Analyze a single ticker:

uv run {baseDir}/scripts/analyze_stock.py AAPL
uv run {baseDir}/scripts/analyze_stock.py MSFT --output json

Compare multiple tickers:

uv run {baseDir}/scripts/analyze_stock.py AAPL MSFT GOOGL

Cryptocurrency Analysis (v5.0)

Analyze top 20 cryptocurrencies by market cap:

uv run {baseDir}/scripts/analyze_stock.py BTC-USD
uv run {baseDir}/scripts/analyze_stock.py ETH-USD SOL-USD

Supported Cryptos: BTC-USD, ETH-USD, BNB-USD, SOL-USD, XRP-USD, ADA-USD, DOGE-USD, AVAX-USD, DOT-USD, MATIC-USD, LINK-USD, ATOM-USD, UNI-USD, LTC-USD, BCH-USD, XLM-USD, ALGO-USD, VET-USD, FIL-USD, NEAR-USD

Crypto Analysis Dimensions:

• Market cap (large/mid/small classification)

• BTC correlation (30-day)

• Momentum (RSI, price range)

• Market context (VIX, general market regime)

Portfolio Management (v5.0)

Create and manage portfolios with mixed assets (stocks + crypto):

# Create portfolio

# Add assets
uv run {baseDir}/scripts/portfolio.py add AAPL --quantity 100 --cost 150.00
uv run {baseDir}/scripts/portfolio.py add BTC-USD --quantity 0.5 --cost 40000 --portfolio "My Portfolio"

# View holdings with current P&L
uv run {baseDir}/scripts/portfolio.py show

# Update/remove assets
uv run {baseDir}/scripts/portfolio.py update AAPL --quantity 150
uv run {baseDir}/scripts/portfolio.py remove BTC-USD

# List/delete portfolios
uv run {baseDir}/scripts/portfolio.py list
uv run {baseDir}/scripts/portfolio.py delete "My Portfolio"

Portfolio Storage: ~/.clawdbot/skills/stock-analysis/portfolios.json

Portfolio Analysis (v5.0)

Analyze all assets in a portfolio with optional period returns:

# Analyze portfolio
uv run {baseDir}/scripts/analyze_stock.py --portfolio "My Portfolio"

# With period returns (daily/weekly/monthly/quarterly/yearly)
uv run {baseDir}/scripts/analyze_stock.py --portfolio "My Portfolio" --period weekly
uv run {baseDir}/scripts/analyze_stock.py -p "My Portfolio" --period monthly

Portfolio Summary includes:

• Total cost, current value, P&L

• Period return (if specified)

• Concentration warnings (>30% in single asset)

• Recommendation summary (BUY/HOLD/SELL counts)

Examples:

• ✅ CORRECT: uv run {baseDir}/scripts/analyze_stock.py BAC

• ✅ CORRECT: uv run {baseDir}/scripts/analyze_stock.py BTC-USD

• ❌ WRONG: uv run {baseDir}/scripts/analyze_stock.py === BANK OF AMERICA (BAC) - Q4 2025 EARNINGS ===

• ❌ WRONG: uv run {baseDir}/scripts/analyze_stock.py "Bank of America"

Use the ticker symbol only (e.g., BAC, not "Bank of America"). For crypto, use the -USD suffix (e.g., BTC-USD).

Analysis Components

The script evaluates eight key dimensions:

• Earnings Surprise (30% weight): Actual vs expected EPS, revenue beats/misses

• Fundamentals (20% weight): P/E ratio, profit margins, revenue growth, debt levels

• Analyst Sentiment (20% weight): Consensus ratings, price target vs current price

• Historical Patterns (10% weight): Past earnings reactions, volatility

• Market Context (10% weight): VIX, SPY/QQQ trends, market regime

• Sector Performance (15% weight): Stock vs sector comparison, sector trends

• Momentum (15% weight): RSI, 52-week range, volume, relative strength

• Sentiment Analysis (10% weight): Fear/Greed Index, short interest, VIX term structure, insider trading, put/call ratio

Sentiment Sub-Indicators:

• Fear & Greed Index (CNN): Contrarian signal (extreme fear = buy opportunity, extreme greed = caution)

• Short Interest: High shorts + squeeze potential = bullish; justified shorts = bearish

• VIX Term Structure: Contango = complacency/bullish; backwardation = stress/bearish

• Insider Activity: Net buying/selling from SEC Form 4 filings (90-day window)

• Put/Call Ratio: High ratio = excessive fear/bullish; low ratio = complacency/bearish

Weights auto-normalize if some components unavailable.

Special Timing Checks:

• Pre-earnings warning (< 14 days): Recommends HOLD instead of BUY

• Post-earnings spike detection (> 15% in 5 days): Flags "gains priced in"

• Overbought conditions (RSI > 70 + near 52w high): Reduces confidence

Timing Warnings & Risk Flags

The script detects high-risk scenarios:

Earnings Timing

• Pre-Earnings Period: If earnings < 14 days away, BUY signals become HOLD

• Post-Earnings Spike: If stock up > 15% in 5 days after earnings, warns "gains may be priced in"

Technical Risk

• Overbought Conditions: RSI > 70 + near 52-week high = high-risk entry

Market Risk

• High VIX: Market fear (VIX > 30) reduces confidence in BUY signals

• Risk-Off Mode (v4.0.0): When safe-havens (GLD, TLT, UUP) rise together, reduces BUY confidence by 30%

Detects flight to safety across gold, treasuries, and USD

• Triggers when GLD ≥ +2%, TLT ≥ +1%, UUP ≥ +1% (5-day change)

Sector Risk

• Sector Weakness: Stock may look good but sector is rotating out

Geopolitical Risk (v4.0.0)

The script now scans breaking news (last 24h) for crisis keywords and automatically flags affected stocks:

• Taiwan Conflict: Semiconductors (NVDA, AMD, TSM, INTC, etc.) → 30% confidence penalty

• China Tensions: Tech/Consumer (AAPL, QCOM, NKE, SBUX, etc.) → 30% confidence penalty

• Russia-Ukraine: Energy/Materials (XOM, CVX, MOS, CF, etc.) → 30% confidence penalty

• Middle East: Oil/Defense (XOM, LMT, RTX, etc.) → 30% confidence penalty

• Banking Crisis: Financials (JPM, BAC, WFC, C, etc.) → 30% confidence penalty

If a ticker is not in the affected list but its sector is exposed, applies a 15% confidence penalty.

Example Alert:

⚠️ SECTOR RISK: Tech supply chain and consumer market exposure (detected: china, tariff)

Breaking News Alerts (v4.0.0)

• Scans Google News RSS for crisis keywords (war, recession, sanctions, disasters, etc.)

• Displays up to 2 breaking news alerts in caveats (last 24 hours)

• Uses 1-hour cache to avoid excessive API calls

Output Format

Default (text): Concise buy/hold/sell signal with 3-5 bullet points and caveats

JSON: Structured data with scores, metrics, and raw data for further analysis

Limitations

• Data freshness: Yahoo Finance may lag 15-20 minutes

• Sentiment data staleness:

Short interest data lags ~2 weeks (FINRA reporting schedule)

• Insider trades may lag filing by 2-3 days

• VIX term structure only updates during futures trading hours

• Breaking news limitations (v4.0.0):

Google News RSS may lag by 15-60 minutes

• Keyword matching may have false positives/negatives

• Does not analyze sentiment, only detects keywords

• 1-hour cache means alerts may be slightly stale

• Missing data: Not all stocks have analyst coverage, options chains, or complete fundamentals

• Execution time: 3-5s per stock with async parallel fetching and caching (shared indicators cached for 1h)

• Disclaimer: All outputs include prominent "not financial advice" warning

• US markets only: Non-US tickers may have incomplete data

Error Handling

The script gracefully handles:

• Invalid tickers → Clear error message

• Missing analyst data → Signal based on available metrics only

• API failures → Retry with exponential backoff, fail after 3 attempts
