Make an overview for each firm. What are the major products of these firms? Who are the main competitors of the firm? (Note that “competitor” means offering similar goods or services to the same potential customers.)In addition to the qualitative description above, we will want the following quantitative information about each firm: stock market capitalization, debt ratio1, and standard risk measures: both beta and (annualized) volatility. These can be calculated with data easily downloadable from Yahoo! Finance, under Historical Data, and Key Statistics. (Calculate these, do not just report Yahoo! Finance’s calculations.) Beta and volatility calculations should be based on data (use log returns) from 1/1/2011 to 1/1/2021. Use (ten years of) both weekly and daily data and average the results. (If the company had an IPO or was spun off in the last ten years, use data starting from the first January 1 after the IPO/spinoff, and note the shorter sample.) Beta should be calculated against the S&P 500 index (ticker ^SPXor ^GSPC).
Debt ratio = (Debt – Cash)/(Debt – Cash + Stock market capitalization)
