Why a second edition? Why take time from busy lives? Why devote the energy to improving an existing text rather than writing an entirely new one? Why toy with success?
The short answer is: our readers. We have been extremely gratified by Active Portfolio
Management's reception in the investment community. The book seems to be on the shelf of every practicing or aspiring quantitatively oriented investment manager, and the shelves of many fundamental portfolio managers as well.
But while our readers have clearly valued the book, they have also challenged us to improve it.
Cover more topics of relevance to today. Add empirical evidence where appropriate. Clarify some discussions. The long answer is that we have tried to improve Active Portfolio Management along exactly these dimensions. First, we have added significant amounts of new material in the second edition. New chapters cover
Advanced Forecasting (Chap. 11), The Information Horizon (Chap. 13), Long/Short Investing
(Chap. 15), Asset Allocation (Chap. 18), The Historical Record for Active Management (Chap. 20), and Open Questions (Chap. 21).
Some previously existing chapters also cover new material. This includes a more detailed discussion of risk (Chap. 3), dispersion (Chap. 14), market impact (Chap. 16), and academic proposals for performance analysis (Chap. 17).
Second, we receive exhortations to add more empirical evidence, where appropriate. At the most general level: how do we know this entire methodology works? Chapter 20, on The Historical
Record for Active Management, provides some answers. We have also added empirical evidence about the accuracy of risk models, in Chap. 3.
At the more detailed level, readers have wanted more information on typical numbers for information ratios and active risk. Chapter 5 now includes empirical distributions of these statistics.
Chapter 15 provides…...

Active Portfolio Management Strategy

...Definition: In an active portfolio strategy, a manager uses financial and economic indicators along with various other tools to forecast the market and achieve higher gains than a buy-and-hold (passive) portfolio. Tracking error is a measure of how closely a portfolio follows the index to which it is benchmarked. The most common measure is the root-mean-square of the difference between the portfolio and index returns. Many portfolios are managed to a benchmark, normally an index. Some portfolios are expected to replicate, before trading and other costs, the returns of an index exactly (an index fund), while others are expected to 'actively manage' the portfolio by deviating slightly from the index in order to generate active returns or to lower transaction costs. Tracking error (also called active risk) is a measure of the deviation from the benchmark; the aforementioned index fund would have a tracking error close to zero, while an actively managed portfolio would normally have a higher tracking error. Dividing portfolio active return by portfolio tracking error gives the information ratio, which is a risk adjusted performance metric. If tracking error is measured historically, it is called 'realised' or 'ex post' tracking error. If a model is used to predict tracking error, it is called 'ex ante' tracking error. The former is more useful for reporting performance, whereas ex ante is generally used by portfolio managers to control risk. The individual investors who......

Style Drift and Portfolio Management for Active

...Drift and Portfolio Management for Active Australian Equity Funds † Andrew B. Ainsworth ∗ Kingsley Fong David R. Gallagher Current Draft: 30 April 2007 Australian School of Business, The University of New South Wales, Sydney, N.S.W. 2052 Abstract Using monthly active equity fund portfolio holdings, we examine the magnitude of style drift and decompose it into active and passive components. We find that while fund style tilts are consistent with their self-stated investment objective, there is variation in the degree of style bias within style groups. We document that funds actively adjust their portfolio holdings in response to passive style drift to retain a desired portfolio tilt. The degree of adjustment varies with the frequency over which the drift is measured, with funds being most responsive to changes in book-to-market and momentum drift. We also find that certain types of style drift affect portfolio turnover. Keywords: Investment style, style drift, consistency, portfolio management, investment performance. † This research was funded through an ARC Linkage Grant (LP0561160) involving Vanguard Investments Australia and SIRCA.

Active Portfolio Management: Country vs. Sector Characteristics

...Active Portfolio Management: Country vs. Sector Characteristics Executive Summary This project sets out to invest between 7bn and 9bn Euros for a large pension fund in European equities, chosen from the MSCI Europe Index, which also serves as the benchmark to measure performance against. Two portfolios need to be created, one to reflect asset allocation focussed on countries and the other on sectors, with the number of assets in each portfolio being no more than 150. Both portfolios must be actively managed, having at least an active risk of 3% when compared to the benchmark. To achieve this, I followed a three step top-down approach for our investment decision process. Firstly, I started with an analysis of the macroeconomic environment in Europe, followed by forming opinions on the relative strengths and weaknesses of the constituent countries and sectors, using the macro-analysis to determine which are most likely to perform well, given the long-run trends identified. Finally, I invested in all mid-cap companies within the selected countries and sectors, based on our judgement that middle sized firms are poised to prosper the most in this difficult economic environment, which I predict to remain tough for the foreseeable future. After finalising the initial portfolios in this way, I used BarraOne to optimise them. Following optimisation, I compared the risk profile of each portfolio to the benchmark. Our findings show that an actively managed portfolio, especially one......

Portfolio Evaluation

...expected return to fund the sudden increase in pension liability. 2) Critically assess the benefits of adding equities to the existing bond-only portfolio The pension fund can benefit from adding equities to its existing bond-only portfolio in many ways. According to the portfolio theory, by investing in as little as 20 shares can result in a well-diversified portfolio where unsystematic risk is largely diversified away (Statman, 3 1987). This will only leave systematic risk or undiversifiable risks to content with as seen below: The pension fund could thus possibly earn higher rewards but by taking lower risks if they are able to invest in a well-diversified stock portfolio, potentially an index tracker. Adding equities to a bond-only portfolio also has theoretically sound benefits as well. As the pension fund already holds treasury and corporate bonds, and based on the Modern Portfolio Theory, the fund could possibly result in an investment portfolio made up of stocks that sit on the efficient frontier and a risk-free asset (Markowitz, 1991). This risk free asset could be a government bond. This combination could result in returns in excess of the efficient frontier portfolios (Merton, 1973). However, there are a few issues with the considerations that are involved in adding equities to a bond only portfolio. There are no guarantees that equities will generate higher return than bonds, even over a long-term investment period. For example, from......

ERIK KNUTZEN ERIK K NUTZEN is the chief investment officer at NEPC LLC in Cambridge, MA. eknutzen@nepc.com FALL 2013 JOI-KNUTZEN.indd 75 I n the past several years, asset managers have built investment strategies based on historical evidence that lower volatility stocks earn superior risk-adjusted returns. These approaches are being called low volatility, managed volatility, minimum variance, or similar names. They seek to exploit what has been identified in studies by academics and practitioners alike as an equity pricing anomaly. This anomaly joins previously identified persistent stock market inefficiencies associated with low price-tobook and smaller company shares. This article evaluates the low volatility anomaly, its potential causes, whether it is likely to persist, and the role, if any, of low volatility equity investing in long-term investment programs. Based on historical information, we conclude that the low volatility equity anomaly appears to exist and can be explained by certain behavioral and structural biases of investors. But its continued existence into the future is less certain. We also observe that even well-documented anomalies experience......

Portfolio Strategies

... Portfolio Strategy Assignment Demetrie M. Howard University of Phoenix Introduction The organization I have chosen to plan a portfolio strategy for is O’Connor and Associates. This organization is my current employer and it will be a challenge to create one for them. The organization is a property tax firm, it assist clients with reducing the appraised value of their property, which in turn reduces the amount of property taxes due. The organization is diversifying; it is going into third party collections, judgment recovery, and mortgage loans. This firm has made substantial errors in the past therefore to understand the cause and effect of those errors we will attempt to model their market and business behaviour. This model is an effort to estimate the expected results of alternative strategies and processes. Consumer expectations and other variables as well as technology, the internet, telecommunications and globalization have accelerated the pace of change, and shortened product lifecycles has contributed to this strategic plan.

Active management is whereby financial professionals try to outperform a specific benchmark. Passive funds like the exchange traded funds (ETFs) are whereby the index is tracked with no active stock selection (Barr, 2009). The risk of a failing a benchmark or index can be reduced through passive investment. Passive investment also reduces the cost. The active investment has the potential of boosting returns through outperforming some benchmarks. However, there are increased risks and also there are no guarantees that the benchmarks will be exceeded or matched. In a well-diversified portfolio, active and passive investment can flourish. The role of ETFs which is an important building block for dynamic and diverse portfolios is to offer access to equities and fixed income across large developed economies and the emerging markets. ETFs can be traded like share, thus similar liquidity is offered hence it allows the investor to adjust to their portfolios. In the context of investors’ specific objective, active management allows risks to be managed properly (Barr, 2009).

Eight Threats

...8 Threats to Portfolio Performance The last decade has been a challenge for many investors, especially those investing for the long term and retirement. Given declines in global stock markets, many investors have seen little to no real growth in their portfolios over this period. For example, $10,000 invested in the S&P 500 Market Index in 2000, was worth just $10,456 at the end of 2010. And this does not take into account inflation, investment fees and taxes.1 This White Paper explains why investors’ portfolios may underperform in both bear and bull markets and incur substantial costs in the process. It also details the impact this chronic underperformance can have on achieving long-term financial goals. Threat 1: The Expenses of Active Management Most us would like to beat the market, but as we’ll explore in this whitepaper, even many professional money managers have had a hard time performing better than the market. To understand why, it is helpful to begin with some definitions. Active investors (and active money managers) attempt to out- perform stock market rates of return by actively trading individual stocks and/or engaging in market timing — deciding when to be in and out of the market. Those investors who simply purchase “the market” through index or asset class mutual funds are called passive or “market” investors. Active mutual fund managers are typically compared to a benchmark index. For example, large cap mutual funds are often compared to the...

The Sharpe Ratio and the Information Ratio

...Ratio used to determine the risk-adjusted return of an investment portfolio. Sharpe Ratio The Sharpe Ratio introduced a method of assessing manager performance relative to risk taken. Sharpe Ratio centres on the use of a RFR, this places all mangers on a level playing field regardless of style. (Expected Portfolio Return – RFR) / Portfolio Standard Deviation Hypothetically, investors should always be able to invest government bonds and obtain the RFR. The sharpe ratio determines the expected realized return over that minimum. Within the risk-reward framework of portfolio theory, higher risk investment should produce high returns. As a result, a high Sharpe ratio indicates superior risk adjusted performance. Sharpe ratio measures a portfolio’s added value relative to its total risk. (A portfolio of risk free assets or one with an excess return of zero would have a Sharpe ratio of zero.) Sharpe ratio was based on portfolio theory, it is designed to be applied to investment strategies that have normal expected return distributions, it is not suitable for measuring investments that are expected to have asymmetric returns. Information Ratio (Portfolio Return – Benchmark Return) / Tracking Error or Active Return/Active Risk (Portfolio Return – Benchmark Return) referred to as the active return. The IR uses the SD of active returns as a measure of risk instead of the SD of the portfolio. It measures the manager’s excess return over an appropriate......

Should Retail Investors Invest in Index-Tracker Funds Rather Than Actively-Managed Funds?

...which aims to achieve the same level of returns of following the returns , and catch up the market growth at the same time. The index fund is a kind of passive management fund which is just opposite to the actively management fund. There are many characteristics of index fund. 1, Index Investing uses passive operation of tracking the benchmark index, which can make the costs of the fund's operating and transaction into a minimum. Portfolio strategy can be adjusted by According to the change of the index’s Composition, and what’s more, no fees will be paid about the investment research and analysis. So a lower management fee will be charged. On the other hand, the index investors tend to buy long-term holders of stocks, as opposed to active management by actively trading the formation of high turnover and must pay higher transaction costs, the investment of index funds does not take any adjustment to the investment portfolio initiatively, and the low cost of turnover transaction will be paid. These are quite different while compared with the actively managed fund. 2, The index fund has a high utilization of its money. All the investments of index funds are used to track the benchmark index, and it has no cash drag problems. But the traditional open-end fund with actively management will keep 5% -10% of cash in the portfolio at least to prepare for redemption.

...Back to the Drawing Board Investors are having to rethink the foundations on which they build their portfolios By  JOHN FERRY AND MIKE FOSTER Updated April 12, 2010 12:01 a.m. ET The recent financial crisis has all but torn up the investment rule book—received wisdoms have been found wanting if not plain wrong. Investors are being forced to decide whether the theoretical foundations upon which their portfolios are constructed need to be repaired or abandoned. Some are questioning the wisdom of investing in public markets at all. ENLARGE ROBERT NEUBECKER Many professional investors have traditionally used a technique known as modern portfolio theory to help decide which assets they should put money in. This approach examines the past returns and volatility of various asset classes and also looks at their correlation—how they perform in relation to each other. From these numbers wealth managers calculate the optimum percentage of a portfolio that should be invested in each asset class to achieve an expected rate of return for a given level of risk. It is a relatively neat construct. But it has its problems. One is that past figures for risk, return and correlation are not always a good guide to the future. In fact, they may be downright misleading. "These aren't natural sciences we're dealing with," says Kevin Gardiner, head of investment strategy for Europe, the Middle East and Africa at Barclays Wealth in London. "It's very difficult to establish underlying models......
