Look no further than the more than 400 point pounding on Monday for proof. Nenner says,

"If we see a good close on the S&P futures for March below 3230, that's only a couple of points away from here. Then we get lower price targets, and then this could turn into something much more serious...

These bull markets don't stop on a dime. So, we can go up and down and up and down...

People always think there is a buying opportunity... but this market will go down in a strong, strong way."

Nenner is not waiting. He is instructing his clients that "It's time to sell. We are totally out of stocks..."

"There is a difference between insiders and small investors. Small investors are upset if they miss another two or three percent to the upside, while the big investor is afraid they can lose 40% to the downside. I am afraid they can lose 40% to the downside. I am standing aside unless I see something totally different."
