If all the hydraulic fluid is draining out of the brake system, pulling on the handbrake (going from a decade of zirp to 7% in a week) is going to have an effect but that does not mean I think you can tap on the brake pedal and get the fine control you think you can.

I agree Most tech companies have been spewing capital out the door and funding the lucky RSU / optioned employees for a decade. I guess the weird hiring practises and so on have been hiding that reality. I think shareholders are waking up to it, but zirp is only a small part of the story
