  21. Basics of Portfolio Theory • Factors affecting asset demand • Relative return • Relative risk • Liquidity • Income FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  22. Basics of Portfolio TheoryBasic Calculations • Capital Gain • Selling price (V1) less purchase price (V0) • Percentage Change (%) • [(V1 - V0) / V0]  100 • Return • Sum of capital gains and other payments (P) during holding period as fraction of purchase price V0 • [(V1 - V0) / V0 + P/ V0]  100 FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  23. Basics of Portfolio Theory • Risk • Uncertainty of future return • Liquidity • Ease and cost of selling asset for cash FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  24. Basics of Portfolio Theory • Relative Return • http://www.biz.uiowa.edu/iem/markets/compdata/compfund.html FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  25. Basics of Portfolio Theory • Liquidity • Ease and cost of selling asset for cash • Example: compare two assets • 3-month certificate of deposit (CD) • Savings deposit held for 3 months • The CD is less liquid because must pay a penalty to withdraw money early FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  26. Basics of Portfolio Theory Evaluating Uncertain Returns • Pool example • 100 people each pay $1 to participate in a pool. Each places their name in the hat. A single name is drawn. That person receives the pool of $100. • Possible outcomes • win $100 • win $0 • Probabilities of outcomes • win $100 - 1/100 • win $0 - 99/100 FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  27. Basics of Portfolio Theory Evaluating Uncertain Returns • Pool example (continued) • Expected Value, EV • EV = (P$100 × $100) + (P$0 × $0) • EV = (1/100× $100) + (99/100 × $0) • EV = $1 • Fair bet EV = price • To participate in pool, pay $1. EV of participation = $1. • Fair bet. • Would you participate? FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  28. Basics of Portfolio Theory Evaluating Uncertain Returns • Expected Value is a way to evaluate an uncertain payoff. • How much would you be willing to pay for a 1/100 chance to win $1000? • Expected value is $10. • How much would you be willing to pay for a 1/100 chance of winning $100,000? • Expected value is $1,000 FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  29. Basics of Portfolio Theory Evaluating Uncertain Returns • Why were fewer willing to play for $100,000 than for $100? • Both were fair bets in that the price equaled the expected value. • Risk Averse - weigh losses more heavily than gains. • Risk averse traders must be compensated to take on risk (pay less than expected return). FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  30. Basics of Portfolio Theory Evaluating Uncertain Returns • Risk averse traders must be compensated to take on risk. • The expected return is the expected value of uncertain returns • Because traders are risk averse, they will pay less for an asset than its expected return. FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  31. Basics of Portfolio Theory Evaluating Uncertain Returns • Suppose two assets with same expected value of $25 • Asset 1 pays • $50 with probability 1/2 • $0 with probability 1/2 • Asset 2 pays • $30 with probability 1/2 • $20 with probability 1/2 • Which would you prefer? • Which is more risky? FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  32. Basics of Portfolio Theory Evaluating Uncertain Returns • Risk concerns the variation in outcomes. • Demand for assets decreases with risk. FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  33. Basics of Portfolio Theory Evaluating Uncertain Returns • Standard Deviation is a measure of risk. • Measures how close the returns are to the expected returns. • Data are monthly returns and standard deviations from April 1995 to October 1999 FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  34. Monthly Returns for Apple and IBM, Jan. 1997 to Oct. 1999 FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/

  35. Summary • Markets come in many shapes and sizes • Trading strategies vary • Demand for an asset is related to return, risk, liquidity and income FALL 2000 EDITION LAST EDITED ON 9/00 WWW.BIZ.UIOWA.EDU/IEM/ASSIGNMENTS/
