4. Risk, return and financial markets We can examine returns in the financial markets to help us determine the appropriate returns on non-financial assets. Lessons from capital market history: – There is a reward for bearing risk. – The greater the potential reward, the greater the risk. – This is called the risk–return trade-off. 10-4 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al. Slides prepared by David E. Allen and Abhay K. Singh

5. Dollar returns Total dollar return = the return on an investment measured in dollars. $ return = Dividends + Capital gains Capital gains = Price received – Price paid Example: – You bought a bond for $950 one year ago. You have received two coupons of $30 each. You can sell the bond for $975 today. What is your total dollar return? Income = 30 + 30 = $60 Capital gain = 975 – 950 = $25 Total dollar return = 60 + 25 = $85 10-5 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al. Slides prepared by David E. Allen and Abhay K. Singh

6. Percentage returns It is generally more intuitive to think in terms of percentages than dollar returns. Total percentage return = the return on an investment measured as a percentage of the original investment. – % return = $ return/$ invested 10-6 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al.

8. Calculating returns Example 10.1 You invest in a stock with a share price of $25. After one year, the stock price per share is $35. Each share paid a $2 dividend. What was your total return? 10-8 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al. Slides prepared by David E. Allen and Abhay K. Singh DollarsPercentage Dividend$2.00$2/25 = 8% Capital gain$35 - $25 = $10$10/25= 40 % Total return$2 + $10 = $12$12/$25 = 48%

18. Risk 10-18 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al. Slides prepared by David E. Allen and Abhay K. Singh Risk is measured by the dispersion, spread or volatility of returns. Figure 10.9— Frequency distribution of returns on the All Ordinaries Index, 1985–2009

19. Return variability review Variance = VAR(R) or σ 2 – Common measure of return dispersion – Also call variability Standard deviation = SD(R) or σ – Square root of the variance – Sometimes called volatility – Same ‘units’ as the average 10-19 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al.

26. Arithmetic vs geometric mean Arithmetic average – Return earned in an average period over multiple periods – Answers the question: ‘What was your return in an average year over a particular period?’ Geometric average – Average compound return per period over multiple periods – Answers the question: ‘What was your average compound return per year over a particular period?’ Geometric average < arithmetic average, unless all the returns are equal. 10-26 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al.

27. Geometric average return: Formula 10-27 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al. Slides prepared by David E. Allen and Abhay K.

29. Arithmetic vs geometric mean Which is better? The arithmetic average is overly optimistic for long horizons. The geometric average is overly pessimistic for short horizons. Depends on the planning period under consideration – 15–20 years or less: use arithmetic average – 20–40 years or thereabouts: split the difference between them – 40 + years: use the geometric average 10-29 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al.

30. Efficient capital markets The efficient market hypothesis – Stock prices are in equilibrium – Stocks are ‘fairly’ priced – Informational efficiency If true, you should not be able to earn ‘abnormal’ or ‘excess’ returns. Efficient markets DO NOT imply that investors cannot earn a positive return on the stock market. 10-30 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al.

32. What makes markets efficient? There are many investors out there doing research. – As new information comes to market, this information is analysed and trades are made based on this information. – Therefore, prices should reflect all available public information. If investors stop researching share prices, the market will no longer be efficient. 10-32 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al. Slides prepared by David E. Allen and Abhay K. Singh

33. Common misconceptions about EMH EMH does not mean that you can’t make money. EMH does mean that: – on average, you will earn a return appropriate for the risk undertaken – there is no bias in prices that can be exploited to earn excess returns – market efficiency will not protect you from wrong choices if you do not diversify—you still don’t want to put all your eggs in one basket 10-33 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al.

34. Forms of market efficiency Strong-form efficient market Information = public or private ‘Inside information’ is of little use Semistrong-form efficient market Information = publicly available information Fundamental analysis is of little use Weak-form efficient market Information = past prices and volume data Technical analysis is of little use 10-34 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al. Slides prepared by David E. Allen and Abhay K. Singh

35. Strong-form efficiency Prices reflect all information, including public and private. If the market were strong-form efficient, investors could not earn abnormal returns regardless of the information they possessed. Empirical evidence indicates that markets are NOT strong-form efficient and that insiders can earn abnormal returns. 10-35 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al. Slides prepared by David E. Allen and Abhay K. Singh

36. Semistrong-form efficiency Prices reflect all publicly available information, including trading information, annual reports and press releases. If the market is semistrong-form efficient, investors cannot earn abnormal returns by trading on public information. Implies that fundamental analysis will not lead to abnormal returns. 10-36 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al. Slides prepared by David E. Allen and Abhay K. Singh

37. Weak-form efficiency Prices reflect all past market information such as price and volume. If the market is weak-form efficient, investors cannot earn abnormal returns by trading on market information. Implies that technical analysis will not lead to abnormal returns. Empirical evidence indicates that markets are generally weak-form efficient. 10-37 Copyright ©2011 McGraw-Hill Australia Pty Ltd PPTs t/a Essentials of Corporate Finance 2e by Ross et al.
