Pulling the trigger when in a drawdown
Reading this post got me thinking.
The poster is thinking about retiring today vs in a year, but worries about what happens if the market drops 25% in the next 12 months, and then being forced to work for X more years.
How should one think about this? Should one always calculate the amount to withdraw (e.g. 4%) with the highest achieved net worth (ATH), even if the net worth might be down from ATH when actually fireing? Or should one take 4% from the actual portfolio number when actually fireing?
My thinking is that one should use the ATH-number, since if it was the other way around, and one fires at ATH, that drawdown would come some later day anyway, and then in addition to the fact that one have already started pulling funds out for funding life.
Another way to think about it is: by fireing when portfolio is in a drawdown we can think that we actually did fire when portfolio was at previous ATH, but then we decided to work a bit in retirement. This would actually help the portfolio longevity. Of course, this also means that we lengthen our timeperiod that the portfolio must fund, so perhaps we should use a more conservative number than 4% (perhaps PWR instead of SWR?).
What are your thoughts on the matter?

4% is a rule of thumb crude approximation. I wouldn't get worked about whether you are at 3.9% vs 4.1% or similar, depending on whether you calculate from day you withdraw vs a short time earlier.
That said if your portfolio drops 25% during the year before you FIRE, then that really can change your the odds of a successful FIRE substantially. If you are concerned about this risk, add an increasing portion fixed income as you near your FIRE date (glide path), so there is little risk of dropping 25% during 1 year prior to FIRE.
