Koronaviruspandemialla on erityisen suuri vaikutus maailmantalouteen, mik\u00e4 on heijastunut osakemarkkinoihin globaalilla tasolla. Korona-ajan osakemarkkinoita k\u00e4sittelev\u00e4\u00e4 tutkimusta on jonkin verran saatavilla, mutta ne painottuvat ensisijaisesti suurempien markkinapaikkojen havainnointiin pandemian ensivaiheiden aikana. T\u00e4m\u00e4 tutkielma sen sijaan pit\u00e4ytyy suomalaisessa kontekstissa ja tutkiikin Suomessa vallinneen koronatilanteen yhteytt\u00e4 Helsingin p\u00f6rssin p\u00e4\u00e4listan osaketuottoihin vuosina 2020\u20132021 yhti\u00f6kohtaisella tasolla.\n\nTutkimusaineiston pohjana oleva numeromuotoinen data on ladattu julkisista luotettavina pidett\u00e4vist\u00e4 tietokannoista ja sit\u00e4 on k\u00e4sitelty taulukkolaskentaohjelmalla tutkittavaksi tilastollisin menetelmin. Tutkimus on kvantitatiivinen arvorelevanssitutkimus, jonka tutkimusmenetelm\u00e4n\u00e4 on lineaarinen regressioanalyysi. Selitett\u00e4v\u00e4n\u00e4 muuttujana on osakkeen arvonmuutos tutkimusajanjaksona ja selitt\u00e4viksi muuttujiksi on laskettu koronatapausten ja osakkeen p\u00e4\u00e4t\u00f6skurssien v\u00e4lille lasketut koronakorrelaatiokertoimet. Lis\u00e4ksi selitt\u00e4viksi muuttujiksi on sis\u00e4llytetty arvorelevanteiksi arveltuja taloudellisia tunnuslukuja. \n\nTutkimustulosten mukaan sek\u00e4 tauti- ett\u00e4 kuolemantapauksilla on ollut yhteys tutkimusjoukon osaketuottoihin. Koronatartuntatapausten ja osakkeiden p\u00e4\u00e4t\u00f6skurssien v\u00e4lille laskettu korrelaatiokerroin selitt\u00e4\u00e4 parhaiten osakkeiden arvonmuutosta molempina tutkimusperiodin vuosina. Lis\u00e4ksi vuoden 2020 dataan perustuvan parhaimman selitysasteen regressiomalliin sis\u00e4ltyi koronaliit\u00e4nn\u00e4isiin kuolemanlukuihin pohjautuva korrelaatiokerroin. Puolestaan vuoden 2021 regressiomallinnukseen sis\u00e4ltyi tauti- ja kuolemantapauskorrelaatiokertoimen ohella maksuvalmiuden tunnuslukuna k\u00e4ytetty current ratio.
