Options contracts tied to Alcoa Corp. suggest the aluminum producer's stock could move roughly 4.9% around its earnings announcement scheduled for July 16, after the market close. That estimate is derived from option prices and reflects the market's expectation for how much the shares might swing on the news.
The company's stock has tended to deliver results that sometimes diverge materially from what options implied. Across the eight most recent earnings releases documented here, the actual percentage change in Alcoa's share price exceeded the options-implied move in four instances and fell short in the other four.
Below is a chronological record of the actual moves versus the implied moves derived from options data:
- April 16, 2026: Stock fell 8.6% while options had implied a 5.5% move.
- January 22, 2026: Stock dropped 3.7% versus an implied move of 5.7%.
- October 22, 2025: Shares jumped 12.3% compared to an implied move of 6.0%.
- July 16, 2025: Stock declined 3.7% while options suggested a 6.5% move.
- April 16, 2025: Stock rose 3.3% versus an implied move of 6.5%.
- January 22, 2025: Shares gained 1.3% against an implied move of 6.6%.
- October 16, 2024: Stock climbed 6.9% compared to an implied move of 5.3%.
- July 17, 2024: Shares fell 11.6% while options data indicated a 3.9% move.
This pattern underlines a degree of unpredictability in the stock's reaction to quarterly results. On several occasions the market's pricing of options understates the eventual move, while in other quarters the options market suggested a larger swing than actually occurred.
Investors and market participants watching the materials and metals complex may interpret the options-implied figure as a gauge of near-term risk around the report, but the historical record here demonstrates that actual outcomes can deviate materially from those expectations.
