What changed in the last 30 days
Oct 22Chief Legal Officer & Corp Sec Tregillis Cynthia L sold $306.7K under a 10b5-1 plan (Oct 21)
Why it matters
A 10b5-1 plan schedules trades months ahead, so this says little about what the insider thinks today.
Oct 21Officer CYNTHIA LOCK TREGILLIS filed to sell $306.7K by Oct 21 (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.
Oct 12Rep. Gilbert Cisneros sold $1.0K to $15K, disclosed 24 days after the trade
Why it matters
House members report a bracket, not an exact amount, and have 45 days to do it; the trade is weeks old when it becomes public.
