Union Investment and Baillie Gifford are among the latest batch of new members named by US buyside trading platform Luminex, a sign of EU managers' appetite to find new ways to source block trades.

Union, one of Germany's largest asset managers with €252 billion under management, and the Edinburgh-based manager Baillie Gifford, which has assets under management of £110 billion, were named in a revised member list published on Luminex's website on February 16.
