Cramer receives a lot of questions from investors asking him what kind of homework he does when he picks stocks for CNBC's "Mad Money." So, to give investors the upper hand in how to properly assess a company, he decided to give a concrete example by examining Wednesday's quarter from Alcoa.
Cramer likes Alcoa because he believes in its long-term story, which is to transform itself away from being a commodity play on aluminum and into a producer of value-added materials.
He has always studied Alcoa closely by looking at the quarterly report, listening to its conference call and rewatching interviews with CEO Klaus Kleinfeld. He uses this information to spark new ideas about the macro picture of the economy, because many companies benefit from the trends that Alcoa highlights.
"My first takeaway, overall? The U.S. economy is doing better than expected. Kleinfeld hammered that home in every venue, and I believe it," the "Mad Money" host said.
How the heck did Cramer get all of that from Alcoa's fundamentals?
Because Alcoa breaks its business into many different end markets, and those businesses pretty much touch everything that is related to non-retail commerce. So it will provide a take on everything from aerospace, automotive, heavy duty truck and trailer, packaging, building and construction and industrial turbines—basically anything that requires metal.
"I'm not saying just go buy the stocks the homework leads you to. I am saying that Alcoa's quarter is a fantastic place to start the homework you need, or to verify thoughts you may already have on various investments," Cramer added.

And while Cramer is on a mission to help investors make money on the stock market, sometimes that means going off the tape to look at privately held companies that are on the cutting edge of trends disrupting the industry. That is why he spoke with Casper, a company that has disrupted the mattress industry, which hasn't had strong innovation in decades.
The idea is that clients can go on to Casper's website and order a mattress without having to deal with salespeople. And if you don't like it, then Casper will come and pick it up from you. The concept is to make the process of buying a mattress simple and convenient.
With investors such as Leonardo Dicaprio, Adam Levine and Tobey Maguire—could this be the mattress company with a dream team? To find out, Cramer spoke with Casper's co-founder and CEO, Philip Krim.
"It's funny, everyone relates to how terrible buying a mattress is. Our customers, investors all understand the opportunity to change the game when it comes to that. When you combine a great product with an unbelievable customer experience, everyone just seizes the opportunity, celebrity or not.
In the Lightning Round, Cramer gave his take on a few caller favorite stocks:
Boeing: "We are going to wait for the quarter, because sometimes it acts squishy in the quarter and then after it does that we will probably pull the trigger."
Dillard's: "A couple of downgrades and the stock is now down 40 straight points. I agree with you, I think it is overdone on the down side."
