WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+21.0 / 35
How many distinct insiders bought in the cluster
Purchase size+16.8 / 25
Purchase value relative to company size and liquidity
Role+13.0 / 20
The seniority and relevance of participating insiders
Recency+0.7 / 10
How recently the purchases occurred
Conviction+6.1 / 10
How clearly buying stands out from other activity
What is holding the score back?
- ⚠ Buyer breadth is moderate · fewer than 4 distinct filers
- ⚠ Insider role contributes less on the current role scale
- ⚠ Purchase activity is becoming less recent
- ⚠ Buying conviction is reduced by concurrent selling
The role contribution uses the inverted role input of the current European model.
Buying concentration
72%
Largest buyer：Sonya Rogerson · 52k GBP
Gross qualified purchase transaction-line value：72k 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.

Daily close (GBp)Day with an insider purchaseDay with an insider sale
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 |
|---|---|---|---|---|
| 2026-09-01 | 1 | 998 −0.2% | 975 −2.5% | +23 +2.3 pts |
| 2026-09-10 | 1 | 1,008 +0.8% | 996 −0.4% | +12 +1.2 pts |
2 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 (454 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
2 insiders bought within 13 days, 28 Aug to 9 Sep: 2 Board member. The share closed at 503.32 on the first of those days and at 499.00 most recently (−0.9%). That week 182 companies across Europe disclosed insider purchases, an ordinary week (14 of the last 26). 1 of the buyers also disclosed a sale in the window.
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.
×A sale
A cross is one insider's sales on one day. People sell to pay tax, to cash in share awards or to hold less of one company, so a sale says less than a purchase does. When someone bought and sold on the same day, the cross sits beside the dot. The totals are under “Purchases against sales” below.
▮Purple band: several insiders bought within 15 days
The band marks the stretch with the most different buyers: at most 15 days long and at least two people. Here it is 28 Aug – 9 Sep, with 2 insiders. Only the strongest stretch is marked. Several people deciding the same thing is harder to explain by one person's private reasons, but insiders often buy together just after a closed period ends, so compare it with the grey weekly bars.
Blue line: this share's price, +12.0% over these six months
The closing price of each day, from 445.50 on 2026-04-21 to 499.00 on 2026-10-07. 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, +2.3%
Taken from the 491 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 +12.0%, the typical one +2.3%, 9.7 points ahead. It is not an index and not a comparison within one industry.
▂Grey bars: companies across Europe disclosing purchases each week
A taller bar is a week in which more companies disclosed insider purchases. The purple bar is the week of the band above: 182 companies, number 14 of the last 26 weeks. If that week was a peak anyway, buying together is less special than it looks.

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.
Since 2026-10-13, neither column has changed. All bull and bear lists, and what followed each line in the past →
Where the evidence comes from
- The insider purchases themselvesBearinsiders also sold, small purchases5 checked, under the threshold · 3 missing
- Share price and trading2 checked, under the threshold
- Short sellers1 checked, under the threshold
- Company results1 missing
- Company actions1 checked, under the threshold
Bull case · the buying is informative
Nothing held here goes beyond the fact that an insider bought.
Bear case · discount it
- Insiders also sold €54k in the same 180 days, 63% of the amount bought.
- Net purchases of €31k are <0.01% of the company's market value (€1.2bn): a visible sum, a small one against the business.
Evidence still missing
- No buyer here has 5 or more completed earlier purchases on record, so there is no track record to weigh.
- No earnings, margin or cash-flow figures are captured for this company. The latest annual and interim reports are where to check whether the business is improving or deteriorating.
- 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 4 purchase lines mentions a plan, but a bare “Purchase of 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: 9, 2 close to it
- BullAt most 2 insiders bought within any 15 days. Counted for the bull side from 3. close to the threshold
- BearThe largest buyer accounts for 72% of the value bought. Counted for the bear side from 80%. close to the threshold
- Either2 insiders bought in the last 180 days and 1 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 2 buyers filed as a person closely associated with a manager. Counted for the bear side from half.
- EitherThe latest purchase is 38 days old. Bull up to 14 days, bear from 90.
- BearThe share price changed +22% over six months (three months +4.0%, one month +2.2%) and stands 2.3% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed +4.0% and the median of 159 Closed-End Funds companies changed +1.0%: ahead by 3 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 10 transactions in its own shares in the last 30 days (latest 2026-10-14); the 6 read are all purchases. For a closed-end fund a buyback is routine: it is how the board narrows the discount to net asset value. Not counted for the bull side.

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.
