Roblox (RBLX) usage continues to slip lower, with no signs of "firming" as Q4 starts, Wedbush Securities said in a Thursday note.

Weekly concurrent users declined by 14%, from a 17% fall in the previous week, while proxy daily active users were down 14% for the same two-week period, the brokerage said. Both metrics stood at their lowest levels since June, Wedbush noted.

A portion of the declines could be attributed to back-to-school seasonality, given similar trends a year earlier, the investment firm said, noting that it is waiting on engagement-to-bookings conversion to be more constructive.

Wedbush has a neutral rating and $48 price target on Roblox.
