Yet after 19 years there is no evidence of the manifestation of this theoretical risk, and in that time we had the biggest financial crisis since 1929.
On the contrary, there is such evidence from those 19 years of HYP1, in the following forms:
* The maximum concentration of capital in any single HYP1 company has risen from 6.7% originally to 16.3% now.
* The maximum concentration of income generation in any single HYP1 company has risen from about 9.5% originally (based on the forecast yields in
https://web.archive.org/web/20140528041 ... 01113c.htm) to 24.1% now.
* HYP1 had quite a bit of concentration risk in pyad's
November 2007 review, with BT being 11.8% of its capital value and providing 19.3% of its income. His
November 2010 review (*) shows that that risk actually manifested in the financial crisis over the following three years, with the income from the holding falling by £466 - which is the largest contribution to HYP1's income drop over those three years, despite three companies cancelling their dividends entirely. In fact, no other company was producing as much as £466 income in 2007, so none of them even
could have contributed that much to the fall!
So there is evidence of the risk being there at present, and of it having manifested in the past. There isn't evidence of it currently manifesting (which I suspect may be what you mean), but the idea of dismissing it until and unless there is such evidence strikes me as about as good as the idea of leaving the stable door unbolted until the horse is halfway out and bolting at full speed! The
risk is currently there - one just needs to look at the percentages in single companies to see that - and if it needs acting on, it's better acted on
before it materialises. Note though that I'm neither saying that it does need acting on nor that it doesn't - because that's a decision each HYPer needs to make for themselves about their own HYP, in the light of their own circumstances (e.g. how dependent are they on their HYP's income?) and preferences (especially how risk-averse they are).
(*) I would like to have used his November 2008 and November 2009 reviews as well, but AFAIAA he never produced a November 2008 review, and his
November 2009 review didn't give an income breakdown by company. There was a
November 2008 breakdown produced by kool4kats, who also produced one for 2009 a couple of replies into the first of those links, but that's not "from the horse's mouth" and it was for a somewhat different portfolio (the one later known as CHYP1). For what it's worth, I'm reasonably certain those breakdowns' BT dividend figures are correct, since
this and
this (a couple of TMF posts) confirm that the BT share count is correct - but the portfolio totals are not.
