Abstract principles become concrete when you run them. These calculators let you feel the mathematics that underlies the approach — the cost of drawdowns, the power of asymmetric positions, and the amplifying effect of concentrated bets.
A 40% drawdown doesn't require a 40% recovery. It requires 67%. The arithmetic is asymmetric — losses compound faster than gains unwind them. These two tools show why protecting capital is not defensive thinking. It is the most aggressive long-term strategy available.

Compounding over time
Compounding Simulator — With vs. Without Drawdown
The Edge is designed to be asymmetric: capped cost, uncapped benefit. A correctly structured put doesn't just protect — it generates capital exactly when other assets are cheapest. These tools show how the payoff shape changes with structure, and how it reshapes the distribution of 20-year outcomes.

Distribution of outcomes
Asymmetry Machine — 20-Year Return Distribution (2,000 simulations)
Monte Carlo simulation. Assumes lognormal returns, annual rebalancing, tail events at 3× modeled frequency. Results are illustrative.
A 2% position in a 10-bagger moves the portfolio by 18%. A 15% position in the same idea moves it by 135%. Diversification limits loss — but it also limits the compounding that only exceptional businesses can deliver. The question is not whether to concentrate, but where to draw the line.
Position size vs. portfolio impact
Concentration Impact Calculator — Single Position Returns
Twenty-five years. Four portfolio structures. The same crashes, the same recoveries — but the compounding gap widens with every cycle. Not because one approach takes more risk, but because avoiding deep drawdowns means never needing a large recovery.

What the hedge returns when S&P 500 falls more than 20% in a year
Crisis zoom — % from pre-crisis peak
Peak Mar 2000. S&P fell 49% to trough in Oct 2002.
60/40 computed from S&P 500 total return and Bloomberg US Aggregate Bond Index annual returns 2000–2024. Permanent Portfolio computed from published 25/25/25/25 allocation (stocks / LT Treasuries / gold / cash). All Weather computed from published allocation (30% stocks · 40% LT bonds · 15% IT bonds · 7.5% gold · 7.5% commodities). Component data from publicly available index returns. Aeternia is a parametric model — not historical data — driven entirely by the sliders above; adjust assumptions to stress-test the thesis. Not a representation of actual or future performance.
