Weatherford International (WFT: 17.90 0.00%) rose 2.3% – Cramer feels that Weatherford is the cheapest oil stock around. He recommends that investors buy the stock “aggressively” at its current price around $16.

Prudential (PUK: 23.22 0.00%) gained 3.0% – Cramer is very bullish on the stock and feels the business is “absolutely fabulous”.

Potash (POT: 46.46 0.00%) dropped 0.2% and Terra Nitrogen (TNH: 210.50 0.00%) fell 0.8% – Cramer feels that Terra Nitrogen is a great play on agriculture and he’s sticking with the stock, but prefers Potash given the momentum he’s seeing.

ArcSight (ARST: 0.00 N/A) fell 0.3% – Cramer recommends ArcSight as the top internet security firm for investors given its momentum and growth prospects.

Zhongpin (HOGS: 10.91 0.00%) dropped 0.7% – Cramer remains bearish on Chinese stocks.

Qualcomm
Qualcomm (QCOM: 61.47 0.00%) fell 3.2% after Mr. Cramer called their latest earnings report “an abomination”. Cramer was clearly upset at QCOM’s management for delivering such embarrassing results. The poor guidance was particularly frustrating given the company’s bullish posture 2 weeks ago at the Consumer Electronics show.

Joy Global
Shares of Joy Global (JOYG: 0.00 N/A) and Bucyrus International (BUCY: 0.00 N/A) plunged 2.9% and 5.0% respectively following bearish comments by Jim Cramer. He views the slowdown in China having a negative impact on both stocks. Cramer doesn’t believe the stock has hit bottom yet and cautioned investors to wait to buy this stock.

Deere & Co.
Deere (DE: 88.50 0.00%) stock slid 2.3% after Cramer warned that the stock was headed down in the short term. While Cramer still believes that Deere is a good company, the stock is feeling the negative impact of the slowdown in China. For investors with a 6-9 month outlook the stock will still likely make them money, but in the short-term look for more selling.

Here is a review of the performance of Jim Cramer’s key stock picks from Friday’s Mad Money show.

Goldman Sachs
Goldman Sachs (GS: 116.15 0.00%) stock gained 0.6% today after Cramer forecasted “pain” for the stock in the near term. Cramer believes the financial giant is a great company, but would steer clear of the stock as long President Obama is targeting the Wall Street firm.

Healthcare stocks
Humana (HUM: 85.15 0.00%) fell 2.8% after Cramer put the healthcare stock, along with United Health Group (UNH: 52.14 0.00%) and RehabCare Group (RHB: 0.00 N/A), on the sell block. Cramer acknowledged that the easy money has already been made in these stocks after the huge rallies off their 2009-lows.

Apple
Apple’s stock jumped 2.7% ahead of their quarterly earnings report. Jim Cramer advised investors to start selling the stock now ahead of Wednesday’s release of their much-anticipated tablet pc.

After the close, Apple’s stock was down slightly despite reported blockbuster earnings with revenues jumping 32% over last year.

Cramer’s Lightning Round stock picks:

• Linn Energy(LINE: 36.43 0.00%) dropped 1.9% – Although Cramer has recommended this stock in the past, he doesn’t recommend buying after the stock’s big rally.

• Huntington Bancshares (HBAN: 6.05 0.00%) gained 2.4% – Cramer advised investors to look at HBAN since the stock is “roaring”.

• Webster Financial (WBS: 23.17 0.00%) jumped 6.6% – Cramer prefers this bank stock as they have few bad loans on their books.

Here is a review of the performance of Jim Cramer’s stock picks from Wednesday’s Mad Money show.

Williams Sonoma (WSM: 36.96 0.00%)
The retail stock gained 5.0% today after Cramer’s recommendation on last night’s Mad Money show. Cramer believes that back to school sales are going strong and recommended Williams Sonoma along with Tiffany’s (TIF: 64.01 0.00%), Family Dollar Stores (FDO: 57.48 0.00%) and Ralph Lauren (RL: 171.49 0.00%).

Big Lots (LOTS: 0.00 N/A)
In part 3 of the weeklong series, Jim Cramer profiled Big Lots as a potential candidate to be the next “discount king”. The company has been able to beat Wall Street’s estimates and has increased its 2009 guidance. While same-store sales have been declining, Cramer believes that trends will change by the end of the year. With the stock trading at a discount to peer Costco (COST: 84.28 0.00%), Cramer believes the stock is cheap and recommends buying.

Cramer’s Lightning Round stock picks:

Caterpillar (CAT: 114.04 0.00%) dropped 0.4% – Cramer believes the stock will likely dip back down to $40, but is bullish over the long term.

Kirklands (KIRK: 16.80 0.00%) rose 6.6% – “They put up some good numbers and I think it goes higher.”

Oracle (ORCL: 28.73 0.00%) dropped 0.2% – This tech stock bucked the “Cramer effect” and fell despite a strong buy recommendation from Jim Cramer.

AT&T (T: 30.02 0.00%) fell 0.3% – Cramer feels the telecom stock is going from $25 to $30, but the markets seem to shrug off the recommendation.

Verizon Communications (VZ: 37.92 0.00%) dropped 1.3% – Cramer believes that Verizon is going from $30 to $35.

Cinemark Holdings (CNK: 20.07 0.00%) fell 0.1% – Cramer dislikes the cinema business due to their high debt loads.

CNH Global(CNH: 43.97 0.00%) gained 0.5% – Cramer was bearish and recommended selling the stock.

On Wednesday’s Mad Money show, Jim Cramer told investors that it’s not a question of whether or not to own gold, but how to own gold. Cramer believes that investors can capture some short-term gains by trading gold, as the metal seems to perform better in the second half of the year. Cramer recommended Agnico Eagle Mines (AEM: 35.50 0.00%) as his favorite way to play gold sending the stock up 6.9%. The company continues to expand its production and has seen a 9% increase in its stock price since the beginning of the year. AEM stands to benefit from the rising price of gold since they don’t engage in hedging. Cramer continues to be bullish on gold overall with the uncertainty in the economy and the declining value of global currency. 

Another stock getting a boost from the “Cramer effect” was XTO Energy (XTO: 0.00 N/A). The stock gained 3.4% after a bullish recommendation from Cramer in the Lightning Round segment of Wednesday’s Mad Money show. Cramer called XTO “the signle best performing natural gas stock in history/”. 

Potash (POT: 46.46 0.00%) jumped 3.0% after Cramer stated that fertilizer is one commodity that is immune to the influence of China. Potash is Cramer’s pick in the fertilizer space despite the falling demand seen in recent quarters. Cramer thinks orders will increase once again as the economy begins to recover and farmers see they can’t cut back on necessities like fertilizer for very long.

On Tuesday’s Mad Money show, Jim Cramer labeled First Niagara Financial Group (FNFG: 9.74 0.00%) as the next big “super regional” bank. He is excited about the company’s acquisition of Harleysville National and its expansion in Pennsylvania and New York.   The markets responded positively to the bullish comments, sending First Niagra’s stock up 4.3%.

In the Lightning Round segment of Tuesday’s Mad Money show, Mr. Cramer recommended Smith Micro Software (SMSI: 2.58 0.00%). Cramer likes the company as it operates within the mobile internet family. He recommended investors keep buying the stock. Evidently it was good advice, as the stock gained 6.4%. 

Mosaic (MOS: 56.23 0.00%) also was impacted by the “Cramer effect”, as the stock lost 3.2% in Wednesday’s trading session after bearish comments from Mr. Cramer. Cramer advised investors against investing in Mosaic. “Don’t go with Mosaic, which happens to be, I think, Mel Gibson’s favorite fertilizer play.” 

Meanwhile, United Health (UNH: 52.14 0.00%), Wellpoint (WLP: 64.83 0.00%) and Aetna (AET: 45.14 0.00%) all dropped despite Jim Cramer declaring President Obama’s healthcare bill “dead on arrival”. Cramer expects an upturn in the healthcare sector, but may have been a bit premature in his recommendation as all three stocks dropped big in Wednesday’s trading session. 

Other Cramer stock picks: 

Cypress Semiconductors (CY: 18.37 0.00%) gained 3.2% – Cramer likes the mobile internet sector.

RF Microdevices (RFMD: 5.33 0.00%) rose 2.4% – Part of Cramer’s recommendation of the mobile internet space.

Duoyan Global Water (DGW: 0.00 N/A) a Chinese stock that many had probably never heard of before Thursday night’s Mad Money show, gained a whopping 8.6% on Friday. In the Lightning Round segment Cramer stated, “It is a Chinese water company, the answer to a lot of people’s prayers is to try to find some play on water.” However, Cramer didn’t want to embrace DGW despite being a big believer in China. Nevertheless, the mere mention of the stock seemed to put it on the radar screen for many investors. 

Mylan (MYL: 22.89 0.00%) gain 3.3% despite the fact that Cramer said he preferred Teva Pharmaceuticals (TEVA: 44.94 0.00%) over Mylan. “You know, it has been a hot stock. If you are going to be in there, I like Teva Pharmaceutical Industries Ltd.” Teva’s stock finished virtually unchaged. 

Finally, Palm (PALM: 0.00 N/A) gained 2.2% on Friday even though Cramer recommended selling the stock and taking profits. A month ago Cramer was very bullish on Palm ahead of the release of the Pre phone, but with rumors of high return rates and low sales volumes Cramer would be selling the stock now. 

Other Cramer bullish stock picks: 

Google (GOOOG: 0.00 N/A) gained 2.1% – Cramer is bullish on tech stocks because these companies keep coming out with new products and don’t need any bailout money.

Aruba Networks (ARUN: 23.55 0.00%) rose 1.6% – “It is a buy, buy, buy… it is a little $7, $8 stock… I think that it goes higher.”

Apple (AAPL: 476.68 0.00%) jumped 1.4% – Cramer is clearly a strong fan of Apple and he believes it is the most “Washington-immune” tech stock and predicts the stock will reach $200.

Huntington Bancshares (HBAN: 6.05 0.00%) received the biggest boost from the “Cramer Effect” as its shares jumped 6.7%. In the Lightning Round of Friday’s Mad Money show, Jim Cramer had reiterated his earlier recommendation of HBAN from early June. “Why aren’t you in Huntington Bancshares?” 

Cramer’s other bullish stock pick, ArcSight (ARST: 0.00 N/A) also performed quite well with shares rising 5.7%. Cramer recommended investors look at ArcSight following on the recent cyberattacks in Korea and the United States. Cramer believes that cyber security will be the next big trend and thinks ArcSight stands out because of its clean balance sheet, decent growth rate, and $91 million in cash. Although ArcSight trades at a relatively high earnings multiple, Cramer would pay twice the company’s growth rate for the stock, and the fact that earnings estimates are so low may be an indication of an upside surprise. 

Other Cramer bullish picks: 

NetApp (NTAP: 39.775 0.00%) gained 4.3% – “Net App is a winner! I wanted them to get Data Domain, but now I don’t know how they stay independent. I think the quarter is better-than-expected.”

Sallie Mae (SLM: 15.76 0.00%) up 4.4% – “Now that the stock has pulled back, I want you to pull the trigger again. I think Sallie Mae is a winner.”

Apple (AAPL: 476.68 0.00%) jumped 4.4% – Cramer predicts Apple will report quarterly earnings that will “blow your socks off.”

Honeywell (AAPL: 476.68 0.00%) gained 3.8% – Cramer would be a buyer of Honeywell which is down 23 points, but has an impressive 4% dividend yield.
