WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+17.4 / 35
How many distinct insiders bought in the cluster
Purchase size+22.6 / 25
Purchase value relative to company size and liquidity
Role+13.0 / 20
The seniority and relevance of participating insiders
Recency+3.3 / 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
- ⚠ Insider role contributes less on the current role scale
- ⚠ Purchase activity is becoming less recent
The role contribution uses the inverted role input of the current European model.
Buying concentration
The filings do not name the buyer, so who bought how much cannot be worked out.
This is a ranking under the current European screening rules—not a probability of gain, return forecast, or buy recommendation.

Insider vs stock price
11 purchase day(s), 11 purchase line(s) in the 180-day window.
Daily close (CHF)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.

6 of 11 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 (91 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, 11 times, the latest (1 Oct). The share closed at 143.00 that day and at 143.50 most recently (+0.3%).
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, −10.6% over these six months
The closing price of each day, from 160.50 on 2026-04-21 to 143.50 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, −0.6%
Taken from the 89 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 −10.6%, the typical one −0.6%, 10.0 points behind. 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.
