Oh, wow. OK. So we need to go REALLY basic here.
Buy low, sell high, you make money. You with me so far?
So when a stock price crashes, you buy it, then it goes back up later, you've made money. How are you doing up to this point?
Again, though, the important thing to note here is: Vanguard know this. You don't have to. You could have misconceptions about this for the rest of your life for all the difference it makes. What's important here is, Vanguard understands how to make money in this situation. Twitter understands that it protects them from Musk. And Musk should understand it too. He should know better. He should know that this juvenile nonsense has been a complete waste of his time.
