It's good to see BSP's share price rise on a pretty significant volume on the day before (09/10/2015) and the day of (12/10/2015) the TNP announcement regarding the possible acquisition. It was only a 5% rise, but at least it was was a rise with reasonable volume, and that rise has been sustained.
If news of the potential acquisition did cause the BSB's price to rise, it's good to see HK investors getting behind the deal already.
