It's possbile that the restate had to raise cash so it sold everything. It's also possible that the beneficiaries sold the stock because they may not have a background in equities (or in IDND in particular) and would rather have the cash to buy something they understood, needed or wanted to own instead.(like a teenager wanting to buy a car etc). There are lots of reasons.
I'm here too : ) The other day, I heard a rumor from a source that I consider very credible that there has been a large estate selling. Maybe that's done? Anyone know of any large shareholder that has recently deceased?
