Abstract:

In the final installment of our series, we operationalize Dr. Glen Brown’s Enhanced Equity Valuation Model by automating recalibrations, setting up real-time alerts, and integrating valuations into portfolio construction and risk budgeting. Anchored in Law 8 (Transaction-Cost & Slippage Optimization) and Law 7 (Portfolio-Level Noise Budget), this part shows you how to build a live system that keeps your targets fresh and your portfolio optimally balanced.

1. Automation & Alerts

Law 8 – Transaction-Cost & Slippage Optimization: Minimize model latency and execution frictions by automating every recalibration and flag.

1. Real-Time Data Pipeline
   • Price feeds: connect to market API (e.g., Bloomberg, Alpha Vantage).
   • Fundamentals: update EPS, P/E, debt, ROIC from your database monthly.
   • Volatility & Macro: pull ATR, VIX, yield-curve, and regime signals daily.
2. Recalibration Logic IF |P₀ – FV₀|/FV₀ ≥ 5% OR t_since_last ≥ 7 days: → Re-solve EVDF = (P₀/FV₀)^(12/tₒ𝒷ₛ), EVGF = 1/EVDF
3. Alert Triggers
   • p_Bear > 50% ⇒ “High Bear Regime: consider hedges.”
   • P₀ > FV₀ × (1 + MOS) ⇒ “Overvalued: review position sizing.”
   • EVDF crosses above/below key thresholds (e.g., 1.2, 0.8) ⇒ regime shift alert.
4. Notification Channels
   • Email or SMS via SMTP/API for critical alerts.
   • ChatOps: integrate with Slack/Microsoft Teams using webhooks.
   • Dashboard UI: Excel with VBA or Python Dash/Flask app displaying live metrics.

2. Portfolio Integration & Risk Budgeting

Law 7 – Portfolio-Level Noise Budget: Allocate capital and hedges based on each position’s expected mispricing noise.

1. Ranking by Mispricing Mispricingᵢ = (P₀ᵢ – E[FV₁]ᵢ) / E[FV₁]ᵢ • Sort tickers; highest negative mispricing → larger long weight.
2. Noise-Share Risk Allocation σ_noiseᵢ = StdDev(EVDFᵢ history) NoiseShareᵢ = σ_noiseᵢ / Σσ_noise_j Riskᵢ = TotalRiskBudget × NoiseShareᵢ • Positions sizing ∝ riskᵢ, so noisier names get smaller allocations.
3. Hedging the Bear Tail
   • Identify bottom decile by Mispricing.
   • Purchase protective puts or use inverse ETF exposure equal to Riskᵢ.
4. Rebalancing Rules
   • Monthly: refresh rankings and risk budgets.
   • Threshold: rebalance if any position weight deviates >10% from target.

3. Implementation Roadmap

1. Design Data Architecture – Set up ETL to ingest prices, fundamentals, volatility, macro signals.
2. Build Model Engine – Modular scripts/functions for FV₀, EVDF/EVGF, regime splits, scenario forecasts, probability weighting, MOS, overlays.
3. Develop Dashboard & Alerts – Excel with VBA macros or a Python web app (Dash/Flask). – Configure scheduled tasks (cron or Airflow) to run recalibrations & send notifications.
4. Back-Test & Validate – Run historical simulations to measure hit rates on alerts and portfolio returns.
5. Deploy & Monitor – Host on a secure server/VPS. – Set up logging and automated health checks.

4. Conclusion

By automating recalibrations and seamlessly integrating into portfolio construction, Dr. Glen Brown’s model evolves into a fully operational system—continually aligned with market dynamics and grounded in the Nine-Laws risk framework. This end-to-end process transforms static valuation into a live, disciplined trading engine.
