Ann: Appendix 4C - Quarterly Report, page-121

Yesterday's run priced in the potential for the GE deal to be released. Lot's of short-term traders rushing in hoping for 100%+ gains... When that didn't happen, they sold so they can park their money in the next shiny bet. If you look at where OSP closed for the past 2 weeks (not including yesterday) you'll notice that SP has already recovered to it's floor of 4.5 - 4.9c (just below resistance of 5c). It'll likely sit there for the forseeable future until the deal gets executed. Which is when those same traders will come rushing in at a much higher SP.

Of course this is all IMO.
