(Alliance News) - The JP Jenkins-15, an index of the largest companies listed on the UK share dealing platform, edged down in June after rising in May, JP Jenkins said on Tuesday.
The index stood at 1,264.30 points on July 3, down 2.5% from 1,297.16 on May 29, having risen by 4.2% in May. It remains up 4.6% so far in 2026 and 26% from its baseline of 1,000 points at the start of 2025.
JP Jenkins said the index changes in May and June largely reflected a move in the share price of Omega Minerals PLC, which rose in May and gave some of this back in June. Omega, a gold explorer in British Columbia, Canada, has a market capitalisation of GBP536.8 million, making it one of the largest members of the index.
The index was rebalanced in June. This saw the inclusion of QPlay Ltd, a board game maker that in March became the first listing on the platform to be offered for trading on the Pisces framework. Also joining the JP Jenkins-15 was Bisichi PLC, a miner in South Africa. The two companies replaced in the index were Innovative Power Generation Ltd and OPG Power Ventures PLC.
London-based JP Jenkins provides a matched bargain platform for unlisted companies. It noted that Silver Bullet Data Services Group PLC and CPPGroup PLC will be joining from AIM in the coming weeks.
The next JP Jenkins-15 index calculation will be based on closing valuations on July 31.
