Two more facts: 1. He sold about 80% of his hold
Post# of 148294
1. He sold about 80% of his holdings. Sold 1.1 million shares. Has 284,000 remaining.
2. None were near expiring. Earliest expiration was Feb 2023. Many others much later (bottom half of the form).
Speculation.....the 284,000 he didn't sell are not yet vested.
