A year on, we haven’t absorbed the lessons of the GameStop saga

This time last year I walked into the offices of a car rental company in Queens, New York, to hire a vehicle. Quite unexpectedly, I ended up in a rather animated debate, not about the sky-high price of rental insurance contracts but about share prices.

As I filled in my forms, I let slip that I was a financial journalist. Before I knew it, I was bombarded with questions from the staff — and even other customers — about the share price of an electronics retailer called GameStop.
