Each week, I receive feedback from readers and sources about Wall Street’s biggest characters and concerns. I’ll be engaging with some of those questions here—in addition to a few observations of my own.

Bill, do you think Elon will keep selling? And that the Tesla stock will remain steady?

He’s playing with house money, so it’s doubtful Elon Musk cares very much what happens to the stock price if he happens to sell some shares from time to time. He’s worth around $290 billion at the moment. And, let’s face it, Tesla is a meme stock, completely untethered from the company’s financial performance. If Tesla’s price action were the slightest bit correlated to its income statements, then as my friend Scott Galloway told me recently, one could expect Tesla stock to fall 80 percent or more “pretty crisply” given its momentum-driven, 16-fold increase over the past two years.
