General Dynamics (NYSE: GD) is scheduled to report earnings on Friday, October 30, 2026. The company has a market value of about $93.1 billion. Over the last twelve months, it generated $54.9 billion in revenue and $5.7 billion in operating profit, with net income of $4.5 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.

General Dynamics’ 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:
The table below shows the 1D, 5-day (5D) and 21-day (21D) returns after each release, followed by summary statistics.
Does The First Move Carry On?
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 are 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.
Does A Peer That Reports First Offer A Clue?
RTX usually reports a day or a few days before General Dynamics. It reported this season on October 20, 2026, and its one-day reaction was a 0.6% gain. The table compares RTX’s one-day reaction to its earnings with General Dynamics’ one-day reaction to its subsequent report. It covers the 19 quarters in which RTX reported first; in July 2024 RTX reported a day later. The correlation is -0.06, close to zero, so RTX’s reaction has not foreshadowed General Dynamics’ in either direction.
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, rebalanced 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.
