Trang 5Active Management
– The process of managing investment portfolios by
attempting to time the market and/or select
“undervalued” stocks to buy and “overvalued” stocks to sell based upon company research, investigation and
analysis
Passive Management
– The process of managing investment portfolios by trying
to match the performance of an index or asset class of
securities as closely as possible by holding all or a
representative sample of the securities in the index or
asset class
– Does not use market timing or stock selection strategies

Trang 6Investment Decision Matrix:
Where Do You Fit In?
Market Timers and Stock Selectors *
Where the common crowd hangs out Preference of active management, high-cost “gurus * ”
Heavy on investment hype
Stock Selectors Preference of stockbrokers and many financial advisors *
High cost, high turnover, high taxes
Market Timers
Tactical analysis * (with no proven results)
Tax inefficient
Short-term outlook
The Informed Investor
Based on academic research and data *
As much as 40% of institutional invested dollars The prudent investors
Receive market returns Where YOU should be (and where we are)
Trang 7• Asset Class Investing
– Stocks and Bonds
– US and International
– Large Cap and Small Cap
– Growth and Value
– Short-Term and Long-Term Maturity
Trang 8• Why Use Passive Asset Class Investing?
– Lower portfolio turnover
– Lower operating expenses
– Lower transaction costs
– Greater tax-efficiency
– Long-term perspective
– Broad diversification/risk reduction
– Control of asset allocation
– Passive asset class funds capture separate dimensions
of worldwide returns
Trang 9Passive versus Active Portfolio
Management
• Review of Market Efficiency
• Anomalies
• Market Timing
• A theoretical model of active portfolio
management (Treynor-Black)
• Quantitative Investment Management
Trang 10Passive Management
• Buy and Hold
• Indexation
• Active management must beat these
strategies on a net risk adjusted return basis!
• What if markets are efficient?
Trang 11Treynor-Black Model
• Suppose you can identify securities that you expect to outperform (or underperform) on a risk-adjusted basis
• How do you exploit this model?
Trang 12Treynor-Black Model: Assumptions
• Analysts can only produce quality analysis on a small number of securities
• There is a passive market portfolio (M)
securities
• Find optimal weights of analyzed securities to create active component (A)
• Combine A, M and risk-free asset to achieve
Trang 13Treynor-Black: Construction (Step 1)
• Assume: ri = rf + bi(rM - rf) + ei
• For analyzed security k:
rk = rf + bk(rM - rf) + ek + ak
=> estimate ak, bk, s2(ek)
• To construct A:
wk = ( ak/ s2(ek))/( S[ai/ s2(ei)])
=> determine aA, bA, s2(eA)
Trang 14Treynor-Black: Construction (Step 2)
• w0 = ( aA/ s2(eA))/[(E(rM)-rf)/ s2
M]
• w* = w0/(1+(1- bA)w0)
• w0 is the proportion of A in the new, enhanced market portfolio (M‘)
