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+15.3 / 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：Bruce Hiscock · 11k GBP
Gross qualified purchase transaction-line value：11k 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
2 purchase day(s), 2 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 |
|---|---|---|---|---|
| 2026-04-28 | 1 | 1,061 +6.1% | 1,030 +3.0% | +30 +3.0 pts |
| 2026-06-24 | 1 | 1,000 +0.0% | 1,000 +0.0% | 0 +0.0 pts |
1 of 2 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 (351 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, 2 times, the latest (24 Jun). The share closed at 1,750.00 that day and at 1,750.00 most recently (+0.0%).
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, +2.9% over these six months
The closing price of each day, from 1,700.00 on 2026-04-27 to 1,750.00 on 2026-10-08. 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, +2.9%
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 +2.9%, the typical one +2.9%, 0.0 points ahead. It is not an index and not a comparison within one industry.

This is a heuristic ordering under the current rules, not a calibrated return forecast. It explains why candidates rank differently; the public-filing evidence and data limits are shown below.
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
Independent evidence does not object: the purchases themselves carry bull lines (senior executive buying); share price and trading, short sellers, company results, company actions were checked and none crosses a bear threshold.
- The insider purchases themselvesBullsenior executive buying Bearone buyer only, latest purchase is old, usual level for this company, buyer's past purchases trailed the benchmark3 checked, under the threshold · 2 missing
- Share price and trading2 checked, under the threshold
- Short sellers1 checked, under the threshold
- Company results1 checked, under the threshold · 1 missing
- 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 121 days ago (2026-06-24). A reporting period has passed since, so what the buyers knew then may already be public.
- Buying at this level is normal here: 4 insiders bought in the previous 180 days and 1 in this one.Record: after 2,808 earlier disclosures like this, the median 60-session excess return was −2.9%, within 1 percentage point of all comparable disclosures (−2.7%).
- The 9 earlier purchases by Bruce Hiscock trailed FTSE 100 by a median 18% over the following 60 trading days.
Evidence still missing
- Only one reading of profitability is held (profit margin 59%). 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. None of the 2 purchase lines mentions 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, 1 close to it
- EitherNet purchases equal 0.01% of the company's market value. Bull from 0.10%, bear below 0.01%. close to the threshold
- Bear0 of 1 buyer filed as a person closely associated with a manager. Counted for the bear side from half.
- BearNo insider sale is recorded in the same 180 days.
- BearThe share price changed −5.4% over six months (three months +11%, one month +8.0%) and stands 30% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed +11% and the median of 302 Healthcare companies changed −5.8%: ahead by 17 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.
- BearProfit margin on the latest captured figures is 59%. Counted for the bear side when negative.

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.
