Now, however, the recent market correction has created an exceptional long-term high-yield opportunity you won't want to miss. So let me share three reasons I believe Brookfield Infrastructure Partners (NYSE: BIP) is by far America's best utility stock and deserving of a spot in your diversified dividend portfolio. World-class diversification and unsurpassed cash flow stability I've never seenany utility with such vast geographic and industry diversification as Brookfield Infrastructure Partners. It owns some incredible deep-moat assets all over the world, such as: 10,800 km of electrical transmission lines, 2.4 million electricity and gas connections, and 9,900 km of railroads on four continents -- among many others.
