WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+17.1 / 35
How many distinct insiders bought in the cluster
Purchase size+17.8 / 25
Purchase value relative to company size and liquidity
Role+13.0 / 20
The seniority and relevance of participating insiders
Recency+8.7 / 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
- ✓ Recent activity · latest purchase 2026-10-21
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
1 purchase day(s), 1 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.
Insider timeline
One insider bought, once (21 Oct). The share closed at 35.90 that day and at 35.90 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, +7.8% over these six months
The closing price of each day, from 33.30 on 2026-04-27 to 35.90 on 2026-10-21. 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, −1.5%
Taken from the 120 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 +7.8%, the typical one −1.5%, 9.3 points ahead. 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
Independent evidence does not object: the purchases themselves carry bull lines (bought in the last two weeks); share price and trading, company results were checked and none crosses a bear threshold. No data is held for: short sellers, company actions.
- The insider purchases themselvesBullbought in the last two weeks3 checked, under the threshold · 3 missing
- Share price and tradingBearthinly traded2 checked, under the threshold
- Short sellers1 missing
- Company results1 checked, under the threshold · 1 missing
- Company actionsno data held
Bull case · the buying is informative
- The latest purchase is 2 days old (2026-10-21). The buying is current, not left over from an earlier quarter.
Bear case · discount it
- Share price and tradingAbout €67k 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
- This register does not name the filer, so the 1 purchase line may come from one person or from several. Breadth of buying cannot be judged.
- Only one reading of profitability is held (profit margin 3.3%). Whether earnings and cash flow are rising or falling needs the last two reports side by side.
- This company's market publishes no register of net short positions (it is outside the EU Short Selling Regulation), so whether professional investors are positioned against the buying cannot be read from a public source.
- 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” 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: 6, 1 close to it
- EitherInsider purchases in the last 20 sessions equal 4.3% of the stock's traded value. Bull from 5.0%, bear below 0.50%. close to the threshold
- EitherNet purchases equal 0.03% of the company's market value. Bull from 0.10%, bear below 0.01%.

Why did it change?

These are underlying national-feed records from the 365-day window ending on the saved ranking snapshot. The score uses only the latest 180 days; older qualifying equity purchases remain visible for audit but do not enter the current score. The original filer, role, transaction classification, instrument, price, volume, value and source fields are retained. The first three rows are shown; remaining records can be unfolded for audit. Other transaction types are retained but excluded from the score.
