How Will Micron Technology Stock React To Its Upcoming Earnings?

Micron Technology (NASDAQ:MU) is expected to report its earnings on Tuesday, September 23, 2025. Earnings for the quarter are projected to come in at about $2.85 per share, up from $1.18 per share in the year-ago quarter, per consensus estimates. Revenues are likely to come in at about $11 billion, up 43% year-over-year. Growth is likely to be driven by demand for AI infrastructure, which is boosting sales of high-bandwidth memory products, also referred to as HBM. During Q3 FY’25, HBM revenue surged nearly 50% quarter-over-quarter, boosting the business to a $6 billion annualized run rate.

The company has $152 billion in current market capitalization. Revenue over the last twelve months was $34 billion, and it was operationally profitable, with $7.6 billion in operating profits and net income of $6.2 billion. 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. related Micron Stock At 10x Earnings: AI’s Best Bargain?

• Median of the 7 positive returns = 8.6%, and median of the 12 negative returns = -4.2%

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.
