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

Westport Innovations (WPRT: 40.27 +0.73%)
Westport Innovations shares soared 8.6% fueled by the “Cramer Effect”. Cramer advised investors that the best way to play natural gas is to invest in a company that is developing technologies to utilize natural gas. Westport Innovations fits that bill and Cramer feels the company has tremendous potential given their low market penetration. Currently, only 15% of WPRT’s sales come from North America. Increasing adoption of natural gas in the U.S. could push this stock much higher. “The underlying long-term story here could be incredible,” said Cramer.

Baker Hughes (BHI: 49.91 -2.19%)
Baker Hughes jumped 5.9% after Cramer warned that the global economic recovery would lead to increased oil consumption. This will lead to much higher oil prices and potentially even gas shortages. Obviously this would be great news of Baker Hughes as well as other major oil companies such as Marathon Oil (MRO: 32.69 -1.42%), Chevron (CVX: 106.76 -0.07%) and Weatherford International (WFT: 17.90 +0.62%).

Boeing (BA: 75.46 +0.94%)
Shares in Boeing gained 3.3% on Tuesday after Cramer remarked that “2010 will be the year for Boeing”.

Cramer’s Lightning Round stock picks:

• Akamai Technologies (AKAM: 34.44 +2.35%) gained 3.0% – Cramer called Akamai a “high quality play on the internet tsunami.”

• Citigroup (C: 34.23 +3.51%) jumped 3.8% – While not without risk, Cramer likes the stock and told investors that Citi is a “speculative situation that we like very much.”

• Apple (AAPL: 476.68 +1.67%) inched up 0.2% – Cramer remains Apple’s biggest fan and told investors that he stands by his $300 price target and believes AAPL could go even higher.

International Paper (IP: 30.95 -0.51%)
International Paper continues its recent rally, gaining another 2.1% after Jim Cramer called the company a “turnaround story” during his interview with CEO Jim Faraci. With the economic environment improving, Mr. Cramer feels that IP’s earnings could “explode” as shipping volumes increase once again. The company is benefitting from cost cutting initiatives and Cramer recommends the stock.

3Com (COMS: 0.00 N/A)
3Com jumped 6.5% after receiving a strong bullish endorsement from Jim Cramer on Friday. The company recently reported a strong quarter which seemed to have gone largely unnoticed. 3COM generates 40% of its sales from China and continues to take market share. Cramer likes 3COM’s pristine balance sheet and attractive valuation and recommends investors buy now.

Cramer’s Lightning Round stock picks:

Inverness Medical Innovations (IMA: 0.00 N/A) gained 2.6% – “I wish that I had not sold it… that is the highest compliment that I can pay.”
Westport Innovations (WPRT: 40.27 +0.73%) jumped 7.2% – Cramer likes the stock and likes Fuel System Solutions (FSYS: 24.10 +1.90%) even better.
Visa (V: 108.35 +1.28%) rose 0.7% – Cramer says to “buy, buy, buy” this stock.
McDonalds (MCD: 100.05 -0.85%) gained 0.4% – Cramer believes this is a stock that doesn’t get the respect it deserves and recommends that investors buy.

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

A123 Systems (AONE: 2.47 +8.10%)
A123 Systems, the hot IPO, dropped 3.4% after Cramer recommended that investors take their gains off the table. The battery maker went public yesterday at an offer price of $13.50. The stock shot to over $21 on its first day of trading.

Research in Motion (RIMM: 16.49 -1.32%)
Research in Motion fell big time today after posting disappointing revenue numbers yesterday. Jim Cramer appeared to have been lukewarm at best on RIMM over the last couple of months and has clearly preferred Apple (AAPL: 476.68 +1.67%). Last night, he once again urged investors to use the drop Research in Motion as an opportunity to buy Apple stock.

Cramer’s Lightning Round stock picks:

Clearwire Communications (CLWR: 1.95 +2.63%) fell 3.2% – Cramer was bearish on Clearwire and believes that investors have much better options in AT&T (T: 30.02 -0.07%) and Apple.
Live Nation (LYV: 10.64 +0.19%) dropped 1.8% – Cramer recommended investors take profits as he doesn’t see this stock going much higher.
Sallie Mae (SLM: 15.76 -0.38%) fell 1.0% – Cramer actually likes Sallie Mae which he believes will go to $10 by the end of the year.
Oracle (ORCL: 28.73 -0.76%) dropped 1.5% – “Oracle is flat lining here.”

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

Advanced Micro Devices (AMD: 7.25 +1.68%)
AMD shares fell 6.0% today after Cramer recommended investors take profits after the stock’s recent run up. While Mr. Cramer has been bullish on AMD in the past, the stock has nearly tripled since he recommended it and he accurately predicted a pullback in the stock.

Mobile Internet Tsunami
Cramer also seemed to offer an accurate prognostication of the pullback in the leading mobile internet stocks. Mr. Cramer said that investors should expect another 3 – 5% pullback. Today, Apple (AAPL: 476.68 +1.67%) only fell slightly, but Palm (PALM: 0.00 N/A) fell nearly 5% and Research in Motion (RIMM: 16.49 -1.32%) dropped 3% before falling another 11% in after-hours trading.

Cramer did emphasize that investors should recognize this pullback as a great buying opportunity. He continues to be a strong believer in the mobile internet tsunami and believes we are still early in the trend.

Cramer’s Lightning Round stock picks:

Huntsman (HUN: 13.59 +0.59%) fell 2.0% – Cramer was bearish on the stock and believes the rally is over.
Spectra Energy (SE: 31.01 -0.10%) dropped 1.2% – Cramer was positive on this stock due to their high 5.1% dividend yield.
Dana Holdings (DAN: 15.51 -1.34%) fell 3.1% – Cramer warned investors not to buy until the stock pulls back further.
Philip Morris International (PM: 77.88 +0.36%) dropped 1.1% – Cramer believes investors have already missed the move in this stock and is now bearish on PM.

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

Hain Celestial (HAIN: 40.90 -1.11%)
The Hain Celestial Group saw their stock jump 6.6% on Monday after Jim Cramer suggested that Kraft Foods forget their pursuit of Cadbury and take a look at Hain as a potential takeover target. Cramer is bullish on the trending popularity of healthy food choices. Hain Celestial products clearly fall in this sweet spot, with many of their products sold in popular stores like Whole Foods and Walmart. Meanwhile, Cadbury products will continue to be flagged as unhealthy options. Regardless, Cramer believes that Hain will likely be acquired either by Kraft or by some other suitor. When that happens, Cramer believes the stock will see an 85% takeover premium.

Tekelec (TKLC: 0.00 N/A)
Shares of Tekelec surged 6.1% after Cramer focused the spotlight on the telecom stock. Mr. Cramer has been the leading cheerleader for mobile internet companies and even created his own Mobile Internet Stock index in early August. Since that time the index has climbed over 13%, but investors seemed to have overlooked Tekelec. However, Cramer believes that investors are overlooking a great opportunity as TKLC trades at only 12 times earnings. Cramer believes the stock could gain another 68% and recommends investors consider this speculative stock.

Cramer’s Lightning Round stock picks:

Ebay (EBAY: 33.05 +0.55%) fell 0.7% – Cramer is bullish on the stock and expects it to go to $30.
Trinity Industries (TRN: 33.48 +1.95%) dropped 6.4% – Despite the poor performance last year, Cramer likes Trinity.
Caterpillar (CAT: 114.04 +0.20%) fell 1.8% – Cramer still recommends owning CAT.
Manitowoc (MTW: 16.38 +3.41%) dropped 2.2% – Cramer clearly dislikes the stock.

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

Baker Hughes (BHI: 49.91 -2.19%)
Baker Hughes’s stock soared 7.9% after Jim Cramer commented yesterday that he is bullish on the deal with BJ Services (BJS: 0.00 N/A). Cramer said that he has always liked Baker Hughes and “saluted” the company.

Yahoo (YHOO: 15.78 -0.32%)
Shares of Yahoo fell 0.6% despite bullish comments from Jim Cramer yesterday. Mr. Cramer said that Yahoo CEO Carol Bartz is being unfairly slammed and he thinks she’s doing a good job and deserves more time. He also believes that Yahoo is so far behind right now that the company is struggling to play catch-up. Cramer believes that Yahoo’s stock will rally to $21 which would provided investors with a 20% gain.

Cramer’s Lightning Round stock picks:

B&G Foods (BGS: 22.84 +1.51%) spiked 3.1% – Cramer sees this as a stable business that offers an incredibly high 8.5% dividend yield.
Terra Nitrogen (TNH: 210.50 +4.31%) jumped 2.0% – Another high yield stock that Cramer recommends for their 8.2% dividend yield.
STEC (STEC: 10.33 -2.46%) fell 4.6% – Continued its sell-off following yesterday’s price cut from Wedbush Morgan, but Cramer is bullish on the stock and recommends buying.
Las Vegas Sands (LVS: 52.07 +1.98%) dropped 0.7% – Cramer warned investors that this is a very speculative play and he is bearish on the stock following their recent rally.

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

Apple (AAPL: 476.68 +1.67%)
Apple’s stock soared 3.8% after Jim Cramer announced yesterday that he is increasing his price target from $200 to $264. Cramer believes that Wall Street’s earnings estimates are too low for Apple and believes the consensus estimates could climb from $8 to $12 per share. This will largely be the result of the expected changed in FASB regulations on how Apple can recognize revenue. Currently, revenue from new iPhone subscribers is spread over the 24 month contract period instead of being recognized up front. While Cramer believes that this could cause earnings estimates to increase dramatically, he believes the stock will maintain its current earnings multiple. That would drive Apple’s stock price considerably higher and he urged investors to get in now ahead of the announcement.

Flextronics (FLEX: 6.94 -0.43%)
Flextronics stock jumped 7.8% today after Technical Analyst Dan Fitzpatrick showed that the stock had already crossed its 50 day moving average and was ready for a breakout. Mr. Cramer likes the company for its fundamentals and diverse geographic exposure. Cramer believes that Flextronics is the cheapest stock in its sector and trades at only 12 times 2011 earnings estimates. While the stock has surged over 250% off its market lows, Cramer believes there is still more upside ahead.

Cramer’s Lightning Round stock picks:

First Solar (FSLR: 45.81 -1.67%) spiked 4.9% – Cramer continues to recommend First Solar as the only solar stock to buy.

Priceline (PCLN: 538.37 +1.73%) jumped 3.2% – Cramer called Priceline the Amazon.com of travel and believes the company has a strong business model and that the stock is only going higher.

Canadian Solar (CSIQ: 4.12 +11.05%) rose 5.0% – Despite bearish comments by Cramer who stated that he was nervous about solar stocks in general.

Movado (MOV: 18.99 +1.23%) jumped 2.8% – Another stock that Cramer was bearish on due to its position within the high-end market.

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

Gold Stocks
Yamana Gold (AUY: 16.62 -1.25%), El Dorado Gold (EGO: 14.06 -2.97%), Agnic-Eagle Mines (AEM: 35.50 -1.77%) and SPDR Gold Shares (GLD: 168.50 -0.71%) also posted impressive gains today after Jim Cramer announced that gold stocks were cheap on the Lightning Round segment of yesterday’s Mad Money show. His favorite gold play remains the SPDR Gold Shares ETF.

Airgas (ARG: 79.73 +1.12%)
Airgas stock jumped 2.6% today after Cramer interviewed CEO Peter McCausland on yesterday’s Mad Money program. Mr. McCausland reported that demand from infrastructure builders is beginning to return. The company is seeing increased demand for its industrial gases. Cramer announced that he liked the management team at Airgas and recommended that investors buy this stock.

Tenet Healthcare (TNH: 210.50 +4.31%) rose 0.6% – “I think the hospitals are in the sweet spot they are the winners under Obama. They are a protected class.”

Research in Motion (RIMM: 16.49 -1.32%) jumped 2.1% – Cramer claimed that RIMM has “got the Mojo” and believes the stock will be a winner.

Apple (AAPL: 476.68 +1.67%) inched 0.8% higher – Even at their current 52-week high, Cramer is still a big fan of Apple and thinks there even better than Research in Motion.

Whirlpool (WHR: 70.20 -0.71%) climbed 2.1% – Cramer likes the company’s booming business in Brazil and believes the stock will go even higher.

Dominion Resources (D: 50.20 -0.44%) up 0.8% – Another high yielding (5.3%) dividend stock that Cramer likes and he believes their dividend will remain safe.

Sinovac Biotech (SVA: 2.17 +0.46%) jumped 4.5% – While Cramer usually stays away from Chinese stocks, he was very bullish on this stock.

Emdeon (EM: 0.00 N/A) rose 1.6% – Cramer recommends investors buy this stock and believes it will hit $18.50.

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

Healthcare Reform Stocks
MedcoHealth Solutions (MHS: 60.82 +0.33%), Express Scripts (ESRX: 50.78 -0.42%), St Jude Medical (STJ: 43.51 +0.21%) and Boston Scientific (BSX: 5.95 0.00%) also posted nice gains today after Jim Cramer predicted that President Obama’s healthcare reform plan was unlikely to go through. Cramer was bullish on these healthcare stocks and urged investors to buy given the unlikelihood of Obama’s reform program getting through Congress.

Skyworks Solutions (SWKS: 24.28 +2.49%)
Skyworks Solutions stock jumped 12% today after Cramer interviewed CEO David Aldrich on yesterday’s Mad Money program. Cramer has been very bullish on the mobile internet revolution and included the stock in his Mobile Internet Index that he created on August 11.

The Skyworks CEO believes the company’s outlook is improving due to increasing consumer demand. The company is also benefitting from the increasing adoption of Wifi technology. Cramer reiterated his strong bullish views on Skyworks and the mobile internet sector in general.

Cramer’s Lightning Round stock picks:

XTO Energy (XTO: 0.00 N/A) jumped 3.9% – Cramer recommended that investors stick with the stock for the second consecutive day.
Brigham Exploration (BEXP: 0.00 N/A) fell 0.3% – Cramer was bearish on the stock and believes its run is over.

Anadarko Petroleum (APA: 105.11 +0.55%)
Jim Cramer interviewed Anadarko Petroleum’s CEO Jim Hackett on yesterday’s Mad Money show. Mr. Cramer has been very bullish on the prospect of natural gas being a bridge fuel from oil to wind or solar energy. Cramer feels that APA is one of the best natural gas stocks and believes that natural gas stocks could double. Despite the bullish endorsement, Anadarko’s stock slid 2.4%.

Fannie Mae (FNM: 0.00 N/A)
Another stock that seemed to buck the “Cramer effect” was Fannie Mae. Cramer said investors were foolish to speculate on Fannie Mae and Freddie Mac (FRE: 0.00 N/A) given their uncertain future. However, investors seem to shrug off the warning that these shares could eventually be worthless and Fannie Mae’s stock shot up 9.4%.

Banco Bilbao (BBV: 0.00 N/A)
Banco Bilbao, the Argentina bank stock, rose 5.4% on Tuesday after Cramer said he preferred the stock over Banco Santander (STD: 8.75 +1.86%).

TJX Companies (TJX: 34.42 -0.52%)
TJX rose 3.6% after Cramer featured the stock in his weeklong special feature on discount retailers. While Cramer likes TJX’s clean balance sheet and growth, he believes the stock has little upside left. The company is no longer benefitting from retailers dumping inventory at fire sale prices and is currently having trouble with their Marshalls and Homegoods stores. Cramer thinks TJX has seen better days and is bearish on the stock. However, bullish investors seem to have ignored his warnings.

Other Cramer stock picks:

First Solar (FSLR: 45.81 -1.67%) rose 3.3% – Cramer is bullish on solar stocks even though they are out of fashion right now.
Citigroup [[C] gained 1.1% – Again investors didn’t seem to heed Cramer’s warning that the stock has already gone up too much too fast.
