What The Latest Weekly Result Shows

Context generated from the scored weekly round, including consensus performance, oracle comparison, and benchmark difficulty.

Consensus PerformanceAug 27-Sep 4

AI consensus portfolio scored 10.2 versus the oracle

If the weekly model allocations were averaged into one consensus portfolio, it returned +0.97% versus +0.11% for the S&P 500 and +9.45% for the hindsight best asset.

Consensus means the average of model allocations in the same round. CapitalBench Score compares that return with the hindsight-best eligible asset for that exact scoring window.

High confidenceMath: deterministicData through Sep 4, 2026

Consensus Portfolio Return: +0.97%
Average Model Return: +0.97%
Consensus Capitalbench Score: 10.2

Benchmark DifficultyAug 27-Sep 4

Weekly round had +13.95% asset dispersion

The best scored asset returned +9.45%, the worst returned -4.50%, and +51.43% of the universe was positive. The S&P 500 ranked 32 out of 70 options.

Asset dispersion is the gap between the best and worst eligible assets in the same round. Wider dispersion makes missed allocation choices more costly.

High confidenceMath: deterministicData through Sep 4, 2026

Oracle Return: +9.45%
Worst Asset Return: -4.50%
Positive Universe Share: +51.4%

Oracle ComparisonAug 27-Sep 4

Models found the weekly oracle asset

The hindsight best asset was Crude Oil (USO) at +9.45%. 1 of 7 models held it, with +5.00% average allocation. The largest allocation came from Gemini 3.1 Pro at +35.00%.

Oracle means the best eligible asset in hindsight for that round. Models do not know it when portfolios are frozen.
