The rumor started yesterday (Friday): Microsoft was on the verge of buying Adobe right off the market. The Adobe stock price shot up by 17% during the day (triggering an automated circuit-breaker to stop pricing), after the announcement of a meeting between Microsoft Chief Executive Officer (CEO) Steve Ballmer and Adobe CEO Shantanu Narayen.
But the rumor seems already blown out with analysts remarking that the anti-trust authorities of many a country would find reason for investigation and that the expected gains from a simple purchasing are not as high as those coming from a technical and commercial cooperation which would be much easier to setup.
