"Disastrous" seems like a significant overstatement.
To me this looks more like "unsurprising". Tesla has some additional business lines which might eventually prove quite valuable, but in the short to medium term it is mostly a car company. The whole car industry is dealing with the results of higher interest rates. It would be much more surprising if Tesla somehow turned out to be immune to that.
It’s below estimates, so it’s by definition “surprising” relative to the people whose business it is to predict these things.
Disastrous may be going too far unless it portends further drops going forward.
But disastrous may also be the right word because Tesla’s valuation is based entirely on massive growth. So even if this means Tesla will start growing fairly normally as opposed to rapidly, that’s bad for Tesla stock.
There is suspicion that Tesla always seemed to just exceed predictions, predictably. I'm sure plenty of people made money when "oh look, another quarter of exceeding expected results".
It was literally under target. That’s the definition of surprising.
It comes as no surprises that the rest of your comment either looks for positives or places the blame on conditions affecting the auto industry at large.
Any reaction to bad news for Elon Musk businesses are outsized for the amount of hate people have for him. I'd say the hate is pretty well-deserved but I also value SpaceX and Tesla tremendously and I hope they continue taking us into the future.
