The algorithms, specifically, the Precise Signal is at it again. The signal is a SELL for Northrup Grumman. Historically, the Precise Signal indicating a SELL sees the stock move down an average of 10%. In fact the minimal drop for this signal with NOC is 7%. Considering Friday saw the stock drop 3% off its high, another 7% (or more) would be huge.
My MTFs also signaled SELLs, but since the Precise is built off of them this a not a surprise. For you technical junkies, the full analysis with each target is at my site for free as always
