She's just performs trades that fit her best. I don't see it as bullish or bearish. When she digs into her pocket to buy shares at the market that's bullish. Anything else is just noise.
In Jan she was granted 10K shares for $0 In May she sold 1.8K shares for $36K In May she exercised 23K shares for $200K In Oct she sold 11.8K shares for $300K In Nov she exercised 10K shares for $87K In Nov she sold 10K shares for $270K In Dec she exercised 17.5K shares for $152K
Now, show me anything bullish or bearish with that info especially her sales days prior to the trial results.
