GPC

What GPC's Earnings Track Record Actually Shows

Over the last eight reported quarters, GPC beat the published consensus five times, for a beat rate of 62%. Despite that headline success rate, the average earnings surprise across those quarters is -3.1%, meaning the misses were larger on average than the beats were positive. The average 5-day price move in the five trading days after earnings across those quarters is -1.77%, with GammaQC classifying the post-earnings drift direction as "down."

The four most recent quarters show why the headline beat rate can obscure actual price behavior. On July 21, 2026, GPC reported actual EPS of $2.15 against an estimate of $2.08, a 3.4% positive surprise and a beat, yet the stock rose only 1.05% the next day before extending to an 8.89% gain over the following five days. That is the only one of the last four prints to show a positive five-day reaction. On April 21, 2026, the company beat by 1.1% with actual EPS of $1.77 versus $1.75 estimated, but the stock fell 2.83% the next day and 8.34% over five days. The two misses were punished more severely: February 17, 2026 produced a -14.8% surprise with actual EPS of $1.55 against $1.82 estimated, driving a 3.84% next-day drop and a 5.5% five-day decline. October 21, 2025 miss of -2%, actual EPS $1.98 versus estimate $2.02, led to a 1.23% next-day fall and a 2.12% five-day fall.

Options-Flow Dynamics Around the October Print

GPC is scheduled to report next on October 20, 2026, before the market open, with the published consensus EPS estimate at $2.08. The stock's current price is $127.545, and the technical snapshot shows RSI at 59.7 and 50-day EMA at $117.35, so price is roughly $10.20 above that medium-term smoothing level heading into the report.

For options flow around the next earnings, traders tracking implied volatility typically compare whether the straddle or strangle is pricing a move larger or smaller than what realized post-earnings history would imply. Given the recent mixed reaction—an 8.89% five-day gain after the July 2026 beat but three consecutive five-day declines in the preceding three reports—options positioning may be particularly sensitive to downside gap risk. Market makers usually mark implied volatility higher as October 20 approaches, and any directional order flow that appears before the report can signal whether the market's real expectation leans toward a beat or a miss, separate from the published consensus.

What a Disciplined Trader Watches For

With the five-day post-earnings drift averaging -1.77%, a disciplined trader would not automatically assume the 62% beat rate translates into post-earnings gains. The average earnings surprise is -3.1%, which means the misses have been larger than the beats, and the average post-earnings drift remains negative. That combination suggests monitoring the reaction over the full five-day window rather than judging the trade from the opening gap alone.

Specifically, the trader should compare the October 2026 consensus EPS of $2.08 with the actual print, watch whether the $127.545 price is extended relative to the $117.35 50-day EMA, and mark the post-earnings reaction time stamps from the prior reports. April 21, 2026's -8.34% five-day move and July 21, 2026's +8.89% five-day move define the recent directional extremes. A plan that distinguishes between the overnight gap and the multi-day drift, and uses the prior five-day move distribution as context, is more consistent with this historical record than simply positioning for a beat because the overall beat rate is above 50%.
