SPX has long been rallying since the bottom back in march and is now very close to the point it was prior to covid. now given the RSI is high and looks like it may be about to turn, the MACD looks like its about crossover and the candles show signs of a reversal ('big' green, followed by a reaching hammer followed by a 'big' red) Id say it is highly likely that we will start to see some selling of SPX the last area of resistance was around 3277 so a conservative target of 3300 seems reasonable.
