It can turn in a hurry. We saw that happen with TSLA a couple years ago, albeit on a different scale. They were burning through tons of cash and the stock was tanking in 2019 as capital raises were becoming more expensive. Then they hit a couple milestones and the stock turned and voila ... 25-bagger. Granted, a very different situation, but a good example of how quickly things can change when you're in a valuation death spiral.
