Comment and opinion for retail investors in the UK

Deep Dive – May 2026

29th April 2026 by Mark Potter Leave a Comment

In this article, published slightly early as the facts change so quickly that it might be stale in a few days, I want to follow up on my April mid-month post comment stating that I believe that whatever behavioural factors are driving stock market valuations, in the end fundamental factors will serve to restore prices to levels that make sense in an investment world where owning one sort of asset is always at the opportunity cost of owning another with different risk and return characteristics.  In other words, an overvalued asset class will always eventually be sold off to buy into a cheaper one – we just don’t know when that will happen.

What I thought might be useful would be to list out some of the fundamental data that suggest that equity markets have become detached from reality.  You can make a judgment as to what, taken all together, this information implies for the immediate future and whether or not those implications would prompt action on your part to defend or enhance your personal wealth.

Mid-month Musings – April 2026

14th April 2026 by Mark Potter Leave a Comment

Optimism or baked in behaviour?

Readers will have no doubt noticed, probably with relief, that however absurd the latest Truth Social post from Trump is, however counter-productive US policy is, however belligerent Israeli and Iranian leaders remain, whatever the direction of the oil price or data on tanker movements, stock markets have and are taking everything swimmingly. 

Perhaps that seems strange to you?  You would not be alone.

The conventional wisdom

Most experienced stock market investors would tell you that what happens in the global economy is useful in assessing the long term direction of asset valuations but really has no direct impact on short term share price movements unless that news indicates a systemic or all-encompassing change in the climate for business.

The shorter term valuation of shares should logically depend upon current company profitability, or at least expected future earnings, in the case of equities, and the trend in interest rates when it comes to fixed income stocks.

This might be the logic that should be applied currently. The markets are assuming that the war will be short lived and although oil prices have shot up with all the implications we are familiar with, this is taken as short term only and will not impact corporate profitability and perhaps only slightly delay the previous trend of reducing interest rates.

Deep Dive – April 2026

31st March 2026 by Mark Potter Leave a Comment

(published early as I am having a minor operation on April 1st)

Totally Reckless Uncontrolled Malign President (TRUMP)

I have written earlier this year that the main geopolitical risks were Trump, Trump and Trump and the conduct of the Israeli/ American war with Iran has been such as to make even the most experienced independent ‘talking head’ whether a political, diplomatic or military commentator admit that they cannot detect any strategic plan, understand the USA’s actual objectives or even believe that what the President writes on Truth Social even amounts to the policy of anyone other than the man himself at that very moment in whatever mental state he happens to be and with whatever most recent influences have fed his brain.

This is a state of affairs that seems almost beyond belief but I think that some news organisations either have not grasped the reality, or feel that that they should not risk suggesting anything is other than normal and that the US Secretary of State really travels the world with a real idea of what US policy on conducting the war will be tomorrow morning. I imagine that he actually finds out what policy he is supposed to defend by reading Truth Social when he wakes up.

I could write many thousands of words telling you what I think is really happening and why, but that is not the purpose of this blog.  Investors are interested in the likely consequences of this state of affairs in terms of asset values in the near term and also beyond that.   Here are my observations on that topic. I do have to touch a little on the actual events but will do my best to stick to facts as opposed to opinions about what will happen next in the Middle East.

Mid-Month Musings – extra content

18th March 2026 by Mark Potter Leave a Comment

Blinded by the Light

When the climax of the firework display is filling the sky with colours and explosions that are impossible to absorb as anything more than a momentary impression, a burglar walking into the house across the road, torch focused in a narrow beam, has an excellent chance of not being noticed.

Keep your eyes wide open

The tendency of humans to focus on ‘big’ events or things that our instincts react to as threatening or in other ways stimulating to our bio-chemistry is well understood by those whose job is to manipulate the flow of public information. 

Many a press officer will have timed a data release that must be made but which is unhelpful to their principal at exactly the time when some other major news event is grabbing the headlines.  I am sure such specialists scour the weather forecasts waiting for a pending typhoon or flood so as to know when to issue that necessary but unfortunate press release saying that the department has spent several hundred million on a project that yielded no tangible economic or social benefit!

I want to look at this general tendency from the point of view of an investor who, being well educated and responsible, likes to keep up to date with world events with a view to anticipating risks and minimizing unexpected losses of portfolio value. 

Now is a good time to think about the possibility that important news relevant to investors may be going ‘under the radar’, simply because the Trump/Netanyahu war of choice in the Middle East is so scarily, albeit quite logically, taking over the vast majority of news coverage and analysis.

Mid Month Musings – First Casualty

13th March 2026 by Mark Potter Leave a Comment

Preface (written March 13th)

Most of what follows was written a few days ago.  In the interim, a whole range of news filtered into the mainstream, often covering elements that I had until then thought were being ignored by the main UK media. Perhaps the issue is delay, maybe because of a responsible desire for verification.  It is certainly noticeable that The Sun will run a story that is sensational must earlier than say the Daily Telegraph or the Guardian and Sky News will run a more likely propaganda report before the BBC.

The part of the text below over which I dithered the most was the first speech by the Iranian leader.  I had heard this from a questionable (based on its likely geo-political angle) source but it seemed credible.  In fact, while holding the article for final edit, I was only pondering whether to cut it, ot add a stronger caveat.  Yesterday the speech was officially published, probably not made by the man himself, who is almost certainly in hospital, but I would assess as having his approval. It was nearly exactly the same as the version I had heard, which multiple AI checks had vehemently denied existed!

Thinking time

The fact that with only an internet connection and an aging brain, I can research and to a degree forecast what is happening in the world is not a surprise to me, because that is how I have earned a living over recent years and sustained my own modest finances, with the odd ‘cock-up’of course!.  What is as surprise is that the people charged with making decisions that impact millions of lives, terminating thousands in fact, either cannot see the consequences of their decisions, or more likely suffer such psychological impairments that they ignore the appropriate advice of those both paid and well able to know what is going to happen.

I offer what follows under the general aegis of pointing out that the USA’s decision (in compliance with Israel) to start a war with Iran is the stupidest political act I have observed in my life and the potential consequences are being severely underestimated by stock markets. 

It MAY not be so bad, but my methodology has for years been about assessing probabilities, and at this time not only is the degree of risk very high, but the likely damage might be at a level we have not seen since the dot.com crash – which had an impact lasting 3 years. If I am wrong, nobody will be upset, I think.

Given the rate at which things are changing and the known flip-flopping of POTUS, I will add update my publsihed opinions more often than usual if necessary in my judgement. In the meantime, I think that what I wrote a few days back still stands up. Here is the article:

Deep Dive – March 26 – Iran War Edition

4th March 2026 by Mark Potter Leave a Comment

This article will as promised attempt to assess some probable consequences for investors of the US and Israeli attacks on Iran.

Looking for a precedent

Given that I was a teenager, just into working life, when the Yom Kippur War of late 1973 kicked off, it is no surprise that it is firmly printed in my memory.  I specifically recall buying petrol for my 50cc moped with a ration book!  That time period has plenty in common with what might be developing now, although it must immediately be noted that there have been some distinct structural changes in the global economy over the more than half century that has elapsed, more of which later.

As a starting point let’s take advantage of AI to get a summary of what happened then.  Here is text from MS CoPilot, lightly edited by me.
