RE:NVA technicals 50 RSI on daily chart is short term reversal territory, if it slides lower it would confirm my speculation that larger picture XLE is showing energy due to pullback / bearish and nimble traders will be short or on sidelines.
MACD is lagging indiator so confirms short term indicators after the fact.
Where XLE goes, likely CDN energy follows this time:
