Three weeks ago,

Network Appliance

(NTAP) - Get Report

, which Jim Cramer owns for his charitable trust

Action Alerts PLUS, reported a fantastic quarter with a positive outlook, Cramer said on his

"RealMoney" radio show Thursday.

Network Appliance stores data, and thus is a company that other companies depend on. Even though it reported a great quarter, the stock dropped a quick 15%, Cramer said.

And the media assumed the company had blown it.

Now Network Appliance's stock is above where it was when the company reported its great quarter.

"You have to get out of the negativity," Cramer advised his listeners. "Don't panic out. The lesson here is, if a stock from a good company is getting hit

for no apparent reason, buy it during the selloff frenzy."

The price of natural gas has ignited, Cramer said. It is time to buy

Chesapeake

(CHK) - Get Report

and

Carrizo

(CRZO) - Get Report

, Cramer said.

He also recommended buying the biggest driller of natural gas,

Nabors Industries

(NBR) - Get Report

, which he owns for his charitable trust

Action Alerts PLUS.
