Asset manager Brent Johnson of Santiago Capital is the man behind the “Dollar Milkshake Theory.” The name for this theory comes from the concept of extracting oil from a neighboring property by “drilling” a longer straw. Brent argues that the United States has this magic straw and regularly uses it to suck up the world’s capital. His theory’s controversial idea is that US equities are going to go to all-time highs along with a stronger US dollar at the expense of most foreign currencies.
