The stock wont take a hit till they either make an announcement to the stock exchange or publish their next results, the prices bounced back due to sporting bets profits, I suspect the average stock market guy isnt logging in every night to see how many customers they have.
I dont see why anyone would take them over now unless they wanted noble poker Party has to my mind made the skins worthless.
This may explain the upsurge
888 came out and said growth is still good in the poker market which is possibly the reason for todays increase. SPorting bet up 6% on the day as well.
