## Revenue Scale & Growth Durability

What the numbers say: Supreme Petrochem Ltd is the scale leader at ₹5,720 crore, 35.4% ahead of Chemplast Sanmar Ltd. Styrenix Performance Materials Ltd's growth is 15.3% from a ₹3,438 crore base, with 19 reported observations in the 20-quarter window. Treat the growth leader as an acceleration candidate, not as equally proven scale.

Investor read: Supreme Petrochem Ltd is the scale benchmark; Styrenix Performance Materials Ltd is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.

This conclusion weakens if: Supreme Petrochem Ltd's growth falls below Styrenix Performance Materials Ltd's for two consecutive comparable reports while operating margin also compresses.

Evidence: Supreme Petrochem Ltd · ₹5,720 crore | 35.4% versus #2 · Chemplast Sanmar Ltd | 4/8 recent comparable periods | 7/7 companies · 125 observations

Definition: Revenue is compared on a common reported-currency basis. Growth is year-on-year, so seasonality does not masquerade as progress.

## Return On Capital Employed

What the numbers say: Kothari Petrochemicals Ltd leads ROCE at 28.6%, 4.8 percentage points above Bhansali Engineering Polymers Ltd. Bhansali Engineering Polymers Ltd has the strongest latest improvement at +2.1 percentage points. Read the leader beside the density of its reported history: a sparse high return is a candidate; a repeated high return is evidence of durability.

Investor read: Kothari Petrochemicals Ltd sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current roce change signal.

Evidence: Kothari Petrochemicals Ltd · 28.6% | 20.2% versus #2 · Bhansali Engineering Polymers Ltd | 2/8 recent comparable periods | 7/7 companies · 100 observations

Definition: ROCE asks how much operating return the business earns on the capital employed. Direction matters, but a single exceptional year should not be mistaken for durability.

## Valuation Against Growth & Quality

What the numbers say: Bhansali Engineering Polymers Ltd has the lowest comparable PEG at 0.32×, 56.2% below Supreme Petrochem Ltd. Only 4 of 7 companies have earnings and growth steady enough for the ratio to mean anything, so no broad “cheapest stock” conclusion is defensible unless the current multiple, own-history position and growth durability agree.

Investor read: Treat valuation as permission to investigate, never as a standalone reason to buy.

This conclusion weakens if: The next two comparable reports reverse the current p/e signal.

Evidence: Bhansali Engineering Polymers Ltd · 0.32× | 56.2% versus #2 · Supreme Petrochem Ltd | 0/8 recent comparable periods | 4/7 companies · 24 observations

Definition: PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is recomputed consistently as the trailing P/E divided by that growth rate — reported earnings, never an expected-earnings multiple. On Indian companies it is shown only where the two data feeds agreed. Where any of that fails the ratio is left out rather than printed: a P/E divided by a loss, or by growth measured off a tiny base, is a number that looks precise and means nothing.

## What can make this comparison misleading?
- A high growth rate can be a low-base artefact. The page keeps level and change separate for that reason.
- A high ROCE can be temporary or flattered by a small capital base. Read it beside margin, cash conversion and reinvestment.
- The 4-Factor Sector Score ranks research priority, not portfolio action. Management quality, catalysts and risks need equally fresh evidence before capital is deployed.
- An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.
- 2 companies draw at least one figure from a second data feed with too little overlapping history to cross-check against the primary source; they are marked unverified wherever those figures appear.

### How much history does this Petrochem - Polymers comparison include?

The page compares up to 20 reported quarters per company for fundamentals, returns and valuation, ending Jun 2026. Missing observations remain blank rather than being estimated.

### How is the 4-Factor Sector Score calculated?

The four visible contributions add directly: growth and earnings up to 35 points, capital efficiency up to 25, valuation up to 20, and relative strength up to 20. Missing or stale evidence moves only the affected contribution toward neutral.

### What is the Nifty Petrochem - Polymers index?

The Nifty Petrochem - Polymers index tracks India's listed Petrochem - Polymers companies as a single basket. This page follows the same 7 companies and equal-weights them, so every company's weekly return counts once whatever it is worth, and the reading belongs to the Petrochem - Polymers sector rather than to its largest constituent. Figures are as of Jun 2026.

### Which are the best Petrochem - Polymers stocks in India?

Ranked by this page's four-factor score, Bhansali Engineering Polymers Ltd places first among 7 listed Petrochem - Polymers companies, followed by Kothari Petrochemicals Ltd. That is a ranking of published data — earnings, quality, valuation and market behaviour as of Jun 2026 — and not a recommendation; Sector Alpha is not registered with SEBI as an investment adviser.

### How many Petrochem - Polymers stocks are listed in India?

This comparison covers 7 listed Petrochem - Polymers companies in India, each above the size floor the site applies, with 20 quarters of reported figures per company where the filings exist. The full ranked list is on this page, as of Jun 2026.

### Which Petrochem - Polymers company is the biggest?

Supreme Petrochem Ltd is the largest, with trailing-twelve-month revenue of ₹5,720 crore, ahead of Chemplast Sanmar Ltd at ₹4,224 crore. That covers 7 of 7 companies with comparable reporting through Jun 2026.

### Which Petrochem - Polymers company has the best profit margins?

Supreme Petrochem Ltd has the highest operating margin at 19%, from 7 of 7 comparable companies. Chemplast Sanmar Ltd shows the biggest recent improvement, at +11.8 percentage points. A high margin matters most when it is holding or rising, not when it is peaking.

### Which Petrochem - Polymers company makes the most profit?

Supreme Petrochem Ltd earns the most, at ₹486 crore of trailing-twelve-month net profit, from 7 of 7 comparable companies. Manali Petrochemicals Ltd has the fastest profit growth at 100%, though growth off a small or recovering profit base overstates how much has actually changed.

### Which Petrochem - Polymers company earns the highest return on capital?

Kothari Petrochemicals Ltd leads on return on capital employed at 28.6%, across 7 of 7 companies. Read it beside the length of its reported history: a high return that repeats for years is evidence of a durable business, while a single high reading can be a small capital base or one good year.

### Which Petrochem - Polymers stock is the cheapest?

On PEG — where a LOWER number is cheaper — Bhansali Engineering Polymers Ltd screens cheapest at 0.32×. Only 4 of 7 companies have earnings and growth steady enough for the ratio to mean anything, so this is not a sector-wide "cheapest stock" verdict. Cheap on a multiple is a reason to investigate, never a reason to buy on its own.

### Is the Petrochem - Polymers sector beating the market?

Petrochem - Polymers has underperformed NIFTY 500 by 14% over the last 52 weeks and 2.7% over 13 weeks, measured on an equal-weight index of its current members. Inside the sector, 4 of 7 covered companies are beating the market on their own. Sector strength does not transfer evenly to every stock in it.

### Which Petrochem - Polymers stock has the strongest price momentum?

Bhansali Engineering Polymers Ltd has the strongest relative strength against NIFTY 500. Relative strength answers last, after growth, quality and valuation: price can move well before the fundamentals confirm it, and sometimes without them confirming at all.

### Which Petrochem - Polymers company scores highest for research priority?

Bhansali Engineering Polymers Ltd scores 70.3 out of 100 with 87% evidence confidence, from 21.5 points on growth and earnings, 17.9 on capital efficiency, 15.9 on valuation and 15 on relative strength. This ranks what deserves work next. It is not a buy recommendation, and management quality, catalysts and risk still need separate research.

### How many Petrochem - Polymers companies does this comparison cover, and over what period?

It compares 7 listed companies over up to 20 reported quarters of fundamentals, ending Jun 2026, plus weekly price and relative-strength history. Membership is the full sector list — nothing is dropped for having thin data.

### What is the total market cap of the Petrochem - Polymers sector?

The 7 Petrochem - Polymers companies on this page carry ₹28,404 crore of combined market value. Supreme Petrochem Ltd is the largest at ₹13,410 crore, about 47% of the sector's total on its own. Market value moves with price, so this reading is dated 2026-08-05.

### What is the Petrochem - Polymers sector's P/E ratio?

The median price-to-earnings ratio across the 7 Petrochem - Polymers companies on this page is 23.6×, measured on the 6 that report a comparable figure. A sector-level history for this multiple is not held here, so this is a cross-section of today, not a comparison with the sector’s own past. Figures are as of 2026-08-05.

### How is the Petrochem - Polymers sector performing?

4 of the 7 covered Petrochem - Polymers companies are beating NIFTY 500 on Mansfield relative strength. The sector itself is 14% behind NIFTY 500 over 52 weeks on an equal-weight index of its current members. Readings are as of 2026-08-05.

### Why are some values on this page blank?

A blank means that company did not report a comparable figure for that period, so nothing is shown. Missing observations are never interpolated, carried forward, or replaced with a similar-looking accounting line, and a company with missing evidence has its research score pulled toward neutral rather than being scored as bad.

### Is this investment advice?

No. Every figure here is a deterministic calculation from reported company filings and market data, published for research. It contains no recommendation to buy or sell any security, does not account for your circumstances, and is not a substitute for advice from a licensed adviser.
