The Russell 2000 has lost roughly 18% of its value peak to trough, and that is not good news for the US economy.
During the past twenty years, coincident and lagged values of the index have been a reasonably good predictor of GDP. In the regression below I use a polynomial distributed lag of quarterly changes in RTY vs quarterly changes in real GDP (coincident and four quarterly lags).
RTY gives somewhat better results than the S&P 500. This is far from perfect but close enough to merit attention.
