Marketwired, a company that publishes and distributes corporate earnings and other market-moving news releases, said on Wednesday it will no longer sell them directly to high-frequency trading companies.
The move comes after discussions with the New York attorney general's office, according to a person familiar with the matter, and follows a similar decision by Berkshire Hathaway's Business Wire.
Marketwired said it would no longer provide its distribution service to high frequency trading firms to "eliminate any perceived advantages gained through technology by certain customers,'' according to a statement obtained by Reuters.

A spokesman for the New York Attorney General declined comment.
The decision is the latest response to New York Attorney General Eric Schneiderman's probe of elite traders gaining early access to market-moving information. On Tuesday, Schneiderman announced he was probing services provided by U.S. stock exchanges and alternative trading venues that may give advantages to high-frequency traders.
