One year ago, Matt bought 100 shares of ACE Corp. stock for $5,619 including commission. He is about to sell the ACE stock for $6,528 net of commissions. When he made the purchase the S&P 500 index was at 907; now it is 1070. The beta of ACE stock is 0.98, and the market's risk-free rate is 4.0%. No dividends were paid. Based on Jensen's measure, did Matt make a good purchase?
