Chapter 18: Equity Portfolio Management Strategies Passive Management Strategies

When an investor's primary objective is to capture the broad return of an asset class (e.g., the overall equity market) without taking additional risk to generate alpha, passive management is the appropriate choice.

Benefits of Passive Portfolio Management

Lower cost of managing the portfolio
Low dependence on fund manager's individual skill or judgment
Better, more predictable risk profile
Benchmarks are generally well-diversified

Buy and Hold Strategy

The investor selects a stock or portfolio of stocks and holds them over a very long time — without making frequent changes. No active decision-making after initial purchase.

Indexing

The portfolio manager creates a portfolio that mirrors a specific index. The goal is to replicate the index's performance as closely as possible. Sub-types:

Full Replication: All securities in the index are held in the same (or very close) weightings as the index. Minimizes tracking error but can be expensive for large indices.
Sampling: A representative subset of the index is held (used when full replication is impractical due to cost or liquidity).

Active Management Strategies

Active managers believe they can identify mispricings in the market and exploit them to generate alpha (returns above the benchmark).

Market Timing

Active strategy based on predicting broad market direction. A manager forecasting a rising market would:

Shift funds from cash to stocks, OR
Increase the beta of the equity portfolio

Sector Rotation

Shifting investments from one sector to another based on expected sectoral outperformance or underperformance. Implemented by increasing or reducing sector weights in the portfolio relative to the benchmark.

The Fundamental Law of Active Management

This law predicts a manager's ability to add value (ex-ante) based on two variables:

Skill: Measured by Information Coefficient (IC) — the correlation between the manager's return forecasts and actual returns. Higher IC = more accurate forecasts.
Breadth: The number of independent investment decisions (bets) made using that skill.

Information Ratio (IR) = IC × √Breadth

A manager with high skill AND a large number of independent bets adds the most value.

Smart Beta Management Strategies

Smart Beta lies between purely passive index mirroring and fully discretionary active management. It uses rules-based index construction but applies factors or criteria selected by the manager — making it partly active in nature.

Key Attributes of Smart Beta

Rule-based index construction (like passive)
Alternative index strategies based on factors like quality, value, volatility, size, or momentum (like active)

Factor-Based Portfolios

Portfolio managers identify specific factors that drive stock returns and create rule-based portfolios around them. Common equity factors include:

Factor	Description
Value	Low-priced stocks relative to fundamental metrics (low PE, low PB)
Size	Small-cap stocks tend to outperform large-cap over time
Momentum	Stocks that have recently risen tend to continue rising
Quality	High-quality companies with strong balance sheets and earnings stability
Low Volatility	Low-risk stocks that deliver superior risk-adjusted returns

Uses of Factor Models

Portfolio construction (creating the initial portfolio)
Attribution analysis (explaining sources of return)
Risk analysis (understanding risk exposures)
New product development decisions

Investment Management Styles

Growth Investing: Buying stocks with high earnings growth potential, expecting them to outperform the market as growth materializes.
Value Investing: Buying undervalued stocks (trading below intrinsic value) and profiting when the market corrects the mispricing.
Blended Portfolio: Combines both growth and value stocks — a hybrid approach offering diversification across investing styles.

Socially Responsible Investing (SRI) / ESG Investing

An emerging approach where investment decisions are based on ESG criteria:

E – Environmental (climate impact, resource usage)
S – Social (employee welfare, community impact)
G – Governance (board composition, transparency, executive pay)

Also known as green investing or ethical investing. Increasingly demanded by institutional and retail investors who want their portfolios aligned with their values.

Core and Satellite Investment Approach

The portfolio consists of two parts:

Core Portfolio: Large portion; managed passively; reflects the long-term risk profile of the investor; cost-efficient.
Satellite Portfolio(s): Smaller portions; actively managed; designed to capitalize on short-term opportunities and generate additional alpha.

Alpha-Beta Separation

Portfolio returns can be decomposed into:

Beta return: Return from exposure to market (systematic) risk — passively generated
Alpha return: Return from non-market (idiosyncratic) risk — requires active management skill

Using sophisticated strategies, it is possible to separately manage the alpha and beta components of a portfolio.

Using Derivatives in Equity Portfolio Management

Derivatives are used in equity portfolios to address two main challenges:

Price Risk: Risk of falling prices reducing portfolio value
Volatility Risk: Portfolio risk exceeding the investor's or mandate's tolerance

Derivatives applications include: Generating Alpha, Hedging existing positions, and Arbitrage opportunities.

Global Active Strategy

Diversifying a domestic portfolio globally reduces country-specific risk. However, investors tend to exhibit home bias — a tendency to over-invest in domestic markets due to familiarity advantage (knowledge of local businesses, regulations, and consumer behavior).

Chapter 19: Fixed Income Portfolio Management Strategies Why Investors Prefer Fixed Income

Fixed income instruments provide more predictable returns compared to equity. They are particularly attractive to investors who need to match known future liabilities (like pension funds, insurance companies) or who prefer stable income over growth.

Passive Fixed Income Strategies 1. Buy and Hold

Buy securities and hold them until maturity. The primary objective is to lock in the current yield, irrespective of price fluctuations. A portfolio of bonds can also be created with each security held to its own maturity date.

2. Bond Index Funds (Indexing)

Creating a portfolio that holds the same (or similar) securities as a bond benchmark in the same proportions. The portfolio manager's role is purely to track the benchmark closely. Reasons to use bond index funds:

Portfolio Mandate requirements
Lower Management Fees
Ease of Replication
Wide Availability of Choice
Liquidity Risk Mitigation

Tracking Error in Passive Management

Tracking error is the standard deviation of the difference between portfolio returns and benchmark returns. Lower tracking error is better. Common causes of tracking error:

Transaction costs
Similar but not identical securities being held
Weight differences vs. benchmark
Illiquid securities that can't be replicated
Regulatory constraints on concentration
Cash holdings in the portfolio

3. Immunization

Immunization is a passive strategy designed to protect a fixed income portfolio from interest rate risk and reinvestment risk. It ensures the portfolio's terminal value meets a future liability regardless of interest rate movements.

Two methods:

Zero-Coupon Bond Match: Invest in a zero-coupon bond with maturity matching the liability date — the simplest form of immunization.
Duration Matching: Create a portfolio of bonds whose weighted-average Macaulay Duration equals the liability time horizon.

Active Fixed Income Strategies

Active managers take views on future interest rates, yield spreads, or credit quality and adjust the portfolio to maximize returns.

Interest Rate Driven Strategies

Directional Call: When the portfolio manager anticipates interest rates will fall (meaning bond prices will rise), they increase portfolio duration to benefit from price appreciation. If rates expected to rise, duration is reduced.
Barbell Strategy: Portfolio is concentrated at both short and long ends of the duration spectrum with minimal mid-duration bonds. Used when there is high uncertainty about the direction of rates.
Bullet Strategy: Portfolio concentrated at a single maturity/duration point. Used when the manager has a clear view on interest rate movement.
Floaters: Bonds whose coupon resets periodically with an underlying benchmark rate. Provide protection against large interest rate moves.
Maturity Extension: Buying long-dated bonds in a stable, low interest rate environment to capture higher yields along the yield curve.
Roll Down Strategy: In an upward-sloping yield curve, as time passes, a bond's remaining maturity decreases, and its yield declines — leading to price appreciation. The portfolio captures both coupon income and this price gain.
Buying Convexity: For large changes in yields, the price-yield relationship is not linear. Convexity (a second-order effect) means bonds with higher convexity gain more when yields fall and lose less when yields rise. Managers may seek higher-convexity bonds for better risk management.

Credit Analysis and Credit Strategies

Corporate bonds carry default risk. Credit rating agencies evaluate financial health and assign ratings.
Put Option Embedded Bonds: Give the bondholder the right to sell the bond back to the issuer at a specified price — provides downside protection.

Types of Credit Fund Management

Optimizing Yield and Credit Quality — balancing return enhancement vs. risk
High Yield / Junk Corporate Bonds — targeting higher yields from below-investment-grade issuers

Global Fixed Income Strategy

Portfolio managers can exploit global fixed income opportunities such as:

Relative Value: Buy undervalued bonds in one country, short overvalued bonds in another
Illiquidity Premium: Capture extra return by investing in less liquid bonds globally

Risks in global fixed income investing: Economy Risk, Legal Risk, Currency Risk.

Bond Portfolio Protection with Derivatives

Fixed income derivative instruments used for risk management:

Interest Rate Swaps
Futures (on bonds/interest rates)
Forward Contracts
Credit Default Swaps (CDS)
Currency Swaps

Fixed Income Portfolio Risk Management

Portfolio managers decide which risks to hedge and which to accept — particularly important when performance is judged on a relative (benchmark) basis. Key applications:

Managing Interest Rate Risks (duration management)
Protective Puts (on bond positions)
Managing Assets and Liabilities (ALM framework)
