1. Data Sources and Update Cadence
Every figure is based on confirmed daily bars (OHLCV) collected from external market-data providers after the close. Intraday quotes and minute bars are not used. Once the U.S. close (16:00 ET) and the Korean close (15:30 KST) are final, the day's bars are fetched and every stock is recomputed.
- Split/dividend back-adjustment: when a split or dividend retroactively adjusts past prices, the stock's entire price history is re-downloaded and unified to the same adjustment basis. This keeps moving averages and RS from being distorted by an adjustment mismatch.
- Timing: it runs automatically right after the close, and on market holidays the previous trading day's data is kept.
2. Stock Universe and Exclusion Criteria
For the metrics to be statistically meaningful, the population must be stable. Trend Screener limits the universe with the following criteria.
- U.S.: common stocks listed on the NYSE, NASDAQ, and AMEX. ETFs, preferred shares, and the like are excluded.
- Korea: KOSPI and KOSDAQ stocks that meet a size and liquidity threshold. So that barely-traded micro-caps don't distort the ranking, only names with a market cap of roughly ₩100 billion or more form the population for RS and industry ranking.
- Under 200 trading days excluded: because the 8 conditions rely on the 200-day moving average, newly listed stocks without enough trend history do not appear in the table.
- Ultra-low-priced stocks excluded: stocks under $1 (or an equivalent level in Korea) are excluded, as their volatility and noise are too high.
3. Computing the Weighted Relative Strength (RS)
Relative Strength (RS) is a momentum measure that converts how strongly a stock moves within the whole market into a percentile rank. Instead of a simple one-year return, it uses a weighted average that puts more weight on recent periods.
R(n) = return of the current close vs. the close n months ago
→ ranked into a percentile against all stocks → RS Rating 1 – 99
With 40% of the total weight on the most recent three months, the stocks that break out first as the market bottoms and rebounds earn high scores. Because RS is a relative rank rather than an absolute return, it can surface strong candidates that "fall less" even in a down market. An RS of 99 means the top 1% by momentum.
4. Trend Template — the 8 Trend Conditions
An 8/8 in the table means a stock passed all 8 conditions of Mark Minervini's Stage 2 uptrend, applied identically to U.S. and Korean stocks.
- Price > 150-day & 200-day MAPrice is above the mid- and long-term moving averages.
- 150-day > 200-day MAThe mid-term average is above the long-term one (proper alignment).
- 200-day MA risingThe long-term trend line has been rising for at least a month.
- 50-day > 150-day & 200-day MAThe short-term average is above the mid- and long-term ones.
- Price > 50-day MAPrice is above the short-term average.
- Price ≥ 52-week low × 1.30At least 30% above the floor.
- Price ≥ 52-week high × 0.75Within 25% of the new high.
- RS Rating ≥ 70Relatively strong versus the market.
Taken together, the eight conditions quantify a single state: the short-, mid-, and long-term moving averages are aligned and rising, price sits near a new high, and the stock is strong relative to the market.
5. Liquidity Filter (Optional)
Liquidity is an optional filter separate from the 8 conditions. Turn it on when you want to see only stocks whose average volume over the last 50 trading days is at least 500,000 shares. It does not affect the pass (8/8) determination itself, so thinly traded but strong-trending names still appear on the default screen.
6. Industry Classification and Industry RS
The Industry Analysis page groups stocks into a two-level classification (sector · industry) and, for each group, combines the market-cap-weighted trend strength of its members with breadth (the share of strong names) into a 1–99 industry RS, then ranks from strongest to weakest — because a trend is most reliable when a strong stock sits inside a strong industry.
7. Defining a Leader
The screener's "Leaders" filter quantifies William O'Neil's "Leader or Laggard" principle, keeping only stocks that meet both of the following at once.
- The stock's RS Rating is 90 or higher.
- Its industry ranks within the top 10 by industry RS.
