95 reports on this security, the newest 28 listed. An implied move is served from 2019-10-30 and the straddle returns from 2021-06-07, so n sits near its floor for names with a shorter history. One report a quarter, so the one-session windows never overlap and n is already the effective n.
core.earnings_events read point-in-time: the vintages that existed at the end of the as-of day, with the quarter and epoch flags re-derived over that set (migration 7a5161d44b1e). A past report is one that happened - the only date for its quarter, or one carrying actual EPS.
Short & borrow
from technicals: Fee 0.35% on 2026-09-18, with the price 21.45% below its 252-session high on 2026-09-18.
Ranked 5 of 16 names with a snapshot on 2026-09-18. A peer whose newest snapshot falls on a different day - older or newer - is listed with that day and excluded from the rank, never compared across days.
core.borrow_rates, the accrued snapshot series. The percentile is the house midrank - (below + half the ties) / n - over one reading per ET day, computed in SQL and NULL below its floor. Fee rates sit on a general-collateral floor, so ties are the common case and the midrank is what keeps a floor reading from reading as the minimum.
