RS Rating vs RS Line | Two views of relative strength
⚡ Quick answer (Speakable)
RS Rating is usually discussed as a numeric score (e.g. 1–99) summarizing in-market relative performance. An RS Line is a time-series relative chart (often price divided by a benchmark index). This site’s RPS (Relative Price Strength) is a per-window in-market percentile—closer to the numeric-score family. None of these are buy/sell advice.
🤖 Short summary (TL;DR)
Under the word “RS” sit both a rank number and a relative chart line. Mixing them leads to myths like “rising line = high rating” or “same as RPS.” When you cite or record, separate number vs line / market / window / observation date.
⚠️ Method boundaries (read first)
- RPS is a percentile of close-to-close price performance ranked among valid same-market names.
- Example markets: Japan (TSE), US, Hong Kong, China A-shares. Japan coverage is described on-site as 3,700+ TSE listings (valid count varies by data date).
- Display windows: RPS20 / RPS50 / RPS90 / RPS120 / RPS250.
- A research metric for screening and sorting—not a rating, forecast, or investment advice.

1. Two views of relative strength
In growth-stock / CANSLIM write-ups, “RS” often appears in two systems at once:
- RS Rating as a number — “RS 80,” “rating 90,” etc., as a roughly 1–99 score
- RS Line as a chart — a relative line of price versus an index, watched for slope, new highs, or breaks
Both ask “strong versus something else,” but they answer differently: the first is “what rank band now,” the second is “how the path versus a benchmark evolved.”
For the umbrella term and this site’s vocabulary, start with Relative strength (RS) and RPS.
2. RS Rating (number / percentile)
RS Rating / RS Rating is typically described as:
- Cross-sectional comparison inside a market (or universe)
- Output as a score / percentile (e.g. 1–99)
- Sometimes compressed into one weighted score (IBD-style approximations)
Saying “RS Rating = 85” usually means a rank summary—upper-band relative performance under that definition—not “price rose 85%.”

3. RS Line (relative chart)
An RS Line (Relative Strength Line) is a time-series line on a chart. A typical idea (implementations vary by tool):
- Divide (or normalize) the stock’s close by a benchmark index
- Plot the ratio under the price chart
- Visually watch slope, new highs, or breaks
The question is not “what percentile now,” but “how the path versus a chosen benchmark moved.” Change the index and the line changes.
A rising line does not guarantee a high cross-sectional rating/RPS if other names are stronger still. Conversely, a flat absolute price with a falling index can make the relative line look stronger.
4. Table: Rating vs Line vs RPS
| Angle | RS Rating (typical) | RS Line (typical) | RPS Stock RPS |
|---|---|---|---|
| Output | Numeric score / percentile | Time-series chart line | Per-window percentiles (RPS20–250) |
| Main question | What rank band in the universe? | Path versus the benchmark? | What rank band for that window/market? |
| Comparison set | Other names in the universe | Chosen index, etc. | Valid same-market sample |
| Windows | Often blended into one | Seen as full chart history | Shown side by side by window |
| Boundary | Study clue | Visual relative-path observation | Research cross-section. Not trade advice |
5. Bridge to this site’s RPS
Practical split for research notes (not entry instructions):
- Record cross-sectional rank as numbers — RPS20 / 50 / 90 / 120 / 250 for “upper band that day/window?”
- Treat relative path as separate evidence — chart RS lines or price structure in another tool/notebook; don’t equate with RPS.
- Name the window — write “RPS90 high” and “RPS250 also high,” not just “high RS.”
- Don’t mix with RSI — RPS and RSI are different.

6. Frequently asked questions (FAQ)
Are RS Rating and RS Line the same?
No. RS Rating is usually a numeric score (e.g. 1–99) ranking relative performance in a market. An RS Line is a relative chart over time (often price versus an index). Same relative-strength context, different output shapes.
Which is this site’s RPS closer to?
RPS here is a per-window in-market percentile (roughly 1–99) on the same market and date. It is closer to numeric RS Rating / relative-rank family—not an RS Line charting feature.
If the RS Line is rising, is RPS also high?
Not necessarily. The RS Line shows a path versus a chosen benchmark; RPS is a cross-sectional rank across the valid sample. Different benchmarks, windows, or dates can diverge.
Are IBD’s RS Rating and RS Line a package?
Study materials often discuss them together, but calculation and display are separate: rating summarizes cross-sectional rank; the line is a time-series relative chart. This site does not reproduce or guarantee IBD numbers or charts. Details: IBD RS Rating vs RPS.
How do RPS and RSI differ?
RPS is cross-sectional (in-market percentile). RSI (Relative Strength Index) is a time-series oscillator from one name’s up/down moves. An RS Line is yet another construct. See RPS vs RSI.
Is a high RS Rating a buy signal?
No. A high rating or high RPS only describes upper-band relative performance for that market, window, and date. It is not a trade recommendation or a guarantee of future returns.
How should I check this for Japan stocks?
On this site’s Japan RPS rankings you can sort TSE names by period RPS. Check RS-Line-style charts in another tool if needed, and record cross-sectional ranks with RPS—a clear research split.
