The Nortel revenue miss should be taken seriously; the stock has been a real leader in the one sector that has been relatively immune to selling. We’ll watch how well the market absorbs the news tomorrow.

What a disappointing finish. What started out as a potential follow-through day (a 1%+ gain on volume that is higher than the day before), turned into a sell-off on rising volume. Not something we want to see this early in the rally. The Nasdaq continues to struggle with its 38% retracement level of 3494 and the August bottom of 3521. The index may also be struggling with its October 1998 trendline here. To the downside, we want to stay above the Nasdaq’s September downtrend line at about 3300.

The S&P 500 cannot close below its 1994 logarithmic trendline at about 1350 by more than 2%, or 1323. 1380 could provide some support on the S&P. The S&P broke through its secondary downtrend line at about 1405 this morning, but then closed back below it. 1420-1425 could also pose some resistance.

The ISDEX continues to run into resistance at the 700 level. Next resistance is 725-750, and first support is 650, where we closed today. The Dow is back above 10,300 resistance, but turned back at its secondary downtrend line just above 10,400.
