Sector early indicator? Retail sector - not much (but watch WMT)

The general Retail Sector (as opposed to retailing of hardware home improvements by Home Depot and Lowes - studied in an earlier chart) - here represented by the VanEck Vectors Retail ETF (RTH, in green), and the mighty Walmart (WMT, in blue) - only occasionally (more often by WMT) acts as an early indicator against the broader market (here represented by the DJIA in gray, and the NASDAQ in black)... falling from peaks... WMT peaking on 29 Dec 1999, WMT falling from a peak in Jun 2007, WMT fading from a peak in Jan 2011, WMT in Jan 2015, WMT in Dec 2019.
