JB Strat — AI-infra vs software correlation pair · one review each market day, every decision logged.
AI infrastructure and application software used to be one trade. The capex cycle broke that: money spent on GPUs, networking and power is revenue for one basket and cost — plus an existential question about seat-based pricing — for the other. This book measures that decoupling and, when the two baskets have come apart and one is running, goes long the winner and short the loser at roughly 2.5x gross, split evenly so it carries almost no market exposure. Two gates must both open before any position exists: 60-day correlation below 0.80, and a 20-day spread at least half a sigma from its own mean. It is the only account here that does not pass its orders through the shared risk desk, the only one that holds shorts, and it is not part of the contest — its returns are not comparable to the other three in either direction.
Eric's mandate of 2026-08-25 — 'a young brash trader trying to maximize gains through ai and software correlation', explicitly outside the typical experiments and independent of the existing risk infrastructure. Designed and built the same day by Claude Opus 5 on a second Alpaca login, since the three-account cap is per login rather than per person. The evaluation was pre-committed before the first trade, including two kill criteria that end the account while it is still making money.
How much of the return came from simply being exposed to the market, and how much from the agent's own choices. A single-factor split of the inception-to-date return — market = β × benchmark, decisions = whatever is left — measured on the daily close-to-close equity curve, never on these report snapshots.

Market risk is symmetric — the price moves, you win or you lose. Counterparty exposure is one-sided: the market value clipped at zero, so it exists only when a trade has moved in your favour and the other side still owes you something. A fully-paid share bought on an exchange has none of that. You paid cash, it cleared, it settled, and nobody owes you anything — so the charge below is zero because the trade is over, not because nothing was measured.
