Advance News Trading Experiment
The advance news trading experiment is the markets case described in Cockroaches 1, Modi 0: India’s remarkable protests, where participants saw historical next-day newspaper front pages and then traded stocks and bonds. The source says ordinary participants, and even AI models, struggled to turn advance news into strong returns.
The experiment matters because it separates information from investable edge. Participants often misread the Market Expectation Gap - what was new relative to what markets already expected - and then damaged results through poor Position Sizing, leverage, and insufficient abstention.
Expert macro traders did better in the source because they adjusted size sharply with confidence and sometimes chose not to bet. That makes the experiment an applied case for Investment Risk Management, Investment Edge, and Kelly Criterion rather than only a puzzle about prediction.
