Resumo: O presente trabalho investiga a presença do efeito overconfidence (excesso de confiança) no mercado acionário de cinco maiores empresas do setor de extração de petróleo listadas na bolsa de Nova York (Exxon, Chevron, EOG Resources, Conoco, Diamondback), no período de 2021 a 2025. Para tanto, são aplicados métodos econométricos fundamentados em modelos de vetores autorregressivos (VAR), com o objetivo de analisar as relações defasadas entre o retorno das ações e o turnover, bem como a influência de variáveis externas, como o preço do barril WTI e o índice S&P500, sobre o comportamento das ações nos períodos que foram confirmados a presença do efeito. A pesquisa busca compreender os mecanismos que caracterizam a manifestação desse viés comportamental, contribuindo para a literatura de Finanças Comportamentais ao examinar como expectativas excessivamente otimistas dos investidores podem afetar o retorno e o volume negociado. Além disso, o estudo identifica padrões temporais e intensidade do efeito overconfidence por meio da utilização de ferramentas como a Função Impulso-Resposta (FIR) e a decomposição da variância, permitindo avaliar sua duração e relevância estatística em diferentes horizontes temporais. Foi constatada a presença do efeito overconfidence em 18 bimestres, dentre as cinco empresas, com maior frequência da presença do viés no ano de 2021 e 2024, e também observando maior incidência nas empresas de grande porte, Exxon e Chevron. Constatou-se também que o barril WTI e o índice S&P500 exerceram influência significativa no retorno das ações nos bimestres onde o excesso de confiança dos investidores esteve presente.

Abstract: This work analyzes the relationships between variations in fixed assets and accounting/financial variables, market prices, and energy consumption of six companies in the Brazilian electricity sector — Neoenergia, Energisa, Equatorial, CPFL, Celesc, and Copel — between 2012 and 2025. The objective is to understand how infrastructure investments impact economic and operational performance in a sector characterized by high capital intensity and strong regulation. The research is quantitative, based on secondary data, and uses stationarity tests (ADF), Vector Autoregressive (VAR) models, and linear regressions to identify contemporaneous and lagged relationships between the variables. The results show that national energy consumption is the main determinant of variations in fixed assets, with long-term lags between four and eleven quarters. The relationship between fixed assets, net worth, and debt reveals different financing strategies, highlighting Copel and Celesc as companies with mixed structures and Energisa as predominantly equity-based. The analyses also point to a strong dependence between operating costs and investments in structural assets of the sector, with short- and medium-term impacts, and between profit and fixed assets, with short-term impacts (2 to 5 quarters). It is concluded that the sector's financial decisions are long-term and depend on predictability to ensure sustainability and efficiency.

Currently, the global financial market has been marked by intense periods of volatility, generating significant uncertainty for investors. One of the strategies frequently adopted to mitigate these risks is investing in assets with high dividend yields. However, the effectiveness of this approach is still debated in academia, without a consolidated consensus. Therefore, this research aimed to investigate, using Markowitz's Modern Portfolio Theory, the efficiency of a strategy based on high dividends and broad asset diversification, segmenting stocks according to their negative shock volatility model (Garch, Egarch, and Tgarch), considering a long-term projection (until 2029), under different allocation scenarios. The results were compared to the performance of the control portfolio, composed of low dividend yield stocks, and to the Ibovespa index, in order to analyze in greater depth the returns provided by portfolios that offer high dividend distribution to shareholders.

Este trabalho tem como objetivo analisar o impacto das variáveis climáticas no preço do café arábica no estado do Espírito Santo, utilizando dados de 2018 a 2022. A pesquisa adota uma abordagem quantitativa e utiliza técnicas de modelagem de a análise de séries temporais, como Vetores Autoregressivos (VAR), decomposição da variância e Função Impulso-Resposta, para identificar a relação entre as variáveis climáticas e o preço do café. A análise revelou que variáveis como precipitação, pressão atmosférica e radiação não têm impacto significativo sobre o preço do café. Em contrapartida, a temperatura de bulbo e a temperatura de orvalho mostraram-se variáveis com forte impacto, especialmente em defasagens temporais de 1 a 6 meses.

Este trabalho tem como proposta a avaliação do valor econômico da Braskem, uma empresa de capital aberto relevante do setor de petroquímico brasileiro, através da aplicação do método do Fluxo de Caixa Descontado. A avaliação considera uma análise estratégica da companhia que examina o posicionamento competitivo da companhia, tendências de mercado, riscos setoriais e oportunidades de crescimento e usa esse insumo como base para definir premissas e consolidar cenários que fundamentam as projeções dos fluxos financeiros e a taxa de desconto. Dessa forma, os fluxos de caixa futuros são trazidos a valor presente, permitindo mensurar o valor real das ações da empresa de acordo com os cenários propostos. Além disso, para complementar o modelo do FCD, aplicou-se a Avaliação por Múltiplos para a comparação dos resultados obtidos.

O progressivo aumento da eletrificação de automóveis, juntamente com o crescimento populacional e o avanço de novas tecnologias, faz com que a demanda por energia elétrica aumente cada vez mais. Além disso, acontecimentos mundiais, como a pandemia da COVID-19, podem impactar diretamente essa demanda, como ocorreu com a diminuição do consumo de energia elétrica em alguns períodos. No segmento de transmissão de energia no Brasil, a receita proveniente das operações vem da Receita Anual Permitida (RAP), um valor fixo recebido pela prestação do serviço de transmissão. O recebimento da RAP depende da disponibilidade das linhas de transmissão, e não do volume de energia transportado. Nesse contexto, o presente estudo propõe-se a avaliar a influência na receita líquida da TAESA S.A., empresa do segmento de transmissão de energia elétrica, considerando a variação de variáveis contábeis internas e de variáveis econômicas externas.

The current challenging environment demands an agile capacity to adapt to new ventures, highlighting the importance of identifying opportunities. However, a lack of planning and market analysis can result in unsuccessful ventures. Therefore, it becomes crucial to conduct a strategic and economic analysis to reduce the chances of failure in an uncertain context. This study, carried out using an exploratory case study methodology, aims to analyze the strategic and economic factors essential to the success of a new company focused on road freight transport, with an emphasis on serving the state of Santa Catarina and headquarters in Itajaí.
Author: Mickael Saadi de Penedo. Advisor: Professor Daniel Christian Henrique. Final work for the undergratuation published in the UFSC Institutional Repository. Since 2019, there has been a progressive relaxation in the reduction of requirements to migrate from the Regulated Contracting Environment to the Free Energy Market, resulting in an expansion of the latter and a reduction in the former. Free consumers who negotiate their conditions are obliged to guarantee, through contracts, that their entire energy load is met. Thus, it is known that these consumers will need to sign agreements to sell energy, but it is not known when this will occur or what factors intensify the demand for these buyers. Therefore, the present study aims to evaluate the purchasing behavior of consumers from an energy supplier in the Free Contracting Environment.

A pandemia da covid-19 gerou sérios percalços financeiros e de saúde pública no mundo, aumentando a mortalidade e o desemprego, principalmente no primeiro ano de 2020, advindo dos lockdowns, assim como forçando 151 nações a criarem auxílios de renda emergenciais até o desenvolvimento e aplicação do ciclo vacinal completo. Ingressando no ano de 2022, houve uma volta à “normalidade”, mantendo-se um convívio com as novas variantes que até hoje rondam (com as atuais cepa Éris e Arcturus espalhando-se rapidamente pelo mundo). Este estudo, portanto, objetivou analisar o impacto que o número total de casos e de mortes gerados pela covid-19 ocasionou na variação da parcela da população que vive em extrema pobreza no mundo entre 2020 e 2022, assim como sua relação com as variações do Índice de Desenvolvimento Humano (IDH) e do PIB Per Capita dos países. Adicionalmente, este estudo é uma adaptação e evolução da pesquisa de Vitenu-Sackey e Barfi (2021) que analisou variáveis equivalentes, porém aplicadas somente aos meses iniciais da pandemia nos quais o mundo ainda se adaptava a esse novo contexto econômico, social e sanitário. Os dados foram obtidos no Our World In Data (2023), que coleta e organiza dados de fontes públicas de organizações mundiais de credibilidade, abordando dados do Banco Mundial, OMS e ONU. Como metodologia, optou-se nesta pesquisa pela geração de regressões com uso de Inteligência Artificial via uso de Machine Learning para melhor acuracidade dos coeficientes, do R2 e da normalidade dos resíduos, possibilitando uma análise mais assertiva.

The ice cream sector in Brazil has a strong growth potential, surpassing the Gross Domestic Product (GDP) growth projections for the coming years. Given these perspectives, the present study aims to carry out the economic-financial analysis for the opening of a new unit of a consolidated ice cream shop in Brasília. Five scenarios were analyzed with applications of uncertainty analysis, considering positive, moderate and negative variations in relation to factors such as rent increase, milk cost increase, GDP growth, climate change and rent increase combined with GDP growth . Taking into account the geopolitical and economic uncertainties, as well as the low probability of acceptable return for the new business, as well as the existence of several investment options that could guarantee returns above the basic interest rate with low risk, it was decided that it would not be feasible to start the new enterprise.

The scenario established in mid-2019, which established a pandemic state due to COVID-19, had a strong impact on the global economy, establishing new forms of consumption and significantly changing the consumer profile. For the textile sector, such changes were strongly felt and the perceived drop in revenues during the period was evident. The present work proposes to analyze revenue projections using different demand forecasting methods for different companies in the textile sector after the pandemic easing period. Short-term projections were analyzed using Machine Learning metrics and statistics for time series, considering that the models would make the necessary weights in view of the strong changes in net revenues that the pandemic period caused in the textile sector. It was adopted as a premise that at the time of data collection, the flexibility scenario would be associated with the active presence of Covid-19.

The objective of this extension study was to separate the operators of public drinking water supply in small municipalities in the states of Santa Catarina and Rio Grande do Sul in 2022 (the last period made available by the National Sanitation Information System - SNIS (2026) referring to this public data) into clusters, according to their common characteristics related to the operational and financial aspects of this activity. The study did not delve into the collection and analysis of data from service providers that only offered "Sewage" services, nor from those that operated "Water + Sewage," even reducing the scope of institutions analyzed, due to the various differences in costs and expenses that sewage infrastructure generates for these companies or for the resources of the responsible public departments, which could create a strong bias in the results when analyzing those that operate exclusively in the "Water" category. Furthermore, future studies are recommended to generate clusters for these two other areas of basic sanitation in municipalities.

By Daniel Christian Henrique and Arthur Fermiano Gallate Ribeiro (Probolsas scholarship recipients). The main objective of this extension report was to compare the qualitative demand for consumer credit (observed and expected) calculated using Central Bank indicators with projections made purely using quantitative metrics and machine learning, for the pre-pandemic period. Other secondary objectives were sequentially allocated throughout the findings obtained. This first report will focus exclusively on the pre-pandemic period. A second report is under development and will be released in the future with the same objectives, but focused on the post-pandemic period. The years of Covid-19 were excluded because it was something unpredictable that could not be foreseen beforehand, generating abrupt changes in people's financial behavior, as well as in their daily lives and ways of working.
Por Daniel Christian Henrique e Arthur Fermiano Gallate Ribeiro (bolsista de extensão Probolsas. O ouro continuaria atuando como hedge nos momentos atuais de forte volatilidade dos mercados mundiais? Apesar de muita resiliência dos mercados mundiais no período pós-pandemia, incluindo o S&P500 quase dobrando suas pontuações nos últimos cinco anos (Larsen, 2025), as altas e baixas das bolsas de valores destes anos começaram a se destacar, gerando um forte fluxo de entrada e saída de recursos entre os diversos ativos financeiros em seus momentos de maior estresse, na busca de maior segurança em seus investimentos. Essas volatilidades atuais são oriundas de uma conjunção de fatores geopolíticos e econômicos ao redor do mundo, podendo serem destacados: as elevadas tarifações dos EUA às importações das demais nações, guerras no leste europeu e Oriente Médio que se alastram vagarosamente e sem perspectivas reais de trégua e dificuldades dos Bancos Centrais em controlar as inflações de seus países, gerando constantes taxas de juros em patamares elevados; dentre outras questões pontuais de política e economia de cada nação. Neste contexto, este estudo buscou averiguar dois objetivos: (1) Analisar uma possível cointegração de longo prazo entre as flutuações dos preços do ouro com o índice VIX e com o S&P500; (2) Analisar nos períodos de curtíssimo prazo com elevadas altas no índice VIX se o ouro atuou como hedge e o sentido de reação do mercado acionário norte-americano.

The AnalyticPro Spreadsheet (provisional name) is a powerful financial tool in Microsoft Excel for project and enterprise cash flow projections developed at GPFA by Prof. Dr. Daniel Christian Henrique. After a few years of construction, the spreadsheet could now be validated in projections of real and simulated projects arising from monograph research.
One of the biggest advantages of this spreadsheet in relation to the software found on the market is its total integration with financial theories, with integrated and pre-designed tabs to meet the different phases of a direct cash flow. Notably, it has already entered as one of the best spreadsheets for financial projection in the national academic environment.
The spreadsheet supports the inclusion of up to 35 products or services, with the possibility of splitting the revenues and costs; SAC or PRICE financing; separation between direct, indirect costs and expenses; projection for a predictable period of up to 30 years plus another 30 years of unpredictable period - totaling 60 years of cash flow. Offers the option of taxation by real or simple national profit.
The projections of changes in future cash flows can be differentiated for each product, type of tax, revenue, costs or expenses, facilitating the generation of optimistic, probable or pessimistic estimates as the fluctuations in the main variables of the project are simulated.
The spreadsheet already supports performing scenario analyzes, sensitivity analyzes and Monte Carlo simulations. However, the possibility of greater automation in the inputs of the variation data and generation of the resulting cash flows is in progress.
The AnalyticPro Spreadsheet is exclusive for use in research, not for sale. In the future, at the end of its development, we intend to adapt it to HTML or in executable to facilitate the use in GPFA research and guidelines in other universities.
