Freeport-McMoRan Inc. is currently running 52.6% annualised volatility over the last 21 sessions. Measured against FCX's own 13 years of daily returns rather than a market-wide average, that is the 71st percentile — a little above its own norm, against a typical reading of 41.8%. 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.

FCX is trading -13.1% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -42.5%, and the deepest was -74.3% in 2015. The current pullback is therefore shallower than what this stock gives back in a typical year, which is context worth having before treating it as a dislocation.

Price sits +11.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 67th percentile — a somewhat wider gap than its own norm. Over the past year FCX closed higher on 55% of sessions, and it is currently 1 session into a falling streak.

On September specifically: over 13 years of records, FCX finished the month higher 4 of 13 times, with a median return of -4.0% and an average of -1.9%. Its strongest month historically has been February at +7.8% on average, its weakest January at -3.5%. 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: FCX has opened more than 2% away from the prior close in 225 of 3,267 sessions (6.9% of the time), with the largest gaps running +10.6% and -6.8%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

Across the last 3 dated reports on file, FCX moved an average of 1.9% in the session after earnings, closing higher 1 of those 3 times, with a median move of -1.8% and a largest of +2.1%.

All figures computed from 3,268 daily closes between 2013-09-18 and 2026-09-16, split-adjusted, recomputed daily. Percentiles are against FCX's own 13-year history, not a peer group or index.
