Yes. Not making a mistake - not selling at a market bottom. But again in a "never sell" mentality which is the case if WR is down at the dividend yield rate.... That won't happen. Much bigger risk is inflation even at 2 percent will erode principle and your bond face value amount over the long term
Recall here that we are fired and so not in accumulation phase. Money is either in the left pocket in equities or right pocket in bonds. No new money flowing into either pocket. (Assume we are spending the dividends or coupons to live off of).
So aside looking at the account balance at a particular point in time, being in your 40s meaning you hope to live another 40-50 years, I don't see why one would limit their upside potential of principle by being in bonds at such a young age, especially when yield covers expenses. Just live on that yield/ dividends, wait for the market increases.... It always does. At least in modern times. The daily monthly or yearly fluctuation doesn't matter much.
That's a better shot than buying bonds, holding to maturity, earning a return that barely covers long run rates of inflation but having to spend it to live on. At the end of 40 years and having spent the bond coupon /interest, you're left with dollars returned that are seriously devalued due to inflation. Your principle is intact but it's worth way less ... Equities at least have a fighting chance over the long term to increase your principle return equal to or maybe a little beyond inflation.
Long term , equities simply outperform.
So .... With such a long time horizon, why the conservatism? Unless the reality is one needs to spend principle too... Early on in retirement. Like during the 50s or early 60s.... Or If dividends are at risk...or the actual WR is moving higher than just the dividend yield due to lifestyle spending creep.
Otherwise I just don't get it. Perhaps it's the sleep at night factor that I'm missing.
Or the desire to draw down principle and buy that big house/car/yacht etc at a moments notice rather than treat the principle sorta like a permanent and untouchable investment with a stream of cash flows like an annuity .
I see a different scenario toward older age where you may have huge expenses for health care beyond dividend yield amount and need that principle. That's when you might want or need some bond assets or cash - in 60s and 70s ... And then SPIA in 80s for longevity insurance.
Good discussion. I historically was overly conservative but have changed my habits over time... Maybe I'm overly aggressive now holding just stocks in broad market funds and some cash ...
Early early retirement is truly unique with long long time horizons to manage, little if any safety nets such as defined pensions , and even uncertainty about SS...
