Stocks to watch for Tuesday:Red Hat (RHT) - stock appears poised for a breakout after Q4 revenues beat estimates by $10 million. The open source software provider has traded sideways for nearly 2 years now. Red Hat isn't cheap with '18 EPS estimates at $2.60, but the stock appears headed higher regardless. The market likes round numbers so a rally to $100 seems likely. Fitbit (FIT) - the fitness tracking stock had a nice 5% bounce today. The release of the Alta HR early was the catalyst, but this wearable shouldn't really move the needle. Though solid execution and continuous product updates will produce a higher stock price in the long term. The question now is whether Fitbit hit a bottom last week. The stock needs some follow through this week, if that is the case. Weatherford (WFT) - the oil services stock again bounced off $6. Despite weak oil prices, oil services demand is booming in the US and Weatherford remains poised for a turnaround. The stock appears headed to $8. Twitter (TWTR) - the stock held right at $15 showing signs of a bottom. The indication that the social-media platform is about to implement premium services for fees is a game changer. Remember that LinkedIn was bought for $26 billion by Microsoft (MSFT) and had far fewer users, but utilized subscriptions to boost the value. Alexion Pharma (ALXN) - stock bounced right off $115 today signaling a strong reversal in the stock. Hard to see this stock heading any lower.
