So for my dissertation I need to discuss the impact of presidential campaigns on stock price volatility and I need some advice on which test or methodology to use? (not very sophisticated if possible).
Speaking with my supervisor, I know my independent variable will be the before/after of the launch date (0 for the 60 trading days preceding the launch; and 1 for the 30 days after the launch) and the dependent variable is the stock price volatility. I also have a couple control variables such as the number of employees of the companies as well as the revenues.
I already collected the data and started working on stata but I am unsure how to proceed. All suggestions are welcome :)
