Cramer's 'Mad Money' Recap: Bulk Up on Dry Bulk Shippers

Cramer concluded by stressing the value of the play. Because dry bulk shipping companies don't invest in growth (they rarely build new ships), they pay a lot of dividends back to investors.

Even though investing in these stocks is "not sexy," sometimes you have to go for the easy money, and that's what dry bulk shippers offer.

Cramer stressed that dry bulk shipping is a set of stocks that work in the same way that Deere (DE Quote), Foster Wheeler (FWLT Quote) and Schlumberger (SLB Quote) fo. These companies are consistent performers that pay big dividends.

Globalization and high demand for raw materials in China are behind bulk shippers' recent success, Cramer said. In addition, because dry bulk ships offer lower margins for shipbuilders, few of them are being made, so the ships are scarce. The high demand and short supply work together to drive up the price of this kind of shipping, Cramer said.

All of these companies are in the "sweet spot," Cramer said, but they can be grouped into two distinct groups that offer different scenarios to investors. The first group of shippers is completely chartered out for the year, meaning that changes in the Baltic Exchange Dry Index, an indicator of the price of dry bulk shipping, will not affect the stocks' performance. Those companies have already booked their shipping in advance, so they offer steadier performance that doesn't depend on external factors, Cramer said. Conservative investors should opt for these companies.
