Great thread! I have been thinking about this topic a lot lately.
If we are talking about asset allocation in a complete vacuum, I agree with some comments that suggested being in at least 75% equities, in order to generate the returns necessary to support FIRE, per the Trinity study. I think an allocation at least this aggressive is necessary in the wealth accumulation phase and the “early retirement” phase, for the 4% rule to work.
Under FIRE, one would not make their asset allocation more conservative than 75/25 (toward bonds) unless they had enough excess capital to be able to withstand smaller (but more consistent) returns. This is why some folks suggested playing with different calculators and spreadsheets, to see what works for you.
In my personal experience, for myself, I do not think of my asset allocation in a vacuum. Of my investments, my DH and I are at an 83/17 split of stocks/ bonds. But our investments represent just 50% of our net worth. The other 50% of our net worth is in our primary residence equity, a pension (actuarial present value), and cash. I think that makes my allocation way too conservative overall, especially given that DH and I are both still working. My goal for 2019 is to get our investments up to 65% of our net worth by increasing new contributions, and to get our investments up to 80% of our net worth by the end of 2020. And in the meantime, I would have no qualms about letting my asset allocation float up to 90/10 or even more aggressive.
If I were really close to FIRE, these things would impact my asset allocation:
- How much do I have in cash? How much do I want to keep in cash?
- What is my tax situation, given my income and my holdings/ unrealized capital gains? Could I easily sell equities for cash if I wanted to, without incurring penalties or taxes?
- Do I own my home?
- Of my planned spending, how much is fixed? How much is discretionary?
- Do I have any sources of income aside from my investments, especially fixed income?
- Is my spending even and predictable, or is it lumpy year to year?
- How is my health? What is my plan for access to health insurance and health care in early retirement? What does that do to my risk tolerance?
Stated another way: If I did not yet have a big cash cushion saved, but I had high fixed expenses like a mortgage, or unpredictable expenses like being on a volatile open market for health insurance, then I would be more conservative in my asset allocation. But, with the more conservative asset allocation, I would correspondingly drop my SWR a bit, or I would plan to withdraw less in years with bad performance (ie, accept more income volatility.). The overall effect is that I would need a bigger “magic number” to feel comfortable giving up W2 income in such a scenario.
Therefore, for me and DH, we have done and will continue to do things that improve our financial security, rather than get too wrapped up in a specific asset allocation. Some of our plans and actions to address security and risk include::
- DH staying with his current state employer even if he could get higher salary elsewhere, because when he reaches 25 years of service he can access health insurance for the current employee premium cost, even once he retires. This benefit is pure gold for us.
- Aligning our mortgage payoff date with our target retirement date by making some early mortgage payments now, so our expenses will drop in RE.
- Increased cash balances to cover 1-year of expenses after we bought our home, even though it meant pausing non-retirement investment new contributions for 18 months
- Of our 83/17 overall asset allocation, put the riskier holdings in retirement accounts and more steady holdings in taxable brokerage accounts. For example, in percentage terms, I hold more international index funds in my Roth IRA, and I hold more S&P index in my taxable brokerage account.
Currently, I hope to FIRE in 2022 at age 38, and still plan for my husband to FIRE in 2036 years at his age 54.
