The number of shares dumped is irrelevant. According to disclosures Alper and his kids let their businesses be acquired in exchange for stock. It could even be them that are slowly unloading these past few days...no one knows. Regardless, any amount of trading based on inside info is always illegal.
As with most others, the PR about his new "advisory board" didn't do much to lift the stock. Alper stated he expects to file Q2 by 7/19 ...within the next 10 days.
