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 15% behind NIFTY 500. Earnings across its companies grew 16% on average over the last four reported quarters.

0 of 4 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; 0 of the 4 companies in the industry index above their 200-day average (no change from four weeks earlier); 0 of those 4 pass the momentum test (1 fewer than four weeks earlier); earnings rising at 3 of the 4 that report earnings.

Not ahead of NIFTY 500, not building participation, not giving any back. Earnings confirming, 3 of 4 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 4 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.

Auto Ancillaries - Spare Parts Accessories has done better than the NIFTY 500 by 4.7% over 52 weeks, but is 7.2% behind over the last 13 weeks. 0 of 4 companies we track are beating the NIFTY on relative strength (how a share price has done against the index over recent months), and 1 of the 2 with a long enough price history is 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.

Automotive Stampings & Assemblies Ltd has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 87% evidence confidence.

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

Rico Auto Industries Ltd has the strongest one-year price move in Auto Ancillaries - Spare Parts Accessories at +19.0%. India Motor Parts & Accessories Ltd leads on relative strength against the NIFTY, at +0.6%. 1 of 4 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 Auto Ancillaries - Spare Parts Accessories 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.

What is live in this sector right now

Sources: our Auto Ancillaries - Spare Parts Accessories sector brief, 28 Jul 2026.

Rico Auto Industries Ltd has the highest Revenue among the 4 Auto Ancillaries - Spare Parts Accessories companies compared here, at ₹2,689 crore. Automotive Stampings & Assemblies Ltd is next at ₹1,096 crore. Automotive Stampings & Assemblies Ltd has the highest Revenue growth at 42.1%, so level and change sit with different companies.

What the numbers say: Rico Auto Industries Ltd is the largest at ₹2,689 crore, 145.4% ahead of Automotive Stampings & Assemblies Ltd. Automotive Stampings & Assemblies Ltd's growth is 42.1% from a ₹1,096 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: Rico Auto Industries Ltd is the size to compare against; Automotive Stampings & Assemblies Ltd is the one growing fastest. The faster grower has to keep that growth and turn it into margin and returns before it counts as more than a fast start.

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.

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.

IST Ltd has the highest OPM among the 4 Auto Ancillaries - Spare Parts Accessories companies compared here, at 46%. India Motor Parts & Accessories Ltd is next at 8%. India Motor Parts & Accessories Ltd has the highest Margin change at +1 percentage points, so level and change sit with different companies.

What the numbers say: IST Ltd leads opm at 46%; India Motor Parts & Accessories Ltd leads margin change at +1 percentage points.

What this means: IST 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.

IST Ltd has the highest Net profit among the 4 Auto Ancillaries - Spare Parts Accessories companies compared here, at ₹164 crore. India Motor Parts & Accessories Ltd is next at ₹100 crore. Automotive Stampings & Assemblies 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: IST Ltd earns the most, ₹164 crore of profit over the last 12 months, 64% above India Motor Parts & Accessories Ltd. Automotive Stampings & Assemblies Ltd shows at least 100% on the scoring scale (118.8% in full) growth from a profit base of ₹35 crore. A fast rate from a small base matters less than a large profit that keeps coming.

What this means: IST 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.

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 13.1%. The same company also has the highest ROCE change, at +1.6 percentage points. 4 of 4 companies report a comparable reading, the latest through Sep 2026.

What the numbers say: Automotive Stampings & Assemblies Ltd leads ROCE at 25.3%, 12.2 percentage points above IST 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: Automotive Stampings & Assemblies 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.

IST Ltd has the lowest PEG among the 4 Auto Ancillaries - Spare Parts Accessories companies compared here, at 0.52×. India Motor Parts & Accessories Ltd is next at 0.94×. The same company also has the lowest P/E, at 4.27×. 3 of 4 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: IST Ltd has the lowest comparable PEG at 0.52×, 44.7% below India Motor Parts & Accessories 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.

Auto Ancillaries - Spare Parts Accessories companies show up on one of our India lists. The most are on the dividend stocks list (1 company).

This Auto Ancillaries - Spare Parts Accessories comparison names 4 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. 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 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 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 23 answers restate the Auto Ancillaries - Spare Parts Accessories comparison above in question form. Every one is computed from the same 4 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.
