Akebia Therapeutics (NASDAQ: AKBA) , Momo (NASDAQ: MOMO) , and Switch (NYSE: SWCH) were among the top performers. Investors have been pleased overall with the current state of affairs on the economic front, and those calling for a Goldilocks-like middle ground between a recessionary downturn and a too-fast growth spurt that could spur inflation have liked what they've seen. User counts soared by two-thirds to 13 million, and Momo showed extremely high adoption of its value-added services, including membership subscription sales.
