How To Trade Marvell Stock Ahead Of Earnings?

Marvell Technology (NASDAQ:MRVL) is set to report its Q2 2026 earnings on Thursday, August 28, 2025 (January fiscal year). Revenues are projected to grow 58% year-over-year to about $2.01 billion, while earnings are estimated to come in at about $0.67 per share. Growth is likely to be driven by strong AI demand in the data center end market, where Marvell’s custom silicon offerings and electro-optics products are seeing strong uptake. The custom silicon story could drive growth in AI over the long-run, as hyperscalers increasingly want tailor-made chips rather than standardized GPUs as they look to balance performance, power efficiency, and cost for their own AI models.

Marvell has $63 billion in current market capitalization. Revenue over the last twelve months was $6.5 billion, and it was operationally profitable, with $40 million in operating profits and net income of $-491 million. While a lot will depend on how results stack up against consensus and expectations, understanding historical patterns might just turn the odds in your favor if you are an event-driven trader.

There are two ways to do that: understand the historical odds and position yourself prior to the earnings release, or look at the correlation between immediate and medium-term returns post earnings and position yourself accordingly after the earnings are released. That said, if you seek upside with lower volatility than individual stocks, the Trefis High Quality portfolio presents an alternative – having outperformed the S&P 500 and generated returns exceeding 91% since its inception.

Marvell Technology’s Historical Odds Of Positive Post-Earnings Return

Some observations on one-day (1D) post-earnings returns:

• There are 17 earnings data points recorded over the last five years, with 6 positive and 11 negative one-day (1D) returns observed. In summary, positive 1D returns were seen about 35% of the time.
• However, this percentage decreases to 25% if we consider data for the last 3 years instead of 5.
• Median of the 6 positive returns = 13%, and median of the 11 negative returns = -5.6%

Additional data for observed 5-Day (5D) and 21-Day (21D) returns post earnings are summarized along with the statistics in the table below.

Correlation Between 1D, 5D, and 21D Historical Returns

A relatively less risky strategy (though not useful if the correlation is low) is to understand the correlation between short-term and medium-term returns post earnings, find a pair that has the highest correlation, and execute the appropriate trade. For example, if 1D and 5D show the highest correlation, a trader can position themselves “long” for the next 5 days if the 1D post-earnings return is positive. Here is some correlation data based on a 5-year and a 3-year (more recent) history. Note that the correlation 1D_5D refers to the correlation between 1D post-earnings returns and subsequent 5D returns.

Is There Any Correlation With Peer Earnings?

Sometimes, peer performance can have an influence on post-earnings stock reaction. In fact, the pricing-in might begin before the earnings are announced. Here is some historical data on the past post-earnings performance of Marvell Technology stock compared with the stock performance of peers that reported earnings just before Marvell Technology. For fair comparison, peer stock returns also represent post-earnings one-day (1D) returns.
