Advisors like energy-related master limited partnerships not only for their solid dividend yields—often 6% or more—but because they are relatively stable investments and good for diversification.
MLPs are publicly traded limited partnerships. Because of their organizational structure, they don't pay corporate taxes and can pass much of their profits on to their investors. The safest bet is to stick with energy MLPs that own and operate oil and natural-gas pipelines, such as Kinder Morgan Energy Partners (KMP), yielding 6%, and Mark West Energy Partners (MWE), yielding 5.3%. These partnerships aren't closely correlated to stocks and aren't affected by the rise and fall in energy prices, because they collect fees for transporting oil and gas, no matter what happens to the prices.
