You may be right about a news coming (related to the May's presentation maybe) but I really doubt that it will affect the SP.
In 99.9% of the time when a good news is coming, it is reflected in the SP before it go out (there is always someone in the known) and there is still no volume or SP increase...
So it will be either
1. No news
2. Air news
3. Bad news
4. Good news that nobody expected (the 0.1%)
I hope for #4 but I really doubt.
