Resumo: Investors like to have the possibility of very high returns, even if they are highly unlikely. Because of this, they prefer positively skewed assets, which are consequently overvalued generating lower returns. This work studies the implications of extraordinarily skewed returns in the cross-sectional pricing of stocks in light of previous evidence that investors favor assets with lottery-like payoffs and the fact that many investors are inadequately diversified. Analyzing data from US stocks since 1927 I found that, realized skewness has an economically important and statistically significant negative relationship with expected stock returns. This realized-skewness sorted strategy rewards its investors with an average monthly return of 0.7% with a corresponding t-stat of 27.2 and a Sharpe Ratio of 0.89, with certain unexpected calendar months – April and July – outperforming the market with Sharpe ratios of 1.5 and 2.24, respectively. My findings are of interest to investors as this strategy is easy to implement and this work lays out the path for further academic research regarding skewness related trading strategies.

Por isso, eles preferem ativos positivamente assimétricos, que consequentemente são sobrevalorizados, o que gera retornos inferiores. Este trabalho estuda as implicações de retornos extraordinariamente assimétricos de ações, de acordo com estudos anteriores que concluíram que muitos dos investidores estão inadequadamente diversificados e preferem ativos com retornos semelhantes aos de uma loteria. Ao analisar os dados de ações dos EUA desde 1927, descobri que a assimetria realizada tem uma relação negativa economicamente importante e estatisticamente significativa com os retornos esperados das ações. Essa estratégia recompensa seus investidores com um retorno mensal médio de 0,7% com um t-stat correspondente de 27,2 e um índice de Sharpe de 0,89, com alguns meses do calendário inesperados – abril e julho – a baterem o mercado com os índices de Sharpe de 1,5 e 2,24, respetivamente. O presente trabalho tem relevância para os investidores, dado que esta estratégia é fácil de implementar e estabelece a base para estudos académicos adicionais sobre estratégias de investimento relacionadas à assimetria.Faias, José AfonsoVeritati - Repositório Institucional da Universidade Católica PortuguesaAbrantes, João Rafael Pereira Gaspar Mendes2023-06-26T07:11:10Z2023-01-262023-012023-01-26T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10400.14/41423TID:203277910enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-07-12T17:47:00Zoai:repositorio.ucp.pt:10400.14/41423Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T18:34:07.032144Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
