WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+35.0 / 35
How many distinct insiders bought in the cluster
Purchase size+17.6 / 25
Purchase value relative to company size and liquidity
Role+17.1 / 20
The seniority and relevance of participating insiders
Recency+3.3 / 10
How recently the purchases occurred
Conviction+6.9 / 10
How clearly buying stands out from other activity
What is holding the score back?
- ⚠ Purchase activity is becoming less recent
- ⚠ Buying conviction is reduced by concurrent selling
- ✓ Broad buyer cluster · 4+ distinct filers
- ✓ Strong insider role · ? involved
The role contribution uses the inverted role input of the current European model.
Buying concentration
12%
Largest buyer：ANDREA ROSSI · 20k EUR
Gross qualified purchase transaction-line value：160k EUR
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.

1 purchase day(s), 8 purchase line(s) in the 180-day window. 1 sale day(s), 1 sale line(s).
Daily close (EUR)Day with an insider purchaseTwo or more insiders the same dayDay 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 |
|---|---|---|---|---|
| 2026-10-02 | 8 | 1,013 +1.3% | too few peers | — |
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 (0 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
8 insiders bought on the same day, 1 Oct: 8 Role not classified. The share closed at 84.50 that day and at 85.40 most recently (+1.1%). That week 183 companies across Europe disclosed insider purchases, an ordinary week (13 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 1 Oct, with 8 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, +13.9% over these six months
The closing price of each day, from 75.00 on 2026-04-21 to 85.40 on 2026-10-14. 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, −5.6%
Taken from the 26 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 +13.9%, the typical one −5.6%, 19.5 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: 183 companies, number 13 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: no longer on the bull side: bought in the last two weeks. 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 (several insiders together); share price and trading, company results were checked and none crosses a bear threshold. No data is held for: short sellers, company actions.

- Company results1 checked, under the threshold · 1 missing
- Company actions1 missing
Bull case · the buying is informative
- 8 insiders bought on the same day (2026-10-01). Several people reaching the same decision at the same time is hard to put down to one person's circumstances.Record: after 5,401 earlier disclosures like this, the median 60-session excess return was −3.3%, within 1 percentage point of all comparable disclosures (−3.3%).
Bear case · discount it
- Insiders also sold €43k in the same 180 days, 44% of the amount bought.
- Net purchases of €53k are <0.01% of the company's market value (€1.4bn): 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.
- Only one reading of profitability is held (profit margin 20%). Whether earnings and cash flow are rising or falling needs the last two reports side by side.
- The short-position register for this company's market is not captured here, so whether professional investors are positioned against the buying is not known.
- The next scheduled results are on 2026-11-12. They are the first hard test of either reading.
- 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 8 purchase lines mentions a plan, but a bare “ACQUISTO” 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: 7, 1 close to it
- EitherThe latest purchase is 16 days old. Bull up to 14 days, bear from 90. close to the threshold
- BearThe largest buyer accounts for 12% of the value bought. Counted for the bear side from 80%.
- Bear0 of 8 buyers filed as a person closely associated with a manager. Counted for the bear side from half.
- BearThe share price changed +16% over six months (three months −2.0%, one month +6.0%) and stands 17% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed −2.0% and the median of 462 Industrials companies changed −0.32%: behind by 2 points. Counted for the bear side from 20 points behind.
- BearProfit margin on the latest captured figures is 20%. Counted for the bear side when negative.
- BearAbout €639k of the stock changes hands on an average day. Counted for the bear side below €500k.

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 MIB 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.
