It appears that Danny Detail's and Blueskywaves' prediction of shares flowing from individuals to institutions is accelerating LOL
Most of us have a nice profit so far - I suppose its not surprising to see some liquidations.
Sometime (soon, i hope) InterDig is will collect hundreds of millions of dollars from Nokia and Samsung for 2G. Also, ahead are 3G licenses with Ericsson/Sony, Nokia, Samsung and many others. After these events, InterDig will likely have $1Billion in the bank; and, depending on the licensing rates for 3G, these events should propel IDCC to $50+.
I'm not real optimistic that these events will happen soon - licensing is a tough business - but they will happen.
So, if you feel like you've missed the boat by not selling, I'd suggest ignoring short term speed bumps that create volatility - EGBOK.
