Suppose that we construct a market value-weighted index of three stocks. We have the following information one month ago about these stocks:

• ConocoPhillips (COP): market value weight = 0.20; share price = $69
• ExxonMobil Corp. (XOM): market value weight = 0.50; share price = $86
• Halliburton Co. (HAL): market value weigh = 0.30; share price = $47

Today, we have the following information:

• ConocoPhillips (COP): share price = $80; dividend per share just paid: $1
• ExxonMobil Corp. (XOM): share price = $93; dividend per share just paid: $1
• Halliburton Co. (HAL): share price = $63; dividend per share just paid: $2

What is the total return on a market value-weighted portfolio of the three stocks for this past month?

Enter your answer as a decimal rate of return. Enter 3 decimal places of accuracy. If the portfolio return is negative, then include a minus sign in your answer. (If positive, do not include a sign.)
