a possible research topic
A Possible Research Topic
  • It is sometimes said that correlations between stocks increases when the market is tanking
  • The goal is to explore the empirical relationship between coefficient of correlation between various stocks of similar industries and market returns
  • Process:
    • Match up individual stocks’ data and S&P data
    • Partition data into periods to be analyzed (by week, by month, etc.)
    • Calculate the market returns for each period
    • Calculate the coefficient of correlation of returns (hourly, daily, etc) between stocks for each period
    • Plot coefficient of correlation against returns and find a relationship
another possible research topic
Another Possible Research Topic
  • Find relationship between beta and market returns
  • Process:
    • Match up individual stocks’ data and S&P data
    • Partition data into periods to be analyzed (by week, by month, etc.)
    • Calculate time variant realized betas over periods
    • Calculate the market returns for each period
    • Plot realized betas vs. market returns and find a relationship
