NEW YORK ( TheStreet) -- There are exceptions to every rule, Jim Cramer told his "Mad Money" TV show viewers Wednesday. When it comes to the stock market, everything is most definitely not rational.

Cramer said the industrial stocks continue to soar despite having nothing new to say. Meanwhile, Johnson & Johnson ( JNJ) saw its shares barely dinged despite cutting estimates.

In the tech sector, investors continue to pile into stocks like ( AMZN - Get Report) and LinkedIn ( LNKD), two stocks that don't seem to be constrained by traditional metrics, said Cramer.

And then there's Apple ( AAPL - Get Report), a stock Cramer owns for his charitable trust, Action Alerts PLUS. Apple's in-line results were seen as a disappointment, said Cramer, sending its shares down 8% in after-hours trading.

Despite having $137 billion in cash and pretty good earnings, the markets were focused on gross margins, which came in below consensus at 38.6%. The number of iPhones sold was also a tad below what Wall Street was expecting. Are sellers just taking profits or are they worn down by the stocks' total lack of momentum?

Cramer said it doesn't matter what the reason, but investors need to remove the emotions from Apple and realize that it's just another stock, one that will likely deliver decent, but not spectacular, earnings from here on out. Apple has a ton of potential, he said, but under Tim Cook we have yet to see any blockbuster new products that don't cannibalize existing ones.

"Don't let this one stock blind you to the other opportunities the market is offering," Cramer concluded.

Know Your IPO

In the "Know Your IPO" segment, Cramer highlighted Zoetis, the animal health division of Pfizer ( PFE - Get Report), which is expected to offer 86.1 million shares next week between $22 and $25 a share.

Cramer said that Zoeits plays into the $22 billion animal health market, in which it currently has a 19% share. The new company makes everything from vaccines to feed additives and will derive 65% of its revenue from livestock and the remaining 35% from horses and household pets.

Cramer noted that unlike the human health-care market, most animal patient bills are paid out of pocket. When it comes to drugs and vaccines, there is far less generic competition. Given the stock's expected valuation and growth rate of 6%, Cramer said he expects Zoetis to have 20% upside from its IPO.

So should investors sell Pfizer to buy Zoetis? Cramer said absolutely not! Pfizer will retain 80% of Zoetis after the IPO and will be using the proceeds to reward shareholders with a sizable stock buyback. In addition, the split companies will both receive higher market valuations as individual companies are easier for analysts to value.

Cramer said he would get in on the Zoetis IPO if possible, but noted that existing Pfizer shareholders will also do quite well in 2013.

Riding the Rails

There's a bull market roaring on America's rails, Cramer told viewers, but that doesn't mean investors should jump into just any rail stock. He said while railroad operators CSX ( CSX - Get Report) and Norfolk Southern ( NSC - Get Report) have all posted terrific results, it's the rail car makers that represent the most value.

Specifically, the demand for tanker cars has been red-hot as the American energy renaissance has created the need for thousands of new tankers. Other industries need them, too, to move everything from chemicals to corn syrup.

The railroad business is highly cyclical, Cramer warned, which means that if the economy falters, this group will be hit hard. But if America continues to recover, then the rail car makers is the place to be.

Of the four major players, Cramer said that American Railcar ( ARII) is his favorite, as the company gets 20% of sales from tankers and it offers a 2.8% dividend. Next on the list would be Trinity Industries ( TRN - Get Report), which also gets 20% of revenue from tankers. Unlike American, Trinity has exposure to other industries such as barges and windmills, which makes it more risky.

Cramer said he'd avoid FreightCar America ( RAIL - Get Report) because that car maker has a lot of exposure to the weak coal market. He is also not a fan of Greenbriar ( GBX - Get Report).

Lightning Round

In the Lightning Round, Cramer was bullish on EOG Resources ( EOG - Get Report), Westar Energy ( WR), Morgan Stanley ( MS - Get Report), Duke Energy ( DUK - Get Report), Masco ( MAS - Get Report), Healthcare Trust of America ( HTA - Get Report) and Travelers Companies ( TRV - Get Report).

Cramer was bearish on Isis Pharmaceuticals ( ISIS), Nuance Communications ( NUAN - Get Report) and Genworth Financial ( GNW - Get Report).

Am I Diversified?

In the "Am I Diversified?" segment, Cramer spoke with callers and responded to tweets sent via Twitter to @JimCramer to see if investors' portfolios have what it takes for today's markets.

The first portfolio included: Armour Residential ( ARR - Get Report), LinnCo ( LNCO), Nordic American Tanker ( NAT - Get Report), Banco Santander ( SAN) and Vodaphone ( VOD).

Cramer said this portfolio was "perfection" when it comes to diversification.

The second portfolio's top holdings included: Ford ( F - Get Report), Dana Holding ( DAN - Get Report), Smith & Wesson ( SWHC), Alcoa ( AA - Get Report) and KeyCorp ( KEY - Get Report).

Cramer advised selling Dana and adding a drug company to properly diversify this portfolio.

The third portfolio had: Chicago Bridge & Iron ( CBI), Eaton ( ETN - Get Report), HollyFrontier ( HFC - Get Report), Penske Automotive ( PAG - Get Report) and Westport Innovations ( WPRT - Get Report) as its top five stocks.

Cramer said he'd allow Westport and Penske in the same portfolio assuming Westport is considered a speculative stock.

No Huddle Offense

In his "No Huddle Offense" segment, Cramer highlighted a handful of terrific earnings reports. He said that DuPont ( DD - Get Report), an Action Alerts PLUS holding, was like a "C" student delivering a solid "B" on the final exam. Meanwhile, Travelers delivered a fantastic quarter that no one saw coming.

Then there's IBM ( IBM - Get Report), another Action Alerts PLUS name. Cramer said this company continues to make a ton of money with 90% margins in software.

Finally, there's Google ( GOOG - Get Report), a company that blindsided investors last quarter, but redeemed itself this one with both earnings and a solid strategy for growth and profitability.
