How Will 3M Stock React To Its Upcoming Earnings?

3M (NYSE: MMM) is scheduled to announce its earnings on Tuesday, October 21, 2025. This report is a significant event for traders, particularly those who leverage event-driven strategies.

Over the last five years, 3M’s stock has demonstrated a balanced reaction to earnings announcements, with an equal split of positive and negative one-day returns following the results. In 50% of instances, the stock saw a positive one-day return, with a median of 4.8%. Conversely, in the other 50% of instances, it experienced a negative one-day return with a median of -2.8%. This historical pattern suggests a notable degree of volatility and a lack of consistent upward or downward bias post-earnings.

For the upcoming third quarter of 2025, consensus estimates anticipate earnings of $2.07 per share on sales of $6.26 billion. This compares with the year-ago quarter’s earnings per share of $2.14, although current sales are expected to be higher than the prior year’s $6.07 billion.

While the actual financial results and their comparison to consensus and expectations will heavily influence the stock’s immediate reaction, understanding these historical patterns can provide valuable insights for event-driven traders. There are two primary approaches to consider:

• Pre-Earnings Positioning: Based on the historical odds, a trader might choose to take a position before the earnings release, anticipating a move (either positive or negative) and managing the associated risk given the 50/50 split in past performance.
• Post-Earnings Positioning: Alternatively, a trader could wait for the earnings release, analyze the immediate market reaction and the correlation between short-term and medium-term returns, and then position themselves accordingly after the announcement.

From a fundamental perspective, 3M currently holds a market capitalization of approximately $81 billion. Over the last twelve months, the company generated $25 billion in revenue. It demonstrated operational profitability with $4.8 billion in operating profits and a net income of $3.9 billion.

That being said, if you seek an upside with less volatility than holding an individual stock, consider the High Quality Portfolio. It has comfortably outperformed its benchmark—a combination of the S&P 500, Russell, and S&P MidCap indexes—and has achieved returns exceeding 105% since its inception. Why is that? As a group, HQ Portfolio stocks provided better returns with less risk versus the benchmark index; less of a roller-coaster ride, as evident in HQ Portfolio performance metrics.

3M’s Historical Odds Of Positive Post-Earnings Return

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

1. There are 20 earnings data points recorded over the last five years, with 10 positive and 10 negative one-day (1D) returns observed. In summary, positive 1D returns were seen about 50% of the time.
2. Notably, this percentage increases to 58% if we consider data for the last 3 years instead of 5.
3. Median of the 10 positive returns = 4.8%, and median of the 10 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.

Investing in a single stock without comprehensive analysis can be risky. Consider the Trefis Reinforced Value (RV) Portfolio, which has outperformed its all-cap stocks benchmark (combination of the S&P 500, S&P mid-cap, and Russell 2000 benchmark indices) to produce strong returns for investors. Why is that? The quarterly rebalanced mix of large-, mid-, and small-cap RV Portfolio stocks provided a responsive way to make the most of upbeat market conditions while limiting losses when markets head south, as detailed in RV Portfolio performance metrics.
