Okay. I didn't see 2.71% in that article and I'm always skeptical if a hard, precise number claims to rely on a "high PE ratio". I'll have to dig in deeper when I have the chance.
Thanks.
I dug deeper and I realized that the SWR I quoted was derived from the SWR Toolbox spreadsheet: 60/40 stock/bond, 720 month retirement and 100% final value target few years ago. The 2.71% was in the table "SWRs to target different Failure Rates" for the cell J18 (CAPE>30 and 0% failure rate). The SWR number in J18 cell (as of today) has gone up to 3.11% with the same assumptions. The assumptions DO change the SWR but only slightly and all the results hover around 3% for 100% success rate.
