Oct 16Sr. Vice President Cunningham Paul sold $648.3K under a 10b5-1 plan (Oct 15)
Why it matters
A 10b5-1 plan schedules trades months ahead, so this says little about what the insider thinks today.

Oct 1Director SANGIOVANNI VINCENTELLI ALBERTO filed to sell $437.6K 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.
