The S&P is now continuously making all time high in its freshest burst of price discovery. This is more of a speculative trading pattern, a rising wedge which indicates there could a break down to 2950, and maybe down to 2750 support.
However, in strong markets, what tends to happen is price breaks out upwards out of a rising wedge. This would indicate serious strength in the market, and suggest price discovery isn't ready to slow down yet.
