Filtering for stochastic %K, Bollinger %B, and RSI's own Bollinger %B all reading upper-side surfaces stocks whose current price and momentum sit in the upper portion of their recent reference frames — a direction-asymmetric configuration the conventional 'overbought' label misreads as predictive.
How to use the screener to read upper-side configurations of price-within-range, price-within-Bollinger-Bands, and RSI-within-its-recent-mean — and why this is not an 'oversold' screen.
What This Article Can and Cannot Show
The screener exposes one technical position interpretation — Price Extreme Position — which reads three upper-side configurations simultaneously. The interpretation does not identify oversold conditions despite the conventional vocabulary the surrounding fields sometimes suggest. All three wired observations are sign-asymmetric: they fire only when the close (or RSI) is in the upper portion of its recent reference frame. Equivalent lower-side configurations score 0–30 on those obs, not 70+, and therefore would not activate the interpretation.
A lower-side / oversold interpretation is not currently wired. Building one requires either an inverse-stochastic observation, an inverse-Bollinger-%B observation, or a rewrite using observations that honestly fire on lower-side configurations. Until that gap is filled, screens that look for stocks at the bottom of their range are outside what this tool can answer.
A second interpretation that some readers may expect here — Drawdown Risk Profile — was deactivated (Wave 47) because it referenced an observation key (ulcer-index) that does not exist in the observation catalog. The interpretation cannot fire under any conditions and is currently inactive.
What Upper-Side Configuration Means Structurally
Each of the three wired observations reads a different facet of where the present price (or RSI) sits within its own recent history. Stochastic %K measures the close's position within the 14-week high-low range. Bollinger %B measures the close's position within the 20-week Bollinger Bands (mean ± 2 standard deviations). RSI's own Bollinger %B applies the same lens to the RSI series itself — where does the current RSI value sit within ±2 standard deviations of its 20-week mean.
The interpretation fires when all three are in their upper portions simultaneously. That is the entire claim: three independent upper-side position readings co-occur. It is not a momentum-direction reading (it does not say price is rising), it is not a mean-reversion forecast (it does not say price is about to fall), and it is not a valuation reading (the formulas know nothing about earnings or book value). It is a structural co-occurrence observation across three position metrics.
The observations are direction-asymmetric in a specific way: their underlying formulas use the upper-side reading directly, mapping high values to high scores. A close near the 14-week low scores around 0–10 on stochastic %K; that low-side configuration cannot push the score above 30 and therefore cannot enter the active set the resolver uses. Building a lower-side equivalent would require either inverse versions of these obs or different obs entirely.
Key Observations
Close Position Within Recent High-Low Range
What it measures: Stochastic %K — where the current close sits within the 14-week high-low range. Score 0 = current close equals the 14-week low; score 100 = current close equals the 14-week high. Direction-asymmetric: fires (70+) only when the close is in the upper portion of the range.
Data source: Weekly closing prices over the trailing 14 weeks, identifying the high and low boundaries and the current close's position between them.
Price Position Within Bollinger Bands
What it measures: Bollinger %B — where the current close sits within the 20-week Bollinger Bands (mean ± 2 standard deviations). Score 0 = current close equals the lower band; score 100 = current close equals the upper band. Direction-asymmetric in the same sense: fires (70+) only on the upper-band side.
Data source: Weekly closing prices over the trailing 20 weeks, with the moving average and standard-deviation bands computed from that window.
RSI Above Its Recent Mean
What it measures: Where the current RSI sits within ±2 standard deviations of its own 20-week mean — Bollinger %B applied to the RSI series rather than to price. Score 0 = RSI at its lower band (well below recent mean); score 100 = RSI at its upper band (well above recent mean). Direction-asymmetric: fires on the upper side of the RSI's own recent reference frame.
Data source: Weekly RSI values over the trailing 20 weeks, with mean and standard-deviation bands computed from that window.
Low Annualized Volatility
What it measures: Annualized realized volatility of weekly returns over the trailing year, mapped inversely so low volatility produces a high score. A high score means weekly returns have been stable; a low score means weekly returns have been wide-swinging.
Data source: Standard deviation of weekly returns over the trailing 52 weeks, annualized.
Operating Cash Flow Relative to Net Income
What it measures: Operating cash flow divided by reported net income for the most recent annual period. A high score means reported earnings are well-backed by cash; a low score means reported earnings exceed cash generation. Single-ratio reading, not a composite.
Data source: Operating cash flow and net income from the most recent annual financial statements.
Revenue Growth Composite
What it measures: A composite reading of revenue growth that combines median annual growth rate, share of positive-year observations, and stability across the lookback window. A high score means revenue has been growing positively and consistently across recent fiscal years.
Data source: Annual revenue from the income statement across the configured number of fiscal years.
Interpretations That Emerge
Price Extreme Position (Upper Side)
Constituent observations: Close Position Within Recent High-Low Range, Price Position Within Bollinger Bands, RSI Above Its Recent Mean
What emerges: Three upper-side position readings co-occur. Stochastic %K shows the current close in the upper portion of the 14-week high-low range, Bollinger %B shows the current close in the upper portion of its 20-week Bollinger Bands, and RSI is above its recent 20-week mean (Bollinger %B applied to the RSI series itself). The configuration describes where price and RSI sit within their respective recent reference frames; it does not claim mean reversion follows.
Limits: All three readings record present position within a recent reference frame; none measures momentum direction, predicts mean reversion, or indicates timing. The conventional 'overbought' framing is predictive; the formulas make no such claim. Prices and RSI can remain in upper portions for extended periods. The legacy interpretation name 'Price Extreme Position' is direction-asymmetric — only the upper extreme is observable from this configuration. A lower-extreme / oversold reading would require different observations.
