Question C2
Ken is a junior stock analyst for an investment firm. He believes that stock returns are highly determined by the value, leverage and profitability of a company. With that, he decides to conduct a cross-sectional regression on the following variables.
Ri = stock returns for stock i BMi = book-to-market ratio for stock i DEi = debt-to-equity ratio for stock i ROEi = return on equity for stock i
The table below shows the output extract of the multiple linear regression for a cross- section of 20 randomly selected stocks on the local stock exchange.
