(Alliance News) - The JP Jenkins-15, an index of the largest companies listed on the UK share dealing platform, rose in May after a slight decline in April, JP Jenkins said on Tuesday.
The index stood at 1,297.16 points on May 29, up 4.2% from 1,244.65 on May 1, having slipped 0.3% in April. It is up 30% from its baseline of 1,000 points at the start of 2025.
London-based JP Jenkins provides a matched bargain platform for unlisted companies.
JP Jenkins said an allotment of new equity by Omega Minerals PLC helped lift the index. Omega, which has a market capitalisation of GBP596.5 million, listed on JP Jenkins in January last year.
Late last month, Nanoco Group PLC said it plans to de-list from the London Main Market but will make its shares available on JP Jenkins.
The next JP Jenkins-15 index calculation will be based on closing valuations on July 3.
