LỜI NÓI ĐẦU 
Hiện nay trong chương trình đào tạo ngành Kế toán của Học viện Công nghệ Bưu chính 
Viễn thông ngoài những môn học hướng tới ngành đào tạo còn có những môn học sử dụng tài 
liệu tiếng Anh chuyên ngành như “CFA”, “Introduction to ACCA”. Những môn học này 
ngoài việc bổ sung kiến thức tiếng Anh chyên ngành còn cung cấp kiến thức tài chính kế toán 
theo hướng cập nhật các chuẩn mực quốc tế. Tuy nhiên với vốn tiếng Anh còn hạn chế của 
sinh viên Học viện, đã tạo ra không ít khó khăn trong công tác giảng dạy và học tập các môn 
học này. Nhận thấy vấn đề như trên, kết hợp với chủ trương của Học viện thực hiện biên soạn 
bài giảng, giáo trình, slide cho các môn học nhằm đồng bộ hóa tài liệu, tác giả đã thực hiện 
biên soạn bài giảng “CFA” dành riêng cho giảng viên và sinh viên ngành kế toán của Học 
viện. 
Bài giảng được thực hiện biên soạn trên tinh thần tiếp thu nội dung mới nhất những kiến 
thức từ chứng chỉ tài chính quốc tế CFA và kế thừa phát huy những điểm mạnh trong bài 
giảng của những trường đại học danh tiếng đồng thời dựa trên những kinh nghiệm thực tế 
giảng dạy của tác giả. Bài giảng đã hệ thống những nội dung theo đề cương chi tiết đã được 
Học viện ban hành: Corporate Finance, Market Organization, Equity Analysis and Valuation, 
Portfolio Management 
Để bài giảng thực sự trở thành tài liệu hữu ích phục vụ cho hoạt động giảng dạy và học 
tập, tác giả mong muốn nhận được những góp ý với tinh thần xây dựng, chia sẻ chân thành từ 
phía độc giả.

notboth.Acapital budgetingdecision between twodifferentstampingmachines with 
different costsandoutput would beanexample ofchoosing between twomutually 
exclusiveprojects. 
Project Sequencing 
Someprojectsmust beundertakeninacertain order,orsequence, sothat investing in aproject 
today createstheopportunitytoinvest inother projects inthefuture. For example, if a project 
undertakentoday is profitable, that maycreate the opportunity to invest in a second project a 
year from now. However, if the project undertakentoday turns out to be unprofitable, the 
firm willnot investinthesecond project. 
UnlimitedFunds vs.Capital R a t i o n i n g

Apositive NPV project isexpected toincrease shareholder wealth, anegative NPV project 
isexpected todecreaseshareholder wealth, and azeroNPV project hasno expected 
effectonshareholder wealth. 
Forindependent projects, theNPV decisionruleissimply toaccept anyproject with a positive 
NPV andtorejectanyproject with anegative NPV. 
Example: NPV analysis 
Using the project cash flows presented Table 1, compute the NPV of each project’s cash 
flows and determine for each project whether it should be accepted or rejected. Assume that 
the cost of capital is 10%.

Answer: 
Both Project A and Project B have positive NPVs, so both should be accepted.

return on the market, and the expected returns at Point A and Care greater and less than the 
expected return on the market (tangency) portfolio, respectively. 
Note that a low-beta stock, such as represented by Point C, is not necessarily low-risk when 
total risk is considered. While its contribution to the risk of a well-diversified portfolio may 
be low, its risk when held by itself can be considered quite high. A firm whose only activity is 
developing a new, but as yet unproven, drug may be quite speculative with highly uncertain 
returns. It may also have quite low systematic risk if the uncertainty about itsfuture returns 
depends primarily on firm-specific factors. 
All stocks and portfolios that plot along the line labeled β = 1 in Figure 9 have the same 
expected return as the market portfolio and, thus, according to the CAPM, have the same 
systematic risk as the market portfolio (i.e., they all have betas of one). 
All points on the CML (except the tangency point) represent the risk-return characteristics 
of portfolios formed by either combining the market portfolio with the risk-
freeassetorborrowing attherisk-freerateinordertoinvestmorethan 100%of theportfolio's

According totheCAPM, allsecuritiesandportfolios, d iv e r s i f i ed ornot,willplotontheSMLin

Example: Identifying mispriced securities 
The following figure contains information based on analyst’s forecasts for three stocks. 
Assume a risk-free rate of 7% and a market return of 15%. Compute the expected and 
required return on each stock, determine whether each stock is undervalued, overvalued, 
or properly valued, and outline an appropriate trading strategy.

• Stock A is overvalued. It is expected to earn 12%, but based on its systematic risk, 
it should earn 15%. It plots below the SML.

 Chủ đề 4: Portfolio Management

• Stock B is undervalued. It is expected to earn 17.5%, but based on its systematic 
risk, it should earn 13.4%. It plots above the SML. 
• Stock C is properly valued. It is expected to earn 16.6%, and based on its 
systematic risk, it should earn 16.6%. It plots on the SML. 
The appropriate trading strategy is: 
• Short sell Stock A. 
• Buy Stock B. 
• Buy, sell, or ignore Stock C. 
We can do this same analysis graphically. The expected return/beta combinations of all 
three stocks are graphed in the following figure relative to the SML. 
Identifying Mispriced Securities 
Remember, allstocks should plot on the SML; anystock not plotting on the SML is mispriced. 
Notice that Stock A falls below the SML, Stock B lies above the SML, and Stock C is on the 
SML. If you plot a stock’s expectedreturn and it falls below the SML, the stock is 
overpriced. That is, the stock's expected return is too low given itssystematic risk. If a stock 
plots above the SML, it is underpriced and is offering an expected return greater than 
required for its systematic risk. If it plots on the SML, the stock is properly priced.

Because the equation of the SML is thecapital assetpricing model, you can determine if a 
stock is over- or underpriced graphically or mathematically. Your answers willalways be 
the same. 
When we evaluate the performance of a portfolio with risk that differs from that of a 
benchmark, we need to adjust the portfolio returns for the risk of the portfolio. There 
are several measures of risk-adjusted returns that are used to evaluate relative portfolio 
One such measure is the Sharpe ratio 
The Sharpe ratio of a portfolio is its excess returns per unit of total portfolio risk, and 
higher Sharpe ratios indicate better risk-adjusted portfolio performance. Note that this 
is a slope measure and, as illustrated in Figure 9, the Sharpe ratios of all portfolios 
along the CML are the same. Because the Sharpe ratio uses total risk, rather than 
systematic risk, it accounts for any unsystematic risk that the portfolio manager has taken. 
Note that the value of the Sharpe ratiois only useful for comparison with the Sharpe ratio of 
another portfolio. 
In Figure 10, we illustrate that the Sharpe ratio is the slope of the CAL for the portfolio 
and can be compared to the slope of the CML, which is the Sharpe ratio for any portfolio 
along the CML.

~--~ 
The M-squared (M2) measure produces the same portfolio rankings as the Sharpe ratiobut is 
stated in percentage terms. It is calculated as 
The intuition of this measure is that the first term is the excess return on a Portfolio P*, 
constructed by taking a leveraged position in Portfolio P so that P* has the same total 
risk, M, as the market portfolio. As shown in Figure 11, the excess return on such a 
leveraged portfolio is greater than the return on the market portfolio by the vertical 
distance M2. 
Figure 11: M-squared for a Portfolio 
Two measures of risk-adjusted returns based on systematic risk (beta) rather than totalrisk 
are theTreynor measure and Jensen's alpha. They are similar to the Sharpe ratio and M2 in 
that the Treynor measure is based on slope and Jensen's alpha is a measure of percentage 
returns in excess of those from a portfolio that has the same beta but lies on the SML. 
The Treynor measure is calculated as , interpreted as excess returns per unit of 
systematic risk, and represented by the slope of a line as illustrated in Figure 12. 
Jensen's alpha for Portfolio Pi calculated as = R - [Rf + βp(RM - Rf)] and is the 
percentage portfolio return above that of a portfolio (or security) with the same beta as 
the portfolio that lies on the SML, as illustrated in Figure 12.

Figure 12: Treynor Measure and Jensen’s Alpha 
Whether risk adjustment should be based on total risk or systematic risk depends on 
whether a fund bears the nonsystematic risk of a manager's portfolio. If a single manager 
is used, then the total risk (including any nonsystematic risk) is the relevant measure 
and risk adjustment using total risk, as with the Sharpe and M2 measures, is appropriate. If 
a fund usesmultiple managers so that the overall fund portfolio is well diversified (has no 
nonsystematic risk), then performance measures based on systematic (beta) risk, such as the 
Treynor measure and Jensen's alpha, are appropriate. 
These measures of risk-adjusted returns areoften used to compare theperformance of actively 
managed funds to passively managed funds. Note in Figures 10 and 11 that portfolios that lie 
above the CML have Sharpe ratios greater than those of any portfolios along the CML and 
have positive M2 measures. Similarly, in Figure 12, we can see that portfolios that lie above 
the SML have Treynor measures greater than those of any security or portfolio that lies along 
the SML and also have positive values for Jensen's alpha. 
One final note of caution isthat estimating the values needed to apply these theoretical models 
and performance measures is often difficult and is done with error. The expected return on the 
market, and thus the market risk premium, may not be equal to its average historical value. 
Estimating security and portfolio betas is done with error as well.
