How this was made
The 30-second read
Why it matters
The newest fact is the specific open-market sale size, price, and that it was executed under a pre-arranged 10b5-1 plan.
Market read
Traders may note the insider sale for sentiment/positioning, but the 10b5-1 structure limits fundamental inference.
What to watch
