A group of investors was polled each week for the last five

A group of investors was polled each week for the last five weeks about whether they were bullish or bearish concerning the market. Construct the market sentiment index for the first week.  (Do not round intermediate calculations. Round your answers to 4 decimal places.)

Solution

MSI_{week 1} = Bears/(Bulls + Bears)

= 69/(61 + 69) = 69/130 = 0.5308
