All measured sympathy peers for RBLX
Every peer below passed the gates — enough events, direction consistency well above a coin flip, and a move meaningfully bigger than its normal day. Nobody else publishes this measurement; it exists because EarningsWatcher computes it from every RBLX report, with the peer's own earnings days and heavy market days excluded.

Why trade the peer instead of RBLX itself?
Options on RBLX are expensive into the print — the expected move is priced in, and implied volatility collapses the moment results land. RIOT has no event that day: its options are priced for a normal session, and measured across our pairs the median change in peer IV through a reporter's print is roughly zero. The sympathy trade turns RBLX's report into a position with a normal-day hurdle instead of an event-premium hurdle. New to the concept?

Frequently asked questions
Which stocks move when RBLX reports earnings?
Measured over up to ten years of RBLX's earnings days, the strongest sympathy peer is RIOT: same direction as RBLX's reaction in 89% of 9 tracked reports, median same-day move ±7.3%. Other quality-gated peers: MARA, CLOV — their full statistics are on the member board.
Are stocks like RBLX worth watching on its earnings day?
That is exactly what a sympathy play is: RBLX's report reprices companies with the same customers and economics, so 'stocks like RBLX' often move the same day — without an earnings event of their own. The size is usually smaller than RBLX's own move (RIOT: ±7.3% vs a normal day ×2.2), but the peer's options carry no event premium, so there is no IV crush to pay.
Is RIOT correlated with RBLX?
On RBLX's earnings days specifically, yes, historically: 89% same-direction over 9 events after excluding RIOT's own earnings window and heavy market days. General day-to-day correlation is a different (weaker) question — the earnings-day link is the tradeable one.
What is a sympathy stock?
A sympathy stock moves on another company's news rather than its own — here, RIOT reacting to RBLX's earnings. EarningsWatcher measures these relationships event by event and gates them for sample size, direction consistency and amplification; see the full guide to sympathy plays.
