It's typical only where there is a huge macroeconomic shock like in 2001 or 2009, or because those large companies were either horribly managed (i.e. outdated business model). None of that is true right now with respect to Tesla...huge increased in oil prices recently should actually make EV's "cheaper" in comparison.
"This happens all the time" at badly managed companies, or perhaps at well managed companies if there is a huge macroeconomic shock like in 2001 or 2009. Given that great software is what supposedly gives Tesla its competitive advantage, it's really bizarre to me to go from having 20 open software dev positions to a layoff within 48 hours, because Elon Musk "has a very bad feeling" based on no new data points as far as we can tell. Unless he learned something this week that he isn't telling us.
OP is discussing his prediction about the economy though.
