WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+10.5 / 35
How many distinct insiders bought in the cluster
Purchase size+13.7 / 25
Purchase value relative to company size and liquidity
Role+18.0 / 20
The seniority and relevance of participating insiders
Recency+0.0 / 10
How recently the purchases occurred
Conviction+10.0 / 10
How clearly buying stands out from other activity
What is holding the score back?
- ⚠ Buyer breadth is moderate · fewer than 4 distinct filers
- ⚠ Purchase activity is becoming less recent
- ✓ Strong insider role · cfo involved
The role contribution uses the inverted role input of the current European model.
Buying concentration
100%
Largest buyer：Kris Grimwood · 4k GBP
Gross qualified purchase transaction-line value：4k GBP
The headline € total is net buying for the screen; this module uses gross qualified purchase transaction-line values in the filing currency, so the amounts can differ. The current 15-day buyer-breadth input counts distinct buyers; value concentration is disclosed separately here.
This is a ranking under the current European screening rules—not a probability of gain, return forecast, or buy recommendation.

Insider vs stock price
1 purchase day(s), 1 purchase line(s) in the 180-day window.
Daily close (GBp)Day with an insider purchase
Markers sit on the closing price of the transaction day. They show when insiders traded, not the price they paid or received. "Since" compares that day's close with the last close shown; it is what happened at this company, not a forecast.
If you had followed the purchase
Each row starts on the first close on or after the day a purchase was made public, the earliest a reader could have acted, and ends on the last close shown above.
| Made public | Insiders | In this stock, now | In the median peer stock, now | Difference |
|---|---|---|---|---|
| 2026-05-15 | 1 | 907 −9.3% | 1,026 +2.6% | −118 −11.8 pts |
0 of 1 disclosure day(s) ended ahead of the median peer stock.
Close to close, before costs, taxes, dividends and currency moves. The peer is the median of the other stocks on the same exchange for which this site holds prices (80 here), not an index. This is what happened, not a forecast: across all purchases on this site the typical gap is close to zero.
Insider timeline
One insider bought, once (15 May). The share closed at 27.00 that day and at 24.50 most recently (−9.3%).
Tap an item for what it means.
●A purchase: the bigger the dot, the more was bought
Each dot is one insider's purchases on one day. The dot's area follows the amount: the largest purchase here gets the largest dot. Hold the pointer over a dot to see the date and the amount.
Blue line: this share's price, −9.3% over these six months
The closing price of each day, from 27.00 on 2026-04-27 to 24.50 on 2026-10-22. The line has no scale; read it for high and low: a dot on a low stretch was bought cheaply, a dot on a high stretch was not.
Dashed line: the typical stock on the same exchange, +4.3%
Taken from the 610 other stocks on the same exchange that this site holds prices for. Each is measured from the first day of the window, and every day the middle one is drawn. It starts where the blue line starts, so the gap between the two is the difference: this share −9.3%, the typical one +4.3%, 13.5 points behind. It is not an index and not a comparison within one industry.

BULL VS BEAR
Two readings of this buying
The same filings, read two ways. Each line is a fact stored for this company with the number behind it, and appears only when that number crosses a fixed threshold. Neither side is a forecast and no winner is declared.
All bull and bear lists, and what followed each line in the past →
Where the evidence comes from
The two kinds of evidence disagree: the purchases themselves carry bull lines (senior executive buying), while company results argue against (loss-making).
- The insider purchases themselvesBullsenior executive buying Bearone buyer only, latest purchase is old4 checked, under the threshold · 3 missing
- Share price and tradingBearthinly traded2 checked, under the threshold

- Company actions1 checked, under the threshold
Bull case · the buying is informative
- The buyers include the CFO, who sees more of the business than most filers. This site's score gives little or no credit for that: in its backtests purchases by senior executives did no better than other insiders' purchases.Record: after 8,738 earlier disclosures like this, the median 60-session excess return was −3.1%, within 1 percentage point of all comparable disclosures (−3.2%).
Bear case · discount it
- Only one insider bought. A single purchase can reflect that person's own finances rather than a view on the company.Record: after 4,757 earlier disclosures like this, the median 60-session excess return was −2.8%, within 1 percentage point of all comparable disclosures (−3.3%).
- The latest purchase was 161 days ago (2026-05-15). A reporting period has passed since, so what the buyers knew then may already be public.
- Company resultsThe company is loss-making on the latest captured figures: profit margin −5.4%, return on equity −19%.
- Share price and tradingAbout €726 of the stock changes hands on an average day, below this site's €500k screening line. A position is hard to enter or leave at the quoted price.
Evidence still missing
- No buyer here has 5 or more completed earlier purchases on record, so there is no track record to weigh.
- Only one reading of profitability is held (profit margin −5.4%). Whether earnings and cash flow are rising or falling needs the last two reports side by side.
- European notifications have no field saying whether a purchase was pre-arranged; there is no counterpart to the US 10b5-1 box. The one purchase line does not mention a plan, but a bare “Purchase of Ordinary Shares” does not rule one out.
- The filings give the size of each trade, not what the buyer already held. Whether a purchase added 1% to a personal stake or doubled it is not known.
Checked and under the threshold: 8
- Either1 insider bought in the last 180 days and 0 in the 180 days before. Bull when the number at least doubles and rises by two; bear when at least two bought before and no more buy now.
- Bear0 of 1 buyer filed as a person closely associated with a manager. Counted for the bear side from half.
- EitherNet purchases equal 0.06% of the company's market value. Bull from 0.10%, bear below 0.01%.
- BearNo insider sale is recorded in the same 180 days.
- BearThe share price changed −9.3% over six months (three months +8.9%, one month −2.0%) and stands 32% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed +8.9% and the median of 355 Technology companies changed −1.9%: ahead by 11 points. Counted for the bear side from 20 points behind.
- BearThe register of FCA shows no published net short position in this company.
- BullThe company announced no transaction in its own shares in the last 30 days.

Insider profile outcomes
Historical performance following insider filings. The company role is translated below each name while preserving the original title.
- Excess return = stock return − FTSE 100 return over the same period.
- Hit rate = completed events with positive excess return ÷ total completed events.
- Price coverage = valid point-in-time prices ÷ events mature enough for that period.
- Returns start on the first shared trading session on or after publication.
- Small-sample rule: n<5 is shown for transparency and is not scored.
Events are disclosure-level observations; related disclosures published on the same date may share a return path and may not be statistically independent. This research enrichment does not affect the insider score or ranking.
