Yes, it's all the shares outstanding. But Apple will own a trivial number, the majority that they've bought back will have either been retired or given to employees as bonuses, so they don't own them any more. They'll only own those that they are temporarily holding for future award to employees.
I disagree. Everything Frosty says is part of his overall tactic of disrupting threads into his narrative of Apple being in trouble because Tim Cook isn't Steve Jobs and supports the wrong politics, and is distracted by rainbows, and the Watch is ugly, and whine whine whine Christmas. He's an attention-seeking whiny troll, with every single damn post. About time he was banned.
