Until the

Fed

meets, the market is going to continue bouncing up and down, Jim Cramer said on his

"RealMoney" radio show Tuesday.

Analysts who say there won't be any bounces are wrong, he said. It is difficult to decipher how strong the bounce will be or how long it might last, but it will occur, Cramer said.

The pattern of the market keeps changing day to day because people are switching in and out of funds. Unfortunately, the homework and research Cramer talks about doing before buying a stock does not seem to matter in this type of environment, he said.

For example,

National Oilwell Varco

(NOV) - Get Report

, an oil management company, is fully booked up, but the stock is getting hammered, Cramer said.

But Varco is not the only stock that's going down, he said. Companies that make equipment for Varco, such as

Dresser-Rand Group

(DRC)

are also plummeting. Although the company's order books are filled, its stock was at its 52-week low last week, Cramer said.

URS

(URS)

, which Cramer owns for his charitable trust

Action Alerts PLUS, is another company that is not where it should be, he said. The stock is trading at $39 from $49 four weeks ago.

It is the No. 1 pollution services company that Cramer said he follows, and in addition, the industry is "rocking," he said.

Foster Wheeler

(FWLT)

, which Cramer also owns for his charitable trust,

Home Depot

(HD) - Get Report

and

General Mills

(GIS) - Get Report

are three other companies that Cramer said are doing well and are surprisingly down.

However, there is a lesson people can learn from this, he said. It is not easy to pick stocks under bounce scenarios. And people must understand that the fundamentals of the companies are not swayed by the bounces, he said.
