(not so) Deep Dive – July 2026

1st July 2026 by Mark Potter Leave a Comment

Readers have, I can safely assume, just lived through some very hot weather and I am writing this sat directly in the air conditioner ouput in my flat. I have today seen the fairly dire meteriological predictions that result from computer modelling of El Nino. Also on this very day, I also saw independent media content explaining that the US administration is shutting down it most authorative climate monitoring services, on the authority of that narcissistic dim-witted leader who is too busy looking to plunder more wealth for himself and his family to care about his fellow humans, never mind the planet and all future generations.

Bad news – shut down the newsroom!

I am not proposing that we accept without question that global warming is a man-made event without question, merely observing instead that it would very probably be useful to have the best possible data available to scientists who might work out some solutions to what is obviously more of a problem than just discomfort.

I have kicked off with this observation because I intend to explore the question of how the world now deals with inconvenient truths, focusing on aspects that are relevant to investment markets. Maybe we are approaching the ‘last times’ of a very long investment market cycle, where only an ‘Armaggedon’ will clean up the many sins of the markets and allow a fresh start?

It occurs to me that eschatology may not be what some readers are looking for from this web site. Although I firmly believe, as you will know, that markets and ultimately the valuation of our investments are the distillation of human behaviours, not the pseudo science of economics, so feel justified in taking a tangential look at what seem to be absurdities in current marjet patterns, I can offer an alternative for those not interested who still want to do some useful reading to brush up their portfolio maintenance skills.

YAP – a change of climate?

24th June 2026 by Mark Potter Leave a Comment

I detect a significant trend emerging in global equity markets. Enough participants are now doubting the ludicrous pricing of AI related stocks and the technology sector of the US equity market, as seen in the NASDAQ 100, had become highly volatile and I think is showing signs of becoming bearish.

Mid-month Musings – June 2026

15th June 2026 by Mark Potter Leave a Comment

I had decided a while back to use this publication slot to offer some illustrative numbers to support my often stated opinion that for most investors ‘buy and hold’ is not, on its own, the most advanatageous of options, even though I have no doubt at all that attempting to ‘time the market’ is a very unwise strategy. My proposition has been for a long time that staying in the market with the right assets, well diversified, is always going to make you richer in the long run, but you can enhance your returns and reduce your risk by taking profits when valuations look stretched, and then topping up your investments after a correction is obviously set in and the bad news is well and truly ‘in the price’.

Here we are considering the systemic risks and the trend in whole equity market valautions (although I use a focused equity market to make the point), not the relative value of different assets in the portfolio mix, although the principles adapt well to trading in and out of asset classes of all sorts, not just equities and cash.

Some numbers
for you

Is this a relevant issue worth your time?

This is one approach of contrarian investing and I have seen the merits of it for decades, although that is not to say that I am evangelical about the style – it is just a technique worth knowing about and using if you want to be just a little more advanced as an investor. Not adopting the methodology I propose will not damage portfolios that are well desingned to start with over the longer term, any more than driving a gas guzzler car will stop you reaching your destination in comfort: it is just that my suggested trading style improves efficiency and gives you more miles per gallon, or maybe Pounds per month.

I should mention that data which follows will not be easy to read on a phone and I recommend viewing on a large tablet or screen.

A Riddle

7th June 2026 by Mark Potter Leave a Comment

Q: What do you get if take a pee and see, then put in an n and a k?

A: if you start with SPACE, you get SNAKE.

The IPO of Space X is one of the most blatant corruptions of the regulations and institutions supposedly there to protect the public, a set of maneuvres akin to the trickery of the snake oil salesman. That is not my sole opinion, but one of many independent professional commentators and publishers.

Deep Dive – June 2026

1st June 2026 by Mark Potter Leave a Comment

‘To infinity, and beyond!’

Reportedly a comment from the Pixar Animation Studios equivalent of Warren Buffet, Buzz Lightyear, speculating yesterday on the Nasdaq composite index!

Well, no actually, although he has been known to utter those words, I don’t think a Toy Story animated spaceman will ever be seen as offering an alternative to the Wall Street Journal. Even though the film script writers are probably just as capable as the financial journalists when it comes to guessing next week’s stockmarket valuation.

The quotation is certainly appropriate to the staggering and in my opinion completely irrational performance of the US stock markets over the last few weeks, more or less starting one month after the invasion of Iran. Readers will know that this is mainly driven by all sorts of stocks loosely connected to the booming investment in AI infrastructure. That is not the same as saying it relates to booming profits or even actual profits growth for AI companies.

Not Harry
Up, up and away!

I have already set out some evidence as to why the underlying fundamentals suggest that this growth in equity valuation cannot be sustained (May’s Deep Dive), and some of those facts have even got worse since I wrote about them. So why is this all happening?
