All measured sympathy peers for BMO
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 BMO report, with the peer's own earnings days and heavy market days excluded.

Why trade the peer instead of BMO itself?
Options on BMO are expensive into the print — the expected move is priced in, and implied volatility collapses the moment results land. BAC 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 BMO'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 BMO reports earnings?
Measured over up to ten years of BMO's earnings days, the strongest sympathy peer is BAC: same direction as BMO's reaction in 66% of 38 tracked reports, median same-day move ±1.3%.
Are stocks like BMO worth watching on its earnings day?
That is exactly what a sympathy play is: BMO's report reprices companies with the same customers and economics, so 'stocks like BMO' often move the same day — without an earnings event of their own. The size is usually smaller than BMO's own move (BAC: ±1.3% vs a normal day ×1.7), but the peer's options carry no event premium, so there is no IV crush to pay.
Is BAC correlated with BMO?
On BMO's earnings days specifically, yes, historically: 66% same-direction over 38 events after excluding BAC'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, BAC reacting to BMO'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.
