~2 years out assuming I can make it that long. Some days this site is primary source of sanity for me while at w*rk.
Currently at 55/0/5 (s/b/c) and the remaining 40 in rental properties. Planning to transition gradually to 85/12/3 after ER to minimize tax impact of divesting the rental property.
I think people stress about this way too much. Even 85% in retirement I think is fine, if you are Ok with it.
People will say they don't want to sell stocks in a downturn - OK, don't. Let's say your portfolio kicks off 2.5% in divs, and you need 3.5%. In a 10 year downturn, you only need to pull ~ 1%/year from principal. So pull it from the fixed income side, and even over 10 years, you don't need to sell any equities, and you'd still have some fixed income buffer left, even at a starting point of 85% equities.
-ERD50
Similar to @ERD50's thoughts, we have set a FIRE target WR of 3.5%. The 12/3 in short-term fixed income/cash plus dividends should conservatively allow at least 6 years before selling equities in a major market downturn. This "bookending" approach where AA is allowed to float within a range (even to 100/0 in a very bad market if necessary) and only rebalanced to a target of ~85/15 when times are good seems to have a lot of merit.
James Cloonan's newest book
Investing at Level3 has an example of this approach on pp 166-7. He ignores dividends, but does show how a year-end 80/20 AA (in a normal market, you start the year with 75/25) with a 5% WR (n.b., I do NOT advocate a 5% WR, but this was in Cloonan's example) would have survived in the 2008/09 recession and have recovered to the original value by 1/1/2013.
Here's a shortened version of Cloonan's example, scaled to an initial 1000 total portfolio value with S portion in an S&P 500 index fund, B portion in safe assets returning 4%, and yearly spend of 50:
Start of Year| S| B| Total
2008| 750* | 250 | 1000
2009| 473 | 158* | 762
2010 | 598 | 114* | 817
2011 | 688 | 69* | 775
2012 | 702 | 22* | 837
2013 | 675* | 112 | 1010
* indicates source of cash on Jan 1 for yearly spending
Haven't yet taken the time to look at other challenging historical periods.
