All measured sympathy peers for PRKS

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

Why trade the peer instead of PRKS itself?
Options on PRKS are expensive into the print — the expected move is priced in, and implied volatility collapses the moment results land. HPQ 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 PRKS'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 PRKS reports earnings?
Measured over up to ten years of PRKS's earnings days, the strongest sympathy peer is HPQ: same direction as PRKS's reaction in 88% of 8 tracked reports, median same-day move ±3.5%. Other quality-gated peers: COF — their full statistics are on the member board.
Are stocks like PRKS worth watching on its earnings day?
That is exactly what a sympathy play is: PRKS's report reprices companies with the same customers and economics, so 'stocks like PRKS' often move the same day — without an earnings event of their own. The size is usually smaller than PRKS's own move (HPQ: ±3.5% vs a normal day ×2.6), but the peer's options carry no event premium, so there is no IV crush to pay.
Is HPQ correlated with PRKS?
On PRKS's earnings days specifically, yes, historically: 88% same-direction over 8 events after excluding HPQ'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, HPQ reacting to PRKS'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.
