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+17.9 / 25
Purchase value relative to company size and liquidity
Role+13.0 / 20
The seniority and relevance of participating insiders
Recency+5.4 / 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
3 purchase day(s), 3 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.
| Made public | Insiders | In this stock, now | In the median peer stock, now | Difference |
|---|---|---|---|---|
| 2026-08-11 | 1 | 651 −34.9% | too few peers | — |
| 2026-08-12 | 1 | 651 −34.9% | too few peers | — |
| 2026-10-08 | 1 | 1,137 +13.7% | 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
One insider bought, 3 times, the latest (8 Oct). The share closed at 7.21 that day and at 8.20 most recently (+13.7%).
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, −54.1% over these six months
The closing price of each day, from 17.87 on 2026-04-21 to 8.20 on 2026-10-16. 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, +0.0%
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 −54.1%, the typical one +0.0%, 54.1 points behind. 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.
Since 2026-10-13: new on the bear side: loss-making. All bull and bear lists, and what followed each line in the past →
Where the evidence comes from
The two kinds of evidence disagree: the purchases themselves carry bull lines (bought in the last two weeks), while share price and trading argue against (price down over six months, price trails its sector); company results argue against (loss-making). No data is held for: short sellers, company actions.

Bull case · the buying is informative
- The latest purchase is 9 days old (2026-10-08). The buying is current, not left over from an earlier quarter.
Bear case · discount it
- Company resultsThe company is loss-making on the latest captured figures: profit margin −284%.
- Share price and tradingThe share price is down 54% over six months (three months −33%, one month −29%). Insiders have bought into a fall the market has not reversed.Record (nearest stored case: price 20% or more below its prior 52-week high): after 11,077 earlier disclosures like this, the median 60-session excess return was −3.2%, within 1 percentage point of all comparable disclosures (−2.6%).
- Share price and tradingOver three months the share price changed −33% and the median of 271 Healthcare companies changed −6.3%: 27 points behind. The market has marked this company down against its own sector.
Evidence still missing
- This register does not name the filer, so the 3 purchase lines may come from one person or from several. Breadth of buying cannot be judged.
- Only one reading of profitability is held (profit margin −284%). 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. None of the 3 purchase lines mentions 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: 2
- EitherNet purchases equal 0.03% of the company's market value. Bull from 0.10%, bear below 0.01%.
