Expected Returns I. • Expected return is the “weighted average” return on a risky asset
Because grants do not earn returns. Acumen Fund accounts for the sunk costs of the grant and admin- istration in the denominator of the expected return formula

The expected return of the portfolio is still the weighted average of the expected returns of the individual securities We may express it as E(R p) = w 1 E(R 1) + w 2 E(R 2) + w 3 E(R 3) Likewise we may construct the expression for the ? of a three-security portfolio First
• Total Return = expected return + unexpected return • Unexpected return = systematic portion + unsystematic portion • Therefore total return can be expressed as follows: • Total Return = expected return + systematic portion + unsystematic portion
any expected return This was the cental insight of Markowitz who (in his framework) recognized that investors seek to minimize variance for a given level of expected return or equivalently they seek to maximize expected return for a given constraint on variance Before formulating and solving the mean variance problem consider Figure 1 below
Expected Returns with RN Probs • Note that we can rearrange the risk-neutral pricing equation price = discounted “expected” payoff as • I e “expected” return = the riskless rate (Here return is un-annualized ) • Thus with the risk-neutral probabilities all assets have the same expected return--equal to the riskless rate
We can think of returns as being decomposed into expected returns and unexpected returns More formally: R t = E t?1 (R t) + e t (1) where R t is return in period t E t?1 (R t) is expected return at t conditional on information available at t-1 e t is unexpected return
