NEW YORK (

TheStreet

) -- "Earnings matter," were Jim Cramer's words of wisdom to the viewers of his

"Mad Money"

TV show Friday, as he told investors to not be blinded by macroeconomic news, and instead focus on the stocks that are doing exceptionally well.

Cramer said the strength in U.S. markets today was due to earnings finally being too good to ignore. He said while the rest of the world sold off on China's half point interest rate hike, U.S. stocks were on a tear based on good old fashioned earnings and takeover speculation.

So what's in store for next week's game plan? Cramer said he'll be watching

Hewlett Packard

(HPQ) - Get Report

on Monday for a read on the tech sector. Will HP be another

Cisco

(CSCO) - Get Report

, a stock which Cramer owns for his charitable trust,

Action Alerts PLUS, or another

Salesforce.com

(CRM) - Get Report

?

On Tuesday, Cramer's attention turns toward

J.Crew

( JCG), a retailer in no man's land since it reported a bleak outlook last quarter. Cramer said he'd be a buyer if the stock goes lower, as 2011 should be a great year for the company.

Cramer said he'll also be watching

Cracker Barrel

(CBRL) - Get Report

on Tuesday, hoping it goes lower so investors can get in at a better price. He'll also have an eye on

John Deere

(DE) - Get Report

on Wednesday, as that stock will likely go lower on the company's historically downbeat conference calls.

Finally, Cramer said the Federal Reserve minutes to be released on Wednesday will pressure stocks. He told investors to keep their shopping lists ready to pounce on any bargains.

An Environmental Cleanup Leader

In the "Executive Decision" segment, Cramer spoke with Alan McKim, chairman, president and CEO of

Clean Harbors

(CLH) - Get Report

, one of the leaders in the environmental cleanup business. Clean Harbors recently reported a 36 cent a share earnings beat on year over year revenues that were up 90%.

McKim said the economy is picking up, and Clean Harbors is seeing waste volume at their incinerators and landfills picking up. He said the chemical and refining business is especially strong, and the company is getting calls for environmental cleanup projects every day.

McKim also said that Clean Harbors is in a good position, as there haven't been any new incinerators built in the last 15 years. At the company's landfills, he said pricing is looking good and will be improving in 2011.

McKim said he's excited about opportunities in the pharmaceutical industry as well as in natural gas drilling, where every rig needs Clean Harbor services to handle their waste operations. He said that Clean Harbors already has many contracts in place, and can respond in just hours wherever they are needed.

Cramer reiterated his buy recommendation on Clean Harbors, saying the stock is still way too cheap, and he'd be a buyer on Monday.

Energy Efficiency Play

For "Speculation Friday," Cramer showed investors how to effectively speculate on the growing energy efficiency trend. He once again recommended

Ameresco

(AMRC) - Get Report

, a stock he recommended when it IPO'd on July 20.

Back in July, Cramer said he liked Ameresco's consulting, engineering and implementation business that centered around making buildings more energy efficient. He said Ameresco's stock would act like a tortoise, and slowly crawl its way higher. Since then, shares have indeed slowly risen, up 23%.

Months later, Cramer said Ameresco is still a buy. He said the company's services are still in huge demand, with Ameresco's backlog approaching $1 billion, despite its $500 million marketcap. Ameresco's services help customers achieve a 40% return on their efficiency investment, often recouping that investment in less than two years.

Cramer said other than great earnings visibility, he also likes that Ameresco is not beholden to any one client. He called the company a smart speculation in a smart business, and he'd continue to be a buyer at these levels.

Green Week Wraps Up

Closing out his "Green Week" theme, Cramer recommended not one, but two, filtration stocks that help companies save energy by keeping their equipment running smoothly.

Cramer said

Pall Corp

(PLL) - Get Report

is an excellent choice, as the company makes filters for everything from biotech to water, aerospace to food and beverage and beyond. Cramer said Pall Corp has a stable, but growing, business with nearly three quarters of the company's revenues coming from recurring filter replacements.

Cramer said he also likes

Donaldson

(DCI) - Get Report

, a primarily industrial filter maker that recently beat earnings and raised guidance. Donaldson projects the $8 billion industrial filter market could rise to $11 billion by 2016. Cramer said trading at just 18 times earnings with a 12% growth rate, Donaldson's stock is just way too cheap.

Lightning Round

In the Lightning Round, Cramer was bullish on

Annaly Capital

(NLY) - Get Report

,

Chevron

(CVX) - Get Report

,

Bank of America

(BAC) - Get Report

,

Oracle

(ORCL) - Get Report

,

Salesforce.com

(CRM) - Get Report

and

F5 Networks

(FFIV) - Get Report

.

Cramer was bearish on

American Capital Agency

(AGNC) - Get Report

,

Aegean Marine Petroleum Network

(ANW)

,

Dryships

(DRYS) - Get Report

and

Nordic American Tanker

(NAT) - Get Report

.

Closing Comments

In his closing comments, Cramer said those criticizing the recent

General Motors

(GM) - Get Report

IPO are just nuts.

Cramer said imagine the heat the government would have taken if the deal had been priced too low, leaving money on the table. And think of the criticism if the deal would have been priced too high, and investors lost money on the first day.

But instead, Cramer said the IPO was near perfect, a gigantic deal that was placed, and priced, just right.

Cramer said he still wishes that the government would have made the IPO more accessible to the individual investor, perhaps with an auction format, but given how the deal came about, he said we couldn't ask for more.
