After a whipsaw week in the markets that saw the Dow Jones industrial average travel more than 10,000 points in five trading sessions, investors are searching for clues that the selling may be over. According to one trader who relies heavily on the charts, once such sign could be found in the currency markets.
"Fast Money" trader Brian Kelly said that, in the past year, the S&P 500 Index has seen three declines of 5 percent. In each of those instances, a rally in the U.S. dollar marked the end of that selling.
"Each of those times, a day or two before the stock market bottoms, the U.S. dollar tends to bottom. The thesis behind this being a stronger dollar means a strong U.S. economy," said Kelly.
