How Will AutoZone Stock React To Its Upcoming Earnings?

AutoZone (NYSE:AZO) is expected to report its earnings on Tuesday, September 23, 2025. Autozone’s revenues are projected to come in at about $6.25 billion per consensus estimates, up by about 1% compared to last year, while earnings are expected to come in at about $51 per share, roughly flat compared to last year. While revenues are likely to be driven by relatively stable same-store sales and ongoing store expansions across domestic and international markets, margins are likely to face pressure on account of being impacted by higher inventory shrink, a larger mix of commercial sales, which have lower margins, and also due to new distribution center startup costs. The company has $71 billion in current market capitalization. Revenue over the last twelve months was $19 billion, and it was operationally profitable, with $3.7 billion in operating profits and net income of $2.6 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.

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.

AutoZone’s Historical Odds Of Positive Post-Earnings Return

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

• There are 20 earnings data points recorded over the last five years, with 7 positive and 13 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 7 positive returns = 3.7%, and median of the 13 negative returns = -2.8%

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.
