sideways market
n.— «The stock market has been sending a series of mixed signals recently—a few days of strong gains followed by a few days of discouraging declines. This is what Wall Street refers to as a “sideways market”—and it’s exactly what many analysts had predicted.» —“Prosperity may be just around corner” by Gene Walden Star Tribune (Minneapolis-St. Paul, Minnesota) May 10, 2008.
