All measured sympathy peers for ZBH

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

Why trade the peer instead of ZBH itself?
Options on ZBH are expensive into the print — the expected move is priced in, and implied volatility collapses the moment results land. MDT 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 ZBH'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 ZBH reports earnings?
Measured over up to ten years of ZBH's earnings days, the strongest sympathy peer is MDT: same direction as ZBH's reaction in 71% of 34 tracked reports, median same-day move ±1.0%.
Are stocks like ZBH worth watching on its earnings day?
That is exactly what a sympathy play is: ZBH's report reprices companies with the same customers and economics, so 'stocks like ZBH' often move the same day — without an earnings event of their own. The size is usually smaller than ZBH's own move (MDT: ±1.0% vs a normal day ×1.3), but the peer's options carry no event premium, so there is no IV crush to pay.
Is MDT correlated with ZBH?
On ZBH's earnings days specifically, yes, historically: 71% same-direction over 34 events after excluding MDT'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, MDT reacting to ZBH'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.
