Risk and Risk Aversion • Risk, Speculation, and Gambling • Risk Aversion and Utility Values • Estimating Risk Aversion
Risk and Risk Aversion • Risk, Speculation, and Gambling • Risk: The chance that an investment's actual return will be different than expected. • Speculation: the assumption consider-able investment risk to obtain commensurate gain ▫ Considerable = the risk is sufficient to affect the decision • Gamble = bet or wager on an uncertain outcome ▫ Speculation gambling

Risk and Risk Aversion • Variance and Standard Deviation p -1 – (-p) = p-1 1 -p 2 ( r ) = p (1 -p) 0 - (-p) = p (6. 3)
Capital Allocation across Risky and Risk -Free Portfolios • The risk of long-term Bonds > the risk of T-Bills Ready Asset Money Market Fund Initial portfolio W to total $ 90, 000 Equities (30%) $ 113, 400 (54%) . 378 $ 300, 000 Risky Securities $ 210, 000 Long-Term bonds (70%) $ 96, 600 (46%) . 322. 70

E( R p ) + (1 -y) r f = rf + y [ E (rp) –rf ]= 7 + y ( 15 -7) = 7 + 8 y (6. 8)

16 Portfolios of One Risky Asset and a Risk -Free Asset Bodi Kane Marcus Ch 5 • If investor: ▫ Invest solely in the risky asset; y = 1 ; the complete portfolio = P ▫ Invest y = 0; (1 -y) = 1; the complete portfolio = the risk free portfolio = F ▫ The extra return per extra risk = 8/22 =. 36
17 Bodi Kane Marcus Ch 5 Portfolios of One Risky Asset and a Risk -Free Asset • The extra return per extra risk = 8/22 E(r. C)= rf +y [ E (rp) –rf ] = rf + c / p [ E (rp) –rf] = 7 + 8/22 c (6. 10)

22 Bodi Kane Marcus Ch 5 Note Fig 6. 7 • Steeper curve (kurva yang lebih curam) menandakan investor menuntut peningkatan expected return untuk setiap satuan tambahan risiko atau investor relatif lebih enggan terhadap risiko • The higher curve (kurva pada posisi lebih tinggi) menunjukkan tingkat kepuasan yang lebih tinggi
23 Bodi Kane Marcus Ch 5 Table 6. 6 • Expected return of : �Given Risk Aversion (A) �Given Utility (U) �Certain Standard Deviation ( ) • Higher risk (standard deviation) higher Expected return • It is possible the same risk aversion (A= 4) has different Utility (U =. 05 and U=. 09)
