Williams Companies Reports Soon: How Has The Stock Reacted To Past Earnings

Williams Companies (NYSE:WMB) is scheduled to report its earnings on Monday, November 2, 2026. The company has a market value of about $91.7 billion. Over the last twelve months it generated $12.2 billion in revenue and $4.7 billion in operating profit, with net income of $3.1 billion.

Williams Companies' Historical Odds Of A Positive Post-Earnings Return

Some observations on one-day (1D) post-earnings returns, measured from the last close before each release:

• There are 20 earnings releases in the last five years, with 12 positive and 8 negative one-day (1D) returns. Positive 1D returns were seen 60% of the time.
• Over the last three years that share rises to 67%, across 12 releases.
• The median of the 12 positive 1D returns is 1.9%, and the median of the 8 negative ones is -2.3%.
• The largest one-day reactions were 4.8% and -4.3%.

The table below shows the 1D, 5-day (5D) and 21-day (21D) returns after each release, followed by summary statistics.

Correlation Between 1D, 5D, And 21D Post-Earnings Returns

Another approach is to wait for the initial reaction and ask whether it tends to continue. The table below shows the correlation between the 1D return and the return over the following 5 and 21 trading days, and between the 5D return and the following 21 trading days. A value near 1 means the first move has tended to continue; near -1, to reverse; near 0, no consistent pattern. Over five years, none of these correlations are strong enough to trade on: all are below 0.40 in absolute terms, so the early post-earnings move has not reliably predicted what followed. The 3-year 1D vs next 5D figure of -0.43 hints at a partial reversal, but it rests on only 12 releases.

Do Peers That Report First Offer A Clue?

Kinder Morgan (KMI) usually reports about 14 days before Williams Companies and has already reported this season. Its stock fell 0.7% the day after its October 21 report. The table compares Kinder Morgan's one-day reaction to its own earnings with Williams Companies' one-day reaction to the following report. The correlation is 0.20; the closer to 1, the more the peer's reaction has foreshadowed Williams Companies'. Figures this close to 0 show no consistent link.
