What changed in the last 30 days
Oct 9President and CEO Liang Charles sold $4.5M under a 10b5-1 plan (Oct 7)
Why it matters
A 10b5-1 plan schedules trades months ahead, so this says little about what the insider thinks today.
Oct 9Director Liu Liang Chiu-Chu Sara sold $4.5M under a 10b5-1 plan (Oct 7)
Why it matters
A 10b5-1 plan schedules trades months ahead, so this says little about what the insider thinks today.
Oct 7Director Liu Liang Chiu-Chu Sara filed to sell $4.5M by Oct 7 (Form 144)
Why it matters
A Form 144 is a notice of intent to sell; the sale may not happen, and it says nothing about the price.
