Thoughts on Asset Deployment for Early Retirement
So, heading into what I hope is the home stretch I decided I needed to decide on a target portfolio strategy for the early years of ER. For giggles I thought I'd lay it out here. As usual for me (financially) I'm staying pretty vanilla/conservative.
I've considered a variety of relatively common solutions to arranging assets for withdrawal phase. The idea I always seem to come back to is a liability matching portfolio (LMP) strategy. It requires an estimate of "liability" which is basically just an estimate of total future portfolio withdrawals. The basic idea is that an amount of the portfolio sufficient to cover the liability is dedicated to stable assets, and the balance of the portfolio can then be invested in a variety of ways to meet other considerations/goals a person might have.
I maintain a spreadsheet that among other things calculates my total expected withdrawals under a variety of situations/conditions. It's fluid in the sense that I update it regularly (and play different scenarios) so things change. But under the conditions I feel I'm most likely to encounter total withdrawals range between about 17% and 22% of my (estimated) portfolio total on the day of retirement.
My wrinkle to the LMP is that I want to dedicate 2X my anticipated total withdrawals to my stable asset liability match, so something around 35% to 45% of my portfolio at retirement. I chose 2X somewhat arbitrarily to pad the number in case I wind up with a little more growth in lifestyle spending than what I am already planning on, or inflation runs a little higher (devalues pension faster), etc. It also has the appeal of giving me an overall asset allocation (AA) that would be limited on the aggressive side to 65/35 even if all my non-liability-covering assets were sunk into stocks.
I'm planning to go with intermediate-term bonds for the lion's share of the liability match. There is some interest rate and inflation sensitivity with them, but barring Armageddon, with 2X the liability invested, it should work out okay. Some people like TIPS and/or I-bonds for this, but I'll likely just go with a broad aggregate index. That's in good measure due to convenience because it matches what I have available in my 401k plan.
So what about the rest of the portfolio? The uses I've contemplated are:
- a giant emergency fund,
2. resources for any YOLO splurges that might become attractive in the future
3. legacy for heirs
I like all three. Since I expect there will be a pretty significant amount in this pile (probably > $500K, maybe significantly so), and my basic needs and entertainment are covered by the liability match, I don't see a strong argument against investing this remainder for medium-/long-term growth in stocks.
Therefore, depending on how things go over the next couple years, I'll be working towards shifting my AA to something between 55/45 and 65/35. That puts me in the heart of the Trinity Study AA-space so one might ask why bother with the LMP view. It's a fair question and my only answer is that to me it just feels right to start where the rubber meets the road (how much I spend on an ongoing basis and how that projects looking forward in time) and use that to arrive at an AA.
I do not plan on any sophisticated or formulaic withdrawal strategies. I'll start with whatever distributions my taxable account throws off, and when necessary I'll sell assets based on what seems to make sense at the time. Tax ramifications, recent market performance, my age, AA drift, and RMDs will all factor into the decision at times. If things go benignly I’ll have an average withdrawal rate under 2%, so I don’t believe the
how of the withdrawals to be critical.
