But the stock dropped 1% in the seconds after the announcement. This isn’t a 1% drop over the entire day; it’s a 1% drop in 30 seconds after the market has closed. I think it’s safe to say the market values Ive’s contribution to Apple at $9b
That's not "safe to say" at all – markets don't respond well to uncertainty, and SVP-level changes at a company like Apple = uncertainty.
If the company's market value was consistently $9b lower after someone left, then you might make that case.
Assuming the market valuation of this I worth a cent. Which... it probably isn’t.
After hours activity doesn't mean shit.
Ive is worth more like $300B. Easily.
But in the real world he is definitely not the wealthiest person in the world.
