Stock Screener Guide 2026: How to Shortlist Quality Indian Stocks in Minutes, With a Live Example

A stock screener does in seconds what used to take an evening with annual reports and a spreadsheet. India has more than 5,000 listed companies across NSE and BSE, and no investor can read all of them. The right set of filters removes 99% of that universe and leaves the handful worth your time.

This guide explains how to use a stock screener step by step, which filters matter for long-term investing and for trading, five ready-made screens you can copy, and the mistakes that turn a good screen into a value trap. It also walks through a live screen run on 6 October 2026, with the actual results.

What Is a Stock Screener and How Does It Work?

A stock screener is a search tool that applies conditions to a database of listed stocks and returns only the companies that meet all of them. You might ask for large caps with return on equity above 20%, or midcaps trading above their 50-day moving average, and the tool checks every company against each rule in a fraction of a second.

Behind the scenes, the screener pulls price data from the exchanges and financial data from company filings, then calculates ratios such as PE, ROE and debt-to-equity. Price-based numbers refresh through the trading day, while fundamental numbers change when a company reports quarterly results. That difference matters, because a ratio based on stale results can mislead you for weeks.

Fundamental vs Technical Filters in a Stock Screener

Every filter answers one question. Fundamental filters ask whether the business is good and fairly priced, while technical filters ask whether the price trend supports buying now. The table lists the filters most Indian investors use and common starting thresholds.

Filter	Type	What It Tells You	Common Starting Threshold
PE ratio	Fundamental	Price paid for each rupee of earnings	Below industry PE
Return on equity (ROE)	Fundamental	Profit generated on shareholder capital	Above 15% to 20%
Debt-to-equity	Fundamental	How much the company borrows	Below 0.5 (not for banks)
Sales and profit growth	Fundamental	Whether the business is expanding	Above 10% a year over 3 years
Market capitalisation	Both	Company size and liquidity	Large, mid or small cap band
50-day moving average	Technical	Intermediate price trend	Price above the average
RSI (14)	Technical	Momentum and overbought or oversold levels	Between 50 and 70 for uptrends
Volume	Technical	Strength of participation	Above the weekly average

Long-term investors doing fundamental analysis lean on the fundamental rows, while traders build screens from the technical rows. The strongest shortlists often use one or two filters from each group.

How to Use a Stock Screener in 6 Steps

The process below works on any free stock screener and keeps you from drowning in either too many or too few results.

1. Decide the goal first: long-term investing, dividend income or short-term trading.
2. Set a market capitalisation band to control liquidity and risk.
3. Add two quality filters, such as ROE above 20% and debt-to-equity below 0.5.
4. Add one valuation filter, such as PE below 30 or below the industry average.
5. Sort the results and cut the list to 10 to 15 names you can study properly.
6. Read the latest results, shareholding pattern and sector outlook for each shortlisted stock.

Live Stock Screener Example: A Quality-at-Fair-Value Screen on 6 October 2026

This screen used three conditions on large-cap stocks: return on equity above 20%, debt-to-equity below 0.5 and a PE ratio below 30. Out of the full large-cap universe, 11 companies matched. Seven of them are shown below, sorted by ROE.

Company	PE Ratio	ROE	Debt-to-Equity	Market Cap (Rs Cr)
Hindustan Zinc	13.90	61.13%	0.39	2,37,294
Tata Consultancy Services	15.24	45.89%	0.11	7,62,819
Infosys	13.64	33.24%	0.10	4,13,741
ITC	16.67	28.53%	0.03	3,36,507
Hero MotoCorp	18.53	26.57%	0.04	1,01,672
Coal India	8.40	26.11%	0.12	2,61,916
HCL Technologies	18.68	22.14%	0.07	3,25,640

Source: NSE and company filings, data as of 6 October 2026. The full result also included HUL, LIC and LTM. LIC was set aside in this table because insurers need different metrics, as explained in the mistakes section below.

Three patterns stand out. Three of the seven names are IT services companies, and Tata Consultancy Services at a PE of 15.24 and Infosys at 13.64 show how far the sector's valuations have cooled, a trend you can track through the Nifty IT index. Hindustan Zinc posts the highest ROE at 61.13%, but metal earnings move with commodity prices, so a high ROE in a strong year may not repeat. Coal India has the lowest PE in the table at 8.40, which looks attractive until you account for its cyclical earnings and the long-term pressure on coal.

Coal India also shows why one screen is never enough. On the same day it passed this fundamental screen, it failed the trend filter used for our list of swing trading stocks to watch in October 2026, because it traded below its 20-day and 50-day averages. A good business and a good entry point are two different questions.

5 Ready-Made Stock Screener Setups for Indian Investors

These five templates cover the most common goals. Use them as starting points and tighten the numbers to match your own risk appetite.

• Quality compounders: ROE above 20%, debt-to-equity below 0.3, profit growth above 15% a year over 3 years.
• Value with safety: PE below industry PE, price-to-book below 3, debt-to-equity below 0.5, positive operating cash flow.
• Dividend income: dividend yield above 3%, payout ratio below 70%, five years of consistent dividends.

• Large-cap stability: market capitalisation above Rs 1,00,000 crore, ROE above 15%, member of the Nifty 50.

Common Mistakes When Using a Free Stock Screener

Most screening errors come from trusting a single number. Watch for these five.

• Falling for a value trap: A very low PE often means the market expects earnings to drop. Check the earnings trend before calling a stock a bargain.
• Using the wrong ratios for financials: Debt-to-equity means little for banks, NBFCs and insurers. Screen lenders on ROA, NIM and gross NPA instead.
• Ignoring data freshness: Fundamental ratios update only after quarterly results. During results season, a ratio may still reflect the previous quarter.
• Over-filtering: Ten strict filters can return zero stocks. Start with three or four and add more only if the list is too long.
• Treating the list as a buy list: A screener ranks numbers. It cannot judge management quality, governance or the next regulatory change.

Frequently Asked Questions

What is a stock screener?

Ans. A stock screener is a tool that filters the listed universe of stocks by conditions you set, such as PE ratio, return on equity, debt-to-equity, market capitalisation or RSI. It turns thousands of companies into a short list that you can research in detail, saving hours of manual checking.

Which is the best stock screener in India?

Ans. The best stock screener in India is one that covers both NSE and BSE, updates data daily, offers fundamental and technical filters together, and lets you save screens. The Univest screener covers more than 5,000 Indian stocks with over 100 filters and is free for registered users.

Is there a free stock screener for Indian stocks?

Ans. Yes. Several platforms offer a free stock screener for Indian stocks, including the Univest screener, which is free for registered users. Free versions usually cover standard filters such as PE, ROE, debt and market cap, while some advanced or custom formula filters may sit behind a paid plan.

How do you use a stock screener for long-term investing?

Ans. Start with a market capitalisation filter, then add quality filters such as ROE above 15 to 20 percent and debt-to-equity below 0.5, and a valuation filter such as PE below the industry average. Read the annual report and recent results of every shortlisted company before investing.

Can a stock screener find swing trading stocks?

Ans. Yes. Use technical filters such as price above the 50-day moving average, positive MACD, RSI between 50 and 70 and volume above the weekly average. These conditions shortlist stocks in a short-term uptrend, but each chart still needs a defined stop-loss before any trade.

Why can a low PE stock be a bad investment?

Ans. A low PE can signal a value trap, where earnings are about to fall, the business is cyclical or the company faces governance or regulatory issues. Compare PE with the stock's own history and its industry, and check whether profits are growing before treating a low PE as a bargain.

Do stock screener filters work for banks?

Ans. Standard filters need adjustment for banks and NBFCs. Debt-to-equity is not meaningful for lenders because borrowing is their raw material, so screen banks on return on assets, net interest margin, gross NPA and capital adequacy instead.
