Abstract
This paper explores the impact of global events on global economy from both economical and natural perspectives. In this paper, we have collected the stock data of 10 firms from the S&P 500 and the impact of the Great Recession and the COVID-19 pandemic on them will be explored and analyzed. The 10 firms can be sorted into 4 fields: technology company (NVIDIA Corporation, Cisco Systems, Inc Intel Corporation), financial services (The Goldman Sachs, Group, Inc. U.S. Bancorp, The Toronto-Dominion Bank, The Allstate Corporation), consumer defensive (The Procter & Gamble Company, Colgate-Palmolive Company), and healthcare product producer (Johnson & Johnson). According to the analysis, the features of the portfolio are discussed. These results shed light on guiding further exploration focusing on portfolio design based on multi-assets in terms of hedging risks. This paper utilized several financial tools to analyze the stock price of the selected firms, for example, Markowitz model. By doing such data-based research, the behaviors of stock prices of the firms when encountering major global events have been revealed. The data processing in this research are primary based on Excel, a Microsoft software that enable us to construct data into diagrams, or process using the same method at the same time as a whole.
