> I guess the investors selling NVIDIA's stock like crazy know nothing about jevons
I know you are trying to be sarcastic, but for the sake of argument let's assume that your question is genuine.
There are two types of investors and they both sell, but for different reasons:
1. Casual investors: They don't know much about investing, or Jevons paradox. They only watch the news, so they panic sell.
2. Institutional investors: They know all about Jevons paradox etc, but they also know that casual investors don't, so they sell on purpose so that they can buy the dip later.
