CoStar Group (CSGP): TA Review - Sellers Continue to push. CoStar Group, Inc.NASDAQ:CSGPmindfullylostGood Afternoon, Hope all is well. Here is my TA on CSGP. What I’m Seeing Looking at CoStar Group on the weekly chart, the primary trend is still clearly bearish. Price has fallen from roughly $95–$100 to around $31, remains below a declining weekly trend/average, and has not yet established a confirmed higher-high/higher-low sequence. But I think the character of the decline is beginning to change. The first major breakdown came with a cluster of high-volume selling around $60–$70. That selling produced a substantial move lower. The next leg down toward roughly $40–$45 occurred on noticeably less volume. Then, as price reached the $27–$32 area, volume increased again—but instead of accelerating dramatically lower, price began consolidating. That's the relationship I'm interested in: heavy selling → large downside result → declining participation → final high-volume event → much less downside progress. To me, this could be transitioning from markdown toward seller exhaustion and potential accumulation. The Original High-Volume Cluster Looks Like Distribution The cluster you've marked around approximately $58–$68 looks important. Price was already below the declining weekly trend, several high-volume events appeared, and then support failed. In hindsight, I would interpret that area more as distribution / aggressive liquidation than accumulation. The key evidence is what happened afterward: price accepted materially lower levels. That's very different from what I'm beginning to see near $30. The Volume Progression Is Changing The next stage is particularly interesting. After the initial high-volume breakdown, CSGP continued declining—but volume decreased while price continued lower. That tells me the downtrend remained intact, but participation wasn't necessarily increasing with every new low. Then another high-volume event appeared around the low-$30s. This time, instead of immediately collapsing toward $20, price began moving sideways. That's potentially an effort-versus-result divergence: more selling effort + less bearish price progress. It doesn't prove institutional accumulation. But it tells me supply may be getting absorbed more effectively than it was earlier in the decline. $27–$32 Is My Decision Zone This is now the most important area on the chart for me. Price has spent several months around approximately $27–$32, and the lows have so far stopped extending materially downward. I'd describe this as a potential accumulation zone, rather than confirmed accumulation. What I want to see now is time. If CSGP continues trading around this region while volatility contracts, downside volume fades and momentum improves, the base becomes increasingly credible. The ideal next sequence would be: $27–$30 holds → higher low → $33–$35 reclaimed → expansion. Momentum Turning Positive Matters Your annotation that the daily momentum measure has turned positive for the first time since August 2025 is one of the more constructive signals on the chart. For most of this decline, price and momentum were confirming each other. Now price remains near the lows while momentum is improving. Combined with your observation that the negative directional component has moved beneath the broader directional/trend measure, I'd interpret your indicators as showing that bearish pressure is weakening. But there's an important distinction: sellers losing control ≠ buyers controlling the trend. I think we're potentially seeing the first part. I still need price to prove the second. $33–$35 Is My First Confirmation At approximately $31, CSGP is still inside the bottoming structure. My first meaningful confirmation would be a sustained move through approximately $33–$35. That would push price out of the immediate consolidation and remove a recent swing-high area. Then I want to see what happens on the pullback. My ideal structure would be: $27–$32 base → $35 breakout → controlled pullback → ~$30–$32 holds → higher low → continuation. That would look substantially different from every previous bounce during this decline. $40–$45 Is the Bigger Test Above the initial breakout, $40–$45 becomes much more important. That's where the previous breakdown accelerated and where trapped supply is likely to exist. It's also where the declining weekly trend/average is heading. So I'd roughly map the recovery as: $27–$32 → $33–$35 → $40–$45 → $50+ A reclaim of $40–$45 followed by a higher low would be much stronger evidence that I'm dealing with a genuine weekly reversal rather than simply an oversold bounce. Fundamentals — This Is Where CoStar Gets Interesting Fundamentally, CoStar doesn't look like a company whose core business is collapsing. In Q2 2026, revenue reached $925 million, up 18% year over year. Net income increased to $55 million from $6 million, while adjusted EBITDA rose 116% to $184 million. Adjusted EPS increased 88% to $0.32. Management also described Q2 as its 61st consecutive quarter of double-digit revenue growth. That's an important contrast with the chart: share price ↓ dramatically while revenue and adjusted profitability ↑. That doesn't automatically make the stock undervalued—valuation compression can happen even when a business grows—but it makes this potential technical bottom more interesting to me. Residential Is Starting to Improve One of the biggest questions around CoStar has been how much money it would need to invest in its residential strategy, particularly Homes.com. There are signs that economics are beginning to improve. In Q2, CoStar's residential revenue increased 33% year over year to $444 million, and the residential segment produced positive adjusted EBITDA for the quarter. Earlier this year, management also said it intended to reduce the net investment in Homes.com by more than $300 million in 2026, after roughly $850 million in 2025. That's important to my thesis. If CoStar can continue growing Homes.com while reducing the amount of capital required to support it, the market may begin looking differently at the residential business. But Growth Expectations Have Moderated There is still a legitimate reason for caution. After Q2, management revised full-year 2026 revenue guidance to approximately $3.715–$3.755 billion, or about 15% year-over-year growth at the midpoint. Earlier in 2026, the company had been targeting $3.78–$3.82 billion and roughly 18% growth. So I wouldn't describe everything as improving. The market may be repricing CoStar for a combination of slower-than-previously-expected growth and questions about returns on its large residential investments. The bullish counterargument is profitability: management maintained full-year adjusted EBITDA guidance of $780–$820 million, while Q2 adjusted EBITDA more than doubled year over year. That creates an interesting fundamental tension: growth expectations moderating + profitability improving. The Zonda Acquisition Adds Another Growth Avenue CoStar also recently completed its acquisition of Zonda, expanding further into new-home data, analytics and marketplaces. Management sees potential to combine Zonda's housing and visualization capabilities with Matterport's spatial technology. That's potentially attractive strategically, but acquisitions also create execution risk. So I don't want to assume every new asset automatically creates value. What I want to see over the next several quarters is straightforward: continued revenue growth → residential profitability → stronger consolidated margins → disciplined integration. If those occur while the stock establishes a technical bottom, the fundamental and technical stories begin reinforcing each other. Why This Setup Interests Me This is the disconnect I'm watching. Technically: distribution → high-volume breakdown → lower-volume continuation → high-volume selling near the lows → diminishing downside progress → improving momentum. Fundamentally: 18% Q2 revenue growth → rapidly improving adjusted EBITDA → residential segment reaching positive adjusted EBITDA → continued investment in long-term growth. So I'm not looking at a company where the stock fell because the underlying operation completely collapsed. The question I'm asking is: Has the stock's decline now discounted more deterioration than the operating results are actually showing? Price has to answer that. My Bullish Scenario My preferred sequence would be: $27–$32 base holds → momentum remains positive → $33–$35 reclaimed → controlled retest → higher low → $40–$45. If CSGP subsequently reclaims the declining weekly trend and establishes support above it, I'd become considerably more constructive. From there, $50–$55 would be the next meaningful recovery area, followed eventually by the prior distribution region around $60–$70. I wouldn't jump directly to those targets. I want price to build the structure first. My Bearish Scenario The bearish scenario is straightforward. If CSGP decisively loses approximately $27–$28, especially with renewed volume expansion and deteriorating momentum, I'd assume the base hasn't finished forming. That would weaken the absorption thesis considerably. I'd rather wait for another stabilization area than try to predict where the next low will occur. My Bias I'm cautiously constructive at these levels, but I don't think the reversal is confirmed yet. The combination I like is: high-volume distribution → declining selling participation → another high-volume event near the lows → limited downside follow-through → consolidation → momentum turning positive. And unlike some turnaround charts, the underlying business is still generating double-digit revenue growth while adjusted profitability has improved sharply. So for me: $27–$32 = potential accumulation zone. $33–$35 = first breakout confirmation. $40–$45 = major trend test. $50+ = stronger evidence of a larger recovery. The biggest thing I'm watching now is whether high-volume selling around the lows continues producing less and less downside. If it does—and price begins building higher lows before breaking $35—I think we'll have much stronger evidence that the long markdown is finally transitioning into a bottoming process rather than simply another pause in the decline.
