A portfolio manager is a person or group of people responsible for investing a mutual, exchange traded or closed-end fund's assets, implementing its investment strategy, and managing day-to-day portfolio trading. A portfolio manager is one of the most important factors to consider when looking at fund investing. Portfolio management can be active or passive, and historical performance records indicate that only a minority of active fund managers consistently beat the market.

Definition

A portfolio manager is an individual or group responsible for managing the assets of investment funds such as mutual funds, ETFs, or closed-end funds. They implement investment strategies and manage daily portfolio trading. Portfolio managers are a crucial factor in fund investment. Portfolio management can be active or passive, with historical data showing that only a few active managers consistently outperform the market.

Origin

The concept of portfolio management originated in the early 20th century as financial markets became more complex and investment products diversified. The development of modern portfolio theory in the 1950s further advanced this field.

Categories and Features

Portfolio management is divided into active and passive management. Active management involves fund managers actively selecting investments to outperform the market, while passive management typically tracks market indices. The advantage of active management is the potential for high returns, but it comes with higher risks and fees; passive management is known for its low cost and stability.

Case Studies

A classic example is Peter Lynch, who managed the Fidelity Magellan Fund from 1977 to 1990, achieving an average annual return of 29%. Another example is Warren Buffett, who successfully implemented a long-term investment strategy through Berkshire Hathaway, becoming one of the world's most successful investors.

Common Issues

Investors often misunderstand that active management always leads to higher returns, but many active funds fail to consistently outperform the market. Additionally, investors should be aware of the impact of management fees on long-term returns.

Technical Indicator

Technical indicators are heuristic or pattern-based signals produced by the price, volume, and/or open interest of a security or contract used by traders who follow technical analysis.By analyzing historical data, technical analysts use indicators to predict future price movements. Examples of common technical indicators include the Relative Strength Index (RSI), Money Flow Index (MFI), stochastics, moving average convergence divergence (MACD), and Bollinger Bands.

Technical Analysis

Technical analysis is a trading discipline employed to evaluate investments and identify trading opportunities by analyzing statistical trends gathered from trading activity, such as price movement and volume. Unlike fundamental analysis, which attempts to evaluate a security's value based on business results such as sales and earnings, technical analysis focuses on the study of price and volume.

Basis Risk

Basis Risk refers to the risk that arises when there is a difference between the spot price of an asset and the futures price of that asset (known as the basis) during hedging with financial derivatives. Specifically, when investors or businesses use futures contracts to hedge against price fluctuations in the spot market, if the changes in the spot price and the futures price do not move in perfect correlation, the hedging may be less effective, leading to potential losses. For instance, a farmer uses wheat futures to hedge against the risk of a decline in crop prices, but if the difference between the spot price and the futures price of wheat at the time of contract expiration is greater than expected, this change in basis represents the basis risk. Basis risk is common in commodity markets, foreign exchange markets, and interest rate markets.

Opportunity Cost

Opportunity costs represent the potential benefits that an individual, investor, or business misses out on when choosing one alternative over another. Because opportunity costs are unseen by definition, they can be easily overlooked. Understanding the potential missed opportunities when a business or individual chooses one investment over another allows for better decision making.

Hurdle Rate

The Hurdle Rate, also known as the Minimum Acceptable Rate of Return (MARR) or Required Rate of Return (RRR), is the minimum rate of return on an investment project that a company or investor is willing to accept before proceeding with the investment. This rate is set by the company's management or investors and serves as a benchmark for evaluating the feasibility of investment projects. The hurdle rate takes into account the cost of capital, risk premium, and other factors to ensure that the investment yields sufficient returns to compensate for the risks involved. If the expected return on a project is below the hurdle rate, the project is typically rejected. The hurdle rate is crucial in capital budgeting and project evaluation, aiding companies in effective resource allocation and risk management.

Horizontal Spread

A Horizontal Spread, also known as a Time Spread or Calendar Spread, is an options trading strategy. This strategy involves simultaneously buying and selling options contracts with the same strike price but different expiration dates. Typically, a trader will buy a long-term option and sell a short-term option. The goal of a horizontal spread is to profit from the difference in time value, especially when the underlying asset's price is not expected to move significantly. By employing this strategy, traders can benefit from the different rates of time decay (the reduction in the value of an option as it approaches its expiration date). Horizontal spreads are suitable for investors who have an expectation of market volatility but are uncertain about the specific direction of the price movement.
