Title: More Stocks , Less Risk


1
Ch 1 Diversification
  • More Stocks , Less Risk
  • As the number of stocks in a portfolio
    increases, the total risk or volatility of that
    portfolio decreases.

2
Benefits of Diversification
  • Diversification is the act of combining assets
    with dissimilar behavior for the purpose of
    producing a portfolio with an optimal risk/return
    tradeoff.
  • NOT PUTTING ALL YOUR EGGS IN ONE
    BASKET
  • By diversifying, a deep loss in one asset class
    may be offset by gains in another.
  • The net result is a more stable portfolio.

3
Diversification Helps Manage Risk
  • In an ideal world, investors would find
    securities that offer consistently high return
    with little risk. However in the real world there
    is no such thing.

4
International Securities
  • International stocks and bonds are another major
    asset class to consider. There have been some
    instances when foreign securities have
    outperformed their U.S. counterparts.
  • The diversification benefits of international
    securities, have generated high interest in
    global markets. To reduce the total volatility
    risk of some portfolios, it would be wise to
    invest internationally as well.

5
Asset Allocation
  • The most important investment decision is the
    asset mix of a portfolio.
  • The five major asset classes investors are
    concerned with their investment needs are
  • Day-to-Day, Emergencies, Saving for a Near-Term
    Purchase, Long-Term Savings, and Retirement.
  • The understanding of five major investment
    fundamentals aids in a assembling a portfolio
    are
  • Tradeoff between risk and return
  • Diversification Benefits
  • Long-Term Investing and Compounding Returns
  • Liquidity and Marketability Considerations
  • Tax Deferral Benefits
  • However the most important decision is the Asset
    Allocation choice

Ch 2Modern Portfolio Theory (MPT)
  • Prepared by
  • Alex Au

7
Introduction
  • MPT takes into account of different possible
    outcomes, project results with a high degree of
    certainty, have the ability to be fine tuned on a
    regular basis, stay within selected parameter and
    reduce your overall risk.
  • MPT let investors choose their own risk level.
  • MPT work with proper diversification to reduce
    risk and increase return.

8
The Need for Asset Allocation
  • Diversification can reduce a portfolios risk and
    improve return.
  • Since each asset class have a different
    uncertainty it is necessary to consider the range
    of possible outcome for each asset class.

9
Portfolio Risk and Return
  • Investors want a high expected return, but at the
    same time they want an asset with low standard
    deviation.
  • Expected return and standard deviation are
    estimated from historical data.
  • Investors are not concern with holding a asset in
    isolation, but rather with the risk of the entire
    portfolio.

10
(contd)
  • Portfolio risk not only depend on the riskiness
    of its component assets, but also on how the
    return are related to one another.
  • Risk that can be eliminated by diversification
    does not command a risk premium.
  • A portfolios expected rate of return should be
    easy to determine using the weighted average
    return of the individual assets.

11
(contd)
  • Correlation coefficient is the measure of the
    relationship between the rate of return behavior
    of each asset versus every other asset.
  • First-order autocorrelations of a return series,
    is the return in one period that is related to
    the return in the next period.
  • Cross correlations show how much one series
    returns are related to another.

12
(contd)
  • The portfolios risk is a function of the the
    individual assets and their correlation to each
    other.

13
Portfolio Optimization
  • Efficient portfolio have a mixture of assets,
    whereas inefficient portfolio has assets that
    make higher risk-adjusted incremental
    contributions to portfolio return than other
    assets.
  • Efficient frontier refers to the collection of
    all efficient portfolios corresponding to the
    full range of portfolio risk possibilities.

14
Optimizing the Portfolio
  • Once the expected return, standard deviation, and
    cross-correlation have been estimated for the
    asset classes than mathematical calculation to
    derive the asset allocations for portfolios on
    the efficient frontier.
  • Optimal portfolio will always have a subjective
    dimension because there is no way to directly
    measure a clients risk tolerance.

15
(contd)
  • Managers expectation of return on asset class
    may not be in line with the benchmark return,
    therefore it is not recommended that the
    managers returns be used in place of benchmark
    estimates.

16
Symmetrical vs. Asymmetrical Risk Distribution
  • Symmetrical risk distribution uses all the
    optimization software to minimize risk, whereas
    asymmetrical is where the investors are more
    concerned with losses.

17
Why MPT Hasnt Been More Widely Used
  • The software is expensive (from 50,000 to
    200,000 per year).
  • Index funds and foreign funds were not widely
    accessible.
  • Most planners do not have the theoretical and
    practical education to implement MPT.
  • Asset allocation and MPT did not receive
    mainstream press coverage.

18
(contd)
  • MPT calculates different combinations of assets
    that yield the maximum expected return at each
    level of risk, as measured by standard deviation.
  • It is important to understand that the expected
    return, standard deviation and correlation of the
    assets in the portfolio are merely forecasts
    based on past performance.

Ch 3Structuring A Portfolio
  • By Yihui Yu

20
Diversification
  • Objective to add investments to the clients
    portfolio that are not closely related to his
    other investments
  • Measurement correlation coefficients.
  • - coefficient 0 (no direct relationship)
  • - coefficient 1 (perfect positive relation)
  • - coefficient -1 (perfect negative relation)

21
The Correlation Matrix
  • Concept compare one investment o another and
    report the correlation coefficient
  • Investment categories for the matrix
  • - domestic stock
  • - foreign stock
  • - bonds
  • - cash equivalents
  • - real assets

22
Selecting Assets For a Portfolio
  1. The assets that the client refuses to get rid of
    should be included.
  2. Several investment categories are represented.
  3. Each category should comprise at least 5 of the
    portfolio.
  4. Recommended weightings should be rounded off to
    the nearest whole number.

23
Other Factors
  • The type of mutual fund or annuity chosen should
    depend on the following factors
  • Clients time horizon
  • Any existing investment the client already owns
  • Clients goals and objectives
  • Clients risk tolerance level

24
Ch 4 Asset Allocation
25
Definition
  • Asset allocation is the process of distributing
    portfolio investments among the various available
    investment categories.
  • Process involves three decisions
  • 1. Which types of investments should be
    included or excluded?
  • 2. How much weight should be given to each
    asset?
  • 3. Which vehicles should be used?

26
Importance of Asset Allocation
  • If you should have x of a portfolios holdings
    in growth and income funds versus some other
    percentage figure is much more important than
    trying to gauge if ht investment should be made
    now or in six months.

27
Approaches to Asset Allocation
  • Strategic asset allocation is a passive approach
    that focuses on long-range policy decisions to
    determine the appropriate asset mix.
  • It does not attempt to predict or time the
    market. The portfolio is fully invested at all
    times. Risk is reduced by using several different
    investment categories.

28
Approaches to Asset Allocation
  • Tactical asset allocation is an active approach
    that generally uses market predictions to change
    the asset mix in order to exploit superior
    predictive ability through such techniques. This
    strategy believes that market inefficiencies can
    constantly be found and that short-term trading
    can take advantage of such inefficiencies.

29
Approaches to Asset Allocation
  • Dynamic asset allocation is an active technique
    that reacts to changing market conditions by
    making relatively frequent changes in the asset
    mix with the goal of providing downside
    protection in addition to upside participation.

30
Ch 5Market Timing
31
Introduction
  • Essence of market timing in any investment is to
    buy low and sell high
  • Use of leading indicators
  • A blending of business analysis with technical
    projections
  • Reaction to leading indicators sometimes opposite
    of expectations
  • Investors take advantage of market inefficiencies
  • Switching of portfolios of high/low betas
    according to market conditions

32
Methodology Moving Averages
  • Straight or simple moving average is the sum of a
    data series divided by the total units involved
  • Commonly used 30 and 60 day moving averages
  • Exponential moving average is a weighted moving
    average
  • Smoothes out minor fluctuations in trends
  • More reliable

33
Moving Averages (Continued)
  • Two basic rules
  • Buy signals rendered whenever price of fund rises
    above level of moving averages employed
  • Sell signals rendered when price level falls
    below level of moving averages employed

34
Methodology Cash Flow Indicator
  • Based on the concept of contrary thinking
  • Buy at peak pessimism sell at peak optimism of
    market
  • Example Mutual fund cash position
  • Large increase/decrease may indicate bear/bull
    market expectations
  • Historically, rise above 10 leads to major
    upward market move converse at 8 normal at 9

35
Drawbacks to Short-term Trading
  • Market timers have to be right twice when they
    are getting in and again when they are exiting
    the market
  • The more moves, the greater the chance for
    mistakes
  • May lose advantage of deferred taxation

36
Studies Trinity Study
  • Observations on nine peak-to-peak cycles since
    WWII May 29, 1946 through Aug. 25, 1987
  • About 1.7 times more up months than down 309 vs.
    187
  • Average bull market up 104.8 vs. Average bear
    market drop of 28
  • Bull markets last three times as long as bear
    markets 41 up months vs. 14 down months
  • Even in bear markets, on average 3 to 4 months
    out of 10 are up months
  • On average, 8 of 41-month bull market duration
    accounted for 60 of total returns

37
Charles D. Ellis Study
  • All 100 pension funds engaged in some market
    timing
  • Not one improved rate of return
  • 89 of 100 lost as a result of timing

38
William F. Sharpe Study
  • Market study from 1934 to 1972
  • Market timer with 2 in trading costs, choosing
    once a year between stocks and cash, would have
    to be right at least 82 of the time to do as
    well as a buy-and-hold stock investor

39
Chua and Woodward Study
  • To be successful at market timing, investors
    require forecast accuracy for at least
  • 80 of all bull markets, 50 of all bear
    markets
  • 70 of all bull markets, 80 of all bear markets
    or
  • 60 of all bull markets, 90 of all bear markets

40
Robert H. Jeffrey Study
  • If market timing is only accurate 50 of the
    time, probable outcomes
  • Best-case real dollar return, only two times
    greater than from continuous investment in SP
  • Worst-case produces 100 times less.

41
Roy D. Henrikson Study
  • Study on 116 mutual funds from 1968 to 1980
  • Virtually all fund managers showed no significant
    ability to time purchases for superior performance

42
Ibbotson Study
  • Study on security returns from 1949 to 1998
  • If investor missed 5 best years for common stocks
    and invested in T-bills instead, 1 in stocks at
    end of 1925 would only become 127, instead of
    578 if invested continuously in SP 500
  • Point market timer has tremendous natural odds
    to overcome odds increase geometrically with
    length of timeframe and frequency of timing
    interval

43
Timing Services
  • Many investors rely on newsletters or timing
    services for timing signals
  • Timing services also track fund performance and
    recommend specific funds to buy
  • Minimum account 25,000
  • Plus 2 annual management fee

44
Timing vs. Buy-and-Hold
  • Q Which does better?
  • A It depends
  • Performance measurements strongly influenced by
    period of comparison
  • Buy-and-hold is better in upward trend markets
  • Timing is better in declining markets
  • In good markets, all can do well. Therefore,
    timing services may help cut losses

45
Ch 6FORMULA TIMING INDICATORS
  • Introduction-
  • Offers a mechanical timing approach
  • Commonly used substitutes for subjective
    buy-and-sell timing decisions.
  • Requires investor input

46
  • 3 Types of formula plans includes
  • Constant Dollar Plans- requires investor to set
    the dollar value of the aggressive portfolio.
  • Constant Ratio Plan- maintains the value of the
    aggressive portfolio relative to the value of the
    conservative portfolio.
  • Variable Ratio Plan- mechanical portfolio
    management plan that requires extensive
    forecasting.

47
TIMING INDICATORS
  • Bear Market Endings
  • 6 indicators that tell investors when it is time
    to start buying stocks again
  • Investment Sentiment
  • Market P/E
  • Dividend Yield
  • Interest Rates
  • Market Volume
  • Advances and Declines

48
  • Stocks in a recession 1973-1975
  • In 1973-75 during the beginning of the recession,
    there was a 7.8 growth in the S P 500.
  • In 1980 there was a 14.6 growth
  • In 1981-82 there was a 16.5 growth.

49
  • Markets in a recession 1948-1991
  • There have been 9 business recessions since the
    end of World War II.

50
PREDICTABILITY
  • Businesses tend to occur in most major nations
    about twice in each 10-year period.
  • National Bureau of Economic Research is one of
    the most respected economic organizations to
    study business cycles.

51
BEARS
  • Bear markets is any market when share prices
    reach a two-year low.
  • Bear markets occur about twice every 10 years
  • The best way to predict a bear market may be to
    realize bear markets end when least expected

52
BULLS
  • A bull market is defined any time when share
    prices reach a two-year high.

    16 months)
  • Ninth Postwar Recession- July 1990 to March 1991
    (9 months)

57
Predictability
  • Business recession tend to occur in most major
    nations about twice in each 10-year period, but
    we have never been able to find any person or
    organization who could correctly predict either
    bear markets or business recessions.

58
Bears and Bulls
  • A bear market is defines as any market when share
    prices reach a two-year low.
  • A bull market is defined any time when share
    prices reach a two-year high.

59
Ch 8 Security Analysis
60
Introduction
  • The capital asset pricing model and efficient
    markets theory has been demonstrated both
    theoretically and empirically that
    diversification reduces the risk of a portfolio.

61
Modern Portfolio Theory
  • Markowitz showed that investor should hold
    diversified portfolios containing financial
    assets that are less than positively correlated
    with each other.
  • William Sharpe, John Lintner and Jan Mossin
    extended this theory called Capitail Asset
    Pricing Model.

62
CAPM
  • CAPM provides a theory of the relationship
    between securities and portfolio rates of returns
    and those of a representative market index that
    is a proxy for the overall stock market.
  • Betas are calculated using past security and
    portfolio data and hence are simply estimates of
    future relationships.

63
Stock Selection
  • Neither chart reading (technical analysis) nor
    analysis of corporate financial statements
    (fundamental analysis) can provide above-average
    investment returns on a risk-adjusted basis.

64
Fundamental Analysis
  • The fundamental analysts tools indlude
    macro-economic data, corporate financial reports,
    industry data, and comments from corporate
    officers and company memoranda.looking to
    determine whether a specific companys stock is
    undervalued or overvalued.

65
Technical Analysis
  • Technical approach involves the use of past price
    and volume and other external data to assess the
    crowds attitude toward the market and specific
    stocks.

66
Chapter 9Rebalancing the Portfolio
  • The Need for Rebalancing
  • -if the portfolio is not rebalanced one asset
    could achieve dominance
  • -Rebalancing keeps the portfolio diversified

67
  • Approaches to Reevaluation
  • -buy-and-hold strategy- do nothing at all
  • -calendar approach- rebalance the portfolio back
    to its original allocations i.e. monthly,
    quarterly annually
  • -contingent approach- make changes based on
    pre-specified percentage change in allocations
    from o.g. policy

68
  • Rebalancing Experimentation
  • -Let it Ride Study
  • --study performed without transaction costs
    or industry fees
  • --rebalancing doesnt help the portfolio on
    either a return or risk basis

69
  • -Stine and Lewis Study
  • --considered transaction costs
  • --rebalancing does lower risk, while
    sacrificing little return in exchange
  • --annual rebalancing makes more sense than
    quarterly rebalancing
  • --the best option is the contingent strategy,
    with the asset varying more than 7.5 to 10
    from o.g. position

70
  • -Clifton Study
  • --considered all costs
  • --annually rebalanced outperformed
    buy-and-hold and contingent strategies on a
    risk-to-reward basis

71
  • -Short Holding Period Study
  • --transaction costs included
  • --contingent strategy, with asset varying
    7-10 from o.g. position produces less risk
    than annual rebalancing, requires fewer
    rebalances and lower transaction costs

72
  • Conclusions
  • -rebalance only when a portfolio reaches a
    predetermined level of risk exposure
  • -because the contingent strategy is easy to
    monitor and requires no sophisticated
    programming, management costs are minimal
  • -if the portfolio manager does elect a calendar
    strategy, annual balancing produces the best
    results

73
  • Compensation
  • -a portfolio manager should regularly bill
    clients for re-optimization, even if its
    infrequent
  • -if a manager is monitoring clients investments
    and communicating regularly, they should be paid

74
Ch 10 Asset Allocation Sensitivity
75
Introduction
  • Overall, U.S. equities had excellent return in
    the 1980s and 1990s. Foreign equities performed
    fairly well during these two decades.
  • It is well known by MPT followers that of the
    three components that comprise the model program
    (historical returns, standard deviations and
    correlation coefficients)

76
Sensitivity to Expected Returns
  • Although managed futures, venture capital, oil
    and gas, and other limited partnerships have very
    good historical returns, they still have some
    shortcoming of each of these investments.
  • -guru, bank brokerage firm, insurance company, or
    financial planning group had such information ,
    they certainly wouldnt share it with you. Also
    industry users and insiders know more about you
    or any trader knows in future market or other
    market.

77
Review Individual Asset Statistics
  • Whenever or wherever you see a return or standard
    deviation figure that you strongly doubt, note
    it. But it assumes that you have done research
    not just based on experience or recent history.

78
The 5/25 Strategy
  • By selecting at least 5 different asset
    categories and investing at least 5, but no more
    25.
  • Dont rely entirely on the program that suggests
    a large investment in one of these categories.
