Let go of the past, Jim Cramer told listeners Friday on his "RealMoney" radio show.

Tech stalwarts such as Dell ( DELL), Cisco ( CSCO), Sun Microsystems ( SUNW) and Oracle ( ORCL) have seen their best years, he said, and it's time to move on to find the next Dell, the next Cicso, the next Sun and the next Oracle.

What these stocks have in common is little to no growth, said Cramer, and growth is what Wall Street likes. So, waiting for a better time to sell means capital is being tied up when it could be redeployed elsewhere. There are so many stocks that are better, said Cramer. "It makes no sense to hold them."

If you have to, sell small amounts over time, he said, until the positions are gone. You can always buy them back if something changes, he said.

Cramer likes Intel ( INTC) and Microsoft ( MSFT) better than Dell. Broadcom ( BRCM) is better than Cisco, he said. Cramer would rather own SAP ( SAP) or Microsoft than Oracle. As for Sun Microsystems, that "sector is dead," he said.

Cramer, Unstumped

Stocks Under $10 co-author David Peltier joined Cramer to talk about stocks from Thursday's "Stump Cramer" segment.

Of HMS Holdings ( HMSY), Peltier said he preferred Allscripts Healthcare Solutions ( MDRX). Cramer agreed.

Peltier said MainSource Financial Group ( MSFG) lost its CFO in October, and he would wait to see "how the new CFO does."

Cramer agreed, saying the CFO's departure is "perhaps a red flag."

Peltier said Anadys Pharmaceuticals ( ANDS) was well-capitalized with enough cash to last four years. But the company only had $2 million in revenue last quarter and is just beginning human trials, he said. The stock is up big this year, so it could be a risky situation.

Cramer said Anadys sounded interesting, and he recommended monitoring the situation for further developments in the human trials.

Peltier likes Landec ( LNDC) because he sees the company benefiting from the growth of packaging for supermarket fresh-cut fruit and vegetables. It's not the cheapest stock in the world, he said, but the company has demonstrated 60% earnings growth each year for the past three years, he said. Peltier believes Landec could get to $8 to $10 over time. Landec traded at $7.79 late Friday.

Cramer said the stock "sounded like a buy."

Of Prana Biotechnology ( PRAN), Peltier said it was the one stock "I'd definitely give a buzzer to." The company has no revenue, he said, and although it has $21 million in cash, it is burning through cash at a rate of $30 million a year, he said. It's likely Prana will need to do a secondary offering, he said. If you really want to buy the stock, wait for the secondary, he said.

Cramer recommended taking a pass on Prana.

Finally, Peltier said Dynegy ( DYN) is a stock in the Stocks Under $10 newsletter that he particularly likes. He believes Dynegy is turning its business around, and he does not believe the stock will continue to trade in the $4 range much longer. Dynegy traded at $4.77 late Friday.

Cramer's Callers

Cramer said talk of CVS ( CVS) acquiring Albertson's ( ABS) pharmacies would be a red flag for CVS. CVS recently acquired Eckerd, and another acquisition would further raise suspicions there "isn't the kind of natural growth in this industry" that there once was, he said.

Cramer would recommend swapping out of CVS into Walgreen ( WAG), which he believes will soon take out its 52-week high of $49.01. Walgreen traded at $46.94 late Friday.

Lightning Round

Bullish

Cramer was bullish on Mittal Steel ( MT), Cigna ( CI), UnitedHealth Group ( UNH), W. P. Carey ( WPC), Texas Instruments ( TXN), Schering-Plough ( SGP) and Nelnet ( NNI).

Cramer was bearish on DreamWorks Animation ( DWA), RadioShack ( RSH), Anadarko Petroleum ( APC), Impac Mortgage Holdings ( IMH) and Pfizer ( PFE).

At the time of publication, Cramer was long Intel, Microsoft, Schering-Plough and UnitedHealth Group.
