Calculate ROE and P/B
Before we can analyze the relation between ROE and P/B, we have to first calculate these variables. In this exercise, we will use data for the Consumer Discretionary firms that are in the S&P 400 Midcap Index, which are stored in the cons_disc object. The values for ltm_eps, bvps, and price for each firm are also stored in cons_disc.
