Reminiscences of spring and summer of ‘87

Here is an interesting video of Art Cashin, director of floor operations at UBS Financial Services. I hadn't heard about him before, but he's making sense in this interview.
The most important quote is:

“There’s just some eerie things about this—it’s reminiscent of spring and summer of ‘87 when nobody believed the rally and it kept going up despite skepticism, people shorting into it. It ate them alive until it suddenly turned.”
