FinViz Screener

Overview

Translate natural-language stock screening requests into FinViz screener filter codes, build the URL, and open it in Chrome. No API key required for public screener; FINVIZ Elite is auto-detected from $FINVIZ_API_KEY for enhanced functionality.

Key Features:

• Natural language → filter code mapping (Japanese + English)
• URL construction with view type and sort order selection
• Elite/Public auto-detection (environment variable or explicit flag)
• Chrome-first browser opening with OS-appropriate fallbacks
• Strict filter validation to prevent URL injection

When to Use This Skill

Explicit Triggers:

• "高配当で成長している小型株を探したい"
• "Find oversold large caps near 52-week lows"
• "テクノロジーセクターの割安株をスクリーニングしたい"
• "Screen for stocks with insider buying"
• "FinVizでブレイクアウト候補を表示して"
• "Show me high-growth small caps on FinViz"

• User asks to find stocks matching specific financial characteristics

When NOT to Use:

• Deep fundamental analysis of a specific stock (use us-stock-analysis)
• Portfolio review with holdings (use portfolio-manager)
• Chart pattern analysis on images (use technical-analyst)
• Earnings-based screening (use earnings-trade-analyzer or pead-screener)

Workflow

Step 1: Load Filter Reference

Read the filter knowledge base:

cat references/finviz_screener_filters.md

Step 2: Interpret User Request

Map the user's natural-language request to FinViz filter codes. Use the Common Concept Mapping table below for quick translation, and reference the full filter list for precise code selection.

Note: For range criteria (e.g., "dividend 3-8%", "P/E between 10 and 20"), use the {from}to{to} range syntax as a single filter token (e.g., fa_div_3to8, fa_pe_10to20) instead of combining separate _o and _u filters.

Step 3: Present Filter Selection

Before executing, present the selected filters in a table for user confirmation:

| Type | Value | Meaning |
|---|---|---|
| Theme | artificialintelligence | Artificial Intelligence |
| Sub-theme | aicloud | AI - Cloud & Infrastructure |
| Filter | cap_small | Small Cap ($300M–$2B) |
| Filter | fa_div_o3 | Dividend Yield > 3% |
| Filter | fa_pe_u20 | P/E < 20 |
| Filter | geo_usa | USA |

View: Overview (v=111)
Mode: Public / Elite (auto-detected)

Ask the user to confirm or adjust before proceeding.

Step 4: Execute Script

Run the screener script to build the URL and open Chrome:

python3 scripts/open_finviz_screener.py \
  --filters "cap_small,fa_div_o3,fa_pe_u20,geo_usa" \
  --view overview

# Theme-only screening (no --filters required)
python3 scripts/open_finviz_screener.py \
  --themes "artificialintelligence,cybersecurity" \
  --url-only

# Theme + sub-theme + filters combined
python3 scripts/open_finviz_screener.py \
  --themes "artificialintelligence" \
  --subthemes "aicloud,aicompute" \
  --filters "cap_midover" \
  --url-only

Script arguments:

• --filters (optional): Comma-separated filter codes. Note: theme_* and subtheme_* tokens are not allowed here — use --themes / --subthemes instead.
• --themes (optional): Comma-separated theme slugs (e.g., artificialintelligence,cybersecurity). Accepts bare slugs or theme_-prefixed values.
• --subthemes (optional): Comma-separated sub-theme slugs (e.g., aicloud,aicompute). Accepts bare slugs or subtheme_-prefixed values.
• --elite: Force Elite mode (auto-detected from $FINVIZ_API_KEY if not set)
• --view: View type — overview, valuation, financial, technical, ownership, performance, custom
• --order: Sort order (e.g., -marketcap, dividendyield, -change)
• --url-only: Print URL without opening browser

At least one of --filters, --themes, or --subthemes must be provided.

Step 5: Report Results

After opening the screener, report:

1. The constructed URL
2. Elite or Public mode used
3. Summary of applied filters
4. Suggested next steps (e.g., "Sort by dividend yield", "Switch to Financial view for detailed ratios")

Usage Recipes

Real-world screening patterns distilled from repeated use. Each recipe includes a starter filter set, recommended view, and tips for iterative refinement.

Recipe 1: High-Dividend Growth Stocks (Kanchi-Style)

Goal: High yield + dividend growth + earnings growth, excluding yield traps.

--filters "fa_div_3to8,fa_sales5years_pos,fa_eps5years_pos,fa_divgrowth_5ypos,fa_payoutratio_u60,geo_usa"
--view financial

Filter Code	Purpose
fa_div_3to8	Yield 3-8% (caps high-yield traps)
fa_sales5years_pos	Positive 5Y revenue growth
fa_eps5years_pos	Positive 5Y EPS growth
fa_divgrowth_5ypos	Positive 5Y dividend growth
fa_payoutratio_u60	Payout ratio < 60% (sustainability)
geo_usa	US-listed stocks

Iterative refinement: Start broad with fa_div_o3 → review results → add fa_div_3to8 to cap yield → add fa_payoutratio_u60 to exclude traps → switch to financial view for payout and growth columns.

Recipe 2: Minervini Trend Template + VCP

Goal: Stocks in a Stage 2 uptrend with volatility contraction (VCP setup).

--filters "ta_sma50_pa,ta_sma200_pa,ta_sma200_sb50,ta_highlow52w_0to25-bhx,ta_perf_26wup,sh_avgvol_o300,cap_midover"
--view technical

Filter Code	Purpose
ta_sma50_pa	Price above 50-day SMA
ta_sma200_pa	Price above 200-day SMA
ta_sma200_sb50	200 SMA below 50 SMA (uptrend)
ta_highlow52w_0to25-bhx	Within 25% of 52W high
ta_perf_26wup	Positive 26-week performance
sh_avgvol_o300	Avg volume > 300K
cap_midover	Mid cap and above

VCP tightening filters (add to narrow): ta_volatility_wo3,ta_highlow20d_b0to5h,sh_relvol_u1 — low weekly volatility, near 20-day high, below-average relative volume (contraction signal).

Recipe 3: Unfairly Sold-Off Growth Stocks

Goal: Fundamentally strong companies with recent sharp declines — potential mean reversion candidates.

--filters "fa_sales5years_o5,fa_eps5years_o10,fa_roe_o15,fa_salesqoq_pos,fa_epsqoq_pos,ta_perf_13wdown,ta_highlow52w_10to30-bhx,cap_large,sh_avgvol_o200"
--view overview

Filter Code	Purpose
fa_sales5years_o5	5Y sales growth > 5%
fa_eps5years_o10	5Y EPS growth > 10%
fa_roe_o15	ROE > 15%
fa_salesqoq_pos	Positive QoQ sales growth
fa_epsqoq_pos	Positive QoQ EPS growth
ta_perf_13wdown	Negative 13-week performance
ta_highlow52w_10to30-bhx	10-30% below 52W high
cap_large	Large cap
sh_avgvol_o200	Avg volume > 200K

After review: Switch to valuation view to check P/E and P/S for entry attractiveness.

Recipe 4: Turnaround Stocks

Goal: Companies with previously declining earnings now showing recovery — bottom-fishing with fundamental confirmation.

--filters "fa_eps5years_neg,fa_epsqoq_pos,fa_salesqoq_pos,ta_highlow52w_b30h,ta_perf_13wup,cap_smallover,sh_avgvol_o200"
--view performance

Filter Code	Purpose
fa_eps5years_neg	Negative 5Y EPS growth (prior decline)
fa_epsqoq_pos	Positive QoQ EPS growth (recovery)
fa_salesqoq_pos	Positive QoQ sales growth (recovery)
ta_highlow52w_b30h	Within 30% of 52W high (not at bottom)
ta_perf_13wup	Positive 13-week performance
cap_smallover	Small cap and above
sh_avgvol_o200	Avg volume > 200K

Recipe 5: Momentum Trade Candidates

Goal: Short-term momentum leaders near 52W highs with increasing volume.

--filters "ta_sma50_pa,ta_sma200_pa,ta_highlow52w_b0to3h,ta_perf_4wup,sh_relvol_o1.5,sh_avgvol_o1000,cap_midover"
--view technical

Filter Code	Purpose
ta_sma50_pa	Price above 50-day SMA
ta_sma200_pa	Price above 200-day SMA
ta_highlow52w_b0to3h	Within 3% of 52W high
ta_perf_4wup	Positive 4-week performance
sh_relvol_o1.5	Relative volume > 1.5x
sh_avgvol_o1000	Avg volume > 1M
cap_midover	Mid cap and above

Recipe 6: Theme Screening (AI + Sub-theme Drill-Down)

Goal: Find mid-cap+ AI stocks focused on cloud infrastructure and compute acceleration.

--themes "artificialintelligence"
--subthemes "aicloud,aicompute"
--filters "cap_midover"
--view overview

Type	Value	Purpose
Theme	artificialintelligence	AI theme universe
Sub-theme	aicloud	Cloud & Infrastructure vertical
Sub-theme	aicompute	Compute & Acceleration vertical
Filter	cap_midover	Mid cap and above

Multi-theme example: --themes "artificialintelligence,cybersecurity" selects stocks tagged with either theme (OR logic via | grouping).

Tips: Iterative Refinement Pattern

Screening works best as a dialogue, not a one-shot query:

1. Start broad — use 3-4 core filters to get an initial result set
2. Review count — if too many results (>100), add tightening filters; if too few (<5), relax constraints
3. Switch views — start with overview for a quick scan, then switch to financial or valuation for deeper inspection
4. Layer in technicals — after confirming fundamental quality, add ta_ filters to time entries
5. Save and iterate — bookmark the URL, then adjust one filter at a time to understand its impact
