Shares of D-Wave Quantum Inc. climbed roughly 4% in early trading Wednesday after two brokerages issued upbeat research notes on the quantum-computing company. B. Riley Securities lifted its 12-month price target to $22 from $20 while maintaining a Buy rating, citing a larger total addressable market, accelerating adoption of the Advantage2 system and a cash runway of more than four years supported by $815 million on the balance sheet. Earlier in the day, Canaccord Genuity began coverage of D-Wave with a Buy recommendation and a $20 target, saying the firm is well-positioned to commercialize quantum annealing solutions. The back-to-back endorsements extended a rally that has pushed the stock up about 30% in the past month.
