On a day marked by superstition, analysts share their worst fears with CNBC.
It's the second Friday this year that falls on the 13th of the month – 13 is perceived as an unlucky number in many countries. And for the strategists interviewed from around the world, fears at the top of their lists ranged from skydiving with a parachute full of spiders to seeing a repeat of the global financial crisis of 2008.

"It's jumping out of a plane and having the parachute open, but the parachute is filled with spiders that crawl over me as I drift into a pool populated by sharks with laser beams on their heads," said Dan Greenhaus, chief global strategist at BTIG, an investment firm New York, speaking about his greatest fear on CNBC Asia's "Squawk Box."
For Sydney-based FOREX.com Research Analyst Chris Tedder, the biggest dread centered on sea monsters keeping him away from his day job.
"I didn't use to be afraid of the ocean, but I had a nightmare last night that I was stuck in the ocean and there were talking sea monsters and they wouldn't let me go home and trade the markets, so that's sticking with me today," he said.
In a sign that superstition continues to run deep in modern society, the U.K.'s Daily Mirror newspaper reported that a third of Brits say they would prefer to hide under the duvet this Friday 13 and emerge the following day to avoid bad luck.
According to the Stress Management Center and Phobia Institute in Asheville, North Carolina, some 21 million people in the U.S. fear Friday the 13th, resulting in between $800 million to $900 million in lost business each time the 13th falls on Friday, media reported.
