The short answer is no one knows. Unless you can time travel, maybe. As the old saying goes—predictions are hard, especially about the future. We asked Robert Shiller, author of the book Irrational Exuberance and a 2013 winner of the Nobel Memorial Prize in Economic Science, what he thought.

“It’s hard to know when the bubble will end,” he says. It’s impossible to know if the price will keep going up, and it’s hard to even guess. We also have no idea if going “short” right now, or betting that the price will decline, will be better than going “long,” or betting that the price will continue to go up over time.

So, unfortunately, the unsatisfying answer is the right one: nobody knows.

What you think about it??
