Financial and Business Position

As a high-multiple growth name, Roblox's shares are sensitive to interest rates and to shifts in sentiment toward communication services.

Because so much of such a company’s value rests on cash flows expected years into the future, a higher discount rate reduces the present value of those Earnings and the stock derates. Roblox, with a valuation that leans heavily on continued growth, fits that description, and it fell alongside other richly valued names as rates backed up. As a communication-services stock with a growth valuation, Roblox was squarely in the part of the market being sold.
