Amid the S&P 500 index falling for seven straight weeks and signs of a slowdown in the housing market, billionaire investor Michael Berry posted a cryptic tweet that soured investor sentiment. The businessman famously predicted the 2008 mortgage crisis and became a prototype for one of the characters in the movie “The Downgrade Game.”

“As I said in 2008, it’s like watching a plane crash. It hurts, it’s not fun, and I’m not smiling,” wrote the head of Scion Asset Management.

What exactly Burry meant was unclear, but other Twitter users called on him to indicate whether he thought the current market situation would trigger another financial meltdown similar to the 2008 crisis.

High prices and soaring mortgage rates seem to be cooling a market that has been active for two years. In the U.S., new home sales fell 16.6 percent month-over-month in April, compared with economists’ forecast of a 2 percent decline.

Burry, whose bet against the housing market before the 2008 financial crisis was immortalized in Michael Lewis’s book “The Downgrade Game,” is already accustomed to attracting attention on Twitter. About a year ago, he warned retail investors that “the mother of all crises” was coming to the stock market, but later deleted his post.
