Data Collection Phase
Gather all risk-related data before writing the report. Execute these searches:
Step 1: Volatility Data

Extract: next earnings date, recent earnings surprise history, ex-dividend date, pending regulatory decisions, active litigation, upcoming binary events.
Risk Score Methodology
Calculate a composite Risk Score from 0-100 where higher = SAFER (less risky).
Component Scores (each 0-100, higher = safer)
| Component | Weight | What It Measures | Scoring Logic |
|---|---|---|---|
| Volatility Score | 20% | Price stability and predictability | Low beta + low ATR + low HV = high score. Beta <0.8 = 80+. Beta 0.8-1.2 = 50-79. Beta >1.5 = 20-. |
| Drawdown Score | 15% | Historical worst-case behavior | Max drawdown <20% = 80+. 20-40% = 50-79. 40-60% = 25-49. >60% = 0-24. |
| Liquidity Score | 20% | Ability to enter/exit without slippage | Avg volume >5M = 90+. 1-5M = 60-89. 100K-1M = 30-59. <100K = 0-29. |
| Financial Health Score | 20% | Balance sheet strength and stability | D/E <0.5 + strong cash + stable earnings = 80+. High debt + cash burn = 20-. |
| Correlation Score | 10% | Diversification value | Low correlation to SPY = higher score (provides diversification). |
| Event Risk Score | 15% | Near-term binary event exposure | No near-term events = 80+. Earnings within 14 days = 50. FDA/binary event pending = 20-30. |
Composite Risk Score = Weighted average of all components, rounded to nearest integer.
Risk Score Interpretation
| Score | Rating | Description |
|---|---|---|
| 80-100 | Very Safe | Blue-chip stability, high liquidity, minimal event risk |
| 60-79 | Safe | Manageable risk, suitable for most portfolios |
| 40-59 | Moderate | Notable risk factors, size position accordingly |
| 20-39 | Risky | Significant risk, small position size recommended |
| 0-19 | Very Risky | Extreme risk, speculative only, strict risk management required |

Position Sizing Calculator ### Method 1: Fixed Percentage Risk (Standard) Risk a fixed percentage of account equity per trade. **Formula:** Position Size = (Account x Risk%) / (Entry - Stop Loss) | Account Size | 1% Risk | 2% Risk | 3% Risk | |-------------|---------|---------|---------| | $10,000 | <X shares ($X)> | <X shares ($X)> | <X shares ($X)> | | $25,000 | <X shares ($X)> | <X shares ($X)> | <X shares ($X)> | | $50,000 | <X shares ($X)> | <X shares ($X)> | <X shares ($X)> | | $100,000 | <X shares ($X)> | <X shares ($X)> | <X shares ($X)> | | $250,000 | <X shares ($X)> | <X shares ($X)> | <X shares ($X)> | *Based on entry at $<current price> and stop loss at $<2x ATR stop>.* ### Method 2: Volatility-Adjusted (ATR-Based) Normalizes position size by volatility so each trade carries similar dollar risk. **Formula:** Shares = (Account x Risk%) / (ATR x Multiplier) | Account Size | 1x ATR | 2x ATR | 3x ATR | |-------------|--------|--------|--------| | $50,000 | <X shares ($X)> | <X shares ($X)> | <X shares ($X)> | | $100,000 | <X shares ($X)> | <X shares ($X)> | <X shares ($X)> | *Using 14-day ATR of $<X> and 2% account risk.* ### Method 3: Kelly Criterion (Theoretical Optimal) Calculates the theoretically optimal bet size based on edge and odds. **Formula:** Kelly % = W - [(1-W) / R] - W (win rate) = <X%> (based on historical setup success rate or analyst consensus accuracy) - R (reward/risk ratio) = <X>:1 (based on target/stop ratio) - **Full Kelly:** <X%> of account - **Half Kelly (recommended):** <X%> of account - **Quarter Kelly (conservative):** <X%> of account > **Note:** Full Kelly is extremely aggressive. Most practitioners use Half Kelly or less. Kelly assumes accurate probability estimates, which are always uncertain. ### Recommended Position Size | Risk Profile | Shares | Dollar Value | % of $50K Account | Method | |-------------|--------|-------------|-------------------|--------| | Conservative | <X> | $<X> | <X%> | Fixed 1% risk | | Moderate | <X> | $<X> | <X%> | Fixed 2% risk | | Aggressive | <X> | $<X> | <X%> | Half Kelly | --- ## 6. Risk/Reward at Current Levels ### Nearest Support & Resistance | Level | Price | Distance | Type | |-------|-------|----------|------| | Resistance 2 | $<price> | +<X%> | <e.g., "52-week high"> | | Resistance 1 | $<price> | +<X%> | <e.g., "Prior swing high"> | | **Current Price** | **$<price>** | **—** | | | Support 1 | $<price> | -<X%> | <e.g., "50-day MA"> | | Support 2 | $<price> | -<X%> | <e.g., "200-day MA"> | | Support 3 | $<price> | -<X%> | <e.g., "Major horizontal support"> | ### Risk/Reward Scenarios | Entry | Stop (Support) | Target (Resistance) | R:R Ratio | Verdict | |-------|---------------|---------------------|-----------|---------| | $<current> | $<support 1> | $<resistance 1> | <X>:1 | <Favorable/Unfavorable> | | $<current> | $<support 2> | $<resistance 2> | <X>:1 | <Favorable/Unfavorable> | | $<support 1> | $<support 2> | $<resistance 1> | <X>:1 | <Favorable/Unfavorable> | **Best Entry for Risk/Reward:** <specific price and reasoning> --- ## 7. Value at Risk (VaR) Estimate ### Daily VaR (95% confidence) - **Parametric VaR:** $<X> (<X%> of position) - **Interpretation:** On 95% of trading days, the maximum expected loss is $<X> per $10,000 invested. ### Weekly VaR (95% confidence) - **Parametric VaR:** $<X> (<X%> of position) - **Calculation:** Daily VaR x sqrt(5) ### Monthly VaR (95% confidence) - **Parametric VaR:** $<X> (<X%> of position) - **Calculation:** Daily VaR x sqrt(21) ### Conditional VaR (Expected Shortfall) - **CVaR (95%):** $<X> (<X%> of position) - **Interpretation:** When losses exceed the VaR threshold (worst 5% of days), the average loss is $<X> per $10,000 invested. > **VaR Limitation:** VaR measures normal-condition risk. It does NOT capture tail risk (black swans). Actual losses can and do exceed VaR estimates. Use as one input among many, not as a guarantee. --- ## 8.

Calculation Guidance
When performing calculations, use Bash to run Python for precision:
python# Example: Position sizing calculation entry_price = 150.00 stop_loss = 142.00 risk_per_share = entry_price - stop_loss # $8.00 account_sizes = [10000, 25000, 50000, 100000, 250000] risk_percentages = [0.01, 0.02, 0.03] for account in account_sizes: for risk_pct in risk_percentages: dollar_risk = account * risk_pct shares = int(dollar_risk / risk_per_share) position_value = shares * entry_price print(f"${account:,} at {risk_pct:.0%}: {shares} shares (${position_value:,.0f})")
python# Example: VaR calculation import math daily_volatility = 0.025 # 2.5% daily std dev position_value = 10000 daily_var_95 = position_value * daily_volatility * 1.645 weekly_var_95 = daily_var_95 * math.sqrt(5) monthly_var_95 = daily_var_95 * math.sqrt(21) print(f"Daily VaR (95%): ${daily_var_95:.2f}") print(f"Weekly VaR (95%): ${weekly_var_95:.2f}") print(f"Monthly VaR (95%): ${monthly_var_95:.2f}")
Use Python calculations whenever exact numbers are needed. Do not estimate position sizes manually.
Quality Standards
- Every number must be calculated, not estimated. Use Python via Bash for all position sizing, VaR, and Kelly Criterion calculations.
- Risk Score must be defensible. Each component score must have clear reasoning traceable to specific metrics.
- Drawdown scenarios must be grounded in history. Use actual historical drawdowns as anchors, then adjust for current conditions.
- Position sizing must be internally consistent. The stop loss used in sizing tables must match the recommended stop loss.
- Correlation data must be current. Correlations shift over time. Note the lookback period used.
Edge Cases
- If the stock has no options: Skip implied volatility and IV Rank sections. Note that hedging via options is not available.
- If the stock is newly IPO'd (<1 year): Flag limited historical data. Use sector/peer drawdowns as proxies. Widen all risk estimates.
- If the stock is an ETF: Correlation analysis should focus on underlying sector exposure. Drawdown analysis uses the ETF's actual history plus the underlying index history.
- If volume is extremely low (<50K/day): Flag this prominently. Recommend limit orders only. Increase slippage estimates significantly.
