This was one of those pre-holiday trading sessions where the closing bell outcome depended on which index you looked at. Tech stocks were up with the S&P 500, but the DJIA was a mixed bag throughout the trading day. This appears to have been a 3-year high for NASDAQ and a 2-year high for the S&P. As far as the holiday-shortened week is concerned, today may be a blueprint for trading here in the U.S. and abroad.

Here were today's unofficial closing bell levels:

Dow Jones 11,478.13 -13.78 (-0.12%)
S&P 500 1,247.08 +3.17 (0.25%)
Nasdaq 2,649.56 +6.59 (0.25%)

The market won't let QE2 go ahead of the G20 meetings. Now the talk is that the second wave of quantitative easing is mostly priced in, as well as fears of ongoing currency wars. The markets were mixed at the open, but shares were lower by the close on the DJIA, and trying to hold on to positive in the NASDAQ and S&P500.

Dow Jones 11,132.26 -14.31 (-0.13%)

They don't all work out. After gapping up in June, Applied Signal Technology's (APSG ) stock chart has misbehaved, which is why I'm placing a hold on the company's shares, first recommended on June 22, 2009, at a price of $24.34.

Despite a decent third quarter EPS performance of 25 cents, 1 cent below the First Call Q3 EPS estimate of 26 cents, institutional investors have continued to exit the stock, with the stock recording several dips below the key, 50-day moving average line.

It goes without saying that the tech-based intelligence, surveillance, and security systems sector is favored here, and with the aforementioned in mind Applied Signal Technology (NASDAQ: APSG) is worth a review.

In general, analysts expect strong demand for Applied's broadband communications equipment and its new Model 680 Raider product to continue.
