Active 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

Investment 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)

– Passive asset class funds capture separate dimensions

of worldwide returns

Passive versus Active Portfolio

Management

• Review of Market Efficiency

• Anomalies

• Market Timing

• A theoretical model of active portfolio

management (Treynor-Black)

• Quantitative Investment Management

Trang 10

Passive Management

• Buy and Hold

• Indexation

• Active management must beat these

strategies on a net risk adjusted return basis!

• What if markets are efficient?

Trang 11

Treynor-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 12

Treynor-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 13

Treynor-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 14

Treynor-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‘)
