Presets and rules
Each preset is the exact CleverScan rule this page runs on the latest published daily session. S&P 500 stocks: Stocks on the S&P 500 reference list captured with the published dataset.
| Preset | What it selects | Rule |
|---|---|---|
| All biotechnology stocks | Every S&P 500 stock classified in the industry “Biotechnology”, ordered by market capitalization. Values come from the latest published daily session. Rows are ordered by market cap (highest first). | securityType = "Stock" and indexMembership contains "SP500" and (industry = "Biotechnology") |
| Above the 200-day | S&P 500 stocks in the industry “Biotechnology” whose close is above the 200-session simple moving average. Rows are ordered by vs sma 200 (highest first). | securityType = "Stock" and indexMembership contains "SP500" and (industry = "Biotechnology" and close > sma200) |
| 1-month gains | S&P 500 stocks in the industry “Biotechnology” whose close is above the close 21 sessions earlier, ranked from the largest gain. Rows are ordered by 1m % (highest first). | securityType = "Stock" and indexMembership contains "SP500" and (industry = "Biotechnology" and perfM1Pct > 0) |
| Within 5% of 52-week high | S&P 500 stocks in the industry “Biotechnology” whose close is within 5% of the highest high of the last 252 sessions. Rows are ordered by vs 52-week high (highest first). | securityType = "Stock" and indexMembership contains "SP500" and (industry = "Biotechnology" and hi52wFromHighPct >= -5) |
Define the cohort before comparing stocks
This rule selects the recorded Biotechnology industry in the S&P 500 population. That population differs from a broad small-cap biotechnology universe. The same label can cover commercial-stage businesses and companies whose research programs dominate their economics.
Ask a business-specific research question
Distinguish marketed revenue from development-stage milestones, and examine financing and partner arrangements. A trial result or approval decision can create a discontinuous price move that a daily average smooths only afterward. Read the company’s current filing before interpreting a technical match.
The four presets answer different questions
The default ranks classified members by company market capitalization. Above the 200-day selects close above SMA 200. One-month gains requires positive price change from 21 trading sessions earlier. Near the 52-week high selects closes within 5% of the highest high over 252 sessions. Each rule prints its classification and conditions in full.
| Observation | Interpretation |
|---|---|
| Close 105, SMA 200 of 100 | Above the average; this is a state, not a crossover. |
| Close 105, close 21 sessions earlier of 100 | One-month price performance is +5%. |
| Close 95, 252-session high of 100 | Distance from the high is −5%, included at the boundary. |
| Large company, negative one-month performance | It can lead the capitalization ranking while failing the gains preset. |
Preserve sector and industry distinctions
A low share price is not a measure of a pipeline’s value. The screen’s index population also prevents treating it as a list of every listed biotechnology company.
Review the session and the full comparison
Membership is the classification captured with the published reference population. It is not a reconstruction of a historical index. All preset rows use the same recorded session, and sorting applies to the full matching population before the display limit. A displayed subset is not a sector index or a cohort-average return.
Use the retained Sector Heatmap · S&P 500 for broader market context. Company-by-company rankings and a weighted sector index answer different questions. Keep a record of the cohort and date when comparing the same screen over time.
A screen lists stocks whose published values meet a rule. It is a starting point for research, not a recommendation. Read the data and methodology notes for how sessions and calculations are defined.
