a) thinks they can time the markets (change asset mix depending on current equity valuations) and

The latter does reveal a flaw in SWR - many of the lowest scenarios (the ones that determine the historical SWR) have seen situations where the pot shrinks to some low multiple of the annual withdrawal amount quite early in the historical period and then recovers, fine with hindsight but had you 'lived' that series of returns I can guarantee you that everyone would have reduced withdrawals when they saw their pot fall to such a low multiple so early and would thus have had some years where they actually drew less than what turned out to be safe.
If you're portfolio drops 50,60,70% of course you're going to alter spending habits, the SWR theory swims against the tide of human nature there. That's why threads like this are so interesting because what starts as a 5-10% drop and market timing ends up being panic selling. As the falls get bigger eventually everyone develops the fear of running out of money.Emotions asides, drawing a static "SWR" probably doesn't make financial sense either, using a dynamic withdrawal rate would likely deliver better results overall, see link I posted earlier. Obviously assuming you can cope with swings in income.But whatever, you need a plan which you stick to and which is designed to cope with big market swings, far bigger than those of the last 3 months, if you go changing your plan because of fairly normal markets movements eg Nov to now, how are you going to cope with a 40% drop?

If share prices are a random walk then this is wrong.
If they show some sort of 'reversion to mean' then there is a guaranteed winning strategy that an efficient market will arbitrage away by definition.I think....5 -

If share prices are a random walk then this is wrong.
If they show some sort of 'reversion to mean' then it is a wining strategy but if shares always 'revert to mean' then there is a guaranteed winning strategy that an efficient market will arbitrage away by definition.Indeed, although there is a difference between short term market timing and taking advantage of long term trends. For instance, the trend that share prices tend to rise over the longer term. If people didn't believe in that trend continuing into the future, they wouldn't invest in equities in the first place.It could be argued that techniques like prime harvesting are "market timing", as it says to only sell equities once they've risen 20%, but it's certainly not short term market timing, it's trying to take advantage of the long term market trend (ie that share prices rise) in a structured way which should reduce the volatility of the portfolio.

We're down 6.1% from last month, overall, but up 3.67% year on year.
We have the same pot now, as we did back in April 21, net of spends.
So no need to hit the cash panic button just yet!!!How's it going, AKA, Nutwatch? - 12 month spends to date = 2.60% of current retirement "pot" (as at end May 2025)2 -

I should hope so, as we only NEED £135,000 over the next 9 years, before DBs kick in, from a current portfolio of £615,000.
If the markets were to crash to that extent, I think we'd all have bigger worries!!!How's it going, AKA, Nutwatch? - 12 month spends to date = 2.60% of current retirement "pot" (as at end May 2025)1 -

I didn't say "hope alone", it was just a light hearted turn of phrase.
But then the only two certain things in life are "death and taxes".How's it going, AKA, Nutwatch? - 12 month spends to date = 2.60% of current retirement "pot" (as at end May 2025)3
