Financial expert Jim Cramer appeared on the Today Show yesterday and urged investors to take what some might deem as dramatic measures to protect their investments in a tumultuous stock market.

“I thought about this all weekend,” Cramer told [NBC's Ann] Curry. “I do not want to say these things on TV.

“Whatever money you may need for the next five years, please take it out of the stock market right now, this week. I do not believe that you should risk those assets in the stock market right now.”

Cramer, who came to these conclusions by calculating individual Dow stocks and estimating how far they might yet fall, believes the bank lending default crisis could bring “as much as a 20 percent decrease in the stock market.”

But what about those of us with more than five years and plenty of assets? According to Cramer, “I think what you have to do, if you can withstand it, is just ride it out.”
