ACGL

Historical Beat Rate vs. Actual Price Drift

Arch Capital Group (ACGL) has delivered an immaculate earnings record over the trailing eight quarters, beating the consensus estimate in all eight reports, with an average beat of 13%. At first glance, that 100% beat rate suggests the company routinely clears the bar. Yet the post-earnings price behavior tells a more complicated story. Across those same eight quarters, the average 5-day move following the report has been just 0.74%, classified as an “up” drift. The number is positive, but it is small relative to the size of the beats.

The disconnect shows up clearly in the four most recent reports. On February 9, 2026, ACGL beat the $2.59 estimate with actual EPS of $2.98, a 15.1% surprise, and the stock rose 1.86% the next day and 2.94% over the following five sessions. But on April 28, 2026, the company beat again—EPS of $2.50 versus a $2.48 estimate, a 0.8% surprise—yet the stock fell 4.47% the next day and 3.01% over the next five days. The October 27, 2025 report delivered a 22.6% beat ($2.77 vs. $2.26) and the next-day reaction was still negative at -1.42%, though the five-day drift was essentially flat at +0.07%. The July 29, 2025 print, a 12.2% beat ($2.58 vs. $2.30), produced a -0.59% next-day move but a +2.95% five-day drift. In other words, beats have not reliably translated into directionally consistent follow-through.

Options-Flow Dynamics Around the July 28 Report

With the next scheduled earnings release on July 28, 2026, after the close and the consensus EPS estimate at $2.45, the options market prices in the implied move for the upcoming report. The stock is currently at $101.35, above the 50-day EMA of $96.55, with an RSI of 59.8. Those levels frame how dealers and market makers may hedge gamma and delta around the event.

Because the historical five-day drift is a positive 0.74%, directional positioning can lean toward upside continuation. But the four-quarter record shows realized post-earnings outcomes are mixed; the average next-day move across the four most recent reports is -1.16%. That combination—positive 0.74% average five-day drift, negative -1.16% average next-day move, and individual five-day outcomes of -3.01%, +2.94%, +0.07%, and +2.95%—means options volatility is likely capturing binary event risk along with the post-release trend.

What a Disciplined Trader Watches

A disciplined approach treats the 100% beat rate and 13% average surprise as history, not a forecast for the July 28 report. Heading into the print, traders watch whether ACGL holds the $96.55 50-day EMA and whether implied volatility is elevated relative to the 0.74% average five-day drift. They also compare the $2.45 consensus estimate with the unofficial consensus and management commentary, since the April 28, 2026 and October 27, 2025 reports show that even large beats have been met with immediate selling.

The pattern to monitor is whether the stock reverses the next-day move or follows through. On February 9, 2026, the next-day rally of 1.86% extended into a five-day gain of 2.94%. On April 28, 2026, the next-day drop of 4.47% extended through a five-day decline of 3.01%. The October 27, 2025 and July 29, 2025 prints each saw initial selling followed by flat or recovering five-day performance of +0.07% and +2.95%, respectively. Watching volume on the first post-earnings session and whether the price tests the 50-day EMA helps distinguish whether the market is repricing fundamentals or simply digesting the release.
