LUMEXA IMAGING HOLDINGS INC

The top of the register is anchored by active managers rather than index funds. AllianceBernstein leads at about $55 million — roughly 21% of the disclosed book — followed by Massachusetts Financial Services ($20M) and Janus Henderson ($18M). All three are fundamental institutions, which gives the LMRI book a different character from index-driven micro-caps.

For readers, the signal is real institutional engagement: three sizable active managers anchoring an 81-holder base suggests professional investors are building conviction in the imaging name. The AllianceBernstein lead is the position to track as the bellwether of that interest.
