 Todays results from London Stock Exchange Group PLC take some of the pressure off management as it struggles to justify its 20bn acquisition of capital markets data provider Refinitiv. The shares are up 5.8 at 7,904p today but thats a long way south of the 9.488p they were trading at on 4 March, the day before the group released its full-year results and more pertinently opened up a can of worms by revealing the expenditure that would be required to get Refinitivs technology platform up to speed.
