Is Trend Screener free? Do I need an account?
Yes — it's entirely free, with no sign-up or login required. The U.S. and Korean screeners, Industry Rankings, and Market Environment pages are all available at no cost.
Is this real-time data?
No. Trend Screener does not provide real-time or intraday quotes. Every figure is computed once a day from confirmed daily closing bars after the market closes. It should not be used to check intraday prices.
How often is the stock list updated?
It is recomputed and refreshed automatically after each trading day's close — from the confirmed daily bars once the U.S. close (16:00 ET) and the Korean close (15:30 KST) are final.
What does "8/8" in the table mean?
It means the stock passed all 8 conditions of Mark Minervini's Trend Template. Only when all eight are met do we treat it as a strong stock in a Stage 2 uptrend. Each condition is laid out on the Methodology page.
What does RS 99 mean?
RS 99 places a stock near the top of this site’s eligible RS universe. Rounding and ties mean it does not represent exactly 1% of the whole market. RS is a percentile rank versus the market (1–99), not an absolute return.
How do I use the "RS" and "Industry" filters together?
Raise the RS floor to 90 (or 80/70/60) and only top-momentum names remain; then check the top-ranked groups in the industry filter — as many as you like at once — and only those industries remain. Together they retain stocks meeting your RS floor within selected industries. This site does not establish that this combination improves future returns or win rates.
Why is the "Volume" filter separate?
Volume (the 50-day average) is an optional filter kept separate from the pass conditions. The default screen shows every strong-trending stock even if thinly traded, and you can set a floor (100K / 500K / 1M / 3M shares in the U.S., 50K / 100K / 300K / 1M in Korea) when you want only actively traded names.
What is the ADR% filter, and why the 3-5% range?
ADR% is the mean high/low ratio over 20 sessions minus one, expressed as a percentage. The 3% / 3.5% / 4% / 4.5% / 5% choices divide the displayed list; they are not recommended returns or validated minimum ranges. ADR does not measure direction, gaps or target-hit probability and does not enter the eight-condition count. See the ADR article for calculations and frozen sample medians.
How is the industry ranking's "Industry Score" calculated?
The Industry Rankings page ranks every industry on one number: the cap-weighted composite return of its members — 0.10×1W + 0.30×1M + 0.40×3M + 0.20×6M (the same windows and weights as a stock's RS, √cap weighted with a 15% single-name cap). That return, converted to a percentile within the day's cross-industry distribution, is the 0–100 Industry Score; the table lines up this week's, 3-week-old and 6-week-old ranks so rotation reads in one row. The four cards on top are sector ranks #1–#4, applying the same formula to the SPDR sector ETFs in the U.S. and to cap-weighted member baskets in Korea. The five-pillar sum used through July 2026 (performance, leadership, breakouts, breadth, setup) correlated 0.90 with performance alone while letting density ratios distort thin groups, so it was dropped from the score — the metrics themselves remain on the detail panel as evidence. The full criteria are on the Methodology page.
Does the screener order industries the same way as the Industry Rankings page?
Yes — same basis. The ordering of the screener's industry filter list (the rank number before each item) follows the same Industry Score (0–100) ranking as the Industry Rankings page, so you can tick the top groups you saw there from the top down. Industry relative strength (industry RS) — a 1–99 measure of a group's relative strength alone — remains a separate auxiliary metric, used only as a fallback when ranking data is unavailable.
What is the score (TSS) on the "Market Environment" page?
TSS (Trend Strength Score) summarizes, in a single 0–100 number, whether the current tape favors trend-following and breakout trading. It sums three pillars — Breadth · Institutional Flow · Index Trend — reading 77+ as a strong trend and below 23 as risk-off (all-neutral inputs score 50). It updates after each market close on the confirmed daily bar.
Are the up/down colors reversed between the U.S. and Korean screens?
Following Korean investor convention, this site uses red for up and blue for down throughout. That's the opposite of U.S. charts (green for up, red for down), so keep it in mind when switching between the two markets.
A newly listed stock isn't showing up.
A stock with fewer than 250 sessions (about a year) since listing has no comparable base, so it stays out of the RS population; with no RS rating it cannot meet the 'RS 70 or above' condition and never reaches the pass list.
Why are some stocks missing?
ETFs and preferred shares are excluded, and in the U.S. anything closing under $1 is dropped. Korea excludes nothing by price or market cap — instead, names under roughly ₩10 billion carry no weight in the cap-weighted industry and sector returns, which is what keeps micro-caps from distorting the ranking.
Are the selected stocks buy recommendations?
No. Trend Screener's results are reference material produced by mechanically applying technical rules — not investment advice or stock recommendations. The final decision and responsibility rest entirely with you.
Where does the data come from?
U.S. listings use Nasdaq Trader; U.S. prices and classifications use Yahoo Finance. Korean listings, prices and market caps use Naver Finance. The methodology page links the sources and documents the calculations.
Does it work on mobile?
Yes. Every page is responsive for mobile screens, and you can scroll the tables horizontally to see all columns.
