Portfolio Construction

Putting It All Together — Core vs satellite, regime allocation, and practical templates

February 2026 · 20 min read

You understand liquidity cycles. You know how to manage risk. Now it's time to put it together into an actual portfolio—a system that compounds wealth across market cycles.

Most people either over-diversify (owning a little of everything, capturing nothing) or under-diversify (all-in on one asset, praying it works). Neither approach survives the Fourth Turning.

This article gives you frameworks that actually work.

The Goal

A portfolio that grows in bull markets, survives bear markets, and compounds through the cycle. Not maximum returns—maximum risk-adjusted returns over time.

The Core-Satellite Approach

The core-satellite model divides your portfolio into two buckets:

The core gives you stability and compound growth. The satellites give you alpha—the ability to outperform when you're right about macro conditions.

Why This Works

  • Protects against overconfidence — Even if your macro calls are wrong, the core keeps compounding
  • Allows tactical flexibility — Satellites let you lean into liquidity expansions
  • Psychologically sustainable — You're not betting everything on each view

Asset Allocation Across Regimes

Remember the GRID model from Step 1? Different regimes favor different assets. Your portfolio should adapt.

Regime Favored Assets Avoid/Reduce
Goldilocks
(↑Growth, ↓Inflation)
Stocks, Growth stocks, BTC Commodities, Gold
Reflation
(↑Growth, ↑Inflation)
Commodities, Value stocks, BTC Bonds, Growth stocks
Inflation
(↓Growth, ↑Inflation)
Gold, Commodities, Cash Bonds, Stocks
Deflation
(↓Growth, ↓Inflation)
Long bonds, Cash, Quality stocks Commodities, Cyclicals

Your core stays relatively stable. Your satellites shift based on regime.

The Barbell Strategy (Taleb)

Nassim Taleb's barbell strategy is perfectly suited for the Fourth Turning—an era of extreme outcomes and fat tails.

The idea: avoid the middle. Hold extremely safe assets on one end, and extremely asymmetric bets on the other. Nothing in between.

🏋️ The Barbell Portfolio

80%
20%
Ultra-safe (T-bills, cash): 80-90% Asymmetric bets (BTC, options): 10-20%

Maximum downside is capped (you can only lose the speculative portion). Maximum upside is uncapped. This is antifragile.

The barbell works because you can never lose more than 10-20%, but your winners can 10x, 50x, or 100x. The math heavily favors this structure in volatile regimes.

Ray Dalio's All-Weather Principles

Dalio's All-Weather portfolio is designed to perform reasonably in any economic environment—growth up/down, inflation up/down.

🌤️ All-Weather Portfolio

30%
40%
15%
15%
Stocks 30% Long-Term Bonds 40% Gold 15% Commodities 15%

Fourth Turning Caveat

The original All-Weather has 40% in long bonds. In a fiscal dominance / debasement regime, this may be problematic. Consider reducing bond exposure and adding Bitcoin as a "digital gold" hedge.

Rebalancing Strategies

Rebalancing means selling winners and buying losers to maintain your target allocation. It forces you to sell high and buy low—the opposite of what emotions tell you to do.

Calendar Rebalancing

Rebalance on a fixed schedule—quarterly or annually. Simple, mechanical, removes emotion.

Threshold Rebalancing

Rebalance when any position drifts more than X% from target (common threshold: 5%). More responsive to big moves.

Opportunistic Rebalancing

Rebalance when you're deploying new cash or during extreme market moves. Tax-efficient and flexible.

🎯 Action Items: Choose Your Rebalancing Method

  1. Decide on frequency: Quarterly is a good default
  2. Set threshold alerts: Flag positions that drift >5% from target
  3. Rebalance with new money first: More tax-efficient than selling
  4. Don't over-rebalance: Transaction costs and taxes add up

Tax-Efficient Positioning

Taxes are a major drag on returns. Smart positioning can save you significantly over time.

Practical Templates by Net Worth

Your portfolio should evolve with your wealth. Here are frameworks for different stages:

💰 Building Phase ($0 - $100K)

70%
15%
15%
Index Funds 70% BTC 15% Cash/Emergency 15%

Priority: Maximize savings rate. Time is your greatest asset. Avoid complexity.

💰 Growth Phase ($100K - $1M)

50%
15%
10%
15%
10%
Stocks 50% BTC 15% Gold 10% Real Estate 15% Cash 10%

Priority: Begin diversifying into real assets. Establish core-satellite structure.

💰 Preservation Phase ($1M+)

35%
10%
15%
20%
10%
10%
Stocks 35% BTC 10% Gold 15% Real Estate 20% Bonds 10% Cash 10%

Priority: Capital preservation becomes paramount. Reduce volatility, maintain purchasing power.

Key Takeaways

  • Core-Satellite structure — 70-85% stable core, 15-30% tactical satellites
  • Adapt to regimes — Shift satellites based on GRID model conditions
  • Consider the Barbell — Ultra-safe + asymmetric bets, nothing in between
  • Rebalance systematically — Forces buy low, sell high
  • Tax efficiency matters — Asset location and long-term holding save significantly
  • Evolve with wealth — Different stages require different allocations
