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+22.5 / 25
Purchase value relative to company size and liquidity
Role+20.0 / 20
The seniority and relevance of participating insiders
Recency+1.2 / 10
How recently the purchases occurred
Conviction+9.7 / 10
How clearly buying stands out from other activity
What is holding the score back?
- ⚠ Buyer breadth is moderate · fewer than 4 distinct filers
- ⚠ Purchase activity is becoming less recent
- ✓ Strong insider role · ceo/chair involved
The role contribution uses the inverted role input of the current European model.
Buying concentration
Not worked out: the scoring window holds no qualifying purchase filing, or the purchases are reported in more than one currency.
This is a ranking under the current European screening rules—not a probability of gain, return forecast, or buy recommendation.

Daily close (SEK)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 |
|---|---|---|---|---|

6 of 6 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 (278 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 2 days, 28 May to 29 May: 2 Board member. 4 more bought afterwards. The share closed at 53.35 on the first of those days and at 54.45 most recently (+2.1%). That week 237 companies across Europe disclosed insider purchases, more than in 81% of the last 26 weeks: insiders often buy together when a closed period ends, so the timing alone says less than it seems.
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 May – 29 May, 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, −4.0% over these six months
The closing price of each day, from 56.70 on 2026-04-21 to 54.45 on 2026-10-09. 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, −9.2%
Taken from the 457 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 −4.0%, the typical one −9.2%, 5.2 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: 237 companies, number 4 of the last 26 weeks. If that week was a peak anyway, buying together is less special than it looks.

Purchases against sales
Purchases86%6 line(s) · 6 insider(s)
Sales14%1 line(s) · 1 insider(s)
Shares of the NUMBER of transactions in the 180-day window: a reported value is missing for 0 line(s), or the lines are in more than one currency, so values cannot be added up. Sales include disposals for tax, at option exercise or under a pre-set plan, which say little about an insider's view. The split describes what was disclosed; it is not a signal.

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; no longer on the bear side: small purchases. 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 (more buyers than usual here, senior executive buying), while short sellers argue against (published short positions); company results argue against (loss-making). No data is held for: company actions.

- Company actionsno data held
Bull case · the buying is informative
- 6 insiders bought in the last 180 days against 3 in the 180 days before: more than this company's own recent norm.Record: after 3,134 earlier disclosures like this, the median 60-session excess return was −2.7%, within 1 percentage point of all comparable disclosures (−2.7%).
- The buyers include the CEO or chair, who sees more of the business than most filers. This site's score gives little or no credit for that: in its backtests purchases by senior executives did no better than other insiders' purchases.Record: after 8,797 earlier disclosures like this, the median 60-session excess return was −3.1%, within 1 percentage point of all comparable disclosures (−3.2%).
Bear case · discount it
- Company resultsThe company is loss-making on the latest captured figures: profit margin −2.2%, return on equity −4.3%.
- Short sellersDisclosed net short positions total 10.99% of the share capital across 13 named holders: other professional investors are positioned the opposite way. On 2026-10-02 it was 10.19%: up 0.80 points since.
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 −2.2%). Whether earnings and cash flow are rising or falling needs the last two reports side by side.
- 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 6 purchase lines mentions a plan, but a bare “Förvärv” 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
- BullAt most 2 insiders bought within any 15 days. Counted for the bull side from 3. close to the threshold
- Bear0 of 6 buyers filed as a person closely associated with a manager. Counted for the bear side from half.
- EitherNet purchases equal 0.05% of the company's market value. Bull from 0.10%, bear below 0.01%.
- BearInsiders sold €29k in the same 180 days, 2.7% of the amount bought. Counted for the bear side from 25%.
- EitherThe latest purchase is 30 days old. Bull up to 14 days, bear from 90.
- BearThe share price changed −1.6% over six months (three months +15%, one month +9.0%) and stands 18% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed +15% and the median of 271 Healthcare companies changed −6.3%: ahead by 21 points. Counted for the bear side from 20 points behind.

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 − OMX Stockholm 30 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.
