The Nasdaq (first chart below) is so far hanging on between two uptrend lines from August; whichever line the index breaks through could be the key. 2080 is critical support, and 2115 is critical resistance. The index is deeply oversold; can the big jobs report tomorrow provide a bounce? The S&P 500 (second chart) has important support at 1183, with 1172-1175 and 1160-1163 below that, and resistance is 1193 and 1198-1200. The Dow (third chart) has support at 10,575-10,583 and 10,530-10,540, and resistance is 10,640-10,650 and 10,700-10,710.
