Three Filters Reduced 500 Symbols to 12 — but Which Filter Did the Work?

Screening pipelines frequently mask which exact condition causes selective attrition. This illustrative case uses teaching counts to explain condition dominance. For fixed AND conditions evaluated on the same data and timeframe, changing their order changes intermediate counts, not the final intersection. The remaining 12 candidates prompt a review question, not a recommendation to buy.

Inspect Stage:
Universe: Illustrative 500-symbol sample

Initial Candidate Universe

Raw liquid US large-cap basket
500 Symbols
01

Filter 1: Liquidity & Volume Floor

50-day average volume > 1,000,000 shares
-16.0% Removed
420 Remaining

Standard liquidity threshold eliminates illiquid issues but preserves 84% of the broad index. Minimal selective differentiation occurred in this phase.

02

Filter 2: Trend Alignment Framework

Heavy Lifter
Price > 50 SMA & 50 SMA > 200 SMA with positive slope
-89.3% Discarded
45 Remaining

Key Observation: This single structural trend rule stripped away 375 of the surviving 420 instruments. It effectively dictated almost the entire output structure.

03

Filter 3: Volatility Contraction Metric

10-day ATR / 50-day ATR ratio < 0.70
-73.3% Narrowed
12 Final Batch

Applied strictly over the pre-filtered 45 symbols, yielding the 12 final observational cases without modifying underlying regime bias.

Critical Analytical Note: The 12 surviving tickers are empirical results of this multi-condition logic funnel, displayed exclusively for quantitative pipeline education. They do not represent financial evaluations or actionable suggestions.
Attrition Allocation

The Heavy Lifting Metric

Filter 1 (Volume) 16.0% Drop
Filter 2 (Trend) 89.3% Drop
Filter 3 (Volatility) 6.6% Drop*

*Measured against the original 500-symbol baseline. Analysts frequently attribute final candidate characteristics to Filter 3, when Filter 2 already selected the entire structural cohort.

Systematic Candidate Reduction

Filtering functions strictly as an exclusionary gate. Discarding emotional reactions ensures only assets satisfying hard mathematical bounds enter subsequent qualitative review stages.

Outcome: Non-discretionary screening clarity

Redundant Parameter Isolation

Stacking collinear momentum oscillators creates false confidence rather than filter confirmation. We document methods to detect and purge identical formula variants.

Outcome: Minimalist indicator independence

Sequence Execution Impacts

Changing which condition runs first alters database computational load and candidate sample viability across multi-step screening engines.

Outcome: Optimized filtering sequence trees
