Rumble (RUM -1.76%) stock is sinking in this week's trading. The company's share price was down 12.5% from last week's market close of as of 1 p.m. ET Thursday, according to data from S&P Global Market Intelligence.

Rumble stock is losing ground this week following recent interest rate news from the Federal Reserve. While the Fed announced the 25-basis-point interest rate cut that investors anticipated yesterday, Chairman Jerome Powell delivered commentary that worried investors.

At its meeting yesterday, the Federal Reserve delivered its third interest rate cut since September. But Powell indicated that the central banking authority would take a more cautious approach to cutting rates next year.

While many investors had been looking forward to a full-point rate cut across four intervals next year, it now looks like only two cuts of 25 basis points are slated to occur. Things could still change on that front, but the market reacted negatively to the news and saw big sell-offs yesterday. Companies with growth-dependent valuations, including Rumble, were particularly hard hit.

Rumble is an upstart player in the highly competitive video-streaming market. With its third-quarter report, the company showed revenue of $25.1 million -- up 39% year over year and 12% on a sequential quarterly basis. Meanwhile, the business posted a net loss of $31.5 million, increasing from a loss of $29 million in last year's third quarter.

Despite tailwinds connected to the U.S. election cycle, the business has been posting somewhat uninspiring engagement and monetization numbers. The company closed out Q3 with only 67 million average monthly active users, and average revenue per user came in at $0.33 -- down from $0.37 per user in Q2. Thus far, the business does not appear to be scaling effectively -- and there's a significant risk that engagement momentum will weaken now that election season has concluded.
