Investors who have made money in stocks recently should consider drafting a thank you note to Fed chair Janet Yellen, according to trader Boris Schlossberg. After all, her policies have weakened the dollar and consequently paved the way for stocks to rise, he said.
"What's interesting is that the dollar has weakened over the last two quarters, and stocks have rallied," the BK Asset Management strategist said Thursday on CNBC's "Power Lunch." "I don't think that's a coincidence."
Schlossberg said that by not raising rates, the Fed is consciously allowing the dollar to weaken, thus giving a competitive advantage to U.S. exporters who benefit from a weaker greenback, in turn strengthening U.S. equities.
The U.S. dollar index has fallen 4 percent this year, while stocks have rallied 4 percent.
"The reason why all of this is happening," Schlossberg said, "is because they really want to make sure that we do not tip over into any kind of a global financial panic."
The correlation between the U.S. dollar and the S&P 500 tends to be positive — likely because both should tend to rise as the American economic outlook improves. Yet since the start of 2016, the correlation has fallen off a cliff, a CNBC analysis of FactSet data shows.
