This is purely my personal opinion and analysis on SPX500. After breaking past the 50 day SMA around Point A, seller are exhausted and the bulls continued and tried to break the ceiling at 2135 at Point B but to no avail. Thus, the buyers gave up at the top and we end up with a lower high at Point C. My prediction would be that the sellers will break below the 50 Day SMA and push for a retest of 2040 and even try for a break through that.
