Shares for the future: the 31 companies I think are good value
After a month that saw one of his stocks taken over by chocolate bar firm Mars, columnist Richard Beddard runs through some of the thinking behind his new scoring system and names the shares it says are worth owning.

It is the turn of the month, and as usual we are publishing the list of shares ranked by my Decision Engine. Each share's score is still determined by my annual evaluation of the business and daily movements in the share price.
Under the hood though, much is changing because I have started to implement a new version of the scoring system. You can read about the new methodology in last month’s Shares for the future article.

This month, I need to deal with the fallout: how to merge the new and old systems, and make sure they still help me decide how much of each share to hold.
Jury-rigging the Decision Engine
So far, I have scored three companies using the new method, so 37 of the 40 shares in the Decision Engine still have their old scores. They will be re-scored next time they publish an annual report, in up to a year or so’s time.
This gives us a headache, because we are comparing apples with oranges.
Actually, it is more like comparing two different oranges as the two scoring systems do the same thing in a similar way. I expect most shares that scored highly under the old system to do well under the new system and that is how it has worked out so far.
In a few cases, the new system may result in more radical re-evaluation, but that happens occasionally anyway.
Mixing the two systems creates technical conundrums, though.
The most obvious is that the maximum score has changed. The old system scored shares out of 9, and the new system scores shares out of 10. That really is comparing apples to oranges.
I have fixed that problem by scaling each old score up by a factor of 1.111, so now they have the same weight as scores out of 10.
Changing the maximum score raises another issue: the benchmark for deciding whether a high quality business is good value or not.
Traditionally, I have regarded shares that score 7 or more as good value, shares that score 5 or 6 as fair value and shares that score less than 5 to be poor value.
These are arbitrary benchmarks, and I intend to leave them where they are. That, though, creates another problem.
Penalising expensive shares
The scores do not just help me decide whether to hold a share, they also help me decide how much of a share to hold. The higher the score, the greater that share should be as a proportion of its total value.
To show why this might be a problem, I need to talk a bit about the price score.
Like many investors I compare price to profit, although I use enterprise value (the value of equity and debt) instead of the more common market capitalisation (the value of equity) to put a price on the business. I also normalise profit to estimate how much it might earn in a typical year.
This produces a normalised earnings yield (profit in a typical year as a percentage of the firm’s enterprise value). The earnings yield is profit divided by price, and we can translate it back to something that most investors understand using its reciprocal, price divided by profit, the price-to-earnings or PE ratio.
I use a sigmoid function to turn the earnings yield into a score. When plotted, a sigmoid function produces an ‘s’ shaped curve, with the earnings yield on one axis, and the score on the other. The table on the left of the chart shows the more common PE ratio for each earnings yield.
![rb1.png](https://media-prod.ii.co.uk/s3fs-public/2023-11/rb1.png)
Any share with a PE of less than 10 (an earnings yield of more than 10%) is rewarded with a maximum price score of 1. Between a PE of 17 and a PE 20 (an earnings yield of 5) shares get a score of around 0, and then as the PE rises and the earnings yield falls, shares are penalised by up to a maximum of three points.
This method has the illusion of being scientific, but just in case you think I am a very clever chap, I described the outcome I wanted to some mates who are good at maths, and they gave me the sigmoid function.
Under the rejigged function, shares can score a maximum of 1 and a minimum of -3. Under the old system, shares could score a maximum of 1 and a minimum of -2.
To see why a minimum price score of -2 might be a problem, consider a business of the highest quality. Under the new scoring system it would score 9 for the criteria of dependability, distinctiveness and direction, before the algorithm takes price into account.
That means, even if the share traded on a very high PE of 100, the minimum it could score would be 7 (9 minus 2), which, according to my arbitrary benchmark, is good value.
In other words, the Decision Engine would be telling me to hold a lot of that share at any price.
Since price is a factor in the returns we earn from investments, I do not think we can be so cavalier. With a minimum price score of -3, the minimum overall score for a business of the highest quality stays at 6 (9-3).
How much of a share to hold
Having recalibrated the scoring system, we can use it to determine how much of a share to hold.
The ideal holding size (ihs) is calculated by another formula, which I have also updated to reflect the new maximum score of 10. It is:
ihs = score - (10 - score)
This formula nudges me to hold only 2% of a portfolio in shares scoring 6:
Score | Ideal holding size (%) |
10 | 10 |
9 | 8 |
8 | 6 |
7 | 4 |
6 | 2 |
5 | 0 |
Living with bias
If one thing jumped out at you from my rather technical explanation, I hope it is that the Decision Engine is not scientific.
I mention this because of an email from a reader, DM, who points out that the results of the Decision Engine are influenced by my own biases.
That, I think, is inevitable, unless we adopt a purely quantitative approach to investing.
Rather than eliminating bias, I am trying to shape and contain it. I am reinforcing good biases, like the focus on quality and value, and reducing potentially harmful biases, principally rushes of blood to the head!
31 shares for the future
I re-score each share in the Decision Engine once a year, after the publication of the annual report.
Since the last update a month ago, Thorpe (F W) (LSE:TFW), PZ Cussons (LSE:PZC) and Renishaw (LSE:RSW) have been through the process. To see how I scored them, please click on the share’s name in the table below.
James Halstead (LSE:JHD), Softcat (LSE:SCT) and YouGov (LSE:YOU) have all published annual reports and are due to be updated.
Generally, I consider shares that score 7 or more out of 10 to be good value. This month there are 31. Shares that score 5 or 6 out of 10 are probably fairly priced.
Sometimes things happen in between reviews that may change a share’s score, but I do not re-score a share until the company publishes its next annual report. This protects me from knee-jerk decisions, ensures I have as much information as possible, and keeps me focused on evaluating one firm at a time.

XP Power Ltd (LSE:XPP) and Quartix Technologies (LSE:QTX) fall into this category due to self-inflicted financial difficulties at the power adapter manufacturer, and boardroom changes at the vehicle tracking firm that make me wonder about its strategic direction.
Last month, I suggested I might remove Hotel Chocolat Group (LSE:HOTC) from the Decision Engine and replace it with another idea. That will happen because Mars has made my mind up for me. The giant food conglomerate is taking Hotel Chocolat over.
Despite misgivings about the long-term potential of the share, I am sorry to see Hotel Chocolat lose its independence. It is a distinctive business, and they are in quite short supply.
