MarketAxess Holdings Inc. is currently running 2.2% annualised volatility over the last 21 sessions. Measured against MKTX's own 13 years of daily returns rather than a market-wide average, that is the 0th percentile — unusually subdued by its own history, against a typical reading of 26.9%. The distinction matters because a number that looks calm for one stock is turbulent for another, and the absolute figure on its own tells you neither.

MKTX is trading -72.1% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -27.6%, and the deepest was -48.6% in 2023. The current drawdown is already deeper than this stock's typical annual low point, which puts it in the part of its range where past recoveries began — and where past declines also continued.

Price sits +5.3% from its 200-day moving average. Against every other day in its history, that gap ranks at the 53rd percentile — close to the gap it normally carries. Over the past year MKTX closed higher on 51% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 14 years of records, MKTX finished the month higher 9 of 14 times, with a median return of +3.2% and an average of +3.9%. Its strongest month historically has been July at +6.5% on average, its weakest September at -4.5%. Seasonality is a weak signal on its own — a decade is a small sample and regimes change — but it is a real distribution rather than a rule of thumb.

Overnight risk is measurable too: MKTX has opened more than 2% away from the prior close in 94 of 3,268 sessions (2.9% of the time), with the largest gaps running +27.3% and -9.9%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,269 daily closes between 2013-10-15 and 2026-10-14, split-adjusted, recomputed daily. Percentiles are against MKTX's own 13-year history, not a peer group or index.
