This weekends version of the Weekend Research will focus back on the fintech sector that had a bad week after some disappointing quarterly results. The market is still jittery about the sector following the problems in 2016 and it doesn't take much in the way of disappointment for investors to dump the stocks whether rational or not. LendingClub (LC) - the leading online lending marketplace reported a solid Q4, but the market wasn't happy with the Q1 guidance. LendingClub trimmed about 6% of the lower quality loans on the platform in early January and the market apparently wasn't prepared. Regardless, the company is on pace to approach $600 million in revenues for 2017 making the stock extremely appealing with an enterprise value of $1.4 billion. The stock fell back to support at $5.60. More research: LendingClub: Bringing Back The SizzleOnDeck Capital (ONDK) - the real issue during the week was OnDeck Capital. The small business lending platform took a large provision of $19 million spooking shareholders. The market missed that OnDeck now has record loans under management, origination volume, and gross revenue. Due to these factors, the guidance remained on target with 2017 revenues around $382 million. The stock is only worth less than 1x sales. The market is far too bearish on this concept. Square (SQ) - the mobile payments provider still trades near the highs around $14.50. Valuation remains highly stretched, but Citibank assigned a $20 price target. The target provides big upside on Square, but the returns will struggle up at those levels. The company reports Q4 earnings on Wednesday so hopefully this one won't disappoint. Nothing this week changes the potential on the fintech sector. The sector remains relatively new and is bound for bumps along the way. Use weakness in the sector as an opportunity.
