All measured sympathy peers for TSHA

Nobody else publishes this measurement; it exists because EarningsWatcher computes it from every TSHA report, with the peer's own earnings days and heavy market days excluded.

Why trade the peer instead of TSHA itself?
Options on TSHA are expensive into the print — the expected move is priced in, and implied volatility collapses the moment results land. SOUN 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 TSHA's report into a position with a normal-day hurdle instead of an event-premium hurdle. New to the concept? Read what a sympathy play is, then see this week's live board.
Frequently asked questions
Which stocks move when TSHA reports earnings?
Measured over up to ten years of TSHA's earnings days, the strongest sympathy peer is SOUN: same direction as TSHA's reaction in 80% of 10 tracked reports, median same-day move ±4.9%. Other quality-gated peers: BNTX, TGTX, AXSM, EW — their full statistics are on the member board.
Are stocks like TSHA worth watching on its earnings day?
Sometimes. Sympathy plays work best when the peer shares customers or economics with TSHA. TSHA's measured peers so far are statistical matches without a confirmed business link, so the edge is weaker: SOUN moved ±4.9% on TSHA's earnings days (×1.7 its normal day), but check what connects the two before trading it. The peer's options carry no event premium, so there is no IV crush to pay.
Is SOUN correlated with TSHA?
On TSHA's earnings days specifically, yes, historically: 80% same-direction over 10 events after excluding SOUN'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, SOUN reacting to TSHA'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.
