Mid-Month Musings

16th January 2026 by Mark Potter Leave a Comment

As I explained in my email at the end of last year, my plan for 2026 is to post a detailed Deep Dive article as previously at the start of the month and then add another post, which will be of whatever content I think might be useful to readers, in the middle of the month. As always, I can research and write a piece on request, if any reader wants me to.

In terms of word count and read time, the longer article will be about 2500 words with a 10 to 15 minute reading time required (and perhaps complex enough to require a second look over!) and the mid-month pieces about 1000 words and only 5 minutes demanded!

This month, I have been thinking about the markets which I have a less concrete or confident opinion about. I am pretty sure that it makes sense to invest less in the USA and more in Europe and the UK and I don’t see merit in spending time on the Japanese market, so that leads me to focus on the Asia Pacific ex-Japan region and on Emerging Markets, which two sectors would have quite an overlap in a Venn diagram.

Deep Dive – January 2026

5th January 2026 by Mark Potter Leave a Comment

This new year I will take a classical approach and do the look back and look forward that underlies the naming of the month.

I usually read what I wrote a year ago at the start of any new cycle but I note that I deferred offering a full opinion on the impact of Trump’s election until after his inauguration, so the blog post to reference is the one for February 2025.

My analysis of Trump’s likely behaviour was accurate in almost every detail.  My expectation that the US Dollar would lose credibility was also correct.  However, I did not foresee that AI would be far and away the main corporate story of the year and that the bubble I was worrying about 11 months ago would keep inflating.  I was right in my expectations of a poor climate for healthcare stocks and that money would flow into defence industry shares.

So how did markets perform in 2025?

DIY Investing – does it pay off?

15th December 2025 by Mark Potter Leave a Comment

Readers will have maybe noted that a great deal of the money being invested by retail investors is going into ETFs and most of those, although now a decreasing proportion, will be passive index trackers. In addition, plenty of money goes into mutual funds that are passive, and even model portfolios where the asset allocation may be varied a bit from time to time, but the underlying strategy is largely far from active and trackers are used to get market exposures.

Are we doing well?

The founder of Vanguard, which firm is now one of the largest owners of lsited investments in the world, made his name arguing that paying for portfolio management was a waste of time because the vast majority of managers in the USA failed to beat the S&P 500 index consistently. Now, we all know that is not a very complete rationale (why would the S&P 500 be your sole benchmark?, for instance) but if the index makes enough money over the long term to meet your investment objectives and it can be tracked very cheaply, why not do that? Clearly, a great many people have agreed that was the way to go!

Deep Dive – December 2025

1st December 2025 by Mark Potter Leave a Comment

Firstly, may I wish all my readers seasonal greetings, hoping that all your Christmas preparations are going well!  Most importantly, as most of us are the wrong side of pension age, I wish you the best of ongoing health!

Having written a couple of longish and quite technical pieces last month on AI and ETFs, I am going to offer a more leisurely and shorter read this month! The dive will not be so deep, more of a swim in interesting waters.

Not quite time to doze off!

A question to which the answer may not appear to matter that much – but it does!

That question is:

How To – Use Artificial Intelligence to Review a Portfolio of UK Investment Funds

17th November 2025 by Mark Potter Leave a Comment

(although in the format of a ‘How To’ article that would usually form part of the website’s permanent content, this topic is fluid and I am still learning, so I am leaving the article as an, albeit very detailed, blog post)

Introduction

Artificial intelligence (AI) has emerged as a game-changer across various sectors, and the investment management industry is no exception. Reviewing and managing a portfolio of UK investment funds can be a complex and time-consuming task.  I have offered subscribers some Excel workbooks over the years, more recently with support from one of your fellow investors who is a spreadsheet programming ace. Both he and I have wondered about adding AI elements to data collection process (the most boring part of the task) or even creating an app that both improves the data presentation and semi-automates the review process.

The App is a work in progress and I may well be able to offer you access to it (at a cost) at some future date, but in the meantime I have explored the possibility of AI completing a portfolio review and quite quickly learned that there can be good outcomes, with genuine portfolio insights, time savings in data analysis and (with care) reliable and repeatable date collection.

A caveat that all experienced AI users will not need to hear is that AI is like an over eager Jeeves – it will always try to please you with some sort of result, making its best efforts credible, even when in fact they are pure fiction.  That means that the way it is tasked to provide data requires some thought and requests must always be qualified with conditions that include reporting the exact sourcing and likely reliability of specific data.
