The chart isn't to show you'll make money holding SPY indefinitely (though all indications are you would). The point is the current 'bubble' has only recently departed from ordinary SPX trend. The take-away being, after a pivot into a bubble (which I argue coincides with Nov 2016), be bullish for anything beyond a few days time frame until growth slows. Red weeks are rare. And then get scared when growth slows and then flat-lines.According to your chart though, there has never been a top. I'm not sure that it applies to a trading strategy. I have said before that there is only one 100 percent winning system and that is buy the broad index and have a lot of time. Your comments please
