The London Stock Exchange Group revealed today that it was investigating a lengthy outage at its newly-acquired Refinitiv market data unit.
The outage at Refinitiv’s Eikon platform for market prices began around 0730 GMT. Subscribers who rely on its data for trading currencies and other assets, said on Twitter they were unable to access prices.
LSEG completed its $27 billion purchase of Refinitiv on Jan 29. Analysts had already expressed concerns last month that integration costs will be heavier and cover a longer period than had been expected.
Its shares have fallen 20% so far this year.
LSE shares were up 1.07% at 08:59 GMT according to prices on Yahoo.
