Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+29.8 / 35
How many distinct insiders bought in the cluster
Purchase size+25.0 / 25
Purchase value relative to company size and liquidity
Role+20.0 / 20
The seniority and relevance of participating insiders
Recency+9.3 / 10
How recently the purchases occurred
Conviction+10.0 / 10
How clearly buying stands out from other activity
What is holding the score back?
- ✓ Broad buyer cluster · 4+ distinct filers
- ✓ Strong insider role · ceo/chair involved
- ✓ Recent activity · latest purchase 2026-10-16
The role contribution uses the inverted role input of the current European model.
Buying concentration
99%
Largest buyer：yaron zaltsman · 77.27m SEK
Gross qualified purchase transaction-line value：77.86m SEK
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.

6 purchase day(s), 7 purchase line(s) in the 180-day window.
Daily close (SEK)Day with an insider purchaseTwo or more insiders the same day
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 |
|---|---|---|---|---|
| 2026-07-16 | 2 | 996 −0.4% | 994 −0.6% | +2 +0.2 pts |
| 2026-07-17 | 1 | 981 −1.9% | 994 −0.6% | −13 −1.3 pts |

2 of 4 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 (33 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
3 insiders bought within 2 days, 16 Jul to 17 Jul: 1 CFO, 1 CEO / chair, 1 Board member. 2 more bought afterwards. The share closed at 1.29 on the first of those days and at 1.28 most recently (−0.4%). That week 181 companies across Europe disclosed insider purchases, an ordinary week (15 of the last 26).
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.
▮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 16 Jul – 17 Jul, with 3 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, −19.9% over these six months
The closing price of each day, from 1.61 on 2026-04-21 to 1.28 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, −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 −19.9%, the typical one −9.2%, 10.7 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. The purple bar is the week of the band above: 181 companies, number 15 of the last 26 weeks. If that week was a peak anyway, buying together is less special than it looks.

This is a heuristic ordering under the current rules, not a calibrated return forecast. It explains why candidates rank differently; the public-filing evidence and data limits are shown below.
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 bull side: bought in the last two weeks; new on the bear side: loss-making, thinly traded. 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 (several insiders together, large purchases, senior executive buying, bought in the last two weeks), while share price and trading argue against (price down over six months); company results argue against (loss-making). No data is held for: company actions.

Bull case · the buying is informative
- 3 insiders bought within 15 days (2026-07-16 to 2026-07-17). 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%).
- Net purchases of €7.0M equal 9.1% of the company's market value (€76.9M): large for the size of the business.
- 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%).
- The latest purchase is 1 day old (2026-10-16). The buying is current, not left over from an earlier quarter.
Bear case · discount it
- yaron zaltsman accounts for 99% of the value bought. The other 4 buyers add names more than money.Record: after 3,396 earlier disclosures like this, the median 60-session excess return was −3.4%, within 1 percentage point of all comparable disclosures (−3.5%).
- Company resultsThe company is loss-making on the latest captured figures: profit margin −4.7%, return on equity −0.97%.
- Share price and tradingThe share price is down 24% over six months (three months −1.9%, one month −2.3%) and stands 33% below its 52-week high. 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%).
- The 10 earlier purchases by Leiv Synnes trailed OMX Stockholm 30 by a median 8.7% over the following 60 trading days.
- Share price and tradingAbout €8,198 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
- Only one reading of profitability is held (profit margin −4.7%). 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 7 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: 5
- Either5 insiders bought in the last 180 days and 3 in the 180 days before. Bull when the number at least doubles and rises by two; bear when at least two bought before and no more buy now.
- Bear0 of 5 buyers filed as a person closely associated with a manager. Counted for the bear side from half.
- BearNo insider sale is recorded in the same 180 days.
- BearOver three months the share price changed −1.9% and the median of 164 Real Estate companies changed −6.9%: ahead by 5 points. Counted for the bear side from 20 points behind.
- BearThe register of Finansinspektionen shows no published net short position in this company. Positions under 0.5% are never published, so this does not show that nobody is short.

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.

Disclosed net short positions
The Finansinspektionen register, read 18 Oct 2026, publishes no net short position of 0.5% or more in this issuer. Positions below 0.5% are never published, so this is not evidence that nobody is short.
Short-position disclosures are external context; they do not affect the insider score, ranking, or filing eligibility.
