What changed in the last 30 days
Oct 9Director Dyckerhoff Stefan A sold $4.7M 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 7Affiliate Dyckerhoff Stefan A filed to sell $4.7M 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.
