In 2005, Sandy warned investors about a coming property market crash. He made his forecast at various speaking events in China, New York, and Dubai.
Over 5500 people attended, listened and Sandy was invited back to China once he was proven right again.
Eight weeks later, that market crashed.
In July 2015, Sandy warned investors on CNBC that something big would happen on August 18.
"Be prepared to bank profits and stand aside." He said.
Come August 18, the Dow Jones Index lost 2,198 points (-12.5%) in four trading days.
Next, Sandy told CNBC on August 28, 2015, that "there would be a further decline commencing on September 14 or 17, 2015.
And again, the Dow Jones fell 991 points (-5.8%) over eight trading days.
