  1. Chapter 15Revision of the Equity Portfolio

  2. An individual can make a difference; a team can make a miracle - 1980 U.S. Olympic hockey team

  3. Outline • Introduction • Active management versus passive management • When do you sell stock?

  4. Introduction • Portfolios need maintenance and periodic revision: • Because the needs of the beneficiary will change • Because the relative merits of the portfolio components will change • To keep the portfolio in accordance with the investment policy statement and investment strategy

  5. Active Management Versus Passive Management • Definition • The manager’s choices • Costs of revision • Contributions to the portfolio

  6. Definition • An active management policy is one in which the composition of the portfolio is dynamic • The portfolio manager periodically changes: • The portfolio components or • The components’ proportion within the portfolio • A passive management strategy is one in which the portfolio is largely left alone

  7. The Manager’s Choices • Leave the portfolio alone • Rebalance the portfolio • Asset allocation and rebalancing within the aggregate portfolio • Change the portfolio components • Indexing

  8. Leave the Portfolio Alone • A buy and hold strategy means that the portfolio manager hangs on to its original investments • Academic research shows that portfolio managers often fail to outperform a simple buy and hold strategy on a risk-adjusted basis • E.g., Barber and Odean show that investors who trade the most have the lowest gross and net returns

  9. Rebalance the Portfolio • Rebalancing a portfolio is the process of periodically adjusting it to maintain the original conditions

  10. Rebalancing Within the Portfolio • Constant mix strategy • Constant proportion portfolio insurance • Relative performance of constant mix and CPPI strategies

  11. Constant Mix Strategy • The constant mix strategy: • Is one to which the manager makes adjustments to maintain the relative weighting of the asset classes within the portfolio as their prices change • Requires the purchase of securities that have performed poorly and the sale of securities that have performed the best

  12. Constant Mix Strategy (cont’d) Example A portfolio has a market value of $2 million. The investment policy statement requires a target asset allocation of 60 percent stock and 30 percent bonds. The initial portfolio value and the portfolio value after one quarter are shown on the next slide.

  13. Constant Mix Strategy (cont’d) Example (cont’d) What dollar amount of stock should the portfolio manager buy to rebalance this portfolio? What dollar amount of bonds should he sell?

  14. Constant Mix Strategy (cont’d) Example (cont’d) Solution: a 60%/40% asset allocation for a $2.5 million portfolio means the portfolio should contain $1.5 million in stock and $1 million in bonds. Thus, the manager should buy $100,000 worth of stock and sell $100,000 worth of bonds.

  15. Constant Proportion Portfolio Insurance • A constant proportion portfolio insurance (CPPI) strategy requires the manager to invest a percentage of the portfolio in stocks: $ in stocks = Multiplier x (Portfolio value – Floor value)

  16. Constant Proportion Portfolio Insurance (cont’d) Example A portfolio has a market value of $2 million. The investment policy statement specifies a floor value of $1.7 million and a multiplier of 2. What is the dollar amount that should be invested in stocks according to the CPPI strategy?

  17. Constant Proportion Portfolio Insurance (cont’d) Example (cont’d) Solution: $600,000 should be invested in stock: $ in stocks = 2.0 x ($2,000,000 – $1,700,000) = $600,000 If the portfolio value is $2.2 million one quarter later, with $650,000 in stock, what is the desired equity position under the CPPI strategy? What is the ending asset mix after rebalancing?

  18. Constant Proportion Portfolio Insurance (cont’d) Example (cont’d) Solution: The desired equity position after one quarter should be: $ in stocks = 2.0 x ($2,200,000 – $1,700,000) = $1,000,000 The portfolio manager should move $350,000 into stock. The resulting asset mix would be: $1,000,000/$2,200,000 = 45.5%

  19. Relative Performance of Constant Mix and CPPI • A constant mix strategy sells stock as it rises • A CPPI strategy buys stock as it rises

  20. Relative Performance of Constant Mix & CPPI (cont’d) • In a rising market, the CPPI strategy outperforms constant mix • In a declining market, the CPPI strategy outperforms constant mix • In a flat market, neither strategy has an obvious advantage • In a volatile market, the constant mix strategy outperforms CPPI

  21. Relative Performance of Constant Mix & CPPI (cont’d) • The relative performance of the strategies depends on the performance of the market during the evaluation period • In the long run, the market will probably rise, which favors CPPI • In the short run, the market will be volatile, which favors constant mix

  22. Rebalancing Within the Equity Portfolio • Constant proportion • Constant beta • Change the portfolio components • Indexing

  23. Constant Proportion • A constant proportion strategy within an equity portfolio requires maintaining the same percentage investment in each stock • May be mitigated by avoidance of odd lot transactions • Constant proportion rebalancing requires selling winners and buying losers

  24. Constant Proportion (cont’d) Example A portfolio of three stocks attempts to invest approximately one third of funds in each of the stocks. Consider the following information:

  25. Constant Proportion (cont’d) Example (cont’d) After one quarter, the portfolio values are as shown below. Recommend specific actions to rebalance the portfolio in order to maintain the constant proportion in each stock.

  26. Constant Proportion (cont’d) Example (cont’d) Solution: The worksheet below shows a possible revision which requires an additional investment of $1,000:

  27. Constant Beta Portfolio • A constant beta portfolio requires maintaining the same portfolio beta • To increase or reduce the portfolio beta, the portfolio manager can: • Reduce or increase the amount of cash in the portfolio • Purchase stocks with higher or lower betas than the target figure • Sell high- or low-beta stocks • Buy high- or low-beta stocks

  28. Change the Portfolio Components • Changing the portfolio components is another portfolio revision alternative • Events sometimes deviate from what the manager expects: • The manager might sell an investment turned sour • The manager might purchase a potentially undervalued replacement security

  29. Indexing • Indexing is a form of portfolio management that attempts to mirror the performance of a market index • E.g., the S&P 500 or the DJIA • Index funds eliminate concerns about outperforming the market • The tracking error refers to the extent to which a portfolio deviates from its intended behavior

  30. Costs of Revision • Introduction • Trading fees • Market impact • Management time • Tax implications • Window dressing • Rising importance of trading fees

  31. Introduction • Costs of revising a portfolio can: • Be direct dollar costs • Result from the consumption of management time • Stem from tax liabilities • Result from unnecessary trading activity

  32. Trading Fees • Commissions • Transfer taxes

  33. Commissions • Investors pay commissions both to buy and to sell shares • Commissions at a brokerage firm are a function of: • The dollar value of the trade • The number of shares involved in the trade

  34. Commissions (cont’d) • The commission on a trade is split between the broker and the firm for which the broker works • Brokers with a high level of production keep a higher percentage than a new broker • Some brokers discount their commissions with their more active clients

  35. Commissions (cont’d) • Discount brokerage firms: • Offer substantially reduce commission rates • Offer few ancillary services, such as market research • Retail commissions at a full-service firm average about 2 percent of the stock value

  36. Transfer Taxes • Transfer taxes are: • Imposed by some states on the transfer of securities • Usually very modest • Not normally a material consideration in the portfolio management process

  37. Market Impact • The market impact of placing the trade is the change in market price purely because of executing the trade • Market impact is a real cost of trading • Market impact is especially pronounced for shares with modest daily trading volume

  38. Management Time • Most portfolio managers handle more than one account • Rebalancing several dozen portfolios is time consuming

  39. Tax Implications • Individual investors and corporate clients must pay taxes on the realized capital gains associated with the sale of a security • Tax implications are usually not a concern for tax-exempt organizations

  40. Window Dressing • Window dressing refers to cosmetic changes made to a portfolio near the end of a reporting period • Portfolio managers may sell losing stocks at the end of the period to avoid showing them on their fund balance sheets

  41. Rising Importance of Trading Fees • Flippancy regarding commission costs is unethical and sometimes illegal • Trading fees are receiving increased attention because of: • Investment banking scandals • Lawsuits regarding churning • Incomplete prospectus information

  42. Contributions to the Portfolio • Periodic additional contributions to the portfolio from internal or external sources must be invested • Dividends: • May be automatically reinvested by the fund manager’s broker • May have to be invested in a money market account by the fund manager

  43. When Do You Sell Stock? • Introduction • Rebalancing • Upgrading • Sale of stock via stop orders • Extraordinary events • Final thoughts

  44. Introduction • Knowing when to sell a stock is a very difficult part of investing • Behavioral evidence suggests the typical investor sells winners too soon and keeps losers too long

  45. Rebalancing • Rebalancing can cause the portfolio manager to sell shares even if they are not doing poorly • Profit taking with winners is a logical consequence of portfolio rebalancing

  46. Upgrading • Investors should sell shares when their investment potential has deteriorated to the extent that they no longer merit a place in the portfolio • It is difficult to take a loss, but it is worse to let the losses grow

  47. Sale of Stock Via Stop Orders • Definition • Using stops to minimize losses • Using stops to protect profits

  48. Definition • Stop orders: • Are sell stops • Become a market order to sell a set number of shares if shares trade at the stop price • Can be used to minimize losses or to protect a profit

  49. Using Stops to Minimize Losses • Stop-loss orders can be used to minimize losses • E.g., you bought a share for $23 and want to sell it if it falls below $18 • Place a stop-loss order for $18

  50. Using Stops to Protect Profits • Stop orders can be used to protect profits • E.g., a stock you bought for $33 now trades for $48 and you want to protect the profits at $45 • If the stock retreats to $45, you lock in the profit if you place a stop order • If the stock continues to increase, you can use a crawling stop to increase the stop price
