The make of smartphone power amplifiers recently reported strong quarterly results that exceeded Wall Street’s consensus estimates by $.02. The company also increased their guidance numbers, but the stock price continues to fall.

In an interview with Mr. Cramer, Skyworks CEO David Aldrich opined that we are still in the early stages of mobile internet adoption. He believes that Skyworks is delivering better margins than most of their competitors and sees tremendous growth opportunities ahead for leveraging the technology developed for smartphones.

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

Security Stocks
American Science & Engineering (ASEI: 68.84 -1.12%) stock soared 5.8% after Cramer discussed Homeland Security as one of his key investing themes for 2010. ASEI manufactures X-ray equipment for the U.S. government. Cramer sees tremendous potential in ASEI’s products and believes the company has the opportunity to grow their current revenue levels by 10x.

Cramer also highlighted OSI Systems (OSIS: 54.72 +0.51%) as another potential play on Homeland Security. OSIS’s shares closed up 2.6%.

Ford Motor (F: 12.84 -0.31%)
Ford’s stock jumped 3.7% following yesterday’s report that vehicle sales increase 33% in December. While General Motors remained the leader in overall vehicle sales, Cramer warned GM that they had better watch out for Ford which is quickly closing the gap.

Nice Systems (NICE: 35.21 -0.59%)
Shares in Israeli security firm Nice Systems gained 4.5% after Jim Cramer advised investors that the stock represented a great buying opportunity. At its current valuation multiple of only 18x earnings, Cramer believes the stock is a great value.

Cramer’s Lightning Round stock picks:

• Microsoft(MSFT: 30.66 +1.02%) dropped 0.6% – Despite Cramer offering a $35 price target on the stock that currently trades for less than $31.

• Pepsico [[PEP] fell 1.0% – Despite Cramer advising investors to buy the stock “aggressively”.

• Dow Chemical (DOW: 33.95 +0.27%) rose 1.8% – While Cramer believes they overpaid to acquire Rohm & Haas, he believes the company deserves credit for their execution since.

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”.

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.”

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.

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:

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.

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.

Ebay (EBAY: 33.05 +0.55%) fell 0.7% – Cramer is bullish on the stock and expects it to go to $30.

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.

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.
