What is Sector Breakdown?

751 reads · Last updated: December 5, 2024

A sector breakdown is the mix of industry sectors, like technology or healthcare, held by a fund or portfolio, typically expressed as a percentage. Sector designations can vary depending on the fund’s investment criteria and overall objective.

Definition

Industry allocation refers to the composition of various industry sectors held within a fund or investment portfolio, such as technology or healthcare, usually expressed as a percentage. Industry classifications may vary based on the fund's investment criteria and overall objectives.

Origin

The concept of industry allocation originated with the development of modern portfolio theory, particularly in the mid-20th century, when investors began to recognize the importance of diversified investments. By allocating assets across different industries, investors can reduce the impact of volatility in any single industry on the overall portfolio.

Categories and Features

Industry allocation can be categorized according to different industry classification standards, such as the Global Industry Classification Standard (GICS) or the Standard & Poor's industry classifications. Each classification method has its unique features and application scenarios. For example, GICS divides industries into 11 major categories, such as Information Technology, Financials, and Healthcare. Different industry allocation strategies can help investors achieve specific investment goals, such as growth, income, or risk management.

Case Studies

Case Study 1: During the 2008 financial crisis, some funds successfully reduced overall risk by increasing investments in the healthcare industry, which is less affected by economic cycles. Case Study 2: In 2020, many technology funds benefited from high allocations in the Information Technology sector due to the growth of remote work and online services.

Common Issues

Common issues investors face when applying industry allocation include over-concentration in a single industry, leading to increased risk. Additionally, changes in industry classifications may necessitate portfolio rebalancing, increasing transaction costs. Investors should regularly review their industry allocation to ensure it aligns with their investment goals and risk tolerance.

Compound Annual Growth Rate

The compound annual growth rate (CAGR) is the rate of return (RoR) that would be required for an investment to grow from its beginning balance to its ending balance, assuming the profits were reinvested at the end of each period of the investment’s life span.CAGR provides a concise way to assess the overall performance of an investment over a period of time, regardless of fluctuations over time. Although CAGR is a useful metric, it may not fully reflect the actual compounding effect over the period, especially when the ROI fluctuates greatly.

Fibonacci Retracement

Fibonacci retracement levels, stemming from the Fibonacci sequence, are horizontal lines that indicate where support and resistance are likely to occur. Each level is associated with a specific percentage, representing the degree to which the price has retraced from a previous move. Common Fibonacci retracement levels include 23.6%, 38.2%, 50%, 61.8%, and 78.6%. These levels can be drawn between any two significant price points, such as a high and a low, to predict potential reversal areas. Fibonacci numbers are prevalent in nature, and many traders believe they hold significance in financial markets as well. Fibonacci retracement levels were named after the Italian mathematician Leonardo Pisano Bigollo, better known as Leonardo Fibonacci, who introduced these concepts to Western Europe but did not create the sequence himself.

Log-Normal Distribution

The Log-Normal Distribution is a statistical distribution where a random variable is said to follow a log-normal distribution if the logarithm of the variable is normally distributed. This type of distribution is often used to model positively skewed data occurring in various natural and social phenomena, such as income, city populations, stock prices, etc.

Order Driven Market

An order-driven market is a financial market where all buyers and sellers display the prices at which they wish to buy or sell a particular security, as well as the amounts of the security desired to be bought or sold. This kind of trading environment is the opposite of a quote-driven market, which only displays bids and asks of designated market makers and specialists for the specific security that is being traded.

The CDX was the first CDS index, which was created in the early 2000s and was based on a basket of single issuer CDSs.

Subprime Mortgage

A subprime mortgage is one that’s normally issued to borrowers with low credit ratings. A prime conventional mortgage isn’t offered, because the lender views the borrower as having a greater-than-average risk of defaulting on the loan.Lending institutions often charge interest on subprime mortgages at a much higher rate than on prime mortgages to compensate for carrying more risk. These are often adjustable-rate mortgages (ARMs) as well, so the interest rate can potentially increase at specified points in time.
