Ann: SRG Global secures large-scale infrastructure project, page-17

I was also surprised at the sudden drop for no apparent reason.
Just to note and I'm not sure if it's relevant ACF had exactly the same type of movement today for no obvious reason either.
I wonder if there's a link or if maybe one of the biggies had some poor H/Y results that may have reverberated onto the likes of SRG and ACF?
Thought it was strange though that it happened to both of them within the same hour..  

Your guess is as good as mine Eaglebird you just may have been handed a great opportunity today we will see.. I came very close to jumping in but was thrown by the lack of reasoning for the fall.. 

Does any body else have any thoughts that may put light on today's SP action?
