That's not insider info necessarily.  Insider info would be if the
stock was rising and there was NO chatter.  The chatter itself is
making the stock rise, just like when there is chatter that Microsoft
will buy Yahoo.  Doesn't mean it will actually happen, and when the
chatter stops the stock will go back down.  That said, DNA is
something of a merger arbitrage play, and is prone to the "chatter"
you're talking about.  In fact, pretty much any biotech stock will be
prone to acquisition or new drug FDA approval chatter, so you might
want to stay out of the industry entirely.
