An introduction to sector investing

QuietGrowth - An introduction to sector investing

Sector investing is an investing strategy where an investor focuses on investments in a specific sector of the economy, such as technology, healthcare, or energy. The idea is to take advantage of growth opportunities and potential outperformance of companies within that sector. This approach differs from a more diversified investment strategy, where investments are spread across multiple sectors and industries.

Different types of sector investing

There are different types of sector investing, including

  • Industry sector investing: This involves investing in specific industries, such as technology, healthcare, financials, or consumer goods.
  • Cyclical sector investing: This involves investing in industries that are sensitive to changes in the business cycle, such as consumer discretionary, energy, and materials.
  • Defensive sector investing: This involves investing in industries that are less sensitive to changes in the business cycle, such as utilities, healthcare, and consumer staples.

It’s important to remember that each type of sector investing has its unique risks and rewards, and the suitability of each type depends on the investor’s financial goals, risk tolerance, and investment time horizon.

Examples of sector investing

Some of the prominent sectors in sector investing are:

  • Consumer discretionary
  • Consumer staples
  • Energy
  • Financials
  • Healthcare
  • Industrials
  • Information technology
  • Materials
  • Real estate
  • Telecommunications
  • Utilities

History of sector investing

The history of sector investing can be traced back to the late 19th and early 20th centuries when industry-specific mutual funds were introduced. These early funds allowed investors to gain exposure to specific sectors, such as transportation or utilities, through a diversified portfolio of stocks.

In the 1960s and 1970s, sector investing became more popular as institutional investors and pension funds began to allocate assets to specific sectors. This trend was further fueled by the advent of index funds in the 1980s and 1990s, which enabled individual investors to invest in specific sectors with low fees and minimal effort.

Today, sector investing is a common strategy for many investors, with a wide range of sector-specific exchange-traded funds (ETFs) and mutual funds available. These investment vehicles provide convenient and cost-effective access to specific sectors.

History of sector investing indices

The history of sector investing indices dates back to the late 1970s and early 1980s when the first sector-specific indices were introduced. One of the first sector-specific indices was the Morgan Stanley Capital International (MSCI) Information Technology Index, which was created in 1986. This was followed by the introduction of sector indices for other industries, such as healthcare, consumer staples, and energy.

In the 1990s and 2000s, the popularity of sector investing grew rapidly as index providers introduced a more comprehensive range of sector indices and investment products based on these indices. Today, sector indices exist for almost every major industry and sub-sector.

Advantages and disadvantages of sector investing

Advantages of sector investing include:

  • Focus for experts: Investors who are experts in a specific sector can focus on that sector and make informed investment decisions.
  • Potential for higher returns: Certain sectors may perform better than the overall market, providing the potential for higher returns. However, the returns of sector investing can vary widely, and the returns of some sector investments might underperform broad-based index investing.
  • Diversification within a sector: Investors can spread their investments across several companies within a sector to reduce risk.

Disadvantages of sector investing include:

  • Volatility: Sectors can be volatile and subject to market fluctuations, leading to higher risks for investors. Specific sectors can be more volatile than the broader market.
  • Lack of diversification: Focusing investments in one sector can increase portfolio risk, as those investments are tied to the performance of that sector.
  • Dependence on sector performance: The success of sector investments depends on market conditions and the performance of the sector as a whole rather than individual company performance.

Overall, sector investing can be a useful strategy for investors with a higher tolerance for risk and a strong understanding of the sector in which they are investing.

Sector investing and long-term investing approach

Sector investing can be used as a long-term or short-term investing approach, depending on the investor’s goals, risk tolerance and investment time horizon.

Long-term investors can use sector investing to benefit from long-term growth opportunities in specific industries.

However, sector investing can also be used as a short-term or mid-term investing strategy, where investors seek to take advantage of short-term market movements, shifts in sector performance, or industry cycles.

Sector investing and thematic investing

Sector investing and thematic investing are among the prevalent investment strategies, each with advantages and disadvantages.

Thematic investing, a more recent phenomenon, is gaining popularity as investors have become increasingly interested in investing in companies and industries aligned with their values and beliefs. This has led to a growing number of thematic ETFs and mutual funds, providing investors access to specific themes such as clean energy or cybersecurity.

Some investors prefer sector investing because it provides a more straightforward and conventional approach. In contrast, others prefer thematic investing because it allows them to invest in companies aligned with their values and beliefs.

Reception of sector investing among financial advisers

The reception of sector investing among financial advisers is generally favourable. Many financial advisers consider sector investing a useful tool for diversifying portfolios and achieving specific investment objectives.

However, like all investment strategies, sector investing has advantages and disadvantages, and financial advisers must carefully consider the risks and benefits before making recommendations to their clients.
