What Happens When Everyone Is a Chinese Stock Market Genius
China's biggest index just took a stomach-churning plunge. Is it a sign of things to come?

Acustomer strolls into a bookstore, goes the popular Chinese joke, and tells the salesperson: “I’m looking for a book with no killers, but much bloodshed; with no love, but great regret; with no spies, but constant paranoia. Can you make a recommendation?” Just one, the salesperson replies: The State of the Chinese Stock Market.
Then there’s this one about a Chinese investor: “In the morning, he watches the K-line graph,” which tracks the perambulations of a share’s price. “In the afternoon, he goes to the hospital to watch his electrocardiogram.”
