Introduction Active management versus passive

management When do you sell stock?

2

Introduction Portfolios need maintenance and

periodic revision:Because the needs of the beneficiary will

changeBecause the relative merits of the portfolio

components will changeTo keep the portfolio in accordance with the

investment policy statement and investment strategy

3

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

4

Definition An active management policy is one in

which the composition of the portfolio is dynamicThe 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

5

The Manager’s Choices Leave the portfolio alone Rebalance the portfolio Asset allocation and rebalancing within

the aggregate portfolio Change the portfolio components Indexing

6

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

7

Rebalance the Portfolio Rebalancing a portfolio is the process

of periodically adjusting it to maintain the original conditions

8

Rebalancing Within the Portfolio Constant mix strategy Constant proportion portfolio insurance Relative performance of constant mix

and CPPI strategies

9

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

10

Constant Mix Strategy (cont’d)

Example

A portfolio has a market value of Rs2 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.

11

Constant Mix Strategy (cont’d)

Example (cont’d)

What Rs amount of stock should the portfolio manager buy to rebalance this portfolio? What Rs amount of bonds should he sell?

12

Date Portfolio Value Actual Allocation Stock Bonds

1 Jan Rs2,000,000 60%/40% Rs1,200,000

Rs800,000

1 Apr Rs2,500,000 56%/44% Rs1,400,000

Rs1,100,000

Constant Mix Strategy (cont’d)

Example (cont’d)

Solution: a 60%/40% asset allocation for a Rs2.5 million portfolio means the portfolio should contain Rs1.5 million in stock and Rs1 million in bonds. Thus, the manager should buy Rs100,000 worth of stock and sell Rs100,000 worth of bonds.

13

Constant Proportion Portfolio Insurance A constant proportion portfolio

insurance (CPPI) strategy requires the manager to invest a percentage of the portfolio in stocks:

Rs in stocks = Multiplier x (Portfolio value – Floor value)

14

Constant Proportion Portfolio Insurance (cont’d)

Example

A portfolio has a market value of Rs2 million. The investment policy statement specifies a floor value of Rs1.7 million and a multiplier of 2.

What is the Rs amount that should be invested in stocks according to the CPPI strategy?

15

Constant Proportion Portfolio Insurance (cont’d)

Example (cont’d)

Solution: Rs600,000 should be invested in stock:

Rs in stocks = 2.0 x (Rs2,000,000 – Rs1,700,000)

= Rs600,000

If the portfolio value is Rs2.2 million one quarter later, with Rs650,000 in stock, what is the desired equity position under the CPPI strategy? What is the ending asset mix after rebalancing?

16

Constant Proportion Portfolio Insurance (cont’d)

Example (cont’d)

Solution: The desired equity position after one quarter should be:

Rs in stocks = 2.0 x (Rs2,200,000 – Rs1,700,000)

= Rs1,000,000

The portfolio manager should move Rs350,000 into stock. The resulting asset mix would be: Rs1,000,000/Rs2,200,000 = 45.5%

17

Relative Performance of Constant Mix and CPPI A constant mix strategy sells stock as it

rises

A CPPI strategy buys stock as it rises

18

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

19

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

20

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

21

Constant Proportion A constant proportion strategy within

an equity portfolio requires maintaining the same percentage investment in each stockMay be mitigated by avoidance of odd lot

transactions

Constant proportion rebalancing requires selling winners and buying losers

22

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:

23

Stock Price Shares Value % of Total Portfolio

FC 22.00 400 8,800 31.15

HG 13.50 700 9,450 33.45

YH 50.00 200 10,000 35.40

Total Rs28,250

100.00

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.

24

Stock Price Shares Value % of Total Portfolio

FC 20.00 400 8,000 21.92

HG 15.00 700 10,500 28.77

YH 90.00 200 18,000 49.32

Total Rs36,500 100.00

Constant Proportion (cont’d)

Example (cont’d)

Solution: The worksheet below shows a possible revision which requires an additional investment of Rs1,000:

YH 90.00 200 18,000 Sell 50 13,500 36.00

Total Rs36,500 Rs37,500 100.00

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

portfolioPurchase stocks with higher or lower betas than

the target figureSell high- or low-beta stocksBuy high- or low-beta stocks

26

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 sourThe manager might purchase a potentially

undervalued replacement security

27

Indexing Indexing is a form of portfolio management

that attempts to mirror the performance of a market indexE.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

28

Costs of Revision

Introduction Trading fees Market impact Management time Tax implications Window dressing Rising importance of trading fees

29

Introduction

Costs of revising a portfolio can:Be direct Rs costsResult from the consumption of

management timeStem from tax liabilitiesResult from unnecessary trading activity

30

Trading Fees

Commissions Transfer taxes

31

Commissions

Investors pay commissions both to buy and to sell shares

Commissions at a brokerage firm are a function of:The Rs value of the tradeThe number of shares involved in the trade

32

Commissions (cont’d) The commission on a trade is split

between the broker and the firm for which the broker worksBrokers with a high level of production keep

a higher percentage than a new broker

Some brokers discount their commissions with their more active clients

33

Commissions (cont’d)

Discount brokerage firms:Offer substantially reduce commission ratesOffer few ancillary services, such as market

research

Retail commissions at a full-service firm average about 2 percent of the stock value

34

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

35

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

36

Management Time

Most portfolio managers handle more than one account

Rebalancing several dozen portfolios is time consuming

37

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

38

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

39

Rising Importance of Trading Fees Flippancy regarding commission costs is

unethical and sometimes illegal

Trading fees are receiving increased attention because of:Investment banking scandalsLawsuits regarding churningIncomplete prospectus information

40

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 brokerMay have to be invested in a money market

account by the fund manager

41

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

42

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

43

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

44

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

45

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

46

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

47

Using Stops to Minimize Losses Stop-loss orders can be used to

minimize lossesE.g., you bought a share for Rs23 and want

to sell it if it falls below Rs18○ Place a stop-loss order for Rs18

48

Using Stops to Protect Profits Stop orders can be used to protect

profitsE.g., a stock you bought for Rs33 now

trades for Rs48 and you want to protect the profits at Rs45○ If the stock retreats to Rs45, 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

49

Extraordinary Events

Change in client objectives Change in market conditions Buy-outs Caprice

50

Change in Client Objectives The client’s investment objectives may

change occasionally:E.g., a church needs to generate funds for a

renovation and changes the objective for the endowment fund from growth of income to income○ Reduce the equity component of the portfolio

51

Change in Market Conditions Many fund managers seek to actively

time the market

When a portfolio manager’s outlook becomes bearish, he may reduce his equity holdings

52

Buy-Outs

A firm may be making a tender offer for one of the funds holdingsI.e., another firm wants to acquire the fund

holding

It is generally in the client’s best interest to sell the stock to the potential acquirer

53

Caprice

Portfolio managers:Should be careful about making

unnecessary tradesMust pay attention to their experience,

intuition, and professional judgment

An experienced portfolio manager worried about a particular holding should probably make a change

54

Final Thoughts Hindsight is an inappropriate

perspective for investment decision makingEverything you do as a portfolio manager

must be logically justifiable at the time you do it

Portfolio managers are torn between minimizing losses and the potential for price appreciation
