WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
How many distinct insiders bought in the cluster
Purchase value relative to company size and liquidity
The seniority and relevance of participating insiders
How recently the purchases occurred
How clearly buying stands out from other activity
What is holding the score back?
- ⚠ Buyer breadth is moderate · fewer than 4 distinct filers
- ⚠ Insider role contributes less on the current role scale
- ⚠ Purchase activity is becoming less recent
The role contribution uses the inverted role input of the current European model.
Buying concentration
Largest buyer:Raju Capital Oy · 52k EUR
Gross qualified purchase transaction-line value:52k EUR
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
1 purchase day(s), 14 purchase line(s) in the 180-day window. 2 sale day(s), 21 sale line(s).
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 |
|---|---|---|---|---|
| 2026-08-26 | 1 | 917 −8.3% | 957 −4.3% | −40 −4.0 pts |
0 of 1 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 (21 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, once (25 Aug). The share closed at 8.76 that day and at 7.98 most recently (−8.9%).
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.
Blue line: this share's price, −19.2% over these six months
The closing price of each day, from 9.88 on 2026-04-21 to 7.98 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, −1.0%
Taken from the 54 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 −19.2%, the typical one −1.0%, 18.2 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.
This company: insiders buying per month, last 12 months
Darker bars are inside the 180-day window above.

Purchases against sales
Shares of the reported value of insider transactions in the 180-day window. 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.
Why this score? · Model details
Priority = 100 × Σ(fixed weight × 0–1 rule-based input)

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 bear side: thinly traded. All bull and bear lists, and what followed each line in the past →
Where the evidence comes from
- The insider purchases themselvesBearplan, dividend or pay wording, one buyer only, insiders also sold4 checked, under the threshold · 2 missing
- Share price and trading2 checked, under the threshold
- Short sellers1 checked, under the threshold
- Company results2 missing
- Company actionsno data held
Bull case · the buying is informative
Every purchase line here follows a plan, a dividend or pay terms, so nothing held supports reading the buying as a decision.
Bear case · discount it
- 14 of 14 purchase lines are worded as a managed account or standing order, for example “ACQUISITION (X) Executed under portfolio or asset management”. Purchases of that kind follow a schedule or an entitlement, not a decision made now.
- 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%).
- Insiders also sold €18k in the same 180 days, 35% of the amount bought.
Evidence still missing
- No buyer here has 5 or more completed earlier purchases on record, so there is no track record to weigh.
- 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.
- 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
- BearThe share price changed −18% over six months (three months −6.8%, one month −5.5%) and stands 20% below its 52-week high. Counted for the bear side from a fall of 20%. close to the threshold
- Either1 insider bought in the last 180 days and 0 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 1 buyer filed as a person closely associated with a manager. Counted for the bear side from half.
- EitherNet purchases of €34k in 180 days. Bull from €1.0M, bear when all purchases total under €25k.
- EitherThe latest purchase is 53 days old. Bull up to 14 days, bear from 90.
- BearOver three months the share price changed −6.8% and the median of 176 Basic Materials companies changed +<0.01%: behind by 7 points. Counted for the bear side from 20 points behind.
- BearThe register of Finanssivalvonta 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 Helsinki 25 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 cap is the share count implied by the report's profit and earnings per share (the year's average), multiplied by the latest close; shares issued or bought back since are not counted. It does not affect the insider score or rank.
Disclosed net short positions
The Finanssivalvonta 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.
