And this is again an obviously naive assumption. Your average developer at Apple has no idea how many iPhones Apple sold in China. Nor do Nvidia employees they know how many GPUs NVidia sold. Your random Amazon developer didn’t know Jassy was going to announce at the earnings call that Amazon was going to announce that they were going to spend more this year on Capex for AI related hardware than they’d free cash flow tanking their stock.

Again, I worked at AWS and we had no insider knowledge

> but for say Nvidia or Apple I would assume the employees would be a good people to take the stock advice from

Isn't Apple pretty famously secretive even internally around stuff like product launches? I would expect a company that runs a tight ship to have rank-and-file employees who would have less potentially actionable info than ones at companies that don't control information as well.

In a tiny company this is true. In any medium (much less large) company you don't know much more than anyone else on the street - and the independent analysts who just watch public information closely usually know more than you do about all that. (it is their job to read the data from China and figure out what that means for the companies involved).
