Cramer's 'Mad Money' Follow-Up: Linn Energy

On Wednesday's "Mad Money" show, Jim Cramer said that following mutual funds will help investors know which stocks are headed way higher.

For example, American Growth Fund's biggest position, worth $4 billion, is in Google(GOOG Quote), which Cramer called the "cheapest growth stock I know."

The fund's next largest holding is another tech company, Oracle(ORCL Quote), and its third-largest is Action Alerts PLUS name Cisco (CSCO Quote). Cramer said Cisco could see $23 to $24 a share.

American Growth Fund also owns Apple(AAPL Quote) and Microsoft (MSFT Quote).

Of all of these tech stocks, the only one Cramer said he wouldn't buy is Microsoft. He said that the stocks will benefit from the economic recovery, and American Growth Fund is likely to increase its positions. Cramer told viewers to "tag along and get long."

On Thursday, Google lost 68 cents to close at $396.50. Oracle closed down 37 cents, or 2%, at $18.57, and Cisco lost 50 cents, or 2.7%, to $18.10. Apple shed $1.69, or 1.3%, to close at $124.18, and Microsoft closed down 56 cents, or 2.8%, at $19.82.

Cramer also recommended natural gas play Linn Energy (LINE Quote). Cramer welcomed Michael Linn, the company's chairman and CEO, to the show. Linn said the company has no plans to cut its dividend.

On Thursday, Linn Energy added 86 cents, or 5.1%, to $17.58.

First Niagara(FNFG Quote) has the potential to double or even triple in size this year, said Cramer, and he'd buy it on any weakness.

On Thursday, First Niagara lost 9 cents to close at $11.92.

Geron(GERN Quote), however, was too speculative a play for Cramer in this market.

On Thursday, Geron added 9 cents, or 1.3%, at $6.85.
