Fair Play Measured in Slivers of a Second

On Friday morning, Thomson Reuters released the latest University of Michigan Consumer Sentiment Index, as it does twice a month. But this time was different. As a result of a settlement Thomson Reuters reached this week with New York’s attorney general, Eric T. Schneiderman, a select group of its customers didn’t get the two-second advance release they’d been buying. …

The University of Michigan index falls into a broad category of private data that can move markets, or stocks in individual companies. …

All of this raises the question: Should everyone have access to market moving information at the same time? It turns out the answer is hardly self-evident. [cont.]
