Always ran a 100% aggressive equity allocation (VTI/VOO and a chunk of VXUS). I’ll have a pension so I always looked at that as being a substitute for fixed income assets in my overall retirement plan, and felt liberated to go all-in on my current mix.
Wanted to add just dash (1-2%) of bond/fixed income to my above index ETF) portfolio. Reasoning: i’m at early retirement age now, I’m planning to continue work for wthe next 5 to 10 years, but layoff and health problems happen and retirement could be forced early. There would be a leg for my actual retirement until a pension kicking in so the fixed income slice would cover that gap until the pension started.
