WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+10.5 / 35
How many distinct insiders bought in the cluster
Purchase size+21.8 / 25
Purchase value relative to company size and liquidity
Role+19.0 / 20
The seniority and relevance of participating insiders
Recency+3.1 / 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
- ⚠ Purchase activity is becoming less recent
- ✓ Strong insider role · assoc involved
The role contribution uses the inverted role input of the current European model.
Buying concentration
100%
Largest buyer：Adam Ian Lundin · 1.79m CAD
Gross qualified purchase transaction-line value：1.79m CAD
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.

Insider vs stock price
3 purchase day(s), 3 purchase line(s) in the 180-day window.
Daily close (USD)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 |
|---|---|---|---|---|
| 2026-07-02 | 1 | 773 −22.7% | too few peers | — |
| 2026-09-01 | 1 | 774 −22.6% | too few peers | — |
| 2026-10-02 | 1 | 870 −13.0% | 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 (30 Sep). The share closed at 0.12 that day and at 0.09 most recently (−18.5%).
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, −51.1% over these six months
The closing price of each day, from 0.19 on 2026-04-21 to 0.09 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.

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: no longer on the bull side: bought in the last two weeks. 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 (buyer's past purchases beat the benchmark); short sellers were checked and none crosses a bear threshold. No data is held for: share price and trading, company results, company actions.
- The insider purchases themselvesBullbuyer's past purchases beat the benchmark Bearone buyer only, associated persons buying, usual level for this company3 checked, under the threshold · 2 missing
- Share price and tradingno data held
- Short sellers1 checked, under the threshold
- Company results2 missing
- Company actionsno data held
Bull case · the buying is informative
- The 7 earlier purchases by Adam Ian Lundin beat OMX Stockholm 30 by a median 10% over the following 60 trading days.
Bear case · discount it
- Only one insider bought. A single purchase can reflect that person's own finances rather than a view on the company.Record: after 4,732 earlier disclosures like this, the median 60-session excess return was −2.7%, within 1 percentage point of all comparable disclosures (−3.3%).
- Every buyer is filed as a person closely associated with a manager (family or a holding vehicle), not the manager. This model weights such filers among the least informative.Record: after 1,554 earlier disclosures like this, the median 60-session excess return was −7.4%, 1.6 percentage points below all comparable disclosures (−5.8%).
- Buying at this level is normal here: 8 insiders bought in the previous 180 days and 1 in this one.Record: after 2,869 earlier disclosures like this, the median 60-session excess return was −2.6%, within 1 percentage point of all comparable disclosures (−2.7%).
Evidence still missing
- The company's market value is not captured, so the purchases cannot be stated as a share of the business or of its trading volume.
- No earnings, margin or cash-flow figures are captured for this company. The latest annual and interim reports are where to check whether the business is improving or deteriorating.
- 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 “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: 4, 1 close to it
- EitherThe latest purchase is 17 days old. Bull up to 14 days, bear from 90. close to the threshold
- EitherNet purchases of €676k in 180 days. Bull from €1.0M, bear when all purchases total under €25k.
- BearNo insider sale is recorded in the same 180 days.
- 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.
Both columns arrange stored facts only. They do not change the insider score or the ranking and are not investment advice.

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.

Market context
No price, valuation or fundamentals have been captured for this stock yet.
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.
