The Auto Ancillaries - Spare Parts Accessories companies below are the listed Indian Auto Ancillaries - Spare Parts Accessories universe this page tracks — the same constituent set people search for as the Nifty Auto Ancillaries - Spare Parts Accessories index.

Auto Ancillaries - Spare Parts Accessories, 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 4 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 - Spare Parts Accessories outperforming NIFTY 500?

Auto Ancillaries - Spare Parts Accessories has outperformed NIFTY 500 by 16.3% over the last 52 weeks. Over 13 weeks the gap is a lead of 5.8%. 3 of 4 covered companies currently beat NIFTY on Mansfield relative strength, so leadership inside the sector is selective. Rico Auto Industries Ltd is the strongest against the sector itself at +24.4%.

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%
Automotive Stampings & Assemblies Ltd has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 84% evidence confidence.
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.

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.

Investor read: Rico Auto Industries Ltd is the scale benchmark; Automotive Stampings & Assemblies Ltd is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.

This conclusion weakens if: Rico Auto Industries Ltd's growth falls below Automotive Stampings & Assemblies 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.

Return On Capital Employed

Automotive Stampings & Assemblies Ltd has the highest ROCE among the 4 Auto Ancillaries - Spare Parts Accessories companies compared here, at 25.3%. IST Ltd is next at 12.7%. The same company also holds the highest ROCE change, at +4.6 percentage points. 4 of 4 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Automotive Stampings & Assemblies Ltd leads ROCE at 25.3%, 12.6 percentage points above IST Ltd. Automotive Stampings & Assemblies Ltd has the strongest latest improvement at +4.6 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.

LeaderAutomotive Stampings & Assemblies Ltd · 25.3%
Gap99.2% versus #2 · IST Ltd

Investor read: Automotive Stampings & Assemblies 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

No company in this Auto Ancillaries - Spare Parts Accessories comparison reports a valuation figure this section can compare, so the PEG rank is empty. On P/E, IST Ltd is lowest at 5.01×, across 4 of 4 companies with a usable reading.

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

LeaderNo comparable leader
GapNot enough peers
PersistenceNot enough history
Coverage0/4 companies · 0 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 - Spare Parts Accessories comparison names 6 specific ways its own evidence can mislead, all listed below. All 4 companies here report on comparable dates, so no rank carries a stale marker. 3 draw at least one figure from a second feed with too little overlap to cross-check.

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.
  • 3 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.
  • Thin comparisons: Valuation have fewer than three usable current readings.

How was this comparison built?

This comparison is built from the reported filings of 4 Auto Ancillaries - Spare Parts Accessories companies, normalized to a common ₹ scale and a shared quarter axis of up to 20 quarters each. Fundamentals run through Jun 2026 and market data through 2026-07-31.

Market dataThrough 2026-07-31 · weekly price and relative-strength history
Derived metricsGrowth, changes and PEG are calculated only when their inputs are comparable.
Score confidenceMissing and stale evidence reduces confidence and pulls the 0–100 research-priority score toward neutral.

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.
