Which Stocks Wouldn't Get on the Royal Wedding Guest List?

If stocks could attend the wedding of Prince William and Kate Middleton on Friday, Cramer said four names wouldn't likely get an invitation.

BP is too controversial to be invited, Cramer said. One year has passed since the oil spill in the Gulf of Mexico, but Cramer said the company won't get back to pre-spill production levels until 2016. The "Mad Money" host recommends staying away from this oil giant until all spill-related lawsuits are resolved. In addition to issues regarding the spill, Cramer noted BP's costly joint venture with Russia-based Rosneft is being blocked by AAr, a competing firm that also operates in the country's stretch of the artic.

Stay away from BP shares and buy Royal Dutch Shell instead, Cramer said. He would wait until the company reports earnings on April 27 before buying shares, though.

Lloyd's is another company that Cramer doesn't thinks would be on the guest list. Cramer likened it to the Citigroup of Britain, only he said it's two years behind where Citi is now. Its numbers are being cut, margins are falling, the government is in control and the chart is awful, Cramer said. The European Union has mandated it must fire sale 600 of its 3,000 branches by November 2013, as well as a large part of its residential mortgage business.

Instead of investing in Lloyd's, Cramer suggests Royal Bank of Canada . RY, he said, is like the JPMorgan Chase of the Great White North.

BT Group is another company that should be kept from attending the wedding, Cramer said. Formerly known as British Telecom, this U.K.-based landline operator and Internet provider is like a low-yielding version of CenturyLink or Windstream , he explained. Cramer thinks it's a shrinking business with weak numbers, so stay away.

Finally, Cramer wouldn't consider shares of Diageo . The London-based liquor company makes a range of brands, including Johnnie Walker scotch whiskies, Smirnoff vodka, Baileys Original Irish Cream liqueur, Captain Morgan rum, Jose Cuervo tequila, JeB scotch whisky, Tanqueray gin and Guinness stout. Still, a weak U.S. dollar means the company's earnings in the U.S. will translate into fewer pounds in England. It's a good business, Cramer said, but there are currency issues right now.
