The reasons why out of all the shares I bought this one

Share Sleuth’s intention is to hold the shares for at least a decade. Here’s his newest acquisition.

Although interactive investor has published the Share Sleuth portfolio for many years, it has always waited for Money Observer magazine to publish it first.

One of the delights of reading the magazine was the clatter of the letterbox, the opening of the biodegradable packaging, and the appreciation of the work of many contributors packaged tightly within. 

The penalty was the time it took to produce the package, which means the Share Sleuth update was always a few weeks old by the time readers performed our monthly ritual.

Money Observer has closed and from now on Share Sleuth will be published directly on interactive investor and bang up to date - as long as you remember to come and read it in the first week of the month.

Share Sleuth has always had a second home at interactive investor. Most of my research is published here, and this research informs the trades in the model portfolio. 

Happily I can demonstrate, because I traded in July. 

New addition: D4t4

On 27 July, I added 1,528 shares in D4t4 (LSE:D4T4) to the Share Sleuth portfolio at a share price of 229p, the actual share price quoted by a broker. The total cost of the transaction was £3,509 including £10 in lieu of broker fees. D4t4 is a company that sells software that captures data about our behaviour as we use websites. 

As usual, I only committed 2.5% of the portfolio’s total value, which was about £140,000 on the day. Trading in relatively small amounts gives me scope to add more shares in future as I get to know D4t4 better, or indeed back out relatively gracefully. Backing out is not my intention though. My intention is to hold the shares for a decade at least.

Following the trade, Share Sleuth has about £2,000 in cash, which can only be augmented by dividends and sales. Dividends are hard to come by during the pandemic and in July the portfolio received them from just two companies, Judges Scientific (LSE:JDG) and Anpario (LSE:ANP)

Since the level of cash is well below 2.5% of the value of the portfolio, my trade size, it is highly likely the next trade will reduce a holding or remove it entirely from the portfolio. 

The portfolio now has 27 members, high by past standards, although I have never had the courage to reduce it to below 20. 

Why D4t4, out of all the shares available?

When we invest in a company, we are choosing it above all the others available to us, which is essentially an act of comparison. This is how I chose D4t4:

First, I scored the company, measuring it up against the same five criteria I measure all shares: profitability, risk, strategy, fairness and value. 

Then I shuffled D4t4 into the pack, all the shares I follow closely enough to score,  and sorted it so I could see how it compared to all of the others I follow. Companies with the highest scores are, in my mind, probably the best long-term investments.

Stage three follows the scoring and the sorting. It is, of course, the trade, which you are reading about today.

On 27 July, D4t4 was the third most attractive share but the two higher ranked shares (Dewhurst (LSE:DWHT)and Victrex (LSE:VCT)) were not available to the Share Sleuth portfolio. Both are stalwarts already worth about 5% of the portfolio’s total value. 

According to the formula that tells me how much to invest in each company I could invest more in these shares, but not as much as 2.5% of the portfolio’s value, my trade size. Any trade smaller than this would not have much impact. It would be frittering away at the edges of the portfolio.

The maths is relatively straightforward and coded into a spreadsheet. 

Dewhurst, the highest ranked share, has a score of 9 (out of 10). I use the score to determine the ideal size of a holding as a percentage of the total value of the portfolio. The ideal size as a percentage is 75% of the score, so 6.75% in the case of Dewhurst (9*0.75).

The higher the score, the bigger the holding. 6.75% of £140,000, the portfolio’s value on 27 July when I chose D4t4 over Dewhurst, is £9,450, greater than the value of Share Sleuth’s Dewhurst holding (£6,500) but the difference, £2,950, is less than my trade size, £3,500, so I did not add more shares. 

Dewhurst’s share price would not have to fall much for it to become available to me, but it is not currently in the "buy zone".

I would not normally trade a share when it exceeds its ideal size either, unless it exceeds it by more than the minimum 2.5% trade size. That means holdings can grow to a maximum of 10% of the portfolio’s value in the unlikely event they score 10/10. 

That is the ideal size (7.5%) plus the trade size (2.5%).

Occasionally I let them grow even bigger, but not much.
