Yes, shorts are fighting hard. But I don't think they'll win this one.
Some short term traders are also taking profits.
89% of float is owned by institutions and they didn't sell at all when we hit 40$ and they won't sell now.
It's not just beating earning expectations - it's massively beating them.
At perhaps EPS at 5, 10$ per share is cash, big growth the share is cheap now - although also risky if Atmel and Cypress can strike back with new products. But for now Synaptics rules.
