CSGP’s Earnings Track Record: Beats, Then Selling

CoStar Group (CSGP) has beaten earnings estimates in all of the last eight reported quarters, a 100% beat rate, with an average earnings surprise of 22.9%. The beats are not marginal. In the last four prints the company delivered actual EPS of $0.32 against a $0.2858 estimate on 2026-07-28 (12% surprise); $0.23 against $0.1742 on 2026-04-28 (32% surprise); $0.31 against $0.273 on 2026-02-24 (13.6% surprise); and $0.23 against $0.1821 on 2025-10-28 (26.3% surprise). That consistency means the headline number has historically landed above the market's real expectation.

Yet the price reaction has repeatedly moved in the opposite direction. The average 5-day price move in the five trading days after earnings across those eight quarters is -6.19%, classified as a down drift. In the last four reports the five-day performance was 0% after the July 2026 print, -2.95% after April 2026, -4.82% after February 2026, and -10.79% after October 2025. The next-day declines were -1.65%, -5.06%, -8.89%, and -9.87%, respectively. For traders, this means CSGP has shown a repeatable pattern of reported beats being followed by near-term selling pressure.

Options-Flow Setup for the 2026-10-27 Print

The next scheduled earnings release is 2026-10-27 after the close, with the current consensus EPS estimate at $0.33. As the event approaches, options implied volatility commonly rises and the market prices in both upside and downside event risk. In a name with this drift pattern, the post-earnings implied move can look large relative to the historical average realized move, especially if traders price in another potential beat.

Watch whether order flow favors call buying for continuation or put buying to hedge a decline. At the current snapshot, CSGP trades at $28.76 with an RSI of 46.3 and a 50-day EMA of $30.93. Because price sits below that 50-day EMA and RSI is neutral-to-bearish, pre-earnings options positioning may lean defensive unless CSGP reclaims the $30.93 level before 2026-10-27. The stock is classified in Real Estate/Real Estate - Services, so macro inputs such as commercial real estate data and interest-rate sentiment also feed into options pricing and flow ahead of the report.

What a Disciplined Trader Monitors

Given the -6.19% average five-day post-earnings drift and the repeated beats-followed-by-selling sequence, the historical beat rate is only half the story. Traders watch the unofficial consensus and the direction of estimate revisions into 2026-10-27, because a $0.33 estimate that gets revised higher before the report can compress the surprise even if CSGP again posts above it.

Key levels are the 50-day EMA at $30.93 and the opening price action in the first 30 minutes after the release. The prior four next-day moves were -1.65%, -5.06%, -8.89%, and -9.87%, so a post-gap reversal or a failure to reclaim the pre-earnings closing price can act as a real-time signal. Volume and options-flow confirmation—especially whether put/call skew spikes after the report—can help distinguish a one-day flush from a sustained down drift.
