(1)Financial assets are expected to generate cash flows and hence the riskiness of a financial asset is measured in terms of the riskiness of its cash flows. (2)The riskiness of an asset may be measured on a stand-alone basis or in a portfolio context. An asset may be very risky if held by itself but may be much less risky when it is a part of a large portfolio. (3)In the context of a portfolio‚ the risk of an asset is divided into two parts: diversifiable risk (unsystematic risk) and market risk

Assignment 1. Returns and Risk Estimate and compare the returns and variability (i.e. annual standard deviation over the past five years) of Reynolds and Hasbro with that of the S&P 500 Index. Which stock appears to be riskiest? Reynolds appears to be the riskiest stock based on the returns and variability alone currently holding the highest average return out of two at 1.87%. With their higher return rate over the three they also hold the highest standard deviation of 9.1%‚ which in turn

Returns 1 RETURNS Prices and returns Let Pt be the price of an asset at time t. Assuming no dividends the net return is Pt Pt − Pt−1 −1= Rt = Pt−1 Pt−1 The simple gross return is Pt = 1 + Rt Pt−1 Returns 2 Example: If Pt−1 = 2 and Pt = 2.1 then 2.1 Pt 1 + Rt = = = 1.05 and Rt = 0.05 Pt−1 2 Returns 3 The gross return over k periods (t − k to t) is 1 + Rt (k) := Pt−1 Pt−k+1 Pt Pt ··· = Pt−k Pt−1 Pt−2 Pt−k = (1 + Rt ) · · · (1 + Rt−k+1 ) Returns are • scale-free‚ meaning that they do not depend
