Issue #48: The Split Decision

Issue #48. We’ve come a long way.

This week I’m not burying the lead: the Macro Regime Engine is getting a complete overhaul. Version 2 drops at the end of this month. The 8th Rule has evolved into something I’m calling The Arsenal. And right now, in real time, my old system and my new system are giving me opposite signals on equities.

But here’s the thing: I’ve spent months rebuilding this entire engine from scratch in Python. Independent of TradingView. And the new version.. MRE V2 as of last night is sitting at 29 bearish votes to 3 bullish.

The key insight from the comparison: V2 wins on returns and risk-adjusted metrics. V1 wins on crisis avoidance. They agree 78% of the time. The 22% divergence is almost entirely V2 holding long when V1 has gone flat.

Right now I’m following V1 for the transition period. By end of month, everything migrates to V2. The rest of April is a side-by-side test.

Bitcoin Trend: 25% Long (But the New System Disagrees)

This is where it gets interesting. The 8th Rule.. the original indicator, fired a long signal earlier this week. Substack subs got the alert immediately. I’m currently in a 25% long Bitcoin position plus a 25% long Ethereum position (discretionary).

But the Arsenal.. the new version of The 8th Rule, disagrees. As of last night, the Arsenal BTC signal is sitting in 100% cash.

Here’s why I built the Arsenal and why the disagreement matters:

The Arsenal uses the same mathematical approach across every asset: three envelopes, purely math-based, OHLC data only, dynamic position sizing. No external correlations. No dependencies. Run it on anything.

Arsenal BTC vs 8th Rule vs Buy-and-Hold:

• Annual return: Arsenal beats both

• Sharpe: Huge increase over 8th Rule

• Sortino: 2.71 vs ~1.4 — almost double

• Max drawdown: 30% vs 47% (8th Rule) vs 94% (buy-and-hold)

• Calmar: ~3.0 — almost double the 8th Rule

• $10K grows to: $8.7M (Arsenal) vs $5M (8th Rule) vs $3M (buy-and-hold)

The critical insight: the Arsenal is only fully invested (100%) 22.3% of the time. It spends 62% of the time at 50% position size, averaging 63% when invested. It delivers higher returns with dramatically lower drawdowns.. through position modulation, not leverage.

The 8th Rule sits at 100% invested 91% of the time. It captures more upside but takes more pain.

Gold Arsenal: matches buy-and-hold returns but cuts max drawdown from 44% to 13.8%. Calmar of 0.88. Current signal: 50% gold.

SPY Arsenal: Sortino of 1.01, max drawdown of 10.4%. Current signal: 50% position.

All of these: SPY, BTC, Gold, ETH.. will be available in the member dashboard at end of month.

The Data: CPI Drops, GDP Drops, Fed Does Nothing

Quick macro data because this was a systems-heavy letter:

CPI came in under expectations.. inflation dropping, which is good. GDP also dropping, bad for growth, but arguably good because it gives the Fed more room to cut if they need to. The dual decline of inflation and growth is the kind of environment where the Fed has options.

ISM Services missed. Not much else to write home about.

FedWatch: Basically a lock through the end of 2026.. 73% chance rates don’t move at all. Interestingly, December shows a ~20% shot at one cut. So not completely dead, but don’t hold your breath.

TGA dropped slightly.. tax season noise. Nothing structural.

Final Thoughts

The Macro Regime Engine V1 has been excellent. It caught COVID. It dodged the 2022 bear. It went risk-off weeks before this latest selloff. But it’s tied to TradingView, brittle, and impossible to forward test rigorously.

V2 is independent, exportable, testable, and delivers better risk-adjusted returns over 20+ years of data. The Arsenal beats the 8th Rule on every metric that matters.. while being invested less. Position modulation, not leverage. Surgical deployment of capital.

The whole point of these systems is to chop off the left tail.. the brutal, portfolio-destroying crisis drawdowns that leave you homeless. You’ll still have small losses. -2%, maybe -4%. But you keep the entire right side of the distribution. That’s the thesis. That’s the edge.

Right now: V1 says go long. V2 says 29-to-3 bearish. I’m holding small crypto positions (25% BTC, 25% ETH) and sitting in ~90% cash while both systems run side by side through end of month. Then I pivot fully to V2.

48 weekly issues in the books. The systems keep getting better. The edge keeps compounding. And we’re just getting started.
