While difficult to maintain the 30% growth experienced in 2018, Match Group should see sustainable mid to high teen revenue growth and high 30% margins going forward, Jefferies analyst Brent Thill tells investors in a research note. However, with the stock up 32% year-to-date, "further multiple expansion may prove difficult at these levels," adds the analyst. Nonetheless, Thill trusts Match's "history of quarterly execution" and the long-term "tailwinds at play. He expects the stock "to grind higher rather than fly higher" and keeps a Buy rating on the name with a $64 price target. It remains a top mid cap pick at Jefferies.
