After another weak day in the markets, the Dow finds itself over 200 points from the magical 20,000 level. Interesting plays for Tuesday are as follows:Under Armour (UA)(UAA) - another ugly day as the A shares hit a new multi-year low. The C shares appear to be holding the previous lows above $24. The recommendation remains to play the $3.50 gap in the shares that have no difference other then worthless voting rights. More signs of weakness with the Curry 3 sales should be no surprise as Steph isn't putting up the MVP numbers from last year and possibly isn't the best player on the team with the addition of KD. Some people still suggest that Nike (NKE) planted KD at Golden State to knock down the runaway popularity of Curry. Though far fetched the move has hurt Under Armour sales. Acacia Communications (ACIA) - close to breaking the downtrend, but the risk is still to the downside. Twilio (TWLO) - another small gain on a weak day reaffirms the theory that the cloud communications provider has hit the lows. CSX Corp. (CSX) - the railroad operator managed to slide up 4% to new highs. Somehow BMO Capital raised the price target to an incredible $55. Yes, the analyst raised the target from $38 or 45% due to the thoughts that Mantle Ridge LP can install 72-year old Hunter Harrison as the CEO of CSX. As well, the analyst sees the stock reaching over $80 in the medium term based on the incredible thought that the railroad operator can reach an operating ratio below 60%. The odds this happens don't appear so great. Do not drink the kool-aide. 3D Systems (DDD) - as predicted, the better play was Stratasys (SSYS) that only declined a fraction of the 3.1% loss of 3D Systesm.
