The Nasdaq Composite (.IXIC) closed Monday at its lowest level in more than two months. With this, the Nasdaq McClellan Summation (McSum), a breadth/momentum measure based on advancing and declining issues, ended at -5,084, or a fresh low back to early-April 2020. read more Against this, the Nasdaq New High/New Low (NH/NL) index, a measure built around new yearly highs and lows, was unchanged on Monday at 24.1% read more : IXIC12212021 IXIC12212021 Of note, the Nasdaq NH/NL index bottomed at 12.5% on December 6, and then reclaimed its 10-day moving average (DMA) on December 10. This short-term moving average has now turned up, and the measure itself is showing a bullish convergence with the IXIC. In any event, traders will be watching for these measures to sync-up together. That is, for the McSum to begin to rise with the NH/NL index, and reclaim its 10-DMA, or for the NH/NL index to resume a decline, in-gear with the McSum. With this, there may be greater confidence in the Nasdaq"s next major move. Meanwhile, readings on the NYSE are showing a similar picture. On Monday, the NYSE McSum ended at its lowest level since April 2020. However, the NYSE NH/NL index, which also bottomed on December 6, and is also above its rising 10-DMA. And, the NYSE measure did tick down Monday for the first time in 10 sessions. This as the NYSE Composite (.NYA) closed below its 200-DMA. read more (Terence Gabriel) ***** FOR TUESDAY"S LIVE MARKETS" POSTS PRIOR TO 0900 EST/1400 GMT - CLICK HERE: read more Terence Gabriel is a Reuters market analyst.
