"I still think there's a lot of money to be made in tech," Jim Cramer told viewers of his "Mad Money" TV show Thursday. "But you need to think harder and work harder."

He said that Intel ( INTC) is "no longer sitting on top of the world," and that even though he still likes Broadcom ( BRCM) and Marvell ( MRVL), the companies have run higher and "the easy money is in."

For greener pastures, he said to take a look at SiRF Technology ( SIRF) because "when you bust open gadgets, there's money inside."

After looking inside of Garmin's ( GRMN) new global positioning system device, Cramer found a chip from SiRF, and as the price of GPS comes down he believes the market will expand.

Cramer cautioned, however, that you'll only make money in SiRF "if you're willing to be disciplined and patient." That means waiting for weakness in the stock to buy and gradually building a position over time. "Buying all at once is the sin of arrogance," he said.

He believes that we'll soon see more GPS systems in cars and in cell phones. So even though only 18% of SiRF's revenue comes from cell phones, he believes that segment could grow at a 50% clip.

He said the GPS-in-cell-phone market will be so big that there will be room for both SiRF and Qualcomm ( QCOM), which currently leads the way in GPS chips for cell phones. Cramer owns Qualcomm for his ActionAlerts PLUS charitable trust.

Deutsch Solar Power

SolarWorld stock is coming to America, but Cramer said to "pimp over to Germany and buy it there first ... before it comes to us."

That's because he believes the stock will soar once it starts trading in the U.S.; so he wants to get it before it jumps.

"It's the Exxon Mobil of solar power," he said, referring to the fact that it is one of the more mature and successful companies in the nascent solar industry.

Compared with its peers, it trades at a premium, he admitted. But that's because it is profitable and well positioned.

This isn't just for a trade, he said, since everyone understands oil isn't going down to $20 a barrel ever again and that alternatives need to be found.

The Germans spend more on solar power subsidies than anyone else, so this will boost SolarWorld, he said, adding that the company is increasing its silicon wafer production and recycling its silicon, which is in short supply worldwide.

Beware Fast-Drawl Trading

Cramer said that Wall Street is like the wild West. And as Dirty Harry said, a good man needs to have a sense of his own limitations.

"There are times when you won't make money ... when you'll get eaten," he said. And that's why he said to stay out of after-hours trading.

He used Bristol-Myers ( BMY) as an example. Two days ago it announced after hours that it had settled its Plavix litigation.

If you tried to get in right after the good news was announced, you got creamed by guys who are "sharpshooters," he said. There's not enough stock out there after hours, and you're competing with the best and most ruthless traders in the business to get it.

You have to wait for weakness the next day, or even two weeks after the good news, he said. "Otherwise, the professionals will eat you alive."

Cramer walked viewers through the Bristol after-hours timeline from that evening. The stock was at $22.80, just before the news, he said, and by 4:33:12 ET, the stock was up a dime at $22.90.

By 4:33:39, it was at $23.70. By 4:34:15, it was at $24.22.

"That was it," he said. In only four minutes the easy money had been made, and the price moved on only 7,000 shares. "You'll never be fast enough," he said.

Hibbett's Room to Play

Whenever Cramer sees a regional-to-national retail story, he sees money in the bank, and he sees that potential in Hibbett Sporting Goods ( HIBB).

The company's chief executive Michael Newsome told Cramer that Hibbett may not need to expand nationally in the near term in order to accelerate growth.

Hibbett is concentrated in a 22-state area in the nation's Sunbelt, Newsome said, and his company has identified 400 markets in that region alone where there is room to expand.

It will be several years before Hibbett need go beyond that region, those borders, Newsome told Cramer.

Cramer said that he's seen Dick's Sporting Goods ( DKS) and The Sports Authority ( TSA) have not done well. "How good is the sporting goods industry," he asked.

Newsome said the industry is healthy, and that Hibbett only expands in areas where they are needed and have little competition.

Despite the fact that the stock has seen some trouble, he added that there is good demand for Under Armour ( UARM) products in his stores, as well as for Nike ( NKE) shoes.
