DAI20 — Digital Architecture Index

DAI20 is calculated the way a real cap-weighted equity index is calculated — a basket value divided by a divisor, with the divisor fixed at genesis so the index reads 100 at that moment. A daily resetting leverage factor (LF=5×) amplifies every basket move: a +1% basket change becomes a +5% token price move.

The general formula: Index(t) = 100 × (1 + LF × (R(t) − 1)), where R(t) is the raw basket ratio relative to genesis.

Cap-Weighted (default): R(t) = TotalMarketCap(t) / TotalMarketCap(genesis).

Equal-Weight: R(t) = average( Price_i(t) / Price_i(genesis) ) across all 20.

50/50 Balanced: R(t) = 0.5 × MktCap_NASDAQ(t)/MktCap_NASDAQ(genesis) + 0.5 × MktCap_Crypto(t)/MktCap_Crypto(genesis).

Concentration Cap & Diversification: To ensure DAI20 remains well-diversified and free from single-asset concentration risk, each individual constituent is subject to a 25% weight cap within its own sector leg. If any single NASDAQ-10 company or any Crypto-10 asset would otherwise exceed 25% of that leg's total market cap weight, its weight is capped at 25% and the excess redistributed proportionally across the remaining constituents in that leg. This means no single stock or coin can represent more than 12.5% of the overall DAI20 basket (25% of a 50% leg), preserving the structural diversity that underpins the index's design.
