionnaire back in the late 2000's and arrive at 40/60 stock/bond. She eventually drift to 30/70, so he wasn't too far off.
Personally, I started with 100% stock allocation, which I carry until about 5 years ago, where I then started to shift to a more 70/30 position. My reasoning is that I needed those bonds to smooth out the decade to decade returns now that I am closer to retirement and also because my portfolio is grown to a size where I am unable to contribute enough to affect the recovery.
In the past, there have been things like age in bonds, but for some reason that seems less prevalent these days.
What are the ways you arrived at your numbers? What drive that numbers, is it some sort of stats or is it emotional? Part of my curiousity is if you arrived your numbers from an emotional sense or a more systematic path? My particular conclusion comes from
- 30% is about 10 years of expense assuming your portfolio is for 30 years. I don't think we have had a 10 year bear market.
- The Monte Carlo numbers show that I only have slightly reduced return for the next 10 years for going with 70/30 over a 100.
- Backtesting over some bad time period like 1972-1981 (high inflation) and 2000-2009 (Dot Com bubble and Global Financial Crisis) shows a more acceptable numbers for 70/30.
- Unlike most people I am not too concern when my portfolio loses 50%, but I recognized that we may hit a period like 2000 where stock recover slowly.
- My contribution is now about 2-3% of portfolio even when maxed out, this is not enough to speed up recovery.
