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+21.4 / 25
Purchase value relative to company size and liquidity
Role+20.0 / 20
The seniority and relevance of participating insiders
Recency+7.6 / 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
- ✓ Strong insider role · ceo/chair involved
- ✓ Recent activity · latest purchase 2026-10-13
The role contribution uses the inverted role input of the current European model.
Buying concentration
59%
Largest buyer：Fredrik Crafoord · 5.56m SEK
Gross qualified purchase transaction-line value：9.47m 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.

Insider vs stock price
5 purchase day(s), 9 purchase line(s) in the 180-day window.
Daily close (EUR)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 |
|---|---|---|---|---|
| 2026-05-25 | 1 | 277 −72.3% | too few peers | — |
| 2026-08-26 | 1 | 619 −38.1% | too few peers | — |
| 2026-08-27 | 1 | 578 −42.2% | too few peers | — |
| 2026-09-08 | 1 | 667 −33.3% | 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
2 insiders bought within 14 days, 25 Aug to 7 Sep: 1 CEO / chair, 1 Board member. 1 of them bought again later. The share closed at 0.01 on the first of those days and at 0.01 most recently (−39.5%). That week 182 companies across Europe disclosed insider purchases, an ordinary week (14 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 25 Aug – 7 Sep, 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, −67.1% over these six months
The closing price of each day, from 0.02 on 2026-04-21 to 0.01 on 2026-10-14. 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, −2.0%
Taken from the 37 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 −67.1%, the typical one −2.0%, 65.1 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: 182 companies, number 14 of the last 26 weeks. If that week was a peak anyway, buying together is less special than it looks.

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: large purchases, bought in the last two weeks. 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 (large purchases, senior executive buying, bought in the last two weeks), while share price and trading argue against (price down over six months, price trails its sector).
- The insider purchases themselvesBulllarge purchases, senior executive buying, bought in the last two weeks Bearbuyer's past purchases trailed the benchmark5 checked, under the threshold · 1 missing
- Share price and tradingBearprice down over six months, price trails its sector
- Short sellers1 checked, under the threshold
- Company results1 checked, under the threshold · 1 missing
- Company actionsBearsubscription to new shares
Bull case · the buying is informative
- Net purchases of €535k equal 8.7% of the company's market value (€6.2M): 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 4 days old (2026-10-13). The buying is current, not left over from an earlier quarter.
Bear case · discount it
- Company actions1 of 9 purchase lines is a subscription to newly issued shares (“Teckning”), bought from the company at an issue price and not in the market. Insiders often take part to support a financing.
- Share price and tradingThe share price is down 65% over six months (three months −59%, one month −10%) and stands 77% 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%).
- Share price and tradingOver three months the share price changed −59% and the median of 66 Energy companies changed +10%: 70 points behind. The market has marked this company down against its own sector.
- The 6 earlier purchases by Fredrik Crafoord trailed OMX Stockholm 30 by a median 9.8% over the following 60 trading days.
Evidence still missing
- Only one reading of profitability is held (profit margin <0.01%). Whether earnings and cash flow are rising or falling needs the last two reports side by side.
- 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, 2 close to it
- BullAt most 2 insiders bought within any 15 days. Counted for the bull side from 3. close to the threshold
- Bear1 of 3 buyers filed as a person closely associated with a manager. Counted for the bear side from half. close to the threshold
- Either3 insiders bought in the last 180 days and 2 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.
- BearThe largest buyer accounts for 59% of the value bought. Counted for the bear side from 80%.
- 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.
- BearProfit margin on the latest captured figures is <0.01%. Counted for the bear side when negative.

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.
