What changed in the last 30 days
Oct 12Rep. Gilbert Cisneros sold $15K to $50K, disclosed 14 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.
Oct 2Group President, AMG & ISG GOPALSWAMY SUDHIR sold $1.2M 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 GOPALSWAMY SUDHIR filed to sell $1.2M 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.
