Indices in the stock market help track market performance. These are quite helpful as they provide an in-depth understanding of market conditions, enabling informed decisions. There are several indices meant for different purposes. Two of these are sectoral and thematic indices. These two are aimed at understanding different sectoral and thematic performances of stocks in the stock market.
On the one hand, there are sectoral indices that target specific sectors, such as banking and IT, to assess their performance. On the other hand, there are thematic indices used to understand the performance of stocks based on themes such as environment and governance.
If you are looking to align your portfolio for maximum returns and manage risks and rewards, understanding sectoral and thematic indices can be quite helpful. In this guide, we will discuss sectoral vs thematic indices. So, read on for more details.
What Are Sectoral Indices?
Sectoral indices are stock market indices that track the performance of companies within a specific sector or industry. Sectoral indices provide information on the trend and health of specific market segments, such as technology, healthcare, or finance. By classifying businesses operating in the same industry, sectoral indices enable investors to examine sectoral performance and make sound investment choices.
For instance, the Nifty IT Index comprises prominent Indian IT majors that represent the sector's performance. Likewise, the Nifty Bank Index comprises top banking organisations, providing a gauge of the banking sector's performance.
A sectoral index is ideal for investors seeking to gain exposure to a specific industry or compare the relative performance of various sectors within the economy. They serve as a benchmark for sector-specific mutual funds and exchange-traded funds (ETFs), facilitating portfolio diversification and risk mitigation.
What Are Thematic Indices?
Thematic indices are market indices that track the performance of firms identified with a specific investment theme, regardless of their industry classification. Such themes can range from macroeconomic trends, technological progress, to social and environmental considerations. Thematic indices enable investors to capitalise on long-term structural patterns by investing in a diverse group of firms that are positive beneficiaries of these broad themes.
For example, the Nifty100 ESG Index covers firms that fulfil some environmental, social, and governance (ESG) requirements, favouring sustainable and ethical investing. An example is the Nifty India Defence Index, which tracks firms engaged in India's defence industry, reflecting the government's emphasis on indigenous defence manufacturing.
A thematic index is an attractive instrument for those investors who want to allocate their portfolios into particular global themes or trends. They give access to upcoming opportunities and can act as benchmarks for thematic mutual funds and ETFs.
Types of sectoral and thematic indices
There are various types of sectoral and thematic indices that you should be aware of. These are:
Sectoral Indices:
These indices focus on specific industry sectors, providing benchmarks for sector-specific investment strategies. Examples include:
Tracks the performance of automobile manufacturers and related companies.
Comprises companies in the fast-moving consumer goods sector.
Includes major pharmaceutical companies.
Covers companies in the metal and mining sector.
Thematic Indices
These indices comprise companies from various sectors that share a common investment theme. Examples include:
Focuses on companies with strong environmental, social, and governance practices.
Tracks companies benefiting from domestic consumption growth.
Includes companies involved in electric vehicles and related technologies.
Comprises companies driving digital transformation in India.
Both sectoral and thematic indices serve as essential tools for investors to analyse market trends, diversify portfolios, and align investments with specific sectors or themes
