CANSLIM Stock Screener - Phase 3 (Full CANSLIM)

Overview

This skill screens US stocks using William O'Neil's proven CANSLIM methodology, a systematic approach for identifying growth stocks with strong fundamentals and price momentum. CANSLIM analyzes 7 key components: Current Earnings, Annual Growth, Newness/New Highs, Supply/Demand, Leadership/RS Rank, Institutional Sponsorship, and Market Direction.

Phase 3 implements all 7 of 7 components (C, A, N, S, L, I, M), representing 100% of the full methodology.

Two-Stage Approach:

Stage 1 (FMP API + Finviz): Analyze stock universe with all 7 CANSLIM components
Stage 2 (Reporting): Rank by composite score and generate actionable reports

Key Features:

Composite scoring (0-100 scale) with weighted components
Finviz fallback for institutional ownership data (automatic when FMP data incomplete)
Progressive filtering to optimize API usage
JSON + Markdown output formats
Interpretation bands: Exceptional+ (90+), Exceptional (80-89), Strong (70-79), Above Average (60-69)
Bear market protection (M component gating)

Phase 3.1 Component Weights (Original O'Neil weights):

C (Current Earnings): 15%
A (Annual Growth): 20%
N (Newness): 15%
S (Supply/Demand): 15%
L (Leadership/RS Rank): 20% — multi-period weighted RS (3m/6m/12m vs configurable benchmark)
I (Institutional): 10%
M (Market Direction): 5%

Weighted RS Formula:

Weighted RS = 0.40 × rel_3m + 0.30 × rel_6m + 0.30 × rel_12m

Available periods are re-normalized when some are missing. Default benchmark is ^GSPC; override with --rs-benchmark SPY/QQQ/IWM/....

Fallback hierarchy when multi-period data is incomplete:

No benchmark → weighted absolute stock performance + 20% penalty.
All multi-period windows missing but >=50 bars of price history → fall back to the legacy 365-day full-window absolute return as the scoring input (20% penalty if no benchmark).
<50 bars of price history → score=0 with error set.

Future Phases:

Phase 4: FINVIZ Elite integration → 10x faster execution

When to Use This Skill

Explicit Triggers:

"Find CANSLIM stocks"
"Screen for growth stocks using O'Neil's method"
"Which stocks have strong earnings and momentum?"
"Identify stocks near 52-week highs with accelerating earnings"
"Run a CANSLIM screener on [sector/universe]"

Implicit Triggers:

User wants to identify multi-bagger candidates
User is looking for growth stocks with proven fundamentals
User wants systematic stock selection based on historical winners
User needs a ranked list of stocks meeting O'Neil's criteria

When NOT to Use:

Value investing focus (use value-dividend-screener instead)
Income/dividend focus (use dividend-growth-pullback-screener instead)
Bear market conditions (M component will flag - consider raising cash)

Prerequisites

API Requirements:

FMP API key (free tier: 250 calls/day, sufficient for 35 stocks; Starter tier $29.99/mo for 40+ stocks)

requests (FMP API calls)
beautifulsoup4 (Finviz web scraping)
lxml (HTML parsing)

Installation:

pip install requests beautifulsoup4 lxml

Output

Output Directory: reports/ (default) or custom via --output-dir

Generated Files:

canslim_screener_YYYY-MM-DD_HHMMSS.json - Structured data for programmatic use
canslim_screener_YYYY-MM-DD_HHMMSS.md - Human-readable report

Report Contents:

Market Condition Summary (trend, M score, warnings)

Exceptional (80-89): Outstanding fundamentals + momentum, strong buy
Strong (70-79): Solid across components, standard buy
Above Average (60-69): Meets thresholds with minor weaknesses, buy on pullback

Workflow

Step 1: Verify API Access and Requirements

Check if user has FMP API key configured:

# Check environment variable
echo $FMP_API_KEY

# If not set, prompt user to provide it

Requirements:

FMP API key (free tier: 250 calls/day, sufficient for 40 stocks)
Python 3.9+ with required libraries:
- requests (FMP API calls)
- beautifulsoup4 (Finviz web scraping)
- lxml (HTML parsing)

Installation:

pip install requests beautifulsoup4 lxml

If API key is missing, guide user to:

Sign up at https://site.financialmodelingprep.com/developer/docs
Get free API key (250 calls/day)
Set environment variable: export FMP_API_KEY=your_key_here

Step 2: Determine Stock Universe

Option A: Default Universe (Recommended) Use top 40 S&P 500 stocks by market cap (predefined in script):

python3 skills/canslim-screener/scripts/screen_canslim.py

Option B: Custom Universe User provides specific symbols or sector:

python3 skills/canslim-screener/scripts/screen_canslim.py \
  --universe AAPL MSFT GOOGL AMZN NVDA META TSLA

Option C: Sector-Specific User can provide sector-focused list (Technology, Healthcare, etc.)

API Budget Considerations (Phase 3):

40 stocks × 7 FMP calls/stock = 280 API calls
- FMP: 7 calls/stock (profile, quote, income×2, historical_90d, historical_365d, institutional)
- Finviz: ~1.8 calls/stock (institutional ownership fallback, 2s rate limit, not counted in FMP budget)
Market data (^GSPC quote, ^VIX quote, ^GSPC 52-week history): 3 FMP calls
Total: ~283 FMP calls per screening run (exceeds 250 free tier)
Recommendation: Use --max-candidates 35 for free tier (35 × 7 + 3 = 248 calls), or upgrade to FMP Starter tier ($29.99/mo, 750 calls/day) for full 40-stock screening

Step 3: Execute CANSLIM Screening Script

Run the main screening script with appropriate parameters:

cd skills/canslim-screener/scripts

# Basic run (40 stocks, top 20 in report)
python3 screen_canslim.py --api-key $FMP_API_KEY

# Custom parameters
python3 screen_canslim.py \
  --api-key $FMP_API_KEY \
  --max-candidates 40 \
  --top 20 \
  --output-dir ../../../

# Custom RS benchmark (Phase 3.1)
python3 screen_canslim.py --rs-benchmark SPY

# Disable L component (saves per-stock 365-day fetch; L fixed at neutral 50)
python3 screen_canslim.py --disable-rs

Script Workflow (Phase 3 - Full CANSLIM):

Market Direction (M): Analyze S&P 500 trend vs 50-day EMA (using real historical data for accurate EMA)
- If bear market detected (M=0), warn user to raise cash
S&P 500 Historical Data: Fetch 52-week data for M component EMA and L component RS calculation
Stock Analysis: For each stock, calculate:
- C Component: Quarterly EPS/revenue growth (YoY)
- A Component: 3-year EPS CAGR and stability
- N Component: Distance from 52-week high, breakout detection
- S Component: Volume-based accumulation/distribution (up-day vs down-day volume)
- L Component: 52-week Relative Strength vs S&P 500
- I Component: Institutional holder count + ownership % (with Finviz fallback)
Composite Scoring: Weighted average with all 7 component breakdown
Ranking: Sort by composite score (highest first)
Reporting: Generate JSON + Markdown outputs

Expected Execution Time (Phase 3):

40 stocks: ~2 minutes (additional 52-week history fetch per stock for L component)
Finviz fallback adds ~2 seconds per stock (rate limiting)
L component requires 365-day historical data for each stock

Finviz Fallback Behavior:

Triggers automatically when FMP sharesOutstanding unavailable
Scrapes institutional ownership % from Finviz.com (free, no API key)
Increases I component accuracy from 35/100 (partial data) to 60-100/100 (full data)
User sees: ✅ Using Finviz institutional ownership for NVDA: 68.3%

Step 4: Read and Parse Screening Results

The script generates two output files:

canslim_screener_YYYY-MM-DD_HHMMSS.json - Structured data
canslim_screener_YYYY-MM-DD_HHMMSS.md - Human-readable report

Read the Markdown report to identify top candidates:

# Find the latest report
ls -lt canslim_screener_*.md | head -1

# Read the report
cat canslim_screener_YYYY-MM-DD_HHMMSS.md

Report Structure (Phase 3 - Full CANSLIM):

Market Condition Summary (trend, M score, warnings)
Top N CANSLIM Candidates (ranked, N = --top parameter)
For each stock:
- Composite Score and Rating (Exceptional+/Exceptional/Strong/etc.)
- Component Breakdown (C, A, N, S, L, I, M scores with details)
- Interpretation (rating description, guidance, weakest component)
- Warnings (quality issues, market conditions, data source notes)
Summary Statistics (rating distribution)
Methodology note (Phase 3: 7 components, 100% coverage)

Component Details in Report:

S Component: "Up/Down Volume Ratio: 1.06 ✓ Accumulation"
L Component (Phase 3.1): "3m/6m/12m: +12.4%/+18.7%/+44.1% (rel +5.2%/+8.3%/+22.0%) | RS: 88 (Strong)"
I Component: "6199 holders, 68.3% ownership ⭐ Superinvestor"

A new Summary Table appears above the candidate list in Phase 3.1 reports, showing rank, symbol, composite score, rating, RS rating, and RS percentile for quick scanning.

Step 5: Analyze Top Candidates and Provide Recommendations

Review the top-ranked stocks and cross-reference with knowledge bases:

Reference Documents to Consult:

references/interpretation_guide.md - Understand rating bands and portfolio sizing
references/canslim_methodology.md - Deep dive into component meanings (now includes S and I)
references/scoring_system.md - Understand scoring formulas (Phase 3 weights)

Analysis Framework:

For Exceptional+ stocks (90-100 points):

All components near-perfect (C≥85, A≥85, N≥85, S≥80, L≥85, I≥80, M≥80)
Guidance: Immediate buy, aggressive position sizing (15-20% of portfolio)
Example: "NVDA scores 97.2 - explosive quarterly earnings (100), strong 3-year growth (95), at new highs (98), volume accumulation (85), RS leader (92), strong institutional support (90), uptrend market (100)"

For Exceptional stocks (80-89 points):

Outstanding fundamentals + strong momentum
Guidance: Strong buy, standard sizing (10-15% of portfolio)

For Strong stocks (70-79 points):

Solid across all components, minor weaknesses
Guidance: Buy, standard sizing (8-12% of portfolio)
Phase 3 Example: "Stock scores 77.5 - strong earnings (85), solid growth (80), near high (70), accumulation (60), RS leader (75), good institutions (60), uptrend (90)"

For Above Average stocks (60-69 points):

Meets thresholds, one component weak
Guidance: Buy on pullback, conservative sizing (5-8% of portfolio)

Bear Market Override:

If M component = 0 (bear market detected), do NOT buy regardless of other scores
Guidance: Raise 80-100% cash, wait for market recovery
CANSLIM does not work in bear markets (3 out of 4 stocks follow market trend)

Step 6: Generate User-Facing Report

Create a concise, actionable summary for the user:

# CANSLIM Stock Screener - Phase 3 (Full CANSLIM)

## Overview

This skill screens US stocks using William O'Neil's proven CANSLIM methodology, a systematic approach for identifying growth stocks with strong fundamentals and price momentum. CANSLIM analyzes 7 key components: **C**urrent Earnings, **A**nnual Growth, **N**ewness/New Highs, **S**upply/Demand, **L**eadership/RS Rank, **I**nstitutional Sponsorship, and **M**arket Direction.

**Phase 3** implements all 7 of 7 components (C, A, N, S, L, I, M), representing **100% of the full methodology**.

**Two-Stage Approach:**
1. **Stage 1 (FMP API + Finviz)**: Analyze stock universe with all 7 CANSLIM components
2. **Stage 2 (Reporting)**: Rank by composite score and generate actionable reports

**Key Features:**
- Composite scoring (0-100 scale) with weighted components
- **Finviz fallback** for institutional ownership data (automatic when FMP data incomplete)
- Progressive filtering to optimize API usage
- JSON + Markdown output formats
- Interpretation bands: Exceptional+ (90+), Exceptional (80-89), Strong (70-79), Above Average (60-69)
- Bear market protection (M component gating)

**Phase 3.1 Component Weights (Original O'Neil weights):**
- C (Current Earnings): 15%
- A (Annual Growth): 20%
- N (Newness): 15%
- S (Supply/Demand): 15%
- L (Leadership/RS Rank): 20% — multi-period weighted RS (3m/6m/12m vs configurable benchmark)
- I (Institutional): 10%
- M (Market Direction): 5%

**Weighted RS Formula:**
```
Weighted RS = 0.40 × rel_3m + 0.30 × rel_6m + 0.30 × rel_12m
```
Available periods are re-normalized when some are missing. Default benchmark is `^GSPC`;
override with `--rs-benchmark SPY/QQQ/IWM/...`.

**Fallback hierarchy when multi-period data is incomplete:**
1. No benchmark → weighted absolute stock performance + 20% penalty.
2. All multi-period windows missing but >=50 bars of price history → fall back to the
   legacy 365-day full-window absolute return as the scoring input (20% penalty if no
   benchmark).
3. <50 bars of price history → score=0 with `error` set.

**Future Phases:**
- Phase 4: FINVIZ Elite integration → 10x faster execution

2. Get free API key (250 calls/day)
3. Set environment variable: `export FMP_API_KEY=your_key_here`

### Step 2: Determine Stock Universe

**Option A: Default Universe (Recommended)**
Use top 40 S&P 500 stocks by market cap (predefined in script):

```bash
python3 skills/canslim-screener/scripts/screen_canslim.py
```

**Option B: Custom Universe**
User provides specific symbols or sector:

```bash
python3 skills/canslim-screener/scripts/screen_canslim.py \
  --universe AAPL MSFT GOOGL AMZN NVDA META TSLA
```

**Option C: Sector-Specific**
User can provide sector-focused list (Technology, Healthcare, etc.)

**API Budget Considerations (Phase 3):**
- 40 stocks × 7 FMP calls/stock = 280 API calls
  - FMP: 7 calls/stock (profile, quote, income×2, historical_90d, historical_365d, institutional)
  - Finviz: ~1.8 calls/stock (institutional ownership fallback, 2s rate limit, not counted in FMP budget)
- Market data (^GSPC quote, ^VIX quote, ^GSPC 52-week history): 3 FMP calls
- Total: ~283 FMP calls per screening run (exceeds 250 free tier)
- **Recommendation**: Use `--max-candidates 35` for free tier (35 × 7 + 3 = 248 calls), or upgrade to FMP Starter tier ($29.99/mo, 750 calls/day) for full 40-stock screening

### Step 3: Execute CANSLIM Screening Script

Run the main screening script with appropriate parameters:

```bash
cd skills/canslim-screener/scripts

python3 screen_canslim.py --rs-benchmark SPY

# Disable L component (saves per-stock 365-day fetch; L fixed at neutral 50)
python3 screen_canslim.py --disable-rs
```

**Script Workflow (Phase 3 - Full CANSLIM):**
1. **Market Direction (M)**: Analyze S&P 500 trend vs 50-day EMA (using real historical data for accurate EMA)
   - If bear market detected (M=0), warn user to raise cash
2. **S&P 500 Historical Data**: Fetch 52-week data for M component EMA and L component RS calculation
3. **Stock Analysis**: For each stock, calculate:

4. **Composite Scoring**: Weighted average with all 7 component breakdown
5. **Ranking**: Sort by composite score (highest first)
6. **Reporting**: Generate JSON + Markdown outputs

**Expected Execution Time (Phase 3):**
- 40 stocks: **~2 minutes** (additional 52-week history fetch per stock for L component)
- Finviz fallback adds ~2 seconds per stock (rate limiting)
- L component requires 365-day historical data for each stock

**Finviz Fallback Behavior:**
- Triggers automatically when FMP `sharesOutstanding` unavailable
- Scrapes institutional ownership % from Finviz.com (free, no API key)
- Increases I component accuracy from 35/100 (partial data) to 60-100/100 (full data)
- User sees: `✅ Using Finviz institutional ownership for NVDA: 68.3%`

### Step 4: Read and Parse Screening Results

The script generates two output files:
- `canslim_screener_YYYY-MM-DD_HHMMSS.json` - Structured data
- `canslim_screener_YYYY-MM-DD_HHMMSS.md` - Human-readable report

Read the Markdown report to identify top candidates:

```bash
# Find the latest report
ls -lt canslim_screener_*.md | head -1

# Read the report
cat canslim_screener_YYYY-MM-DD_HHMMSS.md
```

**Report Structure (Phase 3 - Full CANSLIM):**

For **Above Average stocks (60-69 points)**:
- Meets thresholds, one component weak
- Guidance: Buy on pullback, conservative sizing (5-8% of portfolio)

**Bear Market Override:**
- If M component = 0 (bear market detected), **do NOT buy** regardless of other scores
- Guidance: Raise 80-100% cash, wait for market recovery
- CANSLIM does not work in bear markets (3 out of 4 stocks follow market trend)
