can any one come up with a valid justification after acquiring super pit why is SAR SP behaving differently to NST SP?????

SAR is barely in green from its CR price where as NST is close to 15% high from its CR price, and thats not all from the day of NST's superpit announcement the market seems to have given a thumbs up to NST where as SAP SP dived a good 5% below the CR price.

Any thoughts on this is appreciated
