All 5 listed Indian Compressors companies are named here, largest first.

Every figure is equal-weighted across those companies and carries its own as-of date.

The line below covers up to 5.1 years and opens on the 5Y view; the buttons cut it shorter. Over the last two years (104 weeks) this sector is 2% ahead of NIFTY 500. Earnings across its companies grew 7% on average over the last four reported quarters, close to flat. It has been ahead of NIFTY 500 on a rolling three-month view for 30 weeks running.

1 of 5 companies pass the momentum test (5+ points ahead of the Nifty 500 over 3 months, within 20% of the 52-week high).

Ahead of NIFTY 500 on the three-month view for 30 weeks running; 2 of the 5 companies in the industry index above their 200-day average (2 fewer than four weeks earlier); 1 of those 5 pass the momentum test (1 fewer than four weeks earlier); earnings rising at 3 of the 5 that report earnings.

Participation is shrinking, 2 → 1 of 5 over four weeks, after being ahead of NIFTY 500. Earnings mixed, 3 of 5 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 5 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.

Compressors has done better than the NIFTY 500 by 33% over the last 52 weeks. Over 13 weeks the gap is a lead of 1.7%. Ingersoll-Rand (India) Ltd is the strongest against the sector itself at −10.4%.

Compressors has done better than the NIFTY 500 by 33% over 52 weeks and by 1.7% over 13 weeks. 0 of 5 companies we track are beating the NIFTY on relative strength (how a share price has done against the index over recent months) (1 has no relative-strength reading yet), and 0 of the 3 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.

Elgi Equipments Ltd has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 95.6% evidence confidence.

Ranked last: too little evidence (1 company)

Under 60% of the evidence behind this score is available, so it ranks after every company above, whatever the score.

Ingersoll-Rand (India) Ltd has the strongest one-year price move in Compressors at +5.4%. Veljan Denison Ltd leads on relative strength against the NIFTY, at +52.8%. 2 of 5 companies we track are ahead of the index on that measure (1 has no relative-strength reading yet). 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 Compressors 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 Compressors figures above: what is actually happening in the industry, in words, with the evidence each claim rests on. It is dated 28 Jul 2026, so the words are older than the numbers. 5 themes are live here, 3 of them rated high severity.

The sector faces headwinds from regulatory costs and mixed demand. While VELJAN demonstrates growth momentum, INGERRAND's revenue contraction and margin compression highlight execution challenges. Capital allocation remains disciplined with KIRLPNU planning Rs. 320 Cr PLI-backed capex.

The compressor sector displays divergent performance trends in Q4 FY26. VELJAN reported consolidated revenue of ₹46.78 crores, marking a 24.2% quarter-on-quarter increase and 10.6% year-on-year growth. In contrast, INGERRAND reported standalone revenue of ₹299.63 crore, declining 7.05% QoQ and 34.22% YoY. KIRLPNU reported total income of Rs.

How old this read is: OLD: this read comes from our Compressors sector brief dated 28 Jul 2026, about 3 months ago. The page says so rather than dressing it up, and a fresh sector dive replaces it the day it runs.

Elgi Equipments Ltd has the highest Revenue among the 5 Compressors companies compared here, at ₹4,146 crore. Kirloskar Pneumatic Company Ltd is next at ₹1,748 crore. The same company also has the highest Revenue growth, at 15.9%. 4 of 5 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Elgi Equipments Ltd is the largest at ₹4,146 crore, 137.2% ahead of Kirloskar Pneumatic Company Ltd. Elgi Equipments Ltd's growth is 15.9% from a ₹4,146 crore base, with 19 reported quarters out of the last 20. Fast growth from a smaller base is not yet the same as proven size.

What this means: Elgi Equipments 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: Elgi Equipments 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.

Veljan Denison Ltd has the highest OPM among the 5 Compressors companies compared here, at 25.7%. Ingersoll-Rand (India) Ltd is next at 24%. Elgi Equipments Ltd has the highest Margin change at +1 percentage points, so level and change sit with different companies. 5 of 5 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Veljan Denison Ltd leads opm at 25.7%; Elgi Equipments Ltd leads margin change at +1 percentage points.

What this means: Veljan Denison 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.

Elgi Equipments Ltd has the highest Net profit among the 5 Compressors companies compared here, at ₹447 crore. Ingersoll-Rand (India) Ltd is next at ₹267 crore. Kirloskar Pneumatic Company Ltd has the highest Profit growth at 39.3%, so level and change sit with different companies. 4 of 5 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Elgi Equipments Ltd earns the most, ₹447 crore of profit over the last 12 months, 67.4% above Ingersoll-Rand (India) Ltd. Kirloskar Pneumatic Company Ltd shows 39.3% growth from a profit base of ₹259 crore. A fast rate from a small base matters less than a large profit that keeps coming.

What this means: Elgi Equipments 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.

Ingersoll-Rand (India) Ltd has the highest ROCE among the 5 Compressors companies compared here, at 57.1%. Kirloskar Pneumatic Company Ltd is next at 29.6%. Kirloskar Pneumatic Company Ltd has the highest ROCE change at +5.2 percentage points, so level and change sit with different companies. 5 of 5 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Ingersoll-Rand (India) Ltd leads ROCE at 57.1%, 27.5 percentage points above Kirloskar Pneumatic Company 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: Ingersoll-Rand (India) 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.

Kirloskar Pneumatic Company Ltd has the lowest PEG among the 5 Compressors companies compared here, at 1.48×. Elgi Equipments Ltd is next at 1.68×. Airfloa Rail Technology Ltd has the lowest P/E at 22×, so level and change sit with different companies. 4 of 5 companies report a comparable reading, the latest through Sep 2026.

What the numbers say: Kirloskar Pneumatic Company Ltd has the lowest comparable PEG at 1.48×, 11.9% below Elgi Equipments 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.

Compressors companies show up on 2 of our India lists. The most are on the small & mid cap stocks list (2 companies).

This Compressors comparison names 5 specific ways its own evidence can mislead, all listed below. 1 of the 5 companies reports on an older date than the sector's freshest reporters, so its rank is marked stale. 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.
• 1 company has an older fundamental reporting date than the sector’s freshest reporters; its rank carries a stale marker.

This comparison is built from the reported filings of 5 Compressors 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 Compressors comparison above in question form. Every one is computed from the same 5 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.
