  1. 1. Påverkar free float prisjusteringen på ex-dagen?

    Kandidat-uppsats, Uppsala universitet/Företagsekonomiska institutionen

    Författare :Filip Fajerson; Olof Burman; [2023]
    Nyckelord :Ex-dagseffekt; Free float; Utdelning; Prisfallskvot; Stockholmsbörsen;

    Sammanfattning : Ex-dag är benämningen på dagen när en aktie inte längre handlas med rätt till utdelning. Följaktligen justeras aktiepriset nedåt som en konsekvens av att rätten till utdelning försvinner. Enligt den effektiva marknadshypotesen (Fama, 1970) borde storleken på prisjusteringen och utdelningen återspegla varandra. LÄS MER

  3. 2. Solar Photovoltaic Fire Risks : FE-analysis of fire exposed solar photovoltaic systems and comparison of current legislation and recommendations from different countries
