So am I right in thinking that LUM now has no sign business, no hole in the ground and no way of generating revenue and yet we have a rising share price: I know im dumb but can someone with more financial knowledge than me “please explain” how this can happen? All I can think of is that someone will use this listed company to save its self a huge amount of cash that’s required to list a business, is this the only play we have????
