270.54 = SPY 15-week sma above vs 270.36 = Tuesday hod, so far
chart #1 - SPY weekly with 15,2 BB and 21,2 BB:
* note the RSP price action in the recent 45 minutes is not confirming the intraday SPY price action, fwiw ( Not weighted vs. Weighted )...
see chart #2 for the observations below
at this moment, 13 of the top 25 most heavily weighted stocks in the SPX are more than 1% up on the day
the top 25 stocks account for 34% of the daily SPY price action, while they account for 5% of the RSP price action ... participation by the majority of the index components is very narrow on today's price advance .. you be the judge if this condition is durable
chart #2 - daily RSP to SPY ratio:
it is optimal though not necessary for the durability of future price advances if the RSP leads the SPY price action, which represents broadening participation by the majority of the 500 stock components in the S&P 500 index
* in years past, Arthur Hill would routinely blog post at StockCharts.com that it is bullish for SPY price action when the RSP to SPY ratio resided above its 120-day sma
times have changed, because that has not been necessary in the 2016 to 2018 period
the ratio did actually help us traders in January 2018 with being cautious about the prospects for continued SPY price upside durability
