## 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.

1. Garden Reach Shipbuilders & Engineers Ltd (GRSE): 67/100 — Favorable setup; evidence 97%
   - Growth & earnings 29.4/35 | Capital efficiency 16.8/25 | Valuation 12.2/20 | Relative strength 8.4/20
   - Price stage: ASLEEP — Neither ahead of the benchmark nor yet turning up against it.
   - Led NIFTY 500 by 5%+ over the prior 13 weeks in 7 of the last 12 weeks
   - Exact sum: 29.4 + 16.8 + 12.2 + 8.4 = 66.8

## Revenue Scale & Growth Durability

What the numbers say: Mazagon Dock Shipbuilders Ltd is the scale leader at ₹13,323 crore, 77.5% ahead of Garden Reach Shipbuilders & Engineers Ltd. Swan Defence and Heavy Industries Ltd's growth is stored at the ≥100% scoring cap; the uncapped TTM change is 3928.6% from a ₹282 crore base, with 14 reported observations in the 20-quarter window.

This conclusion weakens if: Mazagon Dock Shipbuilders Ltd's growth falls below Swan Defence and Heavy Industries Ltd's for two consecutive comparable reports while operating margin also compresses.

What the numbers say: Garden Reach Shipbuilders & Engineers Ltd leads ROCE at 43%, 7 percentage points above Mazagon Dock Shipbuilders Ltd. Garden Reach Shipbuilders & Engineers Ltd has the strongest latest improvement at +9.7 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: Garden Reach Shipbuilders & Engineers 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.

Evidence: Garden Reach Shipbuilders & Engineers Ltd · 43% | 19.4% versus #2 · Mazagon Dock Shipbuilders Ltd | 8/8 recent comparable periods | 4/4 companies · 46 observations

Definition: 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

What the numbers say: Garden Reach Shipbuilders & Engineers Ltd has the lowest comparable PEG at 1×, 53.5% below Mazagon Dock Shipbuilders Ltd. Only 3 of 4 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.

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.

Evidence: Garden Reach Shipbuilders & Engineers Ltd · 1× | 53.5% versus #2 · Mazagon Dock Shipbuilders Ltd | 0/8 recent comparable periods | 3/4 companies · 27 observations

Definition: 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.

### PEG — lowest PEG
1. Garden Reach Shipbuilders & Engineers Ltd (GRSE): 1.0
2. Mazagon Dock Shipbuilders Ltd (MAZDOCK): 2.2
3. Cochin Shipyard Ltd (COCHINSHIP): 8.2

### P/E — lowest P/E

## What can make this comparison misleading?
- 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.
- 1 company is missing from the second-feed metrics by decision, not by absence: the two sources disagree, so nothing from the second is drawn. Read those rows as narrower evidence, never as a weaker business.

### What is the Nifty Ship - Docks/Breaking/Repairs index?

The Nifty Ship - Docks/Breaking/Repairs index tracks India's listed Ship - Docks/Breaking/Repairs companies as a single basket. This page follows the same 4 companies and equal-weights them, so every company's weekly return counts once whatever it is worth, and the reading belongs to the Ship - Docks/Breaking/Repairs sector rather than to its largest constituent. Figures are as of Jun 2026.

Ranked by this page's four-factor score, Garden Reach Shipbuilders & Engineers Ltd places first among 4 listed Ship - Docks/Breaking/Repairs companies, followed by Mazagon Dock Shipbuilders Ltd.

### How many Ship - Docks/Breaking/Repairs stocks are listed in India?

This comparison covers 4 listed Ship - Docks/Breaking/Repairs 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 Jun 2026.

Garden Reach Shipbuilders & Engineers Ltd leads on return on capital employed at 43%, across 4 of 4 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 Ship - Docks/Breaking/Repairs stock is the cheapest?

On PEG — where a LOWER number is cheaper — Garden Reach Shipbuilders & Engineers Ltd screens cheapest at 1×. Only 3 of 4 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.

### Which Ship - Docks/Breaking/Repairs stock has the strongest price momentum?

Swan Defence and Heavy Industries 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.

Garden Reach Shipbuilders & Engineers Ltd scores 66.8 out of 100 with 97% evidence confidence, from 29.4 points on growth and earnings, 16.8 on capital efficiency, 12.2 on valuation and 8.4 on relative strength. This ranks what deserves work next. It is not a buy recommendation, and management quality, catalysts and risk still need separate research.

### How many Ship - Docks/Breaking/Repairs companies does this comparison cover, and over what period?

It compares 4 listed companies over up to 20 reported quarters of fundamentals, ending Jun 2026, plus weekly price and relative-strength history. Membership is the full sector list — nothing is dropped for having thin data.

### What is the total market cap of the Ship - Docks/Breaking/Repairs sector?

The 4 Ship - Docks/Breaking/Repairs companies on this page carry ₹1,76,342 crore of combined market value. Mazagon Dock Shipbuilders Ltd is the largest at ₹96,077 crore, about 54% of the sector's total on its own. Market value moves with price, so this reading is dated 2026-08-05.

### How is the Ship - Docks/Breaking/Repairs sector performing?

### Why are some values on this page blank?

A blank means that company did not report a comparable figure for that period, so nothing is shown. Missing observations are never interpolated, carried forward, or replaced with a similar-looking accounting line, and a company with missing evidence has its research score pulled toward neutral rather than being scored as bad.

### Is this investment advice?

No. Every figure here is a deterministic calculation from reported company filings and market data, published for research. It contains no recommendation to buy or sell any security, does not account for your circumstances, and is not a substitute for advice from a licensed adviser.
