WWDC is today, any major stock price movement is almost certainly due whatever they are announcing.

Yes, I know, I was tracking the stock while watching WWDC. But there was a very sudden precipitous fall right when this was announced.

We expected to have Apple unveiling world-class local models, and announcement of a framework where you can train and run your models in M4.

And we got a wrapper around ChatGPT 4 + a cloudy-ish dystopian spyware-like copy of Copilot+ that sends your screenshots and activity to a "secure cloud".

I also went to the bathroom around that time, so maybe that had an impact?

It only counts if you're placing buy/sell orders based on your breaks.
