What Just Happened To Marvell Stock?

Shares of Marvell Technology (MRVL) fell 17.2% over the five trading days from October 9 to October 16, 2026. The broader market saw far less movement during that window, with the S&P 500 losing 1.9%. The stock first slipped the day after its October 6 Investor Day, an event where management actually raised its revenue outlook for fiscal 2028. So how hard was the week for Marvell, and what does its price still appear to assume?

Marvell’s Worst Day Came On October 14

The steepest drop for Marvell occurred on October 14, when shares lost 8.7% in a single session. Other chip stocks also had a weak week over those same dates. Advanced Micro Devices went down 13.0% and NVIDIA fell 6.6%, yet Marvell experienced a deeper decline than both. Earlier in the month, the stock had risen 5.8% on the day of the Investor Day. Ultimately, the week’s fall more than erased that gain.

What Marvell’s Price Still Appears To Assume

Even after taking this hit, Marvell commanded a steep premium at the October 16 close. The stock traded at 77.4 times its earnings over the past twelve months, well above the 22.9 multiple for the S&P 500. Valuations at that level appear to assume growth far beyond today’s results, and management has explicitly put a number on that growth. Executives used the Investor Day to raise the fiscal 2028 revenue outlook to about $20 billion, up from about $18 billion provided during the August 27 earnings call. They also set a fiscal 2031 revenue target of $70 billion to $90 billion.

For context, Marvell generated $9.45 billion in revenue over the past twelve months. Meeting the new outlook will require the company to more than double those sales by fiscal 2028.

Marvell’s Latest Results Stand Where They Were

The company reported no new financial results during the week, leaving its latest quarter exactly as it looked before the stock fell. In fiscal Q2 2027, the quarter ended August 1, 2026, Marvell posted revenue of $2.74 billion, a 36.5% increase from a year earlier. The chip designer also kept more of each sale as profit. Its operating margin came in at 16.7%, up from 14.9% a year earlier. Data center served as the largest end market, making up 79% of total revenue according to management on the August 27 call. On the liquidity side, free cash flow over the past twelve months reached $1.72 billion, rising from $1.53 billion a year earlier.

Looking ahead to fiscal Q3 2027, management guided to revenue of $3.15 billion, plus or minus 5%. How actual revenue stacks up against that guide is the number to watch at Marvell’s next report, expected on or around November 30, 2026.
