Data Collection
Run these searches:
- Volatility:
"<TICKER> stock beta volatility average true range ATR" + "<TICKER> historical volatility 30 day implied volatility" → beta, 14-day ATR, 30/60-day HV, implied vol
- Drawdowns:
"<TICKER> stock maximum drawdown worst decline history" + "<TICKER> stock crash 2020 2022 bear market performance" → max drawdown, COVID crash, 2022 bear market, recovery time
- Correlation:
"<TICKER> stock correlation S&P 500 sector ETF" → correlation with SPY, sector ETF, TLT, VIX
- Liquidity:
"<TICKER> average daily volume market cap shares outstanding float" → avg volume, avg dollar volume, float, short interest, bid-ask spread
- Current Price & Technical Context:
"<TICKER> stock price today 52 week high low moving averages" → current price, 52-week range, key MAs, RSI, key support/resistance
- Fundamental Risk:
"<TICKER> debt ratio cash position earnings stability" → D/E, interest coverage, cash, earnings variability
- Event Risk:
"<TICKER> next earnings date ex dividend date regulatory" → next earnings, pending regulatory decisions, litigation
Risk Score Methodology (0-100, higher = safer)
| Component | Weight | Scoring Logic |
|---|
| Volatility | 20% | Beta < 0.8 = 80+; 0.8-1.2 = 50-79; > 1.5 = 20- |
| Drawdown Resilience | 15% | Max drawdown < 20% = 80+; 20-40% = 50-79; 40-60% = 25-49; > 60% = 0-24 |
| Liquidity | 20% | Avg volume > 5M = 90+; 1-5M = 60-89; 100K-1M = 30-59; < 100K = 0-29 |
| Financial Health | 20% | D/E < 0.5 + strong cash + stable earnings = 80+; high debt + burn = 20- |
| Correlation | 10% | Low correlation to SPY = higher score (diversification value) |
| Event Risk | 15% | No near-term events = 80+; earnings within 14 days = 50; binary event pending = 20-30 |
Composite Risk Score = Weighted average, rounded to nearest integer.
| Score | Rating | Description |
|---|
| 80-100 | Very Safe | Blue-chip stability, high liquidity |
| 60-79 | Safe | Manageable risk, suitable for most portfolios |
| 40-59 | Moderate | Notable risk factors, size accordingly |
| 20-39 | Risky | Significant risk, small position recommended |
| 0-19 | Very Risky | Extreme risk, speculative only |
Position Sizing Calculations
Use execute_code (Python) for all calculations:
entry_price = [current_price]
stop_loss = entry_price - (2 * atr_14)
risk_per_share = entry_price - stop_loss
account_sizes = [10000, 25000, 50000, 100000, 250000]
risk_percentages = [0.01, 0.02, 0.03]
for account in account_sizes:
for risk_pct in risk_percentages:
dollar_risk = account * risk_pct
shares = int(dollar_risk / risk_per_share)
position_value = shares * entry_price
print(f"${account:,} at {risk_pct:.0%}: {shares} shares (${position_value:,.0f})")
win_rate = 0.55
reward_risk_ratio = 2.0
kelly_pct = win_rate - ((1 - win_rate) / reward_risk_ratio)
half_kelly = kelly_pct / 2
print(f"Full Kelly: {kelly_pct:.1%} | Half Kelly: {half_kelly:.1%}")
import math
daily_vol = [30_day_hv_decimal]
position_value = 10000
daily_var = position_value * daily_vol * 1.645
weekly_var = daily_var * math.sqrt(5)
monthly_var = daily_var * math.sqrt(21)
print(f"Daily VaR: ${daily_var:.2f} | Weekly: ${weekly_var:.2f} | Monthly: ${monthly_var:.2f}")
