It was an ugly day on Wall Street. Technicals were just so-so, and Apple Inc. (AAPL) certainly took the brunt of the abuse on Thursday, down 65 points. But there are both longs and shorts to be highlighted here. Embraer SA (ERJ) was all the way up to the 50’s in 2007, came down in a 5-wave decline to below 10 in 2009, broke back out in a 5-wave advance before moving into sideways action for the last couple years. It then moved up, down, back up, back down, tested the lows in the 21-2 zone a couple times, and on Thursday, it spiked 2.60 to 31.16, or 9%, on 3.1 million shares. That’s the best volume on an up-day in quite a long time. Let’s see if this stock can make it up to the next target at 35. Green Mountain Coffee Roasters Inc. (GMCR) is acting nicely. After being in a long-term, 3-wave decline, the fourth and fifth wave, which were kind of truncated, moved into a rising channel. A breakaway gap occurred on big volume, it moved up, then came down, went sideways and consolidated over the last 6-7 weeks, and on Thursday, it popped 2.70 to 43.78, or 6.57%, on 8 million shares, the best volume in a couple months. Look for a move up to test the high 40’s, low 50’s short-term. On the Short Side… Blue Nile Inc. (NILE) has been in a declining channel going back to 2010. Basically, this is a monster stock from 2007 when it reached 103.00. It went all the way down to the high teens, and then all the way back up to the high 60’s, rolled over, consolidated, and then broke down. It looks like the gap may be tested again. There’s support at the 30 zone. If it gets through that, look for something down around 26 short-term. Under Armour, Inc. (UA) formed a head-and-shoulder top, rolled over, snapped back to resistance, reached the channel top, rolled over, reached back and touched the top again, before rolling over again. On Thursday, it broke down and tested key, year-long support levels at around 44-44 1/2. If that breaks, this stock may get down into the low 40’s or less very soon.
