When people look at the market, they think of technology, Cramer told listeners of his

"RealMoney" radio show Friday.

But technology stocks are news-driven stocks, he said. He urged his listeners to sell technology before the summer as nothing new comes out in the summer.

"The semiconductor industry is the single worst place to be right now," he said. "Every summer I have been in this business the technology industry has been down, so why should it be any different now?"

PC sales are down and inventory in this sector is piling up, Cramer said. The only stock Cramer said he likes right now in the sector is

Apple Computer

(AAPL) - Get Report

.

Otherwise, Cramer advised listeners to sell technology stocks every time there is a rally in the sector.

"

Right now the oil, mining and infrastructure industries make sense to me," he said. "Wait until August to buy technology."

In the midst of all the

Federal Reserve

tightening, banks have been doing well, Cramer said. This tells us the Fed might be finished raising rates.

"I believe that the bank sector is doing well is a good sign," Cramer said. "They've been great predictors of what's to come."

Test Pattern

The market runs in patterns, Cramer said. It can tell you when it is time to buy and when it's time to sell.

Friday is a textbook day, Cramer said. The market rallied

early because Europe did, and Europe rallied because we did. Then the market went down, he said.

"I like to only buy a stock when I can see the white in its eyes," he said.

"If you missed the opportunity to buy the stock yesterday you have to wait," Cramer said. "Just watch it and be patient."

"I like to buy the one or two stocks that did not rally," he said, adding that he believes any company that is in the machinery business could do well. Cramer also told listeners to take a look at the oil or supermarkets.

If you stay in machinery, oil or supermarkets you should be fine, but there are some consumer stocks that are being given up, he said.

Not Quite, Qualcomm

The first caller asked about

Qualcomm

(QCOM) - Get Report

, which Cramer owns for his charitable trust

Action Alerts PLUS.

Cramer advised the caller to respect what the market was trying to say. Here, it's saying that Qualcomm is not finished going down. Wait until it goes two points lower to buy, Cramer said.

Cramer told his next caller to wait before buying railcar company

Westinghouse Air Brake Technologies

(WAB) - Get Report

. It is in the midst of transitioning from a momentum stock to a value stock, he said. Right now, Cramer said, it did not have a risk/reward ratio he cared for.

Instead, he recommended

Norfolk Southern

(NSC) - Get Report

to the caller. It has a better and clearer path to go higher, he said.

Cramer told a caller to be careful about

Oregon Steel Mills

( OS), saying that although it was one of the hottest stocks at the beginning of the year, right now it does not have a good risk/reward.

When the next caller asked about

Coca-Cola

(KO) - Get Report

, Cramer said that although Bear Stearns upgraded the company, he believes

Pepsi

(PEP) - Get Report

is a better stock.

Even though Pepsi is more expensive than Coca-Cola, Pepsi has performed better, and it has better growth, Cramer said. He recommended the caller swap out of Coca-Cola and into Pepsi.

Cramer advised a caller to pick at

Schlumberger

(SLB) - Get Report

, since right now the stock is in virtual freefall.

"I would buy 50 out of 200 shares right now and wait to buy 50 more shares as it drifts down, and then I would buy 100 shares," Cramer said.

Cramer preferred

Consolidated Edison

(ED) - Get Report

to

Public Service Enterprise Group

(PEG) - Get Report

.

And he recommended

Qwest Communications

(Q)

to a caller over

Level 3 Communications

(LVLT)

. Level 3 needs to stop making acquisitions, they are killing their shareholders, he said.

Cramer said

Starbucks

(SBUX) - Get Report

and

Whole Foods Market

( WFMI) are his two favorite growth stocks.

And he told a caller to wait on purchasing

Peabody Energy

(BTU) - Get Report

.

At the time of publication, Cramer was long Qualcomm.
