6 week consolidation followed by a downtrend confirmation last week suggests a 10% dip in SPX before Christmas. MACD crossover signaling a downtrend about to emerge also. Monthly prices at the end of 2017 closed above the upper Bollinger. Then have dropped below this month. This indicates a likely drop in price. Look for a drop below the 2600 resistance level to see more lows. Despite markets rallying this week I think we are headed for more of a drop.
