S&P500 Technical Analysis: Getting ready for a Friday drop

• The S&P500 is trading near its all-time-high but bulls have a hard time to extend the main bull trend. 
• After the rising wedge formation (blue dotted lines) the S&P500 is now trading sideways for the second consecutive day. The simple moving averages have turned flat and any rally seems to become a selling opportunity. Downside target remains 2,835.25. 
• A bull breakout above 2,875.50 would invalidate the short-term bearish bias.
