Largest buyer：Corporación Arditel, S.L. · 8.30m EUR
Gross qualified purchase transaction-line value：8.30m 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.

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, 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 (large purchases); short sellers, company results were checked and none crosses a bear threshold. No data is held for: share price and trading, company actions.

  • The insider purchases themselvesBulllarge purchases Bearone buyer only, latest purchase is old3 checked, under the threshold · 3 missing
  • Share price and tradingno data held
  • Short sellers1 checked, under the threshold
  • Company results1 checked, under the threshold · 1 missing
  • Company actionsno data held

Bull case · the buying is informative

  • Net purchases of €6.0M equal 0.29% of the company's market value (€2.1bn): large for the size of the business.

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%).
  • The latest purchase was 176 days ago (2026-04-24). A reporting period has passed since, so what the buyers knew then may already be public.

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 49%). Whether earnings and cash flow are rising or falling needs the last two reports side by side.
  • European notifications have no field saying whether a purchase was pre-arranged; there is no counterpart to the US 10b5-1 box. The one purchase line does not mention a plan, but a bare “Compra” 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: 5
  • Either1 insider bought in the last 180 days and 1 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.
  • BearNo insider sale is recorded in the same 180 days.
  • BearThe register of CNMV 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 49%. 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.
