Portfolio Diversification – Background Part 1

Portfolio Diversification – Background Part 1

Diversification in an investing portfolio is an important component to managing risk to achieve more stable or consistent returns to reach your financial goals.  By spreading your investments over a mix of assets with different risks and returns, if one investment performs poorly, it will be hopefully balanced by the better performance of another.  Profits or risk of loss cannot be guaranteed by diversifying, but some of the effects of the market’s volatility may be mitigated.

Some basic investing definitions:

  • Bond:  loan to a government, agency, or company that is repaid with interest
  • Asset Mix: breakdown of all of the assets within a portfolio, such as stocks, bonds, cash, and other investments
  • Bear Market: trend when stock prices fall for a sustained period of time,usually > 20% from a recent peak
  • Bull Market: trend in which stock prices increase for an extended period of time, usually > 20% from a recent low
  • Capital Appreciation: increase in the value of an asset over time
  • Capital Preservation: strategy that aims to protect an investment and limit potential losses
  • CD (Certificate of Deposit): fixed income investment that pays a set rate of interest over a fixed time period
  • Commodities: A raw material or product that can be bought or sold.  Hard commodities include natural resources that are mined or extracted such as gold or oil.  Soft commodities are agricultural products or livestock such as sugar, wheat, and beef.
  • Common Stock: A share represents a unit of ownership of a company usually traded on an exchange or through a brokerage
  • Equities: ownership stake in an asset or company usually referring to publicly traded stocks
  • ETF (Exchange Traded Fund): Basket of securities that trades like stocks on an exchange or through a brokerage
  • Horizon: the amount of time planned for an investment to mature or reach a goal
  • Index: Calculation of the value of a specific financial market or segment of that market
  • Market Capitalization: total value of a company’s outstanding shares in the stock market. It’s calculated by multiplying the current stock price by the total number of shares.
  • Market Correction: sustained decline in the market, usually a 10% to 20% drop in value from a recent peak
  • Market (or Business) Cycle: The business cycle is the collection of stages that an economy goes through as it expands, slows down, and declines.
  • Money Market Fund: Mutual fund that invests in debt securities characterized by short maturities with minimal credit risk
  • Mutual Fund: A mutual fund pools together money from many investors to purchase a collection of stocks, bonds, or other securities
  • Recession: The National Bureau of Economic Research (NBER) defines a recession as “a significant decline that lasts for more than a few months and affects the broader economy, not just a particular sector”
  • Stock Market Crash: steep and sudden decline in the stock market

The U.S. Securities and Exchange Commission has a lot of good information to start with and tips on how to prevent investment fraud.

There are multiple ways to diversify a portfolio.  Some considerations are investing horizon (how long for investment to grow), geography (U.S vs. international stocks), market capitalization (large, mid, or small companies), industry sector, alternative investments (real estate and commodities), bonds, short term or cash equivalents, and market cycle.  If investing in individual stocks, follow the 5% rule where a single stock should not make up more than 5% of your portfolio. Some investors also consider dividend growth if investing in individual stocks for an income stream.  Mutual Funds and ETFs (Exchange-traded funds) are similar in that they both offer a pool or baskets of investments to provide some “instant” diversification.  One difference is that mutual fund transactions are only processed at the end of the trading day. ETFs can be bought and sold throughout the market trading day.

Most of my portfolio is constructed around mutual funds for easy built-in convenience and diversification.  When evaluating mutual funds in a given investing category, I look at the manager’s tenure, fund’s expense costs, and performance compared to other funds in the same class or the underlying investing index (if applicable).  I do have some individual stocks in my non-retirement account, but they are primarily a left-over when when I was teaching my kids investing and opened brokerage trusts for them.

I will use the Morningstar investment categories for classifications of mutual funds.  Lipper is another source for comparison of funds.  I have discovered that the two do not always match in their categorization.  Morningstar has retrospective “star” ratings for past performance and “medalist” ratings for future performance estimation.  Lipper has retrospective ratings and places a higher weighting on more recent portfolio mix.

Morningstar Categories (Portfolio Diversification):

Equity

  • Large Cap: Stocks in the top 70% of the capitalization of the U.S. equity market are defined as large cap.
  • Mid-Cap: The market capitalization range for U.S. mid-caps typically falls between $1 billion and $8 billion and represents 20% of the total capitalization of the U.S. equity market.
  • Small Cap:  Stocks in the bottom 10% of the capitalization of the U.S. equity market are defined as small cap.
  • International Equity Funds –Stock funds that have invested 40% or more of their equity holdings in foreign stocks (on average over the past three years) are placed in an international-stock category.
    • Global:  World stock portfolios have few geographical limitations. It is common for these portfolios to invest the majority of their assets in developed markets, with the remainder divided among the globe s emerging markets. These portfolios are not significantly overweight U.S. equity exposure relative to the Morningstar Global Market Index and maintain at least a 20% absolute U.S. exposure
    • Foreign : Most of these portfolios divide their assets among a dozen or more developed markets, including Japan, Britain, France, and Germany.  These portfolios typically will have less than 20% of assets invested in U.S. stocks.
    • Diversified Emerging Markets Funds – Diversified emerging-markets portfolios tend to divide their assets among 20 or more nations, although they tend to focus on the emerging markets of Asia and Latin America rather than on those of the Middle East, Africa, or Europe.
  • Growth: Growth is defined based on fast growth (high growth rates for earnings, sales, book value, and cash flow) and high valuations (high price ratios and low dividend yields).
  • Blend: The blend style is assigned to portfolios where neither growth nor value characteristics predominate.
  • Value: Value is defined based on low valuations (low price ratios and high dividend yields) and slow growth (low growth rates for earnings, sales, book value, and cash flow).
  • Asset Allocation Funds: Funds in allocation categories seek to provide both income and capital appreciation by primarily investing in multiple asset classes, including stocks, bonds, and cash.  Funds in balanced categories offer investors a mix of stocks and bonds to provide capital appreciation, income, diversification, or specific allocations based on planned retirement dates. This group also includes funds that invest in convertibles, which act a bit like stocks and a bit like bonds.
    • Moderately Aggressive Allocation: These moderately aggressive strategies prioritize capital appreciation over preservation. They typically expect volatility similar to a strategic equity exposure between 70% and 85%.
    • Moderate Allocation: These moderate strategies seek to balance preservation of capital with appreciation. They typically expect volatility similar to a strategic .  equity exposure between 50% and 70%.
    • Moderately Conservative Allocation: These moderately conservative strategies prioritize preservation of capital over appreciation. They typically expect volatility similar to a strategic equity exposure between 30% and 50%.
  • Sector Equity Funds – Equity funds that focus on stocks in a specific sector, such as energy, real estate, or precious metals.
    • Health – Health portfolios focus on the medical and health-care industries. Most invest in a range of companies, buying everything from pharmaceutical and medical-device makers to HMOs, hospitals, and nursing homes. A few portfolios concentrate on just one industry segment, such as service providers or biotechnology firms.
    • Technology – Technology portfolios buy high-tech businesses in the U.S. or outside of the U.S. Most concentrate on computer, semiconductor, software, networking, and Internet stocks. A few also buy medical-device and biotechnology stocks, and some concentrate on a single technology industry.
    • Communications – Communications portfolios concentrate on telecommunications and media companies of various kinds. Most buy some combination of cable television, wireless-communications, and communications-equipment firms as well as traditional phone companies. A few favor entertainment firms, mainly broadcasters, film studios, publishers, and online service provide
    • Consumer Cyclical – Consumer cyclical portfolios seek capital appreciation by investing in equity securities of U.S. or non-U.S. companies in the consumer cycle
    • Industrials – Industrial portfolios seek capital appreciation by investing in equity securities of U.S. or non-U.S. companies that are engaged in services related to cyclical industries. This includes and is not limited to companies in aerospace and defense, automotive, chemicals, construction, environmental services, machinery, paper, and transportation.
    • Natural Resources – Natural-resources portfolios focus on commodity-based industries such as energy, chemicals, minerals, and forest products in the United States or outside of the United States. Some portfolios invest across this spectrum to offer broad natural-resources exposure. Others concentrate heavily or even exclusively in specific industries. Portfolios that concentrate primarily in energy-related industries are part of the equity energy category.
    • Real Estate Funds – Real estate portfolios invest primarily in real estate investment trusts of various types. REITs are companies that develop and manage real estate properties. There are several different types of REITs, including apartment, factory-outlet, health-care, hotel, industrial, mortgage, office, and shopping center REITs. Some portfolios in this category also invest in real estate operating companies.
    • Financial – Financial portfolios seek capital appreciation by investing primarily in equity securities of U.S. or non-U.S. financial-services companies, including banks, brokerage firms, insurance companies, and consumer credit providers
    • Bank Loan – Bank-loan portfolios primarily invest in floating-rate bank loans and floating-rate below investment-grade securities instead of bonds. In exchange for their credit risk, these loans offer high interest payments that typically float above a common short-term benchmarks such as Libor or SOFR.
    • Utilities – Utilities portfolios seek capital appreciation by investing primarily in equity securities of U.S. or non-U.S. public utilities including electric, gas, and telephone-service providers.
    • Equity Energy – Equity energy portfolios invest primarily in equity securities of U.S. or non-U.S. companies who conduct business primarily in energy-related industries. This includes and is not limited to companies in alternative energy, coal, exploration, oil and gas services, pipelines, natural gas services, and refineries

Fixed Income

  • High Yield Bond Funds – High-yield bond portfolios concentrate on lower-quality bonds, which are riskier than those of higher- quality companies. These portfolios generally offer higher yields than other types of portfolios, but they are also more vulnerable to economic and credit risk. These portfolios primarily invest in U.S. high- income debt securities where at least 65% or more of bond assets are not rated or are rated by a major agency such as Standard & Poor’s or Moody’s at the level of BB (considered speculative for taxable bonds) and below.
  • Corporate Bond Funds – Corporate bond portfolios concentrate on investment-grade bonds issued by corporations in U.S. dollars, which tend to have more credit risk than government or agency-backed bonds. These portfolios hold more than 65% of their assets in corporate debt, less than 40% of their assets in non-U.S. debt, less than 35% in below-investment-grade debt, and durations that typically range between 75% and 150% of the three-year average of the effective duration of the Morningstar Core Bond Index.
  • Intermediate-Term Core-Plus Bond Funds – Intermediate-term core-plus bond portfolios invest primarily in investment-grade U.S. fixed-income issues including government, corporate, and securitized debt, but generally have greater flexibility than core offerings to hold non-core sectors such as corporate high yield, bank loan, emerging-markets debt, and non-U.S. currency exposures. Their durations (a measure of interest-rate sensitivity) typically range between 75% and 125% of the three-year average of the effective duration of the Morningstar Core Bond Index.
  • Intermediate-Term Core Bond Funds – Intermediate-term core bond portfolios invest primarily in investment-grade U.S. fixed-income issues including government, corporate, and securitized debt, and hold less than 5% in below-investment-grade exposures. Their durations (a measure of interest-rate sensitivity) typically range between 75% and 125% of the three-year average of the effective duration of the Morningstar Core Bond Index.
  • Multisector Bond – Multisector-bond portfolios seek income by diversifying their assets among several fixed-income sectors, usually U.S. government obligations, U.S. corporate bonds, foreign bonds, and high-yield U.S. debt securities. These portfolios typically hold 35% to 65% of bond assets in securities that are not rated or are rated by a major agency such as Standard & Po  or’s or Moody’s at the level of BB (considered speculative for taxable bonds) and below.

Stocks or equities have traditionally represented the most aggressive portion of a portfolio with the highest potential for growth.  I am not including some of the newer investing options such as cryptocurrency and non-fungible tokens (NFTs) as they are not currently allowed in most company sponsored retirement plans.  Bonds usually provide an income stream paying dividends and are considered less volatile than stocks.  Short term investments such as money markets and CDs are the most conservative and stable investments but offer a lower rate of return.  Stocks and bonds tend to perform differently during various parts of the market cycle.

“Critically, different asset classes have different ‘systemic risk‘, which describes how they respond to the market at large. For example, when the stock market does well, commodities and bonds tend to do poorly. Conversely, commodities and bonds rise when stocks fall.”https://smartasset.com/investing/guide-portfolio-optimization-strategies
