What changed in the last 30 days
Oct 19President & CEO SMITH GARY B sold $2.1M under a 10b5-1 plan (2 trades, Oct 1 to Oct 15)
Why it matters
A 10b5-1 plan schedules trades months ahead, so this says little about what the insider thinks today.
Oct 15Officer Gary B. Smith filed to sell $5.3M by Oct 15 (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 6EVP & Chief Customer Officer Phipps Jason sold $933.8K 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.
