At this stage I am unsure @Beany72 ,
The charts do look suspiciously similar, although PLS are a few more months advanced than RXP.
Regals involvement has not actually been detrimental for PLS (meaning price has not seen serious downside follow through and broken down....so it doesn't seem as though they are attacking them, or their share price........instead it has just moved sideways, with any attempt at a breakout being thwarted, but support coming in each time it appears it might breakdown). So I am not exactly sure what the benefit has been to Regal at this stage (perhaps there is some sort of a covert accumulation going on that will pay big dividends and strongly benefit them at a later stage....and they are playing a very long game).
There is no doubt that Regal have some seriously smart operators running them, they play a strong game, and have proven themselves as very capable operators over a reasonable period of time.
