1. Go to finance.yahoo.com and download the ending monthly stock prices for FLIR systems(FLIR) for the last 60 months. Be sure to use the adjusted closing price to account for any stock splits and dividend payments. Next, download the ending value of the S&P 500 index over the same period.

Alphai, is the regression intercept and Betai is the slope. Et represents the residuals for the regression. What do you think is the motivation for this particular regression? The intercept AlphaI is often called jensen’s alpha. What does it measure? If an asset has a positive Jensen’s alpha, where would it plot with respect to the SML? What is the financial interpretation of the residuals in the regression?,,3. Use the market model to estimate the beta for FLIR systems using the last 60 months of returns. PLot the monthly returns on FLIR Systems against the index and also show the fitted line.,,4. Compare your beta for FLIR systems to the beta you find on finance.yahoo.com. How similar are they?
