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.

Position Sizing Calculations
Use execute_code (Python) for all calculations:
# Method 1: Fixed Percentage Risk
entry_price = [current_price]
stop_loss = entry_price - (2 * atr_14) # 2x ATR stop
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})")
# Method 2: Kelly Criterion (Half Kelly recommended)
win_rate = 0.55 # estimated
reward_risk_ratio = 2.0 # based on setup
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%}")
# Method 3: VaR (95% confidence)
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}")
