Deconstructing MPC's Earnings Track Record

Over the last eight reported quarters, Marathon Petroleum (MPC) has delivered beats seven times, for an 88% beat rate. The headline figure is even more dramatic: the average earnings surprise across those quarters is 471.5%. A superficial read would suggest the stock should be a reliable post-earnings winner, yet the price action tells a more complicated story. The average 5-day price move in the five trading days after earnings is only 2.16%, classified as an "up" drift.

More importantly, that small positive drift masks a pattern where beats do not automatically translate into a rally. On 2026-05-05, MPC reported actual EPS of $1.65 versus an estimate of $0.739—a 123.3% surprise—and it still sold off 5.65% the next day and 3.27% over the following five sessions. Likewise, on 2025-08-05, a 22.2% beat ($3.96 actual vs. $3.24 estimate) produced a 3.84% next-day drop and a 5.81% decline over five days. Conversely, the 2025-11-04 miss ($3.01 actual vs. $3.15 estimate, a 4.4% negative surprise) saw the stock rise 1.31% the next day and climb 8.9% over the next five trading days. These numbers illustrate that the market's real expectation is not always captured by the published consensus.

The 2026-08-04 Earnings Calendar and Options-Flow Context

MPC's next scheduled report is on 2026-08-04 before the open, with a consensus EPS estimate of $14.27. The stock closed at $311.55, with a 50-day EMA of $281.17 and an RSI of 64.0. With the event less than a day away, options markets are pricing a specific implied move that may exceed the historical 2.16% average drift. In other words, the options-flow environment around this report likely reflects a premium for unknown outcomes, not just the published $14.27 figure.

That creates a classic post-earnings volatility-setup question: does the implied move priced into near-the-money straddles or strangles look too large relative to the historical average 5-day realized move of 2.16%? Given MPC's history of large EPS surprises but smaller-than-expected price follow-through, the options market may be embedding expectations that are not directly tied to headline beats or misses. Traders also need to watch whether option skew is tilted toward calls or puts, because that positioning can exaggerate or dampen the actual price reaction after the 2026-08-04 numbers are released.

What a Disciplined Trader Monitors

For the upcoming report, a disciplined framework starts with comparing the actual EPS to the $14.27 consensus—but then moves immediately to how the stock trades relative to pre-event technical levels. The 50-day EMA at $281.17 is well below the current $311.55 price, and the RSI at 64.0 suggests the stock is not deeply overbought but is also not cheap on a short-term basis. The next-day move matters, but the five-day drift matters more, because the historical pattern shows that direction often reverses after the initial reaction.

Traders should also track where post-earnings volume and implied-volatility compression settle. A large beat can still coincide with a sell-the-news unwind if the market's real expectation had already moved well past consensus. Conversely, a miss can recover if refining-margin commentary resets forward estimates. The 2025-11-04 miss and subsequent 8.9% five-day gain is a textbook example. Once the numbers are out, the trade becomes less about the EPS print and more about whether the price reaction validates or contradicts the pre-event positioning.
