If you are underweight oil and natural gas stocks, get ready to buy them next week, James Cramer said on his "RealMoney" radio show Thursday.

Oil and gas stocks are coming down, and Cramer believes most individual investors are still underweight oil and gas. That tells him the move isn't over, he said.

Cramer recommends buying "intermediate" natural gas and oil companies that "can still be nimble enough that a big find means something." His favorites are EnCana ( ECA - Get Report), Cimarex ( XEC - Get Report), Chesapeake Energy ( CHK - Get Report) and XTO Energy . He also likes drilling supplier National Oilwell Varco ( NOV - Get Report) and would even consider majors like ConocoPhillips ( COP - Get Report) and Chevron ( CVX - Get Report).

Commenting on Sears Holdings ( SHLD), Cramer said Sears director Steve Mnuchin bought 265,000 shares of Sears Tuesday and Wednesday on the open market, thus reinforcing Cramer's long-term bullishness on the stock.

In response to a question about KB Home ( KBH - Get Report), Cramer said he would sell KBH, adding that he is bearish on homebuilder stocks in general.

Cramer said he is "sticking by" St. Joe ( JOE - Get Report). He knows the company well, has walked the company's land in Florida and is not in the stock for a trade.

Cramer said he made a mistake recommending Annaly Mortgage Management ( NLY - Get Report), which has fallen to about $13 from roughly $20. Cramer believes the stock is headed for $10, and he would look to buy it there. The company "got thrown through the windshield" by the Federal Reserve's tightening of interest rates, he said.

In his weekly "Stump Cramer" segment, Cramer was intrigued by StoneMor Partners ( STON - Get Report) and Willis Lease Finance ( WLFC - Get Report).

In response to a question about Brazilian stocks, Cramer was bullish, saying Brazil is "the real deal."

A caller asked if the "Cramer Tech Rally" included Zoran . Cramer said Zoran is in the "sweet spot," but he once had a bad experience with the stock when the company announced accounting irregularities. That "burned me too much," he said, adding that he doesn't trust the company.

Cramer is cautious on Corning ( GLW - Get Report), due to a report of a big screen TV glut. Although he doesn't believe the report, his favorite area of the tech rally is cell phones.

In response to a question about PetroQuest Energy ( PQUE), which Cramer identified Tuesday on his "Mad Money" TV show as a potential takeover play, Cramer said the stock had moved beyond where it should be. He would look to buy the stock below its recent $10.25. "If it doesn't get to $9, I would take a pass," he said, adding he now prefers fellow independent Gulf oil and gas takeover play Newfield Exploration ( NFX).

Finally, Cramer reiterated his bullishness on Lucent , saying if Lucent gets the orders he expects from Cingular and BellSouth the stock goes to $4. If not, it probably goes lower, he said. Lucent fetched $3.05 Thursday.

At the time of publication, Cramer was long EnCana, Cimarex, St. Joe, Lucent and Sears.
