How to read RPS20/50/90/120/250 | Multi-period resonance (research filter)
⚡ Quick answer (Speakable)
On this site, RPS is a per-window in-market percentile (roughly 1–99) on the same market and observation date. RPS20, 50, 90, 120, and 250 differ only by window length—higher means “relatively high in that window.” When several windows sit in the upper band together, research notes may call it resonance—not a buy-signal definition.
🤖 Short summary (TL;DR)
Single-window views miss short spikes or long inertia. In research, record which windows are high, whether they align or diverge, and keep the observation date. Treat volume, liquidity, earnings, and market direction as separate evidence. Vocabulary bridge: RS → RPS.
⚠️ 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.
- “Resonance” and “divergence” are descriptive observation labels—not signal definitions, win-rate claims, or expected-value claims.
- ; revised only when page facts or methodology change.
1. What each window means (RPS20–250)
Core definition: What is RPS?. Here we focus on what changing the window changes.
| Label | Window idea | Research question (descriptive) | Caution |
|---|---|---|---|
| RPS20 | ~20 trading days | Was it relatively strong recently? | Noisier; event reactions show up fast |
| RPS50 | ~50 trading days | Upper band on a shorter medium horizon? | Bridge between short and medium |
| RPS90 | ~90 trading days | Medium-term relative place? | Near a quarterly observation scale |
| RPS120 | ~120 trading days | Upper band over ~half a year? | Common research filter in CANSLIM study notes |
| RPS250 | ~250 trading days | Relatively strong over a longer span? | Older regimes can linger in the print |
“About N months” is a rough trading-day intuition. Prefer methodology / calculation pages for exact day counts and gap handling.
2. How to read the numbers correctly
- Percentile — RPS90 = 85 means “ahead of about 85% of valid names,” not price +85%.
- Market fixed — Japan RPS ranks inside Japan. Don’t mix with US RPS.
- Observation date required — the same ticker can change rank the next day.
- Not RSI — similar names, different formulas. See RPS vs RSI.
3. Resonance and divergence (research notes)
Here, resonance is an observation-note label for several windows sitting in the relative upper band together. It does not claim win rate or expected value.
Example research-note template
- Market: Japan (TSE) / observation date: YYYY-MM-DD
- Ticker and each window’s RPS (20/50/90/120/250)
- Resonance? e.g. “RPS50, 90, and 120 all ≥ 80” (state your own rule)
- Divergence? e.g. “only RPS20 high / RPS250 mid”
- Non-price evidence — liquidity, earnings, sector, market direction (keep separate from RPS)
- Conclusion label — “keep / watch / drop.” Do not write trade orders.
Saying “high RS” without a window is ambiguous. Naming the window closes the gap described in Relative strength (RS) and RPS.
4. Common pattern examples (non-advice)
Examples of how to describe readings—not recommendations, bans, or signal definitions.
| Observed pattern (example) | What you can say (descriptive) | What not to over-claim |
|---|---|---|
| Several medium/long windows (e.g. 90/120/250) in the upper band | On that date, medium/long relative place was on the strong side | “Institutions keep buying” / “the rise will continue” |
| Only RPS20 elevated; long windows mid or lower | Near-term relative momentum stands out | “Must bounce” / “must fade” |
| Long high, short softening | Long relative place remains while the recent window was relatively weaker | “Confirmed buy-the-dip” |
| All windows near mid | Not distinctive in that universe on that day | “Bad stock” / “do not buy” |
5. Vs a single RS Rating
IBD-style RS Rating is often described as compressing several windows into one score. This site places them side by side. Different visibility, not a verdict on which is “correct.” Details: IBD RS Rating vs RPS.
If you study relative strength under CANSLIM’s “L,” read CANSLIM stock screening guide and do not treat RPS as a full substitute.
6. Frequently asked questions (FAQ)
Should I prioritize RPS20 or RPS250?
They answer different questions. RPS20 describes near-term relative momentum; RPS250 describes longer relative place. For research, avoid absolutizing one window—record several. That is not a trading priority order.
What is multi-period resonance?
In this site’s wording, several windows (e.g. RPS20/50/90/120) sitting in the relative upper band together may be labeled “resonance” in an observation note. It is a descriptive label—not a strong trade-signal definition.
What if only the short window is high?
You can describe near-term relative momentum as elevated while longer windows are not yet in the upper band. Multiple interpretations exist (bounce, theme spike, etc.)—keep non-price evidence separate and do not treat it as a standalone trade decision.
If RPS≥80 lines up on several windows, is that a buy?
No. Overlapping upper bands can be a research-filter condition for a candidate list, but they are not an entry instruction or a guarantee of future returns.
How does this relate to IBD’s single RS Rating?
IBD-style write-ups often blend windows into one score; this site shows period percentiles side by side. See IBD RS Rating vs RPS.
Should I compare RPS and RSI by period?
Different purposes. RPS is an in-market cross-sectional rank; RSI is a single-name time-series oscillator. Do not double-count them as the same confirmation. Details: RPS vs RSI.
