Why there is no dedicated Index pertaining to CHEMICAL Sector in BSE and NSE?

That’s a very insightful question — and as of now, neither BSE (Bombay Stock Exchange) nor NSE (National Stock Exchange) has a dedicated “Chemical Sector Index”, unlike other sectors such as IT, Banking, FMCG, or Pharma.

Here’s why that is the case:

1. The Chemical Sector in India is Highly Diverse

The Indian chemical industry is extremely broad, covering:

• Petrochemicals
• Specialty chemicals
• Agrochemicals
• Fertilizers
• Paints and dyes
• Industrial gases
• Plastics and polymers

Because these sub-sectors operate under different business models, margins, and market drivers, it’s difficult to group them meaningfully into one representative index.
For example:

• Reliance Industries (petrochemicals) behaves differently from
• Aarti Industries or PI Industries (specialty chemicals/agrochemicals), or
• Asian Paints (downstream user of chemicals).

Hence, no single composite index would accurately represent them all.

2. Limited Number of Large Listed Pure-Play Chemical Companies

While there are several listed chemical firms, many are mid-cap or small-cap, and large diversified conglomerates (like Reliance, Tata Chemicals, Grasim, etc.) have chemical divisions but are not pure-play chemical companies.
This makes it harder for exchanges to form a liquid and investable index that meets inclusion criteria such as:

• Minimum market capitalization
• Sufficient trading volumes
• Sectoral homogeneity

3. Existing Sector Indices Already Cover Some Chemical Stocks

Stocks from the chemical sector are already included in broader indices, such as:

• Nifty 500 or Nifty 200 (broad-market indices)
• Nifty Commodities Index
• Nifty Basic Materials Index
• BSE Basic Materials Index

These indices indirectly represent the performance of chemical companies, so exchanges might have felt a separate chemical index wasn’t necessary yet.

4. Lack of Investor Demand (So Far)

Sectoral indices are often created based on market demand — especially from ETF issuers, mutual funds, or large investors who want to track a sector.
Since thematic or sectoral ETFs in India have mainly focused on IT, Banking, Pharma, and FMCG — sectors with clearer boundaries and larger caps — the demand for a “Chemical Index” has been limited.

5. Possible Future Development

Given India’s rapid growth in specialty chemicals, exchanges may introduce a dedicated index in the future.
In fact, there have been discussions within industry circles about creating a “Nifty Specialty Chemicals Index”, but as of 2025, no such index has been launched.

Annexure -1: Hypothetical “Chemical Sector Index

Here’s a hypothetical “Chemical Sector Index” for the Indian markets — let’s call it the “Nifty Chemical Index (Hypo)”. I’ll outline what its rules could be, select sample constituent stocks, estimate weights, and highlight limitations. This is for illustration only, not a real index.

1. Proposed Index Rules

• Universe: Listed companies on National Stock Exchange of India (NSE) or Bombay Stock Exchange (BSE) whose main business is in the chemical sector (specialty chemicals, inorganic/organic chemicals, agrochemicals, petrochemicals, etc).
• Size filter: Market Capitalisation above a certain threshold (say Rs.10,000 crore) and adequate liquidity (average daily volume).
• Sector classification: Firms whose primary activity falls under “Chemicals” as per industry classification.
• Weighting: Free-float market-cap weighted, with capping (e.g., no one company >15% weight).
• Review: Semi-annual review for inclusion/exclusion.

2. Sample Constituents & Proposed Weights

Based on lists of large chemical companies in India. (Sharescart)
Here are some sample names, approximate weights (for a 10-stock index).

Total ˜ 100% (weights rounded).
This gives a fairly well-diversified index among major chemical players.

3. Interpretation & Use

• This hypothetical index would reflect how the chemical industry in India is performing via the share-price movements of major chemical companies.

• Investors could track trends in chemical sector growth (import substitution, speciality chemicals, etc).

• Could serve as basis for a fund/ETF if one were launched.

4. Limitations & Caveats

• The sector is very diverse (bulk chemicals, agrochemicals, specialty chemicals, petrochemicals, industrial gases). So the index may still represent a mix rather than a purely homogeneous “chemical” theme.

• Some large companies have significant non-chemical businesses — e.g., Tata Chemicals has a diversified group parent; inclusion may dilute pure chemical exposure.

• Liquidity & free-float criteria matter — some chemical firms might have low trading volumes, making them less investable.

• Weight-capping needs to be handled so that one giant player doesn’t dominate the index.

• Historical back-testing of such an index would be needed to validate its usefulness (which we haven’t done here).

• Regulatory/industry changes (e.g., raw-material price swings, environmental regulation) may disproportionately affect this sector.

5. Why This Might Make Sense Now

• The chemical industry in India is growing rapidly: e.g., India is the 6th largest chemical producer globally and 3rd in Asia. (Pocketful.in)

• Many specialist chemical companies are achieving strong 5-year CAGR. (Angel One)

• Investors may increasingly want thematic exposure (e.g., import-substitution, speciality chemicals) and such an index could fill a gap.

Annexure – 2: Rough simulation of how the hypothetical “Chemical Sector Index” might have performed over the past few years.

Here’s a rough simulation of how the hypothetical “Chemical Sector Index” might have performed over the past few years, based on approximate numbers for key constituent stocks. This is illustrative only (not precise) and should be taken with caution.

Summary of Assumptions

• Constituents: 10 companies (as per previous list).

• Initial index base level: 1000 points at start of 2020.

• Weights assumed:

  • Pidilite Industries Ltd Rs.15%

  • SRF Ltd Rs.12%

  • Deepak Nitrite Ltd Rs.8%

  • and others (remaining Rs.65%) spread across other firms with assumed smaller weights.

• We approximate returns for the three large names (because historical data is available) and assume “average” returns for the rest (~+5 % per year) to fill out the index.

• Returns are compounded annually for simplicity.

Approximate Return Figures

Pidilite Industries:

• From a quoted historical table: 2020 Rs.1,735.5, 2021 Rs.2,429.6, 2022 Rs.2,526.6, 2023 Rs.2,701.4, 2024 Rs.2,904.3. (Stock Price Archive)
• Approximate annual returns: 2020-2021 ~ +40 %, 2021?2022 ~ +4 %, 2022?2023 ~ +7 %, 2023?2024 ~ +7.5 %.

SRF Ltd:

• Current price Rs.3,082 as of late Oct 2025. (The Economic Times)
• 52-week range: Rs.2,126 to Rs.3,325. (Chola Securities)
• We’ll assume moderate growth ~+10–20 % per year over recent years for this simulation.

Deepak Nitrite:

• Current price ~ ?1,845 (Aug 2025) (Business Standard)
• 52-week high ~ ?3,094.7, 52-week low ~ ?1,780.5. (Business Standard)
• Recent 12-month performance ~ –40 % per the source. (Business Standard)

Simulated Index Performance

Starting at 1000 points on 1 Jan 2020. Assuming constituent weightings above and applying the annual returns roughly:

Key Takeaways

• The simulated index shows strong growth from 2020 to ~2024 (roughly +86% total) under these assumptions.
• However, recent 2024-25 performance likely weaker, especially because some constituents are down significantly (e.g., Deepak).
• The sector as a whole appears to have a mixed performance: large firms with strong growth (Pidilite) balanced by others facing headwinds (Deepak, SRF).
• This illustrates how a dedicated chemical sector index could outperform in good years, but also underperform when key players stumble.

Important Caveats

• These are rough estimates: actual returns will differ materially because I used partial data and assumed returns for many constituents.
• The index ignores dividends, corporate actions (splits/bonus), weight changes, re-balancing, and survivorship bias.
• Some companies in the sector have volatile earnings (raw material costs, regulatory issues) which means risk is higher.
• Past performance is not a reliable indicator of future results.

In summary:

There’s no dedicated Chemical Sector Index on BSE/NSE mainly because the sector is too diverse, lacks enough large pure-play companies, and hasn’t yet attracted sufficient investor demand for a standalone benchmark.
