Abstract [en]

The purpose of this study is to investigate the effects of COVID-19 initial hit and the associated lockdowns effect on the semiconductor industry. The study emanates from factors of return on investment in the equity market using the CAPM model alongside the theories of EMH and behavioral finance. The semiconductor industry is represented by the SOX index, and the S&P 500 index representing the general markets. The mapping of movements in these indexes are done in a daily time series between 01/01/2018 to 29/11/2021 to find out the behavior of the market during a period of shock. The conclusion is that equity markets is affected by lockdowns, but also has other factors affecting the industry.

Abstract [sv]

Syftet med denna studie är att undersöka effekterna av COVID-19 och karantänregleringar på halvledarindustrin. Studien utgår från faktorer som risk och avkastning på aktiemarknaden genom att använda CAPM-modellen tillsammans med teorierna EMH och beteendeekonomi. Skiftet på aktiemarknaden observeras genom risk och avkastning på SOX-indexet som representerar halvledarindustrin och S&P 500-indexet som representerar de allmänna marknaderna. Kartläggningen av rörelser i dessa index görs i en daglig tidsserie mellan 01/01/2018 och 29/11/2021 för att ta reda på om det är värt att investera i halvledarindustrin under pandemin. Slutsatsen är att aktiemarknaderna kan överreagera på nyheter och att halvledarmarknaden initialt är motståndskraftig mot covid-19. Marknadensmotståndskraft följs dock av längre prissvängningar som resulterar i högre avkastning och lägre risk vilket gör investeringar i halvledarindustrin betydligt bättre än S&P 500.
