Abstract

fetched live from OpenAlex

Syftet med studien är att undersöka om det finns något signifikant samband mellan den verkställande direktören och företagets prestation efter börsnotering. Författarna hoppas studien kan bidra med ny kunskap och inspirera för framtida studier på området. Datan består av 777 företags noteringar på de nordiska handelsmarknaderna Nasdaq Stockholm, Nasdaq Copenhagen, Nasdaq Helsinki, Oslo Børs, First North och Oslo Axess. All aktiekursdata är på daglig basis och insamling av data har skett via databaserna: Zephyr, Datastream, Bloomberg och Finansinspektionen. Företagsspecifik information har inhämtats via prospekt och företagens årsredovisningar. Studien uppvisade att två av de valda variablerna hade signifikant positiv påverkan på företagets långsiktiga prestation. Företag som bytt VD efter börsnotering påvisade att prestationen signifikant skiljde sig från företag med samma VD. Någon signifikant skillnad i prestation mellan branscher gick inte att påvisa. För urvalet presterade företagen signifikant bättre än valt jämförelseindex.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
