Hi Aussiest,
As wg said, it really does depend on the reason for the Trading Halt. An announcement of a juicy takeover battle between multiple suitors will generate far more sp appreciation than say an announcement of an extra $1 billion in bad debts provisioning.
LEI's cap raising may well be OK, depending on how you perceive the ramifications. It highlights the need now for LEI to raise funding from outside its cashflow and the fact that it has a burgeoning order book. I do have concerns that there is little margin for error factored into the calculations. Multiplex stumbled with Wembly and other big players have had their troubles in the past, LEI included if you remember.
Cheers,
Kenny
