not really, My guess is that only those who bought in the first 2 hours were covering. Some others have covered themselves with options probably. what RFMd would need right now is the PR that they will widely beat the expectations. That would really make a very nice short squeeze.
The fact TQNT has completely shut down Texas newly installed 6" line due to no orders is a good indication RFMd has increased market share by a signifiact amount. I would think TQNT would need to announce that soon and this could give the rotation from there to here givng us that short squeeze.
