'The Great Onion Corner:' Hear how short-selling onions ended with a ban on onion futures

Read about why bans on short selling are a controversial policy

Generally, short selling is legal, but regulations often restrict short positions when a stock has experienced a sharp price decline (more than 10% in one day).
