Duke Energy Reports Soon: How Has The Stock Reacted To Past Earnings

Duke Energy (NYSE:DUK) is scheduled to report its earnings on Thursday, November 5, 2026. The company has a market value of about $98.6 billion. Over the last twelve months it generated $33.3 billion in revenue and $8.9 billion in operating profit, with net income of $5.2 billion.

The reaction will turn on how the results and guidance land against expectations. Before the release, it helps to know how the stock has behaved after previous reports, and whether an early move has tended to carry on.

How Often Has Duke Energy Stock Risen After Earnings?

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

• There are 19 earnings releases in the last five years, with 8 positive and 11 negative one-day (1D) returns. Positive 1D returns were seen 42% of the time.
• Over the last three years that share rises to 45%, across 11 releases.
• The median of the 8 positive 1D returns is 1.6%, and the median of the 11 negative ones is -1.0%.
• The largest one-day reactions were 2.8% and -4.7%.

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

Do Early Post-Earnings Moves Continue?

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. None of these correlations is strong enough to trade on: all are below 0.40 in absolute terms over five years, so the early post-earnings move has not reliably predicted what followed.

Is There Any Correlation With Peer Earnings?

NextEra Energy (NEE), Dominion Energy (D) and American Electric Power (AEP) usually report about 4 to 14 days before Duke Energy, and have already reported this season. The table compares each peer's one-day reaction to its own earnings with Duke Energy's one-day reaction to the report that followed. The correlations are NEE (0.37), D (0.15), AEP (-0.06); the closer to 1, the more the peer's reaction has foreshadowed Duke Energy's.

An earnings release can move one stock sharply in either direction. A diversified portfolio spreads that risk. The Trefis High Quality (HQ) Portfolio holds about 30 quality businesses, re-balanced with rules, and has a track record of outperforming a benchmark that combines the S&P 500, the S&P MidCap 400, and the Russell 2000.
