Lake Street analyst Mark Argento believes the focus in 2018 for TheStreet is "solving the puzzle for revenue growth." The business-to-business segment continues to increase thanks to the fast-growing BoardEx business, and there are signs that the declining business-to-consumer business is troughing, Argento tells investors in a post-earnings research note. He believes TheStreet continues to trade at a "throwaway valuation" and would like to see management take advantage and "fire up its buy-back." Argento keeps a Buy rating on TheStreet with a $3 price target following the company's Q4 results.
