Set forth below is the text of a comment that I recently posted to the discussion thread for another blog entry at this site:
What I proposed in my post of the morning of May 13, 2002, is that we look at the second calculation. “
Is this the proposal you are referring to?
https://boards.fool.com/price-adjusted-safe-withdrawal-rates-17209214.aspx?sort=whole
And here is the relevant quote
“What I am thinking would be useful is a calculator that allowed you to choose three options: (a) a purchase at a time period in which stocks were priced low, using the conventional valuation criteria; (b) a purchase at a time-period in which stocks were priced about average; and (c) a purchase at a time-period in which stocks were priced high. After entering your choice of (a), (b), or (c), <b>the calculator would tell you what sort of long-term safe withdrawal rates were provided to other investors investing at similar price levels obtained in earlier historical periods.</b>
My guess is that such a calculator would show an investor investing during a time when low stock prices prevail would be likely to obtain a safe withdrawal rate higher than the 4 percent return that the conventional calculators (those using all investment price levels in their data set) suggest. Presuming that we see such prices again in the future, that would allow people with money to invest at that time to retire with confidence of obtaining a long-term safe withdrawal rate greater than the safe withdrawal rates suggested by the conventional calculators (higher than the 4 percent figure we often hear cited on this board, that is).
On the other hand, it would show a lower safe withdrawal rate for investors putting money into stocks today. Personally, I would be willing to accept a safe withdrawal rate assumption of less than 4 percent, given the low rates paid by safe investments like ibonds today. However, if the modified calculator showed asafe wtthdrawal rate for stock investments made at today ‘s prices of less than 2 percent, my inclination would be to go with ibonds or some similar investment.”
Those words offer a very good overview of the issues that I believe we all need to be examining. I have learned a lot as a result of the last 20 years of discussions. So I don’t know that I would sign on to every word of the post today. But I believe that the part that you quoted does a great job of pointing to the sorts of trade-offs that should be considered.
This is not a situation where someone is going to craft a perfect three-sentence statement and that is going to be the end of it. The effect of valuations on long-term returns affects every strategic issue. We need to have thousands of people making contributions from thousands of different angles and we all need to be learning from those contributions and adjusting our own takes as we go. I have better formed views today than I did at the time I wrote those words. But I certainly don’t think that I today know it all. I want to continue learning. For that to happen, we need to make everyone feel 100 percent free to post their honest thoughts.
That’s where I am coming from.
