Another interesting day in the market leads to plenty of interesting moves for tomorrow:Novavax (NVAX) - the biotech stock has rebounded to $1.43 on expectations of some good news from the JP Morgan Healthcare conference. The company presents on January 12 at 9:30am Pacific Time. Novavax only set up plans for the workforce reduction back in November along with the Q3 earnings report. Fade any rally as the company is unlikely to break any news on Thursday. Fitbit (FIT) - the fitness tracking stock was hit on a warning from Cleveland Research. The note repeats previous fears and doesn't account for the strong app downloads over the holidays. The stock closed down nearly 6% to $7.33 on news that repeats the same thesis that pushed stock down at these level in first place. As some not giving up on the fitness tracking sector, I'm still lurking around the stock with no desire to pick a bottom. Acacia Communications (ACIA) - the stock plunged nearly 10% to a new closing low. The past hot IPO hasn't recovered since the secondary offering at $100 back in October. Based on the chart, the optical equipment provider probably plunges to $50, if not down to $40. Twilio (TWLO) was a similar hot IPO that didn't stop until the price got down to the initial trading levels. 3D Systems (DDD) gave up gains from yesterday as predicted. Stratasys (SSYS) remains the better play in the 3D printing sector if somebody wants to invest in a 2018 turnaround in the sector.
