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 2026-11-03, neither column has changed. 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 (senior executive buying, bought in the last two weeks); share price and trading, short sellers, company results were checked and none crosses a bear threshold.
- The insider purchases themselvesBullsenior executive buying, bought in the last two weeks Bearone buyer only, associated persons buying, usual level for this company, buyer's past purchases trailed the benchmark2 missing
- Share price and trading2 checked, under the threshold
- 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
- 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 8,812 earlier disclosures like this, the median 60-session excess return was −3.1%, within 1 percentage point of all comparable disclosures (−3.4%).
- The latest purchase is 7 days old (2026-10-29). The buying is current, not left over from an earlier quarter.
Bear case · discount it
- Company actions2 of 2 purchase lines are subscriptions 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.
- Only one insider bought. A single purchase can reflect that person's own finances rather than a view on the company.Record: after 4,900 earlier disclosures like this, the median 60-session excess return was −3.0%, within 1 percentage point of all comparable disclosures (−3.4%).
- 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 1,680 earlier disclosures like this, the median 60-session excess return was −8.0%, 2.1 percentage points below all comparable disclosures (−5.9%).
- Buying at this level is normal here: 3 insiders bought in the previous 180 days and 1 in this one.Record: after 2,827 earlier disclosures like this, the median 60-session excess return was −2.7%, within 1 percentage point of all comparable disclosures (−2.7%).
- The 8 earlier purchases by Mats Persson trailed OMX Stockholm 30 by a median 22% over the following 60 trading days.
Evidence still missing
- The recorded purchase value is under €1,000, which usually means a price or unit was not captured from the source. Check the amounts against the filing before weighing size.
- 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: 4
- BearThe share price changed −11% over six months (three months −10%, one month −0.29%) and stands 41% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed −10% and the median of 635 Industrials companies changed −2.1%: behind by 8 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.
- BearProfit margin on the latest captured figures is <0.01%. Counted for the bear side when negative.
Both columns arrange stored facts only. They do not change the insider score or the ranking and are not investment advice.

WHY THIS SIGNAL?
Score anatomy
Each bar is that part's points in the score; the five parts add up to the score.
Number of buyers+10.5 / 35
How many different insiders bought within 15 days
Amount bought+10.9 / 25
The value bought, net of any insider sales
Buyers' roles+0.0 / 20
Lower in the company scores higher: in the backtest, purchases by the most senior insiders did worse
How recent+6.2 / 10
How long ago the latest purchase took place
Buying against selling+10.0 / 10
Lower when insiders also sold
What is holding the score back?
- ⚠ Few buyers · fewer than 4 different insiders
- ⚠ The amount bought is small on the score's scale
- ⚠ Buyers' roles add little · most senior buyer: CEO / chair; the most senior score lowest
- ⚠ The latest purchase was some time ago
Buyers' roles follow the European ranking's order of roles: the most senior insiders score lowest.
Buying concentration
100%
Largest buyer：Mats Persson · 31k SEK
Purchases counted, before sales：31k SEK
The amount at the top of the page is purchases minus sales; this one counts purchases only, in the filing currency, so the two can differ. The score counts how many people bought; this shows separately who bought the most.
This is a ranking under the current European screening rules—not a probability of gain, return forecast, or buy recommendation.

Insider timeline
One insider bought, once (29 Oct). The share closed at 2.32 that day and at 2.35 most recently (+1.3%).
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, −5.2% over these six months
The closing price of each day, from 2.48 on 2026-05-11 to 2.35 on 2026-11-04. 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, −6.5%
Taken from the 738 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 −5.2%, the typical one −6.5%, 1.3 points ahead. It is not an index and not a comparison within one industry.

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 06 Nov 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.
