SPX vs SPY... compare both

I've mentioned before that I like to compare SPX ES and SPY together because they sometimes have differences. If one is buying the SPY etf, this could make a difference. The differences are usually slight, but are there.

In the charts below, notice that SPX made higher highs on the trendline but SPY made lower highs. Also the slope of the support trendline that connects the lows is steeper on the SPX than on SPY.
