My attempt to answer your question is along the lines that I posted on another thread:
On Wednesday morning on the LSE, Pensana started to follow the ASX further down and early on it flirted with 58p, then after 9am there was an intraday turnaround as Pensana on LSE swung around and headed back upwards with a daily volume 8 times greater than Tuesday.
My guess is that someone in the UK got Pensana through their investment committee meeting either on Tuesday London time or first thing on London's Wednesday morning.
There are many positive factors for REs in general and Pensana in particular currently: + increasing attention to rare earths, + rising product prices, + UK and European government green energy and ESG moves, + Pensana's move to the big-boys SETS trading on the LSE, + Liberum probably waving the flag of Pensana profit estimates with the UK instos, + expected growing profit margins in the BFS in progress.
