Chandan Healthcare Ltd (CHANDAN): -7.8% ## Revenue Scale & Growth Durability What the numbers say: Chandan Healthcare Ltd leads revenue at ₹289 crore; the second comparison lacks enough current evidence. Investor read: Chandan Healthcare Ltd sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

Investor read: Chandan Healthcare Ltd sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

Evidence: Chandan Healthcare Ltd · ₹25 crore | Not enough peers | 2/3 recent comparable periods | 1/1 companies · 7 observations Definition: Net profit is the residual after operating costs, interest and tax.

Chandan Healthcare Ltd has the strongest latest improvement at -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.

This conclusion weakens if: The next two comparable reports reverse the current roce change signal. Evidence: Chandan Healthcare Ltd · 23.1% | Not enough peers | Not enough history | 1/1 companies · 0 observations Definition: ROCE asks how much operating return the business earns on the capital employed.

Chandan Healthcare Ltd (CHANDAN): −6.0 pp ### 11-quarter ROCE history ### 11-quarter ROCE change history ## Valuation Against Growth & Quality What the numbers say: There is not enough comparable evidence to name a reliable peg leader. 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: No comparable leader | Not enough peers | Not enough history | 0/1 companies · 0 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 ### P/E — lowest P/E 1. Chandan Healthcare Ltd (CHANDAN): 23.1 ### 11-quarter PEG history ### 11-quarter P/E history - CHANDAN: Mar 2022 — | Mar 2023 — | Mar 2024 — | Sep 2024 — | Dec 2024 — | Mar 2025 22.2 | Jun 2025 22.9 | Sep 2025 25.6 | Dec 2025 29.2 | Mar 2026 22.0 | Jun 2026 30.9 ## 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. - Thin comparisons: Valuation have fewer than three usable current readings. ## Every company - Chandan Healthcare Ltd (CHANDAN) — market value ₹606 Cr; latest fundamentals Jun 2026 ## Source standing of each company Cross-checked: 0.
