Oct 6See Remarks Assaderaghi Fariborz sold $963.2K under a 10b5-1 plan (Oct 2)
Why it matters
A 10b5-1 plan schedules trades months ahead, so this says little about what the insider thinks today.
Oct 2Officer FARIBORZ ASSADERAGHI filed to sell $932.8K by Oct 2 (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.
