The probability of an expansion is 50%, and the probability of a recession is 50%. There is a 2x leveraged market ETF (you can think of this as a stock) which doubles the market portfolio return. In other words, in expansion, it has a 10% return, and in recession, it has a 10% return. What is the correlation between the market portfolio and the 2x leveraged market ETF? A. -1 B. -0.5 C. 0 D. 0.5 E. 1
