What Is a Portfolio?

A portfolio is a collection of financial investments like stocks, bonds, commodities, cash, and cash equivalents, including closed-end funds and exchange-traded funds (ETFs). People generally believe that stocks, bonds, and cash comprise the core of a portfolio. Though this is often the case, it does not need to be the rule. A portfolio may contain a wide range of assets including real estate, art, and private investments.

You may choose to hold and manage your portfolio yourself, or you may allow a money manager, financial advisor, or another finance professional to manage your portfolio.

Understanding Portfolios

One of the key concepts in portfolio management is the wisdom of diversification鈥攚hich simply means聽not to put all your eggs in one basket. Diversification tries to reduce聽risk聽by allocating investments among various financial instruments, industries, and other categories. It aims to maximize returns聽by investing in different areas that would each react differently to the same event. There are many ways to diversify. How you choose to do it is up to you. Your goals for the future, your appetite for risk, and your personality are all factors in deciding how to build your portfolio.

Regardless of your portfolio's asset mix, all portfolios should contain some degree of diversification, and reflect the investor's tolerance for risk, return objectives, time horizon, and other pertinent constraints, including tax position, liquidity needs, legal situations, and unique circumstances.

Managing a Portfolio

You may think of an investment portfolio as a pie that's been divided into pieces of varying wedge-shaped sizes, each piece representing a different asset class and/or type of investment. Investors aim to construct a well-diversified portfolio to achieve a risk-return portfolio allocation that is appropriate for their level of risk tolerance. Although stocks, bonds, and cash are generally viewed as a portfolio's core building blocks, you may grow a portfolio with many different types of assets鈥攊ncluding real estate, gold stocks, various types of bonds, paintings, and other art collectibles.

50% bonds, 20% stocks, and 30% short-term investments provide an example of a conservative investment portfolio.

The sample portfolio allocation pictured above is for an investor with a low tolerance for risk. In general, a conservative strategy tries to protect a portfolio's value by investing in lower-risk securities. In the example, you'll see that a full 50% is allocated to bonds, which might contain high-grade corporates and government bonds, including municipals (munis). The 20% stock allocation could comprise blue-chip or large-cap equities, and 30% of short-term investments might include cash, certificates of deposit (CDs), and high-yield savings accounts.

Most investment professionals agree that, though it does not guarantee against loss, diversification is a key component for reaching long-range financial goals while minimizing risk.

Types of Portfolios

There can be as many different types of portfolios and portfolio strategies as there are investors and money managers. You also may choose to have multiple portfolios, whose contents could reflect a different strategy or investment scenario, structured for a different need.

A Hybrid Portfolio

The hybrid portfolio approach diversifies across asset classes. Building a hybrid portfolio requires taking positions in stocks as well as bonds, commodities, real estate, and even art. Generally, a hybrid portfolio entails relatively fixed proportions of stocks, bonds, and alternative investments. This is beneficial, because historically, stocks, bonds, and alternatives have exhibited less than perfect correlations with one another.

A Portfolio Investment

When you use a portfolio for investment purposes, you expect that the stock, bond, or another financial asset will earn a return or grow in value over time, or both.聽A portfolio investment may be either strategic鈥攚here you buy financial assets with the intention of holding onto those assets for a long time; or tactical鈥攚here you actively buy and sell the asset hoping to achieve short-term gains.

An Aggressive, Equities-Focused Portfolio

The underlying assets in an aggressive portfolio generally would assume great risks in search of great returns. Aggressive investors seek out companies that are in the early stages of their growth聽and have a unique聽value proposition. Most of them are not yet common household names.

A Defensive, Equities-Focused Portfolio

A portfolio that is defensive would tend to focus on consumer staples that are impervious to downturns. Defensive stocks do well in bad times as well as good times. No matter how bad the economy is at a given time, companies that make products that are essential to everyday life will survive.

An Income-Focused, Equities Portfolio

This type of portfolio makes money from dividend-paying stocks or other types of distributions to stakeholders. Some of the stocks in the income portfolio could also fit in the defensive portfolio, but here they are selected primarily for their high yields. An income portfolio should generate positive cash flow.聽Real estate investment trusts聽(REITs) are examples of income-producing investments.

A Speculative, Equities-Focused Portfolio

A speculative portfolio is best for investors that have a high level of tolerance for risk. Speculative plays could include聽initial public offerings聽(IPOs) or stocks that are rumored to be takeover targets. Technology or health care firms聽in the process of developing a single breakthrough product also would fall into this category.聽

Impact of Risk Tolerance on Portfolio Allocations

Although a financial advisor can create a generic portfolio model for an individual, an investor's risk tolerance should significantly reflect the portfolio's content.

For example, a conservative investor might favor a portfolio with large-cap value stocks, broad-based market index funds, investment-grade bonds, and a position in liquid, high-grade cash equivalents.

In contrast, a risk-tolerant investor might add some small-cap growth stocks to an aggressive, large-cap growth stock position, assume some high-yield bond exposure, and look to real estate, international, and alternative investment opportunities for their portfolio. In general, an investor should minimize exposure to securities or asset classes whose volatility makes them聽uncomfortable.

Impact of Time Horizon on Portfolio Allocations

Similar to risk tolerance, investors should consider how long they have to invest when building a portfolio. In general, investors should be moving toward a conservative asset allocation as their goal date approaches, to protect the portfolio's earnings up to that point.

Take, for example, an investor saving for retirement who's planning to leave the workforce in five years. Even if that investor is comfortable investing in stocks and riskier securities, they might want to invest a larger portion of the portfolio in more conservative assets such as bonds and cash, to help protect what has already been saved. Conversely, an individual just entering the workforce may want to invest their聽entire portfolio in stocks, as they聽may have decades to invest, and the ability to ride out some of the market's short-term volatility.
