So do energy supermajor Exxon Mobil Corp. (NYSE:XOM), pharma giant Eli Lilly & Co. (NYSE:LLY), payments duopoly Visa Inc.(NYSE:V) and Mastercard Inc.(NYSE:MA), and industrial bellwether Caterpillar Inc.(NYSE:CAT).

These 10 companies reporting this week represent roughly $18.59 trillion in combined market capitalization, making the final week of April one of-if not the most-important of the Q1 2026 earnings season.

Yet, the loudest signal from the options market isn't coming from any of them.

The Mega-Cap Stocks With The Biggest Implied Moves This Week

According to Benzinga Pro data, options markets are pricing the largest single-stock move not on a Big Tech name, but on a $150 billion NAND maker up 317% year-to-date: Sandisk Corp.(NASDAQ:SNDK).

The list spans cloud hyperscalers, AI infrastructure suppliers, semiconductor capital equipment, and the memory cohort that has rallied harder than any other tech sub-sector in 2026.

Implied moves measure the size of the price swing - up or down - that the options market expects, based on at-the-money straddle pricing ahead of the earnings date. A 16.57% implied move means options traders are positioning for an equal probability of a 16.57% gain or a 16.57% loss when results land.

Below are the 10 mega-cap stocks (market caps above $100 billion) with the largest implied post-earnings moves this week, ranked from smallest to largest, followed by the five Magnificent Seven names.
