Investing.com -- Roblox was downgraded by both BMO Capital Markets and Deutsche Bank on Friday after a disappointing second-quarter report and outlook, with analysts warning its platform transition will take time to pay off and competition is mounting. Deutsche Bank analyst Benjamin Black downgraded Roblox to Hold from Buy, lowering his target to $38 from $56. Deutsche Bank said improved discovery, safety standards and growth among over-18 users can expand Roblox's addressable market, while BMO flagged rising age-verification rates. But both cut estimates, and Deutsche Bank expects shares to "remain range-bound until UCAN monetization stabilizes."
