PR Newswire add limits to data

ALBANY, N.Y. — PR Newswire, which distributes announcements and press releases about earnings and other business developments, said Wednesday that it will require recipients of its primary feed of information to certify that they won’t use the data in high-frequency trading.

The company said it is also recommending that clients intending to release information at the close of the markets do so at 4:01 p.m., to ensure that high-frequency traders can’t trade on the news in the milliseconds after the closing bell at major US stock exchanges.

Chief executive Ninan Chacko said PR Newswire, since its inception, has worked to establish practices to provide news to shareholders and the public equitably.


High-frequency traders can use information in the milliseconds before it becomes available to other investors, ‘‘effectively skimming from the rest of the investing public,’’ said New York Attorney General Eric Schneiderman.
