The Arms Index, a volume-weighted measure of market breadth, suggests that despite the stock market's broad and sharp declines on Thursday, the unwind appears to be orderly. The so-called Arms Index tends to rise above 1.000 when the broad market declines, as the ratio of volume in declining stocks over advancers tends to rise relative to the ratio of the number of declining stocks to advancers, as sellers become more aggressive than buyers. A reading of 2.000 or higher is viewed by many as signaling panic. However, the NYSE Arms was at just 0.904 and the Nasdaq Arms was at 0.632, although the Dow Jones Industrial Average [: DJIA] tumbled more than 400 points, or 1.6%, at 25,357, and the Nasdaq Composite Index shed 2% at 7,602. The S&P 500 index was off 1.6% at 2,810, late afternoon Thursday. Currently, declining stocks were 2,320 versus 484 advancers on the NYSE, roughly the same ratio on the Nasdaq. Moves for stocks came as the benchmark 10-year Treasury note yielded 2.30%, falling to its lowest level since December of 2017. Heightened fear of trade war, which could disrupt economic growth was at the heart of the selloff. The relatively placid selling, however, could, perhaps, be pegged to a Memorial Day holiday, with markets in the U.S. set to be closed.
