Because the story had been all over Twitter and Facebook and other forums for hours. It also has shown up in my email alerts for the search term "InterDigital".
Because it was released over 2 hours ago by DealReporter and already had its effect. Remember when the price went down $2 in 60 seconds? That was when the story came out.
Because when 2.6 million shares get traded in IDCC, a post on iHub (which gets a lot less eyeballs than Twitter) isn't going to have an impact.
Because I don't censor news because it's positive or negative. When IDCC is mentioned everywhere in a story, it's news.
And finally, because my actions have zero impact on the share price. Especially when I just post information that has already been disseminated all over the internet. To think anything else is sheer lunacy.
