What changed in the last 30 days
Oct 2Chief Technology Officer Woo Raymond sold $119.1K under a 10b5-1 plan (Oct 1)
Why it matters
A 10b5-1 plan schedules trades months ahead, so this says little about what the insider thinks today.
Oct 1Officer Woo Raymond filed to sell $119.1K by Oct 1 (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.
