Looking back over the past 4+ years of the bull market.
Each time the 50-day SMA has rolled over as the SP-500 price initially lost the 50-day SMA it then quickly regained it. So... if the SP-500 is to break back under the 50-day SMA I see the market will sell-off extremely hard in a crash type fashion.
So the SPX 1678 area is where I would place stops on any remaining IT long positions.
