All 7 listed Indian Petrochem - Polymers companies are named here, largest first. This is the set of companies people mean when they search for a Nifty Petrochem - Polymers index; NSE publishes its own indices only for the largest sectors, so this equal-weighted set stands in for one. One large company cannot set the reading.

The line below covers up to 5.2 years and opens on the 5Y view; the buttons cut it shorter. Over the last two years (104 weeks) this sector is 26% behind NIFTY 500. Earnings across its companies grew 6% on average over the last four reported quarters, close to flat.

Price down, no fundamental support. 0 of 7 companies pass the momentum test (5+ points ahead of the Nifty 500 over 3 months, within 20% of the 52-week high).

Not ahead of NIFTY 500 on the three-month view this week; 2 of the 7 companies in the industry index above their 200-day average (3 fewer than four weeks earlier); 0 of those 7 pass the momentum test (4 fewer than four weeks earlier); earnings rising at 6 of the 7 that report earnings.

Not ahead of NIFTY 500, not building participation, not giving any back. Earnings confirming, 6 of 7 members have higher trailing twelve-month earnings than a year ago.

Both lines start at 200 in the same week, so the gap between them tells the story: the sector line is an equal-weighted index of its 7 companies. The bars underneath are trailing 12-month earnings per share, one bar per reported quarter, each member set to 100 at the start and the sector taking the middle value, so a price line pulling away from flat bars means the market is paying more for the same earnings. A bar turns grey when that figure is lower than the quarter before. The rules are fixed and the same everywhere on this site: ahead by 5% or more over three months, or behind by 20% or more over a year while earnings grew 20% or more. Hover or tap any point to read both values and the gap.

Petrochem - Polymers has done worse than the NIFTY 500 by 11% over the last 52 weeks. Over 13 weeks the gap is a shortfall of 3.2%. Manali Petrochemicals Ltd is the strongest against the sector itself at +14.6%.

Petrochem - Polymers has done worse than the NIFTY 500 by 11% over 52 weeks and by 3.2% over 13 weeks. 0 of 7 companies we track are beating the NIFTY on relative strength (how a share price has done against the index over recent months), and 3 of the 6 with a long enough price history are ahead of the industry itself.

A score that ranks each company against the others in its industry. The four parts shown always add up to the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or old evidence affects only its own part, never as a hidden adjustment.

Bhansali Engineering Polymers Ltd has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 93% evidence confidence.

Kothari Petrochemicals Ltd scores well on valuation against its peers or its own history, but its earnings have not yet improved enough to back that up.

Bhansali Engineering Polymers Ltd has the strongest one-year price move in Petrochem - Polymers at +7.9%. Manali Petrochemicals Ltd leads on relative strength against the NIFTY, at +13.0%. 3 of 7 companies we track are ahead of the index on that measure. Every line covers 313 weekly closes through 30 October 2026.

Price and relative strength

Price · same starting point: Every company, the sector's own index and NIFTY 500 all start level on the left edge of the window, so only the distance between the lines counts: the highest line has risen the most since then, and the chart at the top of this page is drawn the same way. It opens on one year; the buttons beside it stretch that to three or five.

RS vs NIFTY 500: How far ahead of or behind NIFTY 500 each company has been running, measured against its own recent average of that comparison, so the flat line at zero IS NIFTY 500: above it the company is beating the market, below it the market is beating the company. It opens on one year.

RS vs sector: The same measure taken against Petrochem - Polymers itself instead of the whole market, so the flat line at zero is the sector: above it the company is beating its own peers, which is the sharper test of the two. It opens on one year.

This is the written read behind the Petrochem - Polymers figures above: what is actually happening in the industry, in words, with the evidence each claim rests on. It is dated 19 Apr 2026, so the words are older than the numbers. 5 themes are live here, 3 of them rated high severity.

The sector is in a transitional phase, battling severe cyclical headwinds through structural pivots. While base commodity chemicals suffer from dumping and margin compression, players shifting toward value-added products and niche capacities are thriving.

The Petrochem - Polymers sector is navigating a highly volatile environment characterized by severe pricing pressure, import dumping, and sluggish top-line growth. Demand signals are fragmented, with KOTHARIPET reporting weak demand, NOCIL seeing mixed signals, and CHEMPLASTS noting an improving trend post a challenging quarter.

How old this read is: OLD: this read comes from our Petrochem - Polymers sector brief dated 19 Apr 2026, about 7 months ago. The page says so rather than dressing it up, and a fresh sector dive replaces it the day it runs.

Supreme Petrochem Ltd has the highest Revenue among the 7 Petrochem - Polymers companies compared here, at ₹6,502 crore. Chemplast Sanmar Ltd is next at ₹4,249 crore. The same company also has the highest Revenue growth, at 19.7%. 7 of 7 companies report a comparable reading, the latest through Sep 2026.

What the numbers say: Supreme Petrochem Ltd is the largest at ₹6,502 crore, 53% ahead of Chemplast Sanmar Ltd. Supreme Petrochem Ltd's growth is 19.7% from a ₹6,502 crore base, with 20 reported quarters out of the last 20. Fast growth from a smaller base is not yet the same as proven size.

What this means: Supreme Petrochem Ltd is both the largest and the fastest-growing company here; the growth has to turn into margin and returns before it counts as more than a fast start.

This conclusion weakens if: Supreme Petrochem Ltd's revenue growth slows for two consecutive comparable reports while its operating margin also compresses.

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

All-company data · latest reported quarter

In every all-company table on this page, each figure is the company’s latest single reported quarter. The rankings above them use trailing-twelve-month or current-market values, so a company can legitimately show a different number in each.

Revenue shows both size and speed. A large company can absorb shocks and pay for wide distribution; faster growth can mean market-share gains, new capacity or stronger demand. The best sign is usually growth that lasts without hurting margins and returns.

Manali Petrochemicals Ltd has the highest OPM among the 7 Petrochem - Polymers companies compared here, at 30%. Bhansali Engineering Polymers Ltd is next at 20%. The same company also has the highest Margin change, at +20 percentage points. 7 of 7 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Manali Petrochemicals Ltd leads both opm at 30% and margin change at +20 percentage points.

What this means: Manali Petrochemicals Ltd sets the level to compare against; the company improving fastest needs another report to confirm the change.

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

Operating margin compares operating profit with revenue. Improvement is measured in percentage points, not percentage growth.

Supreme Petrochem Ltd has the highest Net profit among the 7 Petrochem - Polymers companies compared here, at ₹529 crore. Styrenix Performance Materials Ltd is next at ₹250 crore. Manali Petrochemicals Ltd has the highest Profit growth at the 100% top of the scoring scale, so level and change sit with different companies.

What the numbers say: Supreme Petrochem Ltd earns the most, ₹529 crore of profit over the last 12 months, 111.6% above Styrenix Performance Materials Ltd. Manali Petrochemicals Ltd shows at least 100% on the scoring scale (496.7% in full) growth from a profit base of ₹179 crore. A fast rate from a small base matters less than a large profit that keeps coming.

What this means: Supreme Petrochem Ltd sets the level to compare against; the company improving fastest needs another report to confirm the change.

This conclusion weakens if: The next two comparable reports reverse the current profit growth signal.

Net profit is the residual after operating costs, interest and tax. Growth off a loss or near-zero base is excluded from the fastest-grower rank.

Kothari Petrochemicals Ltd has the highest ROCE among the 7 Petrochem - Polymers companies compared here, at 28.6%. Bhansali Engineering Polymers Ltd is next at 23.8%. Manali Petrochemicals Ltd has the highest ROCE change at +12.9 percentage points, so level and change sit with different companies. 7 of 7 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Kothari Petrochemicals Ltd leads ROCE at 28.6%, 4.8 percentage points above Bhansali Engineering Polymers Ltd. A high return reported once may be one good year; a high return reported year after year shows a lasting business.

What this means: Kothari Petrochemicals Ltd sets the level to compare against; the company improving fastest needs another report to confirm the change.

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

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.

Styrenix Performance Materials Ltd has the lowest PEG among the 7 Petrochem - Polymers companies compared here, at 0.6×. Supreme Petrochem Ltd is next at 0.82×. Kothari Petrochemicals Ltd has the lowest P/E at 8.9×, so level and change sit with different companies. 6 of 7 companies report a comparable reading, the latest through Sep 2026.

What the numbers say: Styrenix Performance Materials Ltd has the lowest comparable PEG at 0.6×, 26.8% below Supreme Petrochem Ltd. That would need today's multiple, the company's own history and steady growth to agree.

What this means: A low valuation is a reason to look closer at the business, not a conclusion on its own.

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

PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is worked out the same way every time, as the P/E on the last 12 months of reported earnings divided by that growth rate, never on expected earnings. 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.

Petrochem - Polymers companies show up on 7 of our India lists. The most are on the dividend stocks list (3 companies).

This Petrochem - Polymers comparison names 4 specific ways its own evidence can mislead, all listed below. All 7 companies here report on comparable dates, so no rank carries a stale marker. A high growth rate can still come from a very small starting figure.

Keep these limits visible

• A high growth rate can come from a very small starting figure. The page keeps level and change separate for that reason.
• A high ROCE can be temporary, or look high because the capital base is small. It is best read beside margin, cash flow and how much is spent back on the business.
• The 4-Factor Sector Score ranks published data only. Management quality, upcoming events and risks are not part of it.
• An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.

This comparison is built from the reported filings of 7 Petrochem - Polymers companies, normalized to a common ₹ scale and a shared quarter axis of up to 20 quarters each. Fundamentals run through Sep 2026 and market data through 30 October 2026.

Every company's second-feed figures reconcile against the primary source on overlapping reported periods, so nothing here is unverified or withheld.

These 24 answers restate the Petrochem - Polymers comparison above in question form. Every one is computed from the same 7 companies and the same reported filings as the rankings and charts, current through Sep 2026. Price and relative-strength answers run through 30 October 2026. Nothing here is estimated, and none of it is a recommendation.
