+------------------------------------------------------------------------------------+

The release represents the first time an Indian stock exchange has provided an ad-free, institutional-grade equity screening utility directly to the public without requiring a broker intermediary or paid subscription.

Core Features & Built-in Investment Screens

Market Lens is organized into two primary screening modes: Pre-Configured Quantitative Screens and the Custom Parameter Matrix.

1. Pre-Configured Strategy Templates

To serve investors without deep financial modeling backgrounds, the exchange built five quantitative screening templates:

  • Growth at a Discount: Filters companies with three-year compounded profit growth exceeding 15% where the current Price-to-Earnings (P/E) ratio trades below the 5-year historical median or sector average.
  • High Dividend Yield Leaders: Surfaces profitable companies offering dividend yields above 3.5% with dividend payout ratios sustainably under 65% of net profit.
  • Capital Discipline & Zero-Debt: Screens for non-financial corporations with a Debt-to-Equity (D/E) ratio under 0.1, Return on Capital Employed (ROCE) greater than 20%, and positive free cash flow over consecutive fiscal years.
  • 52-Week Breakout Watch: Pinpoints equities trading within 3% of their 52-week high backed by daily delivery volumes greater than their 30-day moving average.
  • Value Contrarian: Identifies companies trading below their book value (P/B < 1.0) with positive Return on Equity (ROE) and no promoter pledge holdings.
+------------------------------------------------------------------------------------+
|                  SAMPLE SCREEN: "GROWTH AT A DISCOUNT" (LOGIC)                     |
+------------------------------------------------------------------------------------+
|                                                                                    |
|  Rule 1: Market Capitalization >= ₹5,000 Crore (Midcap & Largecap)                |
|  Rule 2: 3-Year PAT CAGR >= 15.0%                                                  |
|  Rule 3: Current Trailing P/E <= Sector Median P/E                                 |
|  Rule 4: Return on Equity (ROE) >= 18.0%                                           |
|  Rule 5: Promoter Pledging == 0.0%                                                 |
|                                                                                    |
|  Data Source: NSE XBRL Regulatory Filings (Updated at Filing Submission)           |
+------------------------------------------------------------------------------------+

2. Custom Filter Matrix

For experienced market participants, the custom screener exposes over 45 fundamental, structural, and technical data fields:

Category Available Ratios & Metrics Update Frequency
Valuation Trailing P/E, Forward P/E, Price to Book (P/B), EV/EBITDA, Market Cap End of Trading Day
Profitability Return on Equity (ROE), ROCE, Operating Margin (OPM), Net Margin Quarterly (Per XBRL Filing)
Capital Structure Debt to Equity, Interest Coverage Ratio, Current Ratio, Quick Ratio Audited Annual / Semi-Annual
Cash Flows Operating Cash Flow (CFO), Free Cash Flow (FCF), FCF/Net Profit Annual Filings
Ownership FII Holding %, DII Holding %, Promoter Holding %, Promoter Pledge % Quarterly SEBI Submissions
Trading Activity Delivery Volume %, 200-DMA Divergence, 52-Week Range, Beta Continuous (Trade Day Closing)

Technical Edge: Direct-From-Exchange Data Feeds

The technical advantage of Market Lens lies in its data pipeline.

Commercial stock screeners in India (such as Screener.in, Trendlyne, Tijori Finance, and TradingView) rely on third-party data aggregators or automated scraping engines that parse corporate announcements posted to exchange websites. This workflow introduces latency and occasional parsing errors when companies report non-standard corporate actions.

+------------------------------------------------------------------------------------+

Because Market Lens is hosted inside the National Stock Exchange’s primary infrastructure, financial ratios compute directly against the exchange’s NEAPS (NSE Electronic Application Processing System) and verified corporate databases. When a company files its quarterly financial results or board resolutions, the balance sheet items update in Market Lens upon formal regulatory acceptance.

How Market Lens Compares to Screener.in & Trendlyne

While traders commended NSE for delivering an ad-free exchange tool, community discussions across social platforms and trading groups contrasted Market Lens with existing third-party screeners:

Platform Comparison Matrix

Feature / Capability NSE Market Lens (Beta) Screener.in Trendlyne
Subscription Cost 100% Free (No Tiering) Free tier; ₹4,000/yr Premium Free tier; ₹1,188–₹5,988/yr
Advertisements / Trackers None Minimal (Clean UI) Present on free tier
Data Provenance Primary Exchange Feed Aggregated filings Aggregated filings
Custom Query Formulas Slider & Range Selectors Custom Python-like syntax Visual rule builder
Historical Financial Statements 3 to 5 Years 10+ Years 10+ Years
Export to Excel / CSV In development (Beta) Native CSV / Custom Excel Available
Concall Audio & Transcripts Not available Integrated on company page Integrated
Portfolio Sync & Watchlists Basic browser local storage Cloud user accounts Cloud user accounts

Market Lens excels in immediate, authenticated ratio queries and rapid sector sweeps without requiring user logins. Conversely, power investors who rely on complex mathematical formula modeling (e.g. Net Profit > 1.2 * 3Years Average Net Profit) and transcripts continue to use established dedicated platforms.

Strategic Context: The ₹22,569 Crore NSE IPO

The public release of Market Lens arrives at a historic moment for India's capital markets.

The NSE Initial Public Offering (IPO)—one of the largest public share sales in Asian capital markets history with a deal value of ₹22,569 crore—closed its subscription window on September 21, 2026. The offering, consisting entirely of an Offer for Sale (OFS) by existing institutional shareholders including LIC, State Bank of India, and global venture funds, commanded strong demand across institutional and retail tranches.

Key Facts: NSE Public Offering (September 2026)
-----------------------------------------------
Issue Size:             ₹22,569 Crore ($2.7 Billion USD)
Structure:              100% Offer for Sale (OFS)
Bidding Window:         September 17, 2026 – September 21, 2026
Implied Valuation:      Exceeding ₹2.1 Lakh Crore ($25 Billion USD)
Registered Investors:   104 Million+ Unique Demat Accounts in India
Daily Cash Turnover:    ₹95,000+ Crore average daily trading volume

By launching Market Lens during the IPO period, NSE demonstrated that it is expanding its product surface beyond core clearing and matching engines into customer-facing investor tools. Providing free screening infrastructure serves to:

  1. Encourage Informed Retail Participation: Reducing reliance on informal social media tips by providing official screening tools.
  2. Increase Equity Liquidity: Directing retail order flow toward fundamentally sound midcap and smallcap securities with low coverage.
  3. Showcase Digital Infrastructure: Proving the capability of the exchange’s in-house software teams ahead of its public debut.
