Right now, I would be concerned about downside if the Nasdaq were to close up on a day when the total share volume for the day shrunk to about 1.66 billion shares.
The Nasdaq has immediate resistance in the 2242-2356 area with a focus of resistance 2253-2310. Immediate Nasdaq support is 2169-2088.
The S&P 500 has immediate closing resistance in the 1253-1273 area. The next resistance is 1300-1341. Immediate support remains 1238-1223. Cherney is Market Analyst for Standard & Poor's
