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 38% behind NIFTY 500. Earnings across its companies fell 8% on average over the last four reported quarters. It has been ahead of NIFTY 500 on a rolling three-month view for 4 weeks running.

Price down, no fundamental support. 1 of 3 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 4 weeks running; 1 of the 3 companies in the industry index above their 200-day average (no change from four weeks earlier); 1 of those 3 pass the momentum test (no change from four weeks earlier); earnings rising at 1 of the 3 that report earnings.

Ahead of NIFTY 500 for 4 weeks after being behind, with 1 → 1 of 3 participating. Earnings not confirming, 1 of 3 members have higher trailing twelve-month earnings than a year ago. The largest member is more than half the sector's market value and is moving the other way.

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 3 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.

Infra - Power - Generation/Distribution has done worse than the NIFTY 500 by 34.6% over the last 52 weeks. Over 13 weeks the gap is a lead of 0.9%. Kalpataru Projects International Ltd is the strongest against the sector itself at +27.9%. Readings are as of 30 October 2026.

Relative-strength score for the industry: 9.0 as of 30 October 2026 (consolidation, falling).

Infra - Power - Generation/Distribution has done worse than the NIFTY 500 by 34.6% over 52 weeks, but is 0.9% ahead over the last 13 weeks. 1 of 3 companies we track is beating the NIFTY on relative strength (how a share price has done against the index over recent months), and 2 of the 2 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.

Kalpataru Projects International Ltd has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 75.1% evidence confidence.

Kalpataru Projects International Ltd has the strongest one-year price move in Infra - Power - Generation/Distribution at +6.5%. It also leads on relative strength against the NIFTY, at +11.5%. 1 of 3 companies we track is 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 Infra - Power - Generation/Distribution 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 Infra - Power - Generation/Distribution figures above: what is actually happening in the industry, in words, with the evidence each claim rests on. It is dated 17 Apr 2026, so the words are older than the numbers. 3 themes are live here, 1 of them rated high severity.

The sector outlook is bullish, anchored by KPIL's excellent execution, massive order book, and successful deleveraging. While working capital bottlenecks in the water segment and legacy issues in Brazil pose localized risks, the overarching trajectory of revenue growth and margin expansion remains intact.

The Infra - Power - Generation/Distribution sector, represented this week by Kalpataru Projects International Ltd (KPIL), is demonstrating an IMPROVING demand environment.

How old this read is: OLD: this read comes from our Infra - Power - Generation/Distribution sector brief dated 17 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.

Kalpataru Projects International Ltd has the highest Revenue among the 3 Infra - Power - Generation/Distribution companies compared here, at ₹27,380 crore. Reliance Infrastructure Ltd is next at ₹20,877 crore. The same company also has the highest Revenue growth, at 14.6%. 3 of 3 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Kalpataru Projects International Ltd is the largest at ₹27,380 crore, 31.1% ahead of Reliance Infrastructure Ltd. Kalpataru Projects International Ltd's growth is 14.6% from a ₹27,380 crore base, with 15 reported quarters out of the last 20. Fast growth from a smaller base is not yet the same as proven size.

What this means: Kalpataru Projects International 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: Kalpataru Projects International 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.

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.

GMR Power & Urban Infra Ltd has the highest OPM among the 3 Infra - Power - Generation/Distribution companies compared here, at 23%. Kalpataru Projects International Ltd is next at 9%. The same company also has the highest Margin change, at +4 percentage points. 3 of 3 companies report a comparable reading, the latest through Sep 2026.

What the numbers say: GMR Power & Urban Infra Ltd leads both opm at 23% and margin change at +4 percentage points.

What this means: GMR Power & Urban Infra 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.

Reliance Infrastructure Ltd has the highest Net profit among the 3 Infra - Power - Generation/Distribution companies compared here, at ₹5,300 crore. Kalpataru Projects International Ltd is next at ₹1,129 crore. Kalpataru Projects International Ltd has the highest Profit growth at 61.8%, so level and change sit with different companies.

What the numbers say: Reliance Infrastructure Ltd earns the most, ₹5,300 crore of profit over the last 12 months, 369.4% above Kalpataru Projects International Ltd. A fast rate from a small base matters less than a large profit that keeps coming.

What this means: Reliance Infrastructure 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.

Kalpataru Projects International Ltd has the highest ROCE among the 3 Infra - Power - Generation/Distribution companies compared here, at 18.3%. Reliance Infrastructure Ltd is next at 15.4%. The same company also has the highest ROCE change, at +2 percentage points. 3 of 3 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Kalpataru Projects International Ltd leads ROCE at 18.3%, 2.9 percentage points above Reliance Infrastructure 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: Kalpataru Projects International 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.

Withheld from this chart: Kalpataru Projects International Ltd (KPIL): its two data sources disagree by up to 11% on reported income across 15 comparable periods, so its derived ratios are withheld. A figure two sources cannot agree on is not drawn, the gap is a decision, not missing data.

No company in this Infra - Power - Generation/Distribution comparison reports a valuation figure this section can compare, so the PEG rank is empty. On P/E, Reliance Infrastructure Ltd is lowest at 0.89× at the latest share price, across 2 of 3 companies with a usable reading.

What the numbers say: There is not enough comparable evidence to name a reliable peg leader.

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.

Infra - Power - Generation/Distribution companies show up on 5 of our India lists. The most are on the power & green energy stocks list (3 companies).

This Infra - Power - Generation/Distribution comparison names 6 specific ways its own evidence can mislead, all listed below. All 3 companies here report on comparable dates, so no rank carries a stale marker. 1 has second-source figures left out because the two sources disagree. 1 of the 5 ranked sections has fewer than three usable current readings.

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 is missing from the second-source figures on purpose: the two sources disagree, so nothing from the second is drawn. Those rows have less evidence; that does not make the business weaker.
• Thin comparisons: Valuation have fewer than three usable current readings.

This comparison is built from the reported filings of 3 Infra - Power - Generation/Distribution 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.

1 of 3 companies has a second data feed that is known to disagree with the primary source, so nothing from it is drawn: Kalpataru Projects International Ltd (KPIL): its two data sources disagree by up to 11% on reported income across 15 comparable periods, so its derived ratios are withheld.

These 21 answers restate the Infra - Power - Generation/Distribution comparison above in question form. Every one is computed from the same 3 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.
