Plain-language meaning
Theme screens list the listings that belong to an investment theme on the selected exchange — for example semiconductors, EV and new-age automotive, railways PSU, defence or rare earths — and rank them by one metric you choose. Membership always comes from one disclosed source per exchange.
Why it is useful #
They give a quick, transparent starting universe for a theme without building a screener from scratch, and say exactly where the membership came from.
Where it appears and the workflow #
Open Scan Center (/screener/library) and pick a theme card; the Screeners page also shows a Popular theme screens row. The exchange follows the market picker. Choose a lens to rank members: revenue growth year on year, percentage above the 52-week low, 1-year change, P/E, return on equity, or free cash flow to profit. The page address keeps the theme and lens so it can be bookmarked. On mobile the themes sit in a collapsible strip at the top of the Screen library.
Calculation or source #
On NSE, most themes use the published Nifty thematic index membership (for example Digital, Manufacturing, Railways PSU, Mobility, EV & new-age automotive). International venues use an exact industry match (Semiconductors, Aerospace & defence, Chemicals). A few themes, such as NSE semiconductors and rare earths, are short curated lists with a review date. Members are ranked by the chosen lens only — there is no basket return or weighting. P/E ranks the lowest positive values first and excludes zero or negative P/E.
Prerequisites, inputs, period and unit #
No sign-in is needed. Five lenses are Free; free cash flow to profit needs Pro. Each row shows its price date, index-based themes show their membership sync date, and curated lists show their review date. Up to 50 rows are shown.
Worked example #
Illustrative only: ranking an NSE theme by 1-year change lists the member with the largest one-year gain first and shows 'Showing 50 of 63'. Members without that metric appear under Not ranked rather than at the bottom with zero.
What high and low mean #
For most lenses a higher value ranks first; for P/E and percentage above the 52-week low the lowest ranks first. Rank order describes the chosen metric only.
Positive, negative and zero #
Lens values keep their sign. Zero is a real value; members without a value are listed separately as not ranked.
Limitations and common mistakes #
A theme is a membership list, not a recommendation, and curated lists are short and reviewed periodically. Ranking by one metric ignores everything else about the company.
Market-specific differences #
Theme sources differ by exchange: Nifty indices on NSE, industry classification elsewhere, and curated lists filtered to the selected exchange's members.
Suggested next steps #
Open one theme on NSE, rank it by return on equity and then by P/E, and note the source and date shown for its membership.
