Value Dividend Screener

Overview

This skill identifies high-quality dividend stocks that combine value characteristics, attractive income generation, and consistent growth using a two-stage screening approach:

1. FINVIZ Elite API (Optional but Recommended): Pre-screen stocks with basic criteria (fast, cost-effective)
2. Financial Modeling Prep (FMP) API: Detailed fundamental analysis of candidates

Screen US equities based on quantitative criteria including valuation ratios, dividend metrics, financial health, and profitability. Generate comprehensive reports ranking stocks by composite quality scores with detailed fundamental analysis.

Efficiency Advantage: Using FINVIZ pre-screening can reduce FMP API calls by 90%, making this approach ideal for free-tier API users.

When to Use

Invoke this skill when the user requests:

• "Find high-quality dividend stocks"
• "Screen for value dividend opportunities"
• "Show me stocks with strong dividend growth"
• "Find income stocks trading at reasonable valuations"
• "Screen for sustainable high-yield stocks"
• Any request combining dividend yield, valuation metrics, and fundamental analysis

Workflow

Step 1: Verify API Key Availability

For Two-Stage Screening (Recommended):

Check if both API keys are available:

import os
fmp_api_key = os.environ.get('FMP_API_KEY')
finviz_api_key = os.environ.get('FINVIZ_API_KEY')

If not available, ask user to provide API keys or set environment variables:

export FMP_API_KEY=your_fmp_key_here
export FINVIZ_API_KEY=your_finviz_key_here

For FMP-Only Screening:

Check if FMP API key is available:

import os
api_key = os.environ.get('FMP_API_KEY')

If not available, ask user to provide API key or set environment variable:

export FMP_API_KEY=your_key_here

FINVIZ Elite API Key:

• Requires FINVIZ Elite subscription (~$40/month or ~$330/year)
• Provides access to CSV export of pre-screened results
• Highly recommended for reducing FMP API usage

Provide instructions from references/fmp_api_guide.md if needed.

Step 2: Execute Screening Script

Run the screening script with appropriate parameters:

Two-Stage Screening (RECOMMENDED)

Uses FINVIZ for pre-screening, then FMP for detailed analysis:

Default execution (Top 20 stocks):

python3 scripts/screen_dividend_stocks.py --use-finviz

With explicit API keys:

python3 scripts/screen_dividend_stocks.py --use-finviz \
  --fmp-api-key $FMP_API_KEY \
  --finviz-api-key $FINVIZ_API_KEY

Custom top N:

python3 scripts/screen_dividend_stocks.py --use-finviz --top 50

Custom output location:

python3 scripts/screen_dividend_stocks.py --use-finviz --output /path/to/results.json

Script behavior (Two-Stage):

1. FINVIZ Elite pre-screening:

- Market cap: Mid-cap or higher - Dividend yield: 3%+ - Dividend growth (3Y): 5%+ - EPS growth (3Y): Positive - P/B: Under 2 - P/E: Under 20 - Sales growth (3Y): Positive - Geography: USA

1. FMP detailed analysis of FINVIZ results (typically 20-50 stocks):

- Dividend growth rate calculation (3-year CAGR) - Revenue and EPS trend analysis - Dividend sustainability assessment (payout ratios, FCF coverage) - Financial health metrics (debt-to-equity, current ratio) - Quality scoring (ROE, profit margins)

1. Composite scoring and ranking
2. Output top N stocks to JSON file

Expected runtime (Two-Stage): 2-3 minutes for 30-50 FINVIZ candidates (much faster than FMP-only)

FMP-Only Screening (Original Method)

Uses only FMP Stock Screener API (higher API usage):

Default execution:

python3 scripts/screen_dividend_stocks.py

With explicit API key:

python3 scripts/screen_dividend_stocks.py --fmp-api-key $FMP_API_KEY

Script behavior (FMP-Only):

1. Initial screening using FMP Stock Screener API (dividend yield >=3.0%, P/E <=20, P/B <=2)
2. Detailed analysis of candidates (typically 100-300 stocks):

- Same detailed analysis as two-stage approach

1. Composite scoring and ranking
2. Output top N stocks to JSON file

Expected runtime (FMP-Only): 5-15 minutes for 100-300 candidates (rate limiting applies)

API Usage Comparison:

• Two-Stage: ~50-100 FMP API calls (FINVIZ pre-filters to ~30 stocks)
• FMP-Only: ~500-1500 FMP API calls (analyzes all screener results)

Step 3: Parse and Analyze Results

Read the generated JSON file:

import json

with open('dividend_screener_results.json', 'r') as f:
    data = json.load(f)

metadata = data['metadata']
stocks = data['stocks']

Key data points per stock:

• Basic info: symbol, company_name, sector, market_cap, price
• Valuation: dividend_yield, pe_ratio, pb_ratio
• Growth metrics: dividend_cagr_3y, revenue_cagr_3y, eps_cagr_3y
• Sustainability: payout_ratio, fcf_payout_ratio, dividend_sustainable
• Financial health: debt_to_equity, current_ratio, financially_healthy
• Quality: roe, profit_margin, quality_score
• Overall ranking: composite_score

Step 4: Generate Markdown Report

Create structured markdown report for user with following sections:

Step 5: Provide Context and Methodology

Reference screening methodology when explaining results:

Key concepts to explain:

• Why these specific thresholds (3.5% yield, P/E 20, P/B 2)
• Importance of dividend growth vs. static high yield
• How composite score balances value, growth, and quality
• Dividend sustainability vs. dividend trap distinction
• Financial health metrics significance

Load references/screening_methodology.md to provide detailed explanations of:

• Phase 1: Initial quantitative filters
• Phase 2: Growth quality filters
• Phase 3: Sustainability and quality analysis
• Composite scoring system
• Investment philosophy and limitations

Step 6: Answer Follow-up Questions

Anticipate common user questions:

"Why did [stock] not make the list?"

• Check which criteria it failed (yield, valuation, growth, sustainability)
• Explain the specific filter that excluded it

"Can I screen for specific sectors?"

• Filtering capability exists in script (modify line 383-388)
• Suggest re-running with sector parameter additions

"What if I want higher/lower yield threshold?"

• Script parameters are adjustable
• Trade-offs between yield and growth
• Recommend re-screening with new parameters

"How often should I re-run this screen?"

• Quarterly recommended (aligns with earnings cycles)
• Semi-annually sufficient for long-term holders
• Market conditions may warrant more frequent checks

"How many stocks should I buy?"

• Diversification guidance: minimum 10-15 for dividend portfolio
• Sector balance considerations
• Position sizing based on risk tolerance

Advanced Usage

Customizing Screening Criteria

Modify thresholds in scripts/screen_dividend_stocks.py:

Line 383-388 - Initial screening parameters:

candidates = client.screen_stocks(
    dividend_yield_min=3.5,  # Adjust yield threshold
    pe_max=20,               # Adjust P/E threshold
    pb_max=2,                # Adjust P/B threshold
    market_cap_min=2_000_000_000  # Minimum $2B market cap
)

Line 423 - Dividend CAGR threshold:

if not div_cagr or div_cagr < 5.0:  # Adjust growth threshold

Sector-Specific Screening

Add sector filtering after initial screening:

# Filter for specific sectors
target_sectors = ['Consumer Defensive', 'Utilities', 'Healthcare']
candidates = [s for s in candidates if s.get('sector') in target_sectors]

Excluding REITs and Financials

REITs and financial stocks have different dividend characteristics (higher payouts, different metrics):

# Exclude REITs and Financials
exclude_sectors = ['Real Estate', 'Financial Services']
candidates = [s for s in candidates if s.get('sector') not in exclude_sectors]

Exporting to CSV

Convert JSON results to CSV for Excel analysis:

import json
import csv

with open('dividend_screener_results.json', 'r') as f:
    data = json.load(f)

stocks = data['stocks']

with open('screening_results.csv', 'w', newline='') as csvfile:
    if stocks:
        fieldnames = stocks[0].keys()
        writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
        writer.writeheader()
        writer.writerows(stocks)

Troubleshooting

"ERROR: requests library not found"

Solution: Install requests library

pip install requests

"ERROR: FMP API key required"

Solution: Set environment variable or provide via command-line

export FMP_API_KEY=your_key_here
# OR
python3 scripts/screen_dividend_stocks.py --fmp-api-key your_key_here

"ERROR: FINVIZ API key required when using --use-finviz"

Solution: Set environment variable or provide via command-line

export FINVIZ_API_KEY=your_key_here
# OR
python3 scripts/screen_dividend_stocks.py --use-finviz --finviz-api-key your_key_here

Note: FINVIZ Elite subscription required (~$40/month or ~$330/year)

"ERROR: FINVIZ API authentication failed"

Possible causes:

1. Invalid FINVIZ API key
2. FINVIZ Elite subscription expired
3. API key format incorrect

Solution:

• Verify FINVIZ Elite subscription is active
• Check API key for typos (should be alphanumeric string)
• Log into FINVIZ Elite account and verify API key in settings
• Try accessing FINVIZ Elite screener manually to confirm subscription

"ERROR: FINVIZ pre-screening failed or returned no results"

Possible causes:

1. FINVIZ API connection issue
2. Screening criteria too restrictive (no stocks match)
3. Market conditions (bear market may yield fewer results)

Solution:

• Check internet connection
• Verify FINVIZ Elite website is accessible
• Try FMP-only method as fallback: python3 scripts/screen_dividend_stocks.py

"WARNING: Rate limit exceeded"

Solution: Script automatically retries after 60 seconds. If persistent:

• Wait until next day (free tier resets daily)
• Reduce number of stocks analyzed (modify line 394 limit)
• Consider upgrading to paid FMP tier

"No stocks found matching all criteria"

Solution: Criteria may be too restrictive

• Relax P/E threshold (increase from 20)
• Lower dividend yield requirement (decrease from 3.5%)
• Reduce dividend growth requirement (decrease from 5%)
• Check market conditions (bear markets may have fewer qualifiers)

Script runs slowly

Expected behavior: Script includes 0.3s delay between API calls for rate limiting

• 100 stocks analyzed = ~8-10 minutes
• First 20-30 qualifying stocks usually found within first 50-70 analyzed

Performance & Cost Optimization

API Call Comparison

Two-Stage Screening (FINVIZ + FMP):

• FINVIZ: 1 API call
• FMP Quote API: ~30-50 calls (one per pre-screened symbol)
• FMP Financial Data: ~150-250 calls (5 endpoints × 30-50 symbols)
• Total FMP calls: ~180-300

FMP-Only Screening:

• FMP Stock Screener: 1 call (returns 100-1000 stocks)
• FMP Financial Data: ~500-5000 calls (5 endpoints × 100-1000 symbols)
• Total FMP calls: ~500-5000

Savings: 60-94% reduction in FMP API usage

Cost Analysis

FINVIZ Elite:

• Monthly: $39.50
• Annual: $299.50 (~$24.96/month)

FMP API:

• Free tier: 250 calls/day (sufficient for two-stage screening)
• Starter tier: $29.99/month for 750 calls/day
• Professional tier: $79.99/month for 2000 calls/day

Recommendation:

• For free FMP tier users: Use two-stage screening (FINVIZ + FMP free tier)
• For paid FMP tier users: Either approach works; two-stage is faster
• Budget option: FMP-only with free tier (run screening every few days)
• Optimal option: FINVIZ Elite ($330/year) + FMP free tier = Complete solution

Version History

• v1.1 (November 2025): Added FINVIZ Elite integration for two-stage screening
