Many strategies rely less on code than on mathematics. Strategy Arena draws on the theories of 3 authors who shaped finance.
Nassim Taleb — The Barbell Strategy: Taleb (author of The Black Swan) has a simple rule: put 85% of your capital in ultra-safe assets (bonds, stablecoins), and 15% in very risky bets with high potential. Zero middle ground. Why? Because extreme events (black swans) happen more often than expected. With the Barbell, you're protected AND exposed to positive "fat tails".
Benoit Mandelbrot — Power Laws: Mandelbrot showed that price changes do NOT follow a normal distribution (bell curve). Extreme moves happen far more often than classical models predict. Strategy Arena takes this into account: instead of assuming "-5% in a day" is nearly impossible, our measurements include kurtosis, an indicator of fat tails.
William Sharpe — The Nobel Ratio: The Sharpe Ratio dates from 1966. William Sharpe received the Nobel Memorial Prize in Economics in 1990 for his work on the pricing of financial assets (CAPM). Return divided by risk. Simple but useful: the ratio relates return to the risk taken, instead of comparing raw returns. Today, it is a reference metric in asset management.
Nassim Taleb — The 85/15 Barbell in Detail: The Barbell strategy isn't just an allocation — it's a philosophy. The 85% in safe assets (bonds, stablecoins, cash) limits your maximum loss. The 15% in risky assets (BTC, options, speculative altcoins) exposes you to asymmetric gains. Result: your loss is bounded (about -15%, if the safe part holds) and your gain stays open. This is the idea of antifragility — limiting damage while staying exposed to upside.
Benoit Mandelbrot — Power Laws: The classical model (Gaussian/bell curve distribution) treats a -20% crash in one day as virtually impossible. Yet the Dow Jones lost 22.6% on October 19, 1987, and bitcoin fell more than 35% on March 12, 2020. Mandelbrot showed that markets follow power laws, not bell curves. Distribution tails are "fat" — extreme events are far more frequent than expected. Strategy Arena takes this into account by measuring kurtosis.
Harry Markowitz — The Efficient Frontier (Nobel 1990): Markowitz showed that combining weakly correlated assets reduces portfolio risk; the phrase about the only "free lunch" in finance is attributed to him. For each risk level, there exists ONE optimal portfolio that maximizes return. All these portfolios together form the efficient frontier — a curve above which it's mathematically impossible to be.
William Sharpe — The Return/Risk Ratio (Nobel 1990): Sharpe gave Markowitz a practical tool: a single number that summarizes "is this return worth the risk taken?" Sharpe Ratio = (Return - Risk-free rate) / Volatility. Simple, elegant, and widely used in asset management.
Two other thinkers influence Strategy Arena: Choueifaty (TOBAM founder) argues the thesis that BTC follows gold with a roughly 200-day lag and x15 multiplier — a hypothesis you can observe (and falsify) on /btc-vs-gold. And Ray Dalio (Bridgewater) formalized economic cycles into 4 phases, influencing our regime detector.
