Share Sleuth: here’s how the portfolio could change in 2022

Richard Beddard is considering cutting the portfolio’s number of holdings. Here, he reveals the 19 shares that would win a place if each had its ideal allocation.
Psst! Do you want a glimpse of the future? Would you like to see what the Share Sleuth portfolio might look like in January 2023?
I may be in a position to oblige, because I am thinking about reducing the number of holdings it contains.

On diversification and decisiveness
In 2009, when I made the portfolio’s first investments, Share Sleuth was called the Thrifty 30, Thrifty because it was invested in good companies at reasonable prices, and 30 because the intention was to hold about 30 shares.
It changed names early on for a technical reason. I also ran a portfolio called the Nifty Thrifty, and we decided the names were too similar. Since 2009 though, the Thrifty 30/Share Sleuth portfolio has comprised nearly 30 constituents. Today it has 28.

It will take courage to reduce that number for two reasons. The first is perhaps the obvious one. The more shares we own, the lower the impact on our returns should one of them fail.
It works the other way too, of course. A holding that does extraordinarily well will have a huge positive impact, if it is one of only a few.
Reducing our potential gains by owning more shares will never be catastrophic, though, while the risk of failure from owning too few could be. Diversification is an insurance policy, and it is probably best to err a little on the safe side.
The second reason that reducing the number of holdings will take courage is it requires me to be more decisive, which does not come easily.
This is why the number and size of holdings in the Share Sleuth portfolio differs from what they would be if I to follow the recommendations of my Decision Engine more closely.
Calculating the ideal size of a holding
The Decision Engine is a ranked list of shares I have researched and scored in the last year. It guides me towards better decisions and gives me a bit more of a spine. Behind the scenes, it also calculates how much of each holding I should own based on its “ideal holding size”.
A share scoring a perfect 9 out of 9 has an ideal holding size of 10% of the total value of the portfolio, while a share scoring 5 out of 9, has an ideal holding size of 2% (where s is a share’s score, the ideal holding size as a percentage of the portfolio’s total value is s+1-(9-s)).
If I were to rebalance the Share Sleuth portfolio so every share had its ideal allocation, it would only contain 19 holdings. They are in the following table along with the actual Share Sleuth (SS) allocations:
The Ideal portfolio
Company | Score | Ideal | SS |
8 | 8% | 4% | |
8 | 8% | 4% | |
8 | 8% | 2% | |
8 | 7% | 4% | |
8 | 7% | 6% | |
7 | 7% | 6% | |
7 | 7% | 6% | |
7 | 7% | 3% | |
7 | 6% | ||
7 | 6% | 5% | |
7 | 5% | 4% | |
7 | 5% | 2% | |
7 | 5% | 6% | |
6 | 5% | 5% | |
6 | 5% | 2% | |
6 | 5% | 4% | |
99% | 61% |
Every share is under-represented in the Share Sleuth portfolio except for Solid State and FW Thorpe.
If I were to follow my research to its logical conclusion, I should increase the holdings that are well below their ideal sizes but I cannot, because the money is already accounted for by lower-ranked holdings, shares that score less:
The rest of Share Sleuth
Company | Score | Ideal | SS |
6 | 5% | 7% | |
6 | 4% | 3% | |
6 | 4% | 3% | |
6 | 4% | 3% | |
6 | 4% | 1% | |
6 | 4% | 2% | |
6 | 4% | ||
6 | 4% | 3% | |
6 | 4% | 2% | |

5 | 2% | 2% | |
5 | 2% | ||
5 | 2% | ||
5 | 1% | 2% | |
n/a | 37% |
In this table, the ideal holding sizes are not relevant as we have already allocated 100% of the portfolio to the higher ranked shares. While I would invest in these businesses were there not higher scoring ones available, because there are, their ideal size is effectively 0%.
A total of 37% of the Share Sleuth portfolio is invested in these shares, which makes me think there is room for improvement.
There are good reasons for the divergence between the holding sizes of some of the shares in the Ideal portfolio and the Share Sleuth portfolio. PZ Cussons, James Latham and D4T4 are all significantly underrepresented but they are also relatively new holdings and I tend to build holdings up to their ideal sizes in stages.

I am less confident than I would like to be in my analysis of Portmeirion, which is not in the Share Sleuth portfolio, and news that two of Cohort’s subsidiaries are underperforming means I am beginning to question the company’s acquisitive strategy. Until I next review the scores of these shares, I am holding off on trading them.
But there are also holdings in the Ideal portfolio that I would happily add to now, Dewhurst, Goodwin and Quartix, for example, and I hope to find new companies to invest in too.
To add to the portfolio’s higher scoring holdings or make new investments, I will need funds, which barring dividends can only come from reducing or removing lower scoring holdings.
My goal for 2022, therefore, is to dispose of some of the 37% of the portfolio that is less than ideal in order to take the ideal part of the portfolio beyond 61%.
If that happens, by January 2023, Share Sleuth might look a bit more like the ideal portfolio in the table above, and a bit less like the portfolio of January 2022 below.
Share Sleuth performance
On Wednesday 5 January, the Share Sleuth portfolio was worth £212,395, which is 608% more than the notional £30,000 invested in the portfolio’s first year, from September 2009.
Past performance is not a guide to future performance.
The same amount invested in accumulation units of a FTSE All-Share index tracking fund would have appreciated to £75,118 over the same period.
The portfolio’s cash balance has swelled to £4,043 thanks to dividends from Bunzl, Games Workshop and Tristel.
The cash balance is not insufficient to fund new additions at my minimum trade size of 2.5% of the portfolio’s total value (about £5,300).
