The cemetery can be a spooky place, Jim Cramer warned his Mad Money viewers Monday. That's why it's starting to get a little worrisome that investors are whistling past some serious graveyards on the way to new market highs.

Make no mistake, Donald Trump's promises of lower taxes, less regulation and the repatriation of overseas funds would be great for American business, Cramer said, but there are also some big negatives looming on the horizon.

The first negative is the sharp rise in oil prices, which is not being caused by growing demand, but rather by OPEC manipulation. Then there's China, where sharpening rhetoric on both sides is beginning to raise lots of questions.

Trump's cabinet picks, while generally pro-business, are also beginning to worry money managers who are not accustomed to so many changes all at once. So too is Trump's growing list of attacks on individual CEOs.

Then there is the issue of rising interest rates, which have been spiking, along with mortgage rates. Will the Federal Reserve need to raise rates even faster to keep up?

Add up all of these concerns and it's easy to see why money managers are starting to get spooked by the growing list of unknowns.

Regional Banks Gain Despite Downgrades

It's no surprise that the banks have been leading the markets higher since the election. But what is a surprise is that the regional banks in particular have been doing so while getting pummeled with analyst downgrades.

Cramer's been a longtime fan of BB&T(BBT) - Get Report , a stock that received no less than five downgrades ahead of the election, and another two downgrades since. According to the analysts, the bank has run out of catalysts to propel it higher. Shares of BB&T are up over 10% since the election.

Likewise with Fifth Third Bank(FITB) - Get Report , a stellar regional bank with six downgrades ahead of the election and three since. Shares are up 20% since November.

The list goes on, Cramer said, with Key Corp(KEY) - Get Report , Regions Financial(RF) - Get Report and SunTrust Banks(STI) - Get Report all seeing multiple undeserved and short-sighted downgrades.

Despite the lack of support from Wall Street, all of these stocks have been soaring, Cramer concluded, and that's how you know the rally is for real.

Broadcom Deal Looks Great

What's not to like about Broadcom(AVGO) - Get Report , the chip maker with shares up over 30% so far this year? Cramer said the company's merger with Avago for $37 billion is one of the best deals he's ever seen, yet it remains under-appreciated by Wall Street.

After closing on the Avago deal, the new Broadcom is now the third largest semiconductor company in the world, and even after posting strong results that sent shares up 5%, Cramer said, the stock still has a lot more upside.

Broadcom has successfully diversified itself away from just smart-phone chips and now boasts wired and wireless communications chips, along with chips for the data center, hard drives and, yes, the red-hot Internet of things. The company just posted a 9% increase in revenue and doubled its dividend yield to 2.3%.

Cramer last recommended Broadcom in April at $157 a share, or 12.3 times earnings. He likes it even more now at $178 a share, because earnings estimates are up, keeping the price earning ratio below 13.

Shares of Avago, now Broadcom, are up over 1,000% since their August 2009 IPO and Cramer said he's still a believer in the company's management.

Executive Decision: DCT Industrial

For his "Executive Decision" segment, Cramer sat down with Phil Hawkins, president and CEO of DCT Industrial Trust (DCT) , an industrial and warehouse REIT with a 25% return so far this year.

Hawkins said that investors shouldn't fret over short-term interest rates but instead look at his company's underlying businesses. A faster growing economy, he said, is good for business and he's looking forward to seeing the U.S. move at a healthier pace.

When asked about his business at a micro level, Hawkins said that demand has been robust in all sectors, not just in e-commerce, where tenants like Amazon.com(AMZN) - Get Report and FedEx(FDX) - Get Report are seeing increased demand.

DCT's strategy is to build properties near urban centers that are difficult to replicate and therefore add value. In many cases, the company builds or modifies a property to suit specific needs of their tenants, he said.

Lightning Round

In the Lightning Round, Cramer was bullish on Gilead Sciences(GILD) - Get Report , PolyOne(POL) - Get Report , Dow Chemical(DOW) - Get Report , General Electric(GE) - Get Report , CyberArk Software(CYBR) - Get Report , AGCO(AGCO) - Get Report , MGM Resorts(MGM) - Get Report , Smith & Wesson (SWHC) and General Motors(GM) - Get Report .

Cramer was bearish on Banc of California(BANC) - Get Report , McDermott International(MDR) - Get Report , Potash (POT) , Wynn Resorts(WYNN) - Get Report , Transocean(RIG) - Get Report and Ford Motor(F) - Get Report .

No-Huddle Offense

In his "No-Huddle Offense" segment, Cramer told investors not to be fooled: Our president-elect is indeed a shrewd negotiator.

Cramer said Trump's latest "tweet heard 'round the world" came at the expense of Lockheed Martin(LMT) - Get Report and the company's over-budget F-35 fighter jet. This after Trump took aim at United Technologies(UTX) - Get Report , Boeing(BA) - Get Report , Ford(F) - Get Report and the drug companies.

After all of these events, Cramer said, investors need to consider the risks of any company that sells to the government, is planning a big merger or has plans to move its operations overseas. He did not advocate selling all of these stocks, but told viewers that for now, they should be aware of the increased risks.
