Earnings Volatility Watch: What To Expect From Sandisk and 5 Mag Seven Stocks This Week

Five of the Magnificent Seven stocks — Alphabet Inc. (NASDAQ:GOOGL), Microsoft Corp. (NASDAQ:MSFT), Amazon.com Inc. (NASDAQ:AMZN), Meta Platforms Inc. (NASDAQ:META) and Apple Inc. (NASDAQ:AAPL) — report earnings between Tuesday and Thursday this week.

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.

• Ranked seventh among the best-performing S&P 500 stocks of 2026, Seagate is up 112.88% YTD, with nearly half that return (49.65%) coming in April alone as the AI memory cycle has lifted the entire storage cohort.

• Options markets are bracing for an 11.33% post-print swing, or roughly $15.9 billion. Western Digital reports the day after spinning off SanDisk in February 2025 — making the back-to-back prints twin reads on the same NAND cycle.
