Title: Quote from Siri


1
Quote from Siri
  • I hate the way they teach Math in the school.
    All the teacher does is put lots of examples on
    the board for the students to memorize.
  • He does not explain the theory so that we could
    apply the theory to ANY numbers rather than
    memorizing 10 problems without understanding.
  • I much prefer learning why and how and working
    different problems hands on, like at my school at
    home, rather than memorizing specific problems
    that Ill never see after school

COB Policies Review
  • B. College of Business Policies and Procedures,
    which will be enforced.
  •  
  • To ensure that every student, current and future,
    who takes courses in the Boccardo Business Center
    has the opportunity to experience an environment
    that is safe, attractive, and otherwise conducive
    to learning, the College of Business at San José
    State has established the following policies
  •  
  • Eating
  • Eating and drinking (except water) are prohibited
    in the Boccardo Business Center.  Students with
    food will be asked to leave the building. 
    Students who disrupt the course by eating and do
    not leave the building will be referred to the
    Judicial Affairs Officer of the University.
  •  
  • Cell Phones
  • Students will turn their cell phones off or put
    them on vibrate mode while in class.  They will
    not answer their phones in class.  Students whose
    phones disrupt the course and do not stop when
    requested by the instructor will be referred to
    the Judicial Affairs Officer of the University.
  •  
  • Computer Use
  • In the classroom, faculty will allow students to
    use computers only for class-related activities. 
    These include activities such as taking notes on
    the lecture underway, following the lecture on
    Web-based PowerPoint slides that the instructor
    has posted, and finding Web sites to which the
    instructor directs students at the time of the
    lecture.  Students who use their computers for
    other activities or who abuse the equipment in
    any way, at a minimum, will be asked to leave the
    class and will lose participation points for the
    day, and, at a maximum, will be referred to the
    Judicial Affairs Officer of the University for
    disrupting the course.  (Such referral can lead
    to suspension from the University.)  Students are
    urged to report to their instructors computer use
    that they regard as inappropriate (i.e., used for
    activities that are not class related).
  •  
  • Academic Honesty
  • Faculty will make every reasonable effort to
    foster honest academic conduct in their courses. 
    They will secure examinations and their answers
    so that students cannot have prior access to them
    and proctor examinations to prevent students from
    copying or exchanging information.  They will be
    on the alert for plagiarism.  Faculty will
    provide additional information, ideally on the
    green sheet, about other unacceptable procedures
    in class work and examinations.  Students who are
    caught cheating will be reported to the Judicial
    Affairs Officer of the University, as prescribed
    by Academic Senate Policy S98-1.

My Policies
  • C. My Class Room Policies1. Due to assistance in
    adhering to COB policies and to the demonstrated
    by past classes learning/attendance benefits
    it affords, classes will be run as back to back
    sessions with the break at the end. Thus the
    classes will run as follows130 to 350/55
    (with break from 355 to 415)530 to 750/55
    (with break from 755 to 815)2. Class will
    go full time. If something runs shorter than
    anticipated, an unscheduled class exercise that
    will further enhance learning will be added 3.
    Short courteous bio breaks are allowed during
    the class EXCEPT during exams.4. Courtesy to
    your class mates and the professor requires
    on-time arrival and informing the professor of
    early departures or missing class ahead of time
    (due to in class group exercises)

7
Why I do things the way I do..
  • From industry looking to teach something that
    will help you on the job and, hopefully, ensure
    it is not exported offshore.
  • Six 6-hour exams at end of HS (at 18) on
    EVERYTHING ever learned Only tools pencil,
    eraser, slide rule. No M/C
  • CMA exam (Four 4-hour exams no M/C), PLUS CPIM,
    CIRM and PMP exams

Primary GoalsChallenge to Grow
  • Improve Analytical/Modeling SkillsPLUS
  • Deepen/Expand Discipline Specific Knowledge
    SkillsPLUS
  • Prepare for lifelong learningEQUALS
  • Work and Career Preparation

Schedule/Key Dates
  • Exam Dates1. Feb 21 (Ch 1-8)2. Mar 21 (Ch 9-14,
    25)3. Final Date, Wed May 23 (do NOT book
    flights earlier, no exceptions will be made)
  • Jeopardy DateMay 2

10
Grading
11
What grades are possible
  • All grades from A to F
  • Grades are based on points at the end of the
    semester (break point system)

12
So, how do I get an A?
  • A typical A student in this class has the
    following profile Thinks of themselves as a
    responsible adult and likes being treated as such
    Works hard AND smart (usually had high grades
    in previous classes for the same reasons) uses
    time management tools Submits work on time
    without excuses or whining Tries to solve
    problems that, on the surface, may seem like
    new because they are in an unfamiliar format or
    ask for new information Asks questions when
    does not understand Fully participates in in
    class team exercises, etc.

13
Can I fail this class?
  • Of course.
  • A student who fails this class typically Feels
    like school work interferes with other more
    important activities/feels entitled to a C or
    above regardless. Has a poor record (lots of
    C-/D/F/U/W) when I check Feels professors
    should focus on only what will be on exam, and
    spoon feed all answers and that cheat sheets
    should be allowed etc. Use lots of excuses for
    not doing work/missing class Does not
    contribute to the in class exercises choosing to
    talk about other matters during them

14
Why dont you show us exactly how to do the
analysis and forecast and give right answer and
test on the same numbers?
  • Answer You are here to learn how to approach a
    problem when you have not done exactly that
    problem before but have learned the tools
    previously.
  • Do you suppose your boss would pay you if he/she
    had to do the project first?
  • In real life, there are no single right answers

15
TOOO Much Work? Ch 1-3Review from 170, mostly
16
  • The basic goal of management to create
    stock-holder value (measured by stock price!!!)
  • Agency relationships get in the way
  • 1. Stockholders versus managers
  • 2. Stockholders versus creditors

17
What is an agency relationship?
  • An agency relationship arises whenever one or
    more individuals, call (1) hires another
    individual or organization, to perform some
    service (2) delegates decision-making authority
    to that agent.

18
There are TWO potential agency conflicts
  • Conflicts between stockholders and managers.
  • Conflicts between stockholders and creditors.

19
Would going public in an IPO increase or decrease
agency problems?
.
20
Why might you want to inflate your reported
earnings or use off balance sheet financing to
make your financial position look stronger?
  • A manager might inflate a firm's reported
    earnings or make its debt appear to be lower if
    he or she wanted the firm to look good
    temporarily. For example just prior to
    exercising stock options or raising more debt.

21
What are the potential consequences of inflating
earnings or hiding debt?
  • If the firm is publicly traded, the stock price
    will probably drop once it is revealed that fraud
    has taken place. If private, banks may be
    unwilling to lend to it, and investors may be
    unwilling to invest more money.

22
What kind of compensation program might you use
to minimize agency problems?
  • Reasonable annual salary to meet living
    expenses
  • Cash (or stock) bonus
  • Options to buy stock or actual shares of stock to
    reward long-term performance
  • Tie bonus/options to EVA

23
EVA????
  • Economic Value Added
  • Profit over and beyond paying for the cost of
    capital
  • NOPAT - Cost of Capital
  • NOPATEBIT-Taxes
  • Cost of Capital Capital (NWCFA) WACC
  • Capital CA-CLFALTDEquity (CAFACLDE)
  • CofC cost of debt after tax, cost of equity,
    impact of risk
  • How do you impact the components???

24
Why might someone interviewing for an entry level
job have a better shot at getting a good job if
he or she had a good grasp of financial
management?
  • Managers want to hire people who can make
    decisions with the broader goal of corporate
    value maximization in mind because investors are
    forcing top managers to focus on value
    maximization.

25
What are investment returns?
  • Investment returns measure the financial results
    of an investment.
  • Returns may be historical or prospective
    (anticipated).
  • Returns can be expressed in
  • .
  • .

26
What is the return on an investment that costs
1,000 and is soldafter 1 year for 1,100?
  • Dollar return ?
  • Percentage return ?

27
What is investment risk?Risk Return Tradeoff
  • Investment returns are not known with certainty.
  • Risk refers to the probability of earning a
    return different from that expected.
    Variability of outcome.
  • The greater the chance of a return far below the
    expected return, the greater the risk. The
    corollary is that, typically, there is also
    probability of high return.

31
What is the standard deviationof returns for
each alternative?
32
  • Standard deviation measures the stand-alone risk
    of an investment.
  • The larger the standard deviation, the higher
    the probability that returns will be far below
    the expected return.
  • Coefficient of variation is an alternative
    measure of stand-alone risk.

36
Two-Stock Portfolios
  • Two stocks can be combined to form a riskless
    portfolio if r -1.0.
  • Risk is not reduced at all if the two stocks have
    r 1.0.
  • In general, stocks have r ? 0.65, so risk is
    lowered but not eliminated.
  • Investors typically hold many stocks.
  • What happens when r 0?

37
What would happen to the risk of an average
1-stock portfolio as more randomly selected
stocks were added?
  • ?p would decrease because the added stocks would
    not be perfectly correlated, but rp would remain
    relatively constant.

Risk Stand-alone, Market, Diversifiable
Market risk is that part of a securitys
stand-alone risk that cannot be eliminated by
diversification. Firm-specific, or diversifiable,
risk is that part of a securitys stand-alone
risk that can be eliminated by diversification.
41
Conclusions
  • As more stocks are added, each new stock has a
    smaller risk-reducing impact on the portfolio.
  • ?p falls very slowly after about 40 stocks are
    included. The lower limit for ?p is about 20
    ?M .
  • By forming well-diversified portfolios, investors
    can eliminate about half the riskiness of owning
    a single stock.

42
Can an investor holding one stock earn a return
appropriate to its risk?
  • No. Rational investors will minimize risk by
    holding portfolios.
  • They bear only market risk, so prices and returns
    reflect this lower risk.
  • The one-stock investor bears higher (stand-alone)
    risk, so the return is less than that required by
    the risk.

43
How is market risk measured for individual
securities?
  • Market risk, which is relevant for stocks held in
    well-diversified portfolios, is defined as the
    contribution of a security to the overall
    riskiness of the portfolio.
  • It is measured by a stocks beta coefficient.
  • In addition to measuring a stocks contribution
    of risk to a portfolio, beta also measures the
    stocks volatility relative to the market.

44
What is the CAPM from 170?
  • The CAPM is an equilibrium model that specifies
    the relationship between risk and required rate
    of return for assets held in well-diversified
    portfolios.
  • It is based on the premise that only one factor
    affects risk.
  • What is that factor?

45
What are the assumptions of the CAPM?
  • Investors all think in terms ofa single holding
    period.
  • All investors have identical expectations.
  • Investors can borrow or lend unlimited amounts at
    the risk-free rate.

(More...)
46
  • All assets are perfectly divisible.
  • There are no taxes and no transactions costs.
  • All investors are price takers, that is,
    investors buying and selling wont influence
    stock prices.
  • Quantities of all assets are given and fixed.

47
How are betas calculated?
  • Run a regression line of past returns on Stock i
    versus returns on the market.
  • The regression line is called the characteristic
    line.
  • The slope coefficient of the characteristic line
    is defined as the beta coefficient.

48
Regression to Estimate Beta
  • Run a regression with returns on the stock in
    question plotted on the Y axis and returns on the
    market portfolio plotted on the X axis.
  • The slope of the regression line, which measures
    relative volatility, is defined as the stocks
    beta coefficient, or b.

49
Calculating Beta in Practice
  • Many analysts use the SP 500 to find the market
    return.
  • Analysts typically use four or five years of
    monthly returns to establish the regression line.
  • Some analysts use 52 weeks of weekly returns.

50
How is beta interpreted?
  • If b 1.0, stock has average risk.
  • If b gt 1.0, stock is riskier than average.
  • If b lt 1.0, stock is less risky than average.
  • Most stocks have betas in the range of 0.5 to
    1.5.
  • Can a stock have a negative beta?

51
Finding Beta Estimates on the Web
  • Go to www.bloomberg.com.
  • Enter the ticker symbol for a Stock Quote, such
    as IBM or Dell.
  • When the quote comes up, look in the section on
    Fundamentals.

Method of Calculation
  • Analysts use a computer with statistical or
    spreadsheet software to perform the regression.
  • At least 3 years of monthly returns or 1 years
    of weekly returns are used.
  • Many analysts use 5 years of monthly returns.

61
Interpreting Regression Results
  • The R2 measures the percent of a stocks variance
    that is explained by the market. The typical R2
    is
  • 0.3 for an individual stock
  • over 0.9 for a well diversified portfolio

62
Interpreting Regression Results (Continued)
  • The 95 confidence interval shows the range in
    which we are 95 sure that the true value of beta
    lies. The typical range is
  • from about 0.5 to 1.5 for an individual stock
  • from about .92 to 1.08 for a well diversified
    portfolio

63
  • Betas of individual securities are not good
    estimators of future risk.
  • Betas of portfolios of 10 or more randomly
    selected stocks are reasonably stable.
  • Past portfolio betas are good estimates of future
    portfolio volatility.

64
  • CAPM/SML concepts are based on expectations, yet
    betas are calculated using historical data. A
    companys historical data may not reflect
    investors expectations about future riskiness.
  • Other models are being developed that will one
    day replace the CAPM, but it still provides a
    good framework for thinking about risk and return.
