I've extricated myself from the arduous task of sunning myself in the garden in order to answer Bob's questions!
I'm a bit confused by what you wrote here.
I reckoned that the Duke's "clients" have relatively small pension pots and so couldn't incur the overhead associated with asking a stockbroker to set up an ARF for them. It is a long time since my ARF was set up, I don't recall the precise costs, but I doubt very much if it would be worth the associated overhead for a smaller pension pot.
My comment on the validity of the concept irrespective of size of pot was saying that, if fixed overheads were not a concern, the approach I've been adopting for the last 7 1/2 years with my ARF (and for the previous dozen or so years during the accumulation stage) will be equally applicable for smaller pension funds.
can you also explain whether you are advocating a very small number of shares - again for normal people?
I recognise that I am an outlier in terms of my approach to concentration risk, and I would not necessarily recommend a similar approach by others. I was simply telling what I have done. I started off 20 years or so ago by following a conventional approach, with a portfolio of 20 or 30 stocks. I eventually recognised that I just bought many of the stocks on a whim and decided to focus my attention on companies that I could be reasonably confident about, having researched them. I'm not a full-time investor, so have limited time for research. This obviously limits the number of stocks in the portfolio. The relative performance of my portfolio has improved significantly since then.
As an aside, I think much the same is true of professional portfolio managers. I recall reading a report somewhere that the good performance of high performing portfolios is concentrated in about five or six stocks, and that the rest are basically fillers. I also recall attending an investment conference a few years ago at which the manager of a particular portfolio said that stocks the managers classified as "winners" accounted for 20% of the portfolio. He didn't have a satisfactory answer when I asked why "winning" stocks it didn't account for 100% of the portfolio.
Comparing my approach to investing with that of the amateur investors who have decided to eschew the rarefied world of insurance companies, investment advisers, et cetera in favour of doing their own thing by buying a few houses or apartments for investment purposes, they would be more than happy with a portfolio of eight apartments, rented out to different customer types in different cities across the world. That's how I look at the portfolio of a small number of different companies’ shares in my ARF. The biggest investments are in companies that I am confident will stand the test of time: they have sound balance sheets; projected dividends and profits are such that I expect to get a good return even if I never decide to sell; they are unlikely to be driven out of business by Amazon, Facebook, or whoever.
I’m not pushed if I don’t beat the index; all I want is the risk-free rate plus 4% to 6% in the long-term. I’m happy that my portfolio will deliver that long-term return. I invest smaller amounts in shares that I think will deliver, but which I’m not yet certain about. In time, as I get more familiar with the company, I may decide to increase my holding.
can you also explain why there is no need to be concerned "sequence of returns" risk?
“Sequence of returns” risk is only a cause for concern if it is necessary to sell stocks when they’re down. Obviously, falls in market values concern me as much as they do anyone else, but I have a very low turnover rate on my portfolio and, as I indicated in my previous post, I don't ever recall having had to sell a stock in order to meet the "income" requirement (because of dividend receipts, cash balances in the portfolio, etc.). Back to my earlier analogy of an amateur investor who has a portfolio of apartments, I just throw the notes from the estate agents into the bin if I don't like the prices they are offering for the apartments at any particular time.
And how realistically could a "normal" person no good stocks to pick when professional managers have a hard time beating benchmark returns in the long haul?
As I said earlier, I have no particular desire to beat benchmarks; all I want is to earn a real return of 4% to 6% per annum. Experience over many years has shown that an average portfolio would have achieved that objective. As it happens, my long-term track record compares well with that of professional managers but I recognise that most of my long-term success can be attributed to one company that I was lucky to discover 20 years ago and which I have stuck with since then.
