Feuerstein? absolutely not. He didn't but RPC shares.
Garza? probably not. That would mean Garza bought shares after his second round of "bullish coverage" in January 2011. That's not how Garza makes money. He would NOT "buy his own news."
And besides, there will be no award money. Rosen might win -- in fact he will probably win if it goes in front of a jury -- but Radient has zero money to pay an award so there is NOT going to be any money for the members of the class.
If you mean "are those two getting sued?" then the answer is no. Garza in particular has a huge disclaimer stating that he cannot be sued or held responsible for anything he says. That gives him free rein to say ANYTHING.
