Market is flying and WRLS is drooping. There were 1mm shares locked up with the SkyBitz acquistion in escrow (although registered and tradeable once the escrow period was over....) that are supposed to be freed up some time around now if certain conditions were met.
In checking the SEC filings, they closed the SkyBitz deal on February 1, 2012 and the escrow as for 13 months OR possibly longer if there were any issues with regard to whatever the escrow related to. Given how strong the market has been I can only surmise that there must be a motivated seller for the stock to have slumped the way it did??
