Auto Ancillaries - Engine Parts, equal-weighted, based at 200 NIFTY 500, same base, same start trailing 12-month earnings per share rising falling

Both lines start at 200 in the same week, so the distance between them is the whole 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 rebased to 100 at the start and the sector taking the median — so a price line pulling away from flat bars is a re-rating, not earnings. A bar turns red when that figure is lower than the quarter before. Rules are fixed and applied identically 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 any point to read both values and the gap. This is a description of what the numbers did, not advice.

03 · sector relative strength, before individual stocks

Is Auto Ancillaries - Engine Parts outperforming NIFTY 500?

Auto Ancillaries - Engine Parts has outperformed NIFTY 500 by 35.7% over the last 52 weeks. Over 13 weeks the gap is a lead of 20.6%. 4 of 5 covered companies currently beat NIFTY on Mansfield relative strength, so leadership inside the sector is selective. SPR Auto Technologies Ltd is the strongest against the sector itself at +16.4%.

The central tension: the companies with the most scale are not necessarily the companies creating the most change.

Start with scale. Then earnings trajectory. Then business quality. Only after those three agree should price leadership carry much weight.

4-Factor Sector Score

An additive sector-relative research score. The four displayed point contributions always equal the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or stale evidence is absorbed inside the affected factor, never applied as a hidden adjustment.

Growth & earnings · 35%Capital efficiency · 25%Valuation · 20%Relative strength · 20%
India Nippon Electricals Ltd has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 94% evidence confidence.
Banco Products (India) Ltd looks inexpensive relative to peers or its own history, but its earnings trajectory has not yet earned the valuation signal.
SPR Auto Technologies Ltd has stronger price confirmation than earnings confirmation; that is a research prompt, not permission to chase.
How this score is built, and what the marks mean

Missing observations are not scored as bad. Their missing weight lowers confidence and pulls the final score toward neutral. PEG is not shown when the ratio cannot mean anything: the company must be making a profit, its price-to-earnings must be positive, and its three-year earnings growth must fall between 5% and 60%. Dividing a price multiple by a loss, or by growth measured off a tiny base, produces a number that looks precise and tells you nothing. Under relative strength, one mark per week shows the last 12 weeks: a mark is filled where the company led NIFTY 500 by 5% or more over the 13 weeks ending that week, which is the same test used everywhere on this site. Price stage places the company on the same six-step curve the sector itself is placed on — basing, turning, breaking out, leader, fading, asleep — read from how many weeks running it has led NIFTY 500 and whether that lead is widening or shrinking. It describes where the PRICE stands, not the earnings trajectory and not a recommendation, and it is left blank for a company whose weekly history is too short or too stale to read.

05 · what price has already done

Market action

SPR Auto Technologies Ltd has the strongest one-year price move in Auto Ancillaries - Engine Parts at +81.8%. It also leads on Mansfield relative strength against NIFTY at +38.7%. 4 of 5 covered companies are above zero on that measure. Every line covers 313 weekly closes through 2026-07-31.

Price and relative strength

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.

Revenue Scale & Growth Durability

Sundram Fasteners Ltd has the highest Revenue among the 5 Auto Ancillaries - Engine Parts companies compared here, at ₹6,288 crore. SPR Auto Technologies Ltd is next at ₹4,458 crore. India Nippon Electricals Ltd has the highest Revenue growth at 26.4%, so level and change sit with different companies. Its Revenue series carries 20 reported observations across the 20-quarter window.

What the numbers say: Sundram Fasteners Ltd is the scale leader at ₹6,288 crore, 41% ahead of SPR Auto Technologies Ltd. India Nippon Electricals Ltd's growth is 26.4% from a ₹1,069 crore base, with 20 reported observations in the 20-quarter window. Treat the growth leader as an acceleration candidate, not as equally proven scale.

LeaderSundram Fasteners Ltd · ₹6,288 crore
Gap41% versus #2 · SPR Auto Technologies Ltd
Persistence8/8 recent comparable periods
Coverage5/5 companies · 94 observations

Investor read: Sundram Fasteners Ltd is the scale benchmark; India Nippon Electricals Ltd is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.

This conclusion weakens if: Sundram Fasteners Ltd's growth falls below India Nippon Electricals Ltd's for two consecutive comparable reports while 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.

Investor read: Banco Products (India) 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 margin change signal.

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

Investor read: Sundram Fasteners 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 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.

Return On Capital Employed

Banco Products (India) Ltd has the highest ROCE among the 5 Auto Ancillaries - Engine Parts companies compared here, at 30.9%. SPR Auto Technologies Ltd is next at 20.8%. Triton Valves Ltd has the highest ROCE change at +2 percentage points, so level and change sit with different companies. Its ROCE series carries 15 reported observations across the 20-quarter window.

What the numbers say: Banco Products (India) Ltd leads ROCE at 30.9%, 10.1 percentage points above SPR Auto Technologies Ltd. Triton Valves Ltd has the strongest latest improvement at +2 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: Banco Products (India) 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.

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

Banco Products (India) Ltd has the lowest PEG among the 5 Auto Ancillaries - Engine Parts companies compared here, at 0.28×. India Nippon Electricals Ltd is next at 0.42×. The same company also holds the lowest P/E, at 19.6×. 4 of 5 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: Banco Products (India) Ltd has the lowest comparable PEG at 0.28×, 33.3% below India Nippon Electricals Ltd. Only 4 of 5 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.

LeaderBanco Products (India) Ltd · 0.28×
Gap33.3% versus #2 · India Nippon Electricals Ltd
Persistence0/8 recent comparable periods
Coverage4/5 companies · 41 observations

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.

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?

This Auto Ancillaries - Engine Parts comparison names 4 specific ways its own evidence can mislead, all listed below. All 5 companies here report on comparable dates, so no rank carries a stale marker. A high growth rate can still be a low-base artefact.

Keep these limits visible

  • 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.
12 · evidence and freshness

How was this comparison built?

This comparison is built from the reported filings of 5 Auto Ancillaries - Engine Parts companies, normalized to a common ₹ scale and a shared quarter axis of up to 20 quarters each. Fundamentals run through Mar 2026 and market data through 2026-07-31.

How a second data feed is admitted, and what happens when it disagrees

A second feed is read only after its reported income is matched against the primary source on at least three overlapping periods. Where the two agree the figures fill silently. Where there is too little shared history to compare, the figures are still drawn — they are the only evidence there is — and marked ⚠ unverified everywhere they appear. Where the two are known to disagree, nothing from the second feed is drawn and the affected company is named under the chart it is missing from.

Auto Ancillaries - Engine Parts company comparison FAQs

These 24 answers restate the Auto Ancillaries - Engine Parts 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 Mar 2026. Price and relative-strength answers run through 2026-07-31. Nothing here is estimated, and none of it is a recommendation.

Auto Ancillaries - Engine Parts has outperformed NIFTY 500 by 35.7% over 52 weeks and 20.6% over 13 weeks. 4 of 5 covered companies beat NIFTY on Mansfield relative strength, while 2 of 5 beat the sector itself.

Which Auto Ancillaries - Engine Parts company has the strongest 4-Factor Sector Score?

Banco Products (India) Ltd has the lowest comparable PEG at 0.28, among 4 of 5 companies whose earnings and growth are steady enough for the ratio to mean anything.

How much history does this Auto Ancillaries - Engine Parts comparison include?

The page compares up to 20 reported quarters per company for fundamentals, returns and valuation, ending Mar 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 Auto Ancillaries - Engine Parts index?

The Nifty Auto Ancillaries - Engine Parts index tracks India's listed Auto Ancillaries - Engine Parts companies as a single basket. This page follows the same 5 companies and equal-weights them, so every company's weekly return counts once whatever it is worth, and the reading belongs to the Auto Ancillaries - Engine Parts sector rather than to its largest constituent. Figures are as of Mar 2026.

Which are the best Auto Ancillaries - Engine Parts stocks in India?

Ranked by this page's four-factor score, India Nippon Electricals Ltd places first among 5 listed Auto Ancillaries - Engine Parts companies, followed by Banco Products (India) Ltd. That is a ranking of published data — earnings, quality, valuation and market behaviour as of Mar 2026 — and not a recommendation; Sector Alpha is not registered with SEBI as an investment adviser.

How many Auto Ancillaries - Engine Parts stocks are listed in India?

This comparison covers 5 listed Auto Ancillaries - Engine Parts 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 Mar 2026.

Which Auto Ancillaries - Engine Parts company is the biggest?

Sundram Fasteners Ltd is the largest, with trailing-twelve-month revenue of ₹6,288 crore, ahead of SPR Auto Technologies Ltd at ₹4,458 crore. That covers 5 of 5 companies with comparable reporting through Mar 2026.

Which Auto Ancillaries - Engine Parts company has the best profit margins?

Banco Products (India) Ltd has the highest operating margin at 20%, from 5 of 5 comparable companies. Triton Valves Ltd shows the biggest recent improvement, at +1.6 percentage points. A high margin matters most when it is holding or rising, not when it is peaking.

Which Auto Ancillaries - Engine Parts company makes the most profit?

Sundram Fasteners Ltd earns the most, at ₹593 crore of trailing-twelve-month net profit, from 5 of 5 comparable companies. Triton Valves Ltd has the fastest profit growth at 89.8%, though growth off a small or recovering profit base overstates how much has actually changed.

Which Auto Ancillaries - Engine Parts company earns the highest return on capital?

Banco Products (India) Ltd leads on return on capital employed at 30.9%, across 5 of 5 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 Auto Ancillaries - Engine Parts stock is the cheapest?

On PEG — where a LOWER number is cheaper — Banco Products (India) Ltd screens cheapest at 0.28×. Only 4 of 5 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 Auto Ancillaries - Engine Parts sector beating the market?

Auto Ancillaries - Engine Parts has outperformed NIFTY 500 by 35.7% over the last 52 weeks and 20.6% over 13 weeks, measured on an equal-weight index of its current members. Inside the sector, 4 of 5 covered companies are beating the market on their own. Sector strength does not transfer evenly to every stock in it.

Which Auto Ancillaries - Engine Parts stock has the strongest price momentum?

SPR Auto Technologies 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 Auto Ancillaries - Engine Parts company scores highest for research priority?

India Nippon Electricals Ltd scores 61.7 out of 100 with 94% evidence confidence, from 27.2 points on growth and earnings, 11 on capital efficiency, 13.4 on valuation and 10.1 on relative strength.
