Corning (NYSE:GLW) is set to report its earnings on Tuesday, July 29, 2025. Analyzing data from the last five years, GLW stock has often shown negative one-day returns after earnings announcements, occurring in 60% of cases. The median one-day decrease was -3.1%, while the largest single-day negative return was -6.9%.
Although the actual earnings results relative to consensus estimates are important, recognizing these historical trends can provide a benefit for traders focused on events. Two primary strategies can be used to take advantage of this information:
Analysts' consensus projection for the forthcoming quarter is earnings of $0.57 per share on revenues of $3.84 billion. This reflects a predicted improvement from the same quarter last year, which had earnings of $0.47 per share on revenues of $3.60 billion.
From a fundamental viewpoint, Corning currently boasts an estimated market capitalization of around $48 billion. In the past twelve months, the company generated $14 billion in revenue. It was operationally profitable, recording $1.3 billion in operating profits and a net income of $454 million.
However, if you are looking for potential upside with less volatility compared to individual stocks, the Trefis High Quality portfolio offers an alternative — having outperformed the S&P 500 and delivered returns exceeding 91% since its inception.

Correlation Among 1D, 5D, and 21D Historical Returns
A relatively less risky approach (though not effective if the correlation is weak) is to examine the correlation between short-term and medium-term returns following earnings, identify a pair with the strongest correlation, and implement the suitable trade. For instance, if 1D and 5D display the highest correlation, a trader can position themselves 'long' for the succeeding 5 days if the 1D post-earnings return is positive. Here is some correlation data based on 5-year and 3-year (more recent) history. Note that the correlation 1D_5D refers to the relationship between 1D post-earnings returns and subsequent 5D returns.
