With respect Colm, that period happens to coincide with the longest uninterrupted bull market in global stock market history. Your personal good fortune hardly represents a sound basis for any prudent retirement plan.
Sarenco, you're right: I was lucky in my timing - but not that lucky. As recorded in my diary update of 7 January, my portfolio fell by 28% in 2018. The ARF fell 15%; other investments (including the AMRF) brought the average fall to 28%. The long-term returns quoted in my last post allowed for the 2018 result.
My general point is that, as
@Marc noted above, long-term income, not short-term security of capital, is the prime requirement for an ARF holder. (And by "income" I don't mean dividends; I mean the income derived from capital gains and dividends). Cash delivers a zero income, bonds aren't much better (possibly worse in the long-term). Good quality equities and real estate are the best bet for achieving a reasonable long-term return, especially considering that the expected lifespan for a new retiree is probably more than two decades when future improvements in medical science are allowed for.
The "sequence of return risk" has often been cited as an argument against high equity levels in a retirement portfolio. The risk is overblown. Any theoretical studies I've seen on this topic start from the false assumptions that (i) the pensioner withdraws a constant amount each year, and (ii) they cash investments equal to the amount withdrawn. Both assumptions are wrong.
If I do well in a year, I treat myself - bigger presents for the grandchildren, a nice holiday, whatever - but if I've done badly, I cut back on expenditure. That doesn't fit with the model, but it is the reality.
Theoretical models also assume that the only way to derive an "income" from an ARF is by cashing investments. Speaking once again from experience, that's just not true. At the end of last year, when market values were on the floor, I had to raise some cash, but I managed to do it without selling investments (or by selling very little). There is always a small cash balance in the portfolio. At the end of 2018 I ran it down almost to zero. That too is a significant departure from the theoretical model, which would have me cashing investments to meet income needs, even if I had cash in the portfolio.
If the model allows for withdrawals to be flexed (even slightly) in response to market returns, and also allows for "income" to be taken from the cash balance in the fund when markets are depressed (with the cash being replenished when market returns are good), I'm sure that the matrix
@Marc kindly shared with us would look quite different. As it stands, it should carry a health warning: "This matrix is based on artificial assumptions, which might bear no relationship to what happens in practice".
