This is what you need to know here and now:
Axiomatic is that the advance is good until the MACD turns down. CHECK. -> MACD still good.
Further, Overextended on the RSI is + 70 or so, thus with the RSI's for those four indexes in the Mid-50's, it does not dictate that this ETF is vulnerable to a heavy correction. CHECK. -> RSI overextended NOT. Thus this is a GOOD CHART, not showing any vulnerability to a serious correction yet.
Simply, it doesnt take a Weatherman to tell which way the wind is blowing.
