Price vs insider buying
MIG.AT · EUR● Purchase × Sale ◇ Public disclosure ▥ 15-day cluster ·
Circles and crosses mark trade dates; diamonds below the axis mark later public disclosures. The trade became public on its disclosure date. Prices are nearest-session closes, not insider execution prices. Marker sizes are not compared when values or currencies differ.
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

- Short sellers1 missing
- Company results1 checked, under the threshold · 1 missing
- Company actionsno data held
Bull case · the buying is informative
Nothing held here goes beyond the fact that an insider bought.
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 4,900 earlier disclosures like this, the median 60-session excess return was −3.0%, within 1 percentage point of all comparable disclosures (−3.4%).
- Share price and tradingAbout €33k 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
- No buyer here has 5 or more completed earlier purchases on record, so there is no track record to weigh.
- Only one reading of profitability is held (profit margin 32%). Whether earnings and cash flow are rising or falling needs the last two reports side by side.
- The short-position register for this company's market is not captured here, so whether professional investors are positioned against the buying is not known.
- 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 2 purchase lines mentions a plan, but a bare “Acquisition” 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: 9
- 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 equal 0.01% of the company's market value. Bull from 0.10%, bear below 0.01%.
- EitherInsider purchases in the last 20 sessions equal 2.0% of the stock's traded value. Bull from 5.0%, bear below 0.50%.
- BearNo insider sale is recorded in the same 180 days.
- EitherThe latest purchase is 24 days old. Bull up to 14 days, bear from 90.
- BearThe share price changed −6.6% over six months (three months −14%, one month −3.0%). Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed −14% and the median of 229 Real Estate companies changed −5.5%: behind by 8 points. Counted for the bear side from 20 points behind.
- BearProfit margin on the latest captured figures is 32%. Counted for the bear side when negative.

How many different insiders bought within 15 days
Amount bought+15.4 / 25
The value bought, net of any insider sales
Buyers' roles+3.0 / 20

Buying against selling+10.0 / 10
Lower when insiders also sold
What is holding the score back?
- ⚠ Few buyers · fewer than 4 different insiders
- ⚠ Buyers' roles add little · most senior buyer: ?; 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：Georgios Efstratiadis · 13k EUR
Purchases counted, before sales：13k EUR
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.

●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, −6.4% over these six months
The closing price of each day, from 3.28 on 2026-05-11 to 3.07 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.

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 − Athens General Composite 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.

Filing evidence
These are underlying national-feed records from the 365-day window ending on the saved ranking snapshot. The score uses only the latest 180 days; older qualifying equity purchases remain visible for audit but do not enter the current score. The original filer, role, transaction classification, instrument, price, volume, value and source fields are retained. The first three rows are shown; remaining records can be unfolded for audit. Other transaction types are retained but excluded from the score.
