Costar Group Stock Forecast

Sell candidate since Oct 29, 2025 Loss -4.98%

The CoStar Group stock price fell by -1.54% on the last day (Monday, 17th Nov 2025) from $68.05 to $67.00. It has now fallen 3 days in a row. During the last trading day the stock fluctuated 3.54% from a day low at $66.63 to a day high of $68.99. The price has been going up and down for this period, and there has been a -3.43% loss for the last 2 weeks. Volume fell on the last day along with the stock, which is actually a good sign as volume should follow the stock. On the last day, the trading volume fell by -111 thousand shares and in total, 3 million shares were bought and sold for approximately $224.12 million.

The stock lies in the lower of a wide and falling trend in the short term, and this may normally pose a very good buying opportunity. If the lower trend floor at $65.63 is broken, it will firstly indicate a stronger fall rate. Given the current short-term trend, the stock is expected to fall -25.96% during the next 3 months and, with a 90% probability hold a price between $48.59 and $53.79 at the end of this 3-month period. Do note, that if the stock price manages to stay at current levels or higher, our prediction target will start to change positively over the next few days as the conditions for the current predictions will be broken.

CSGP Signals & Forecast

There are few to no technical positive signals at the moment. The CoStar Group stock holds sell signals from both short and long-term Moving Averages giving a more negative forecast for the stock. Also, there is a general sell signal from the relation between the two signals where the long-term average is above the short-term average. On corrections up, there will be some resistance from the lines at $67.97 and $74.50. A break-up above any of these levels will issue buy signals. A sell signal was issued from a pivot top point on Tuesday, October 28, 2025, and so far it has fallen -14.36%. Further fall is indicated until a new bottom pivot has been found. Furthermore, there is currently a sell signal from the 3 month Moving Average Convergence Divergence (MACD). Volume fell together with the price during the last trading day and this reduces the overall risk as volume should follow the price movements.

Support, Risk & Stop-loss for CoStar Group stock

There is no support from accumulated volume below today's level and given the right condition the stock may perform very badly in the next couple of days.

This stock has average movements during the day and with good trading volume, the risk is considered to be medium. During the last day, the stock moved $2.36 between high and low, or 3.54%. For the last week, the stock has had daily average volatility of 2.38%.

CoStar Group is oversold on RSI14 (19). Some stock may drop long and hard while being oversold on RSI before turning, which increases the general risk.

Our recommended stop-loss: We hold a negative evaluation for this stock. No stop-loss is set.

Trading Expectations (CSGP) For The Upcoming Trading Day Of Tuesday 18th

For the upcoming trading day on Tuesday, 18th we expect CoStar Group to open at $67.54, and during the day (based on 14 day Average True Range), to move between $65.92 and $68.08, which gives a possible trading interval of +/-$2.17 (+/-3.29%) up or down from last closing price. If CoStar Group takes out the full calculated possible swing range there will be an estimated 3.29% move between the lowest and the highest trading price during the day.

With no support below and resistance from accumulated volume @ $68.81, some $1.81 (2.70%) from the current price of $67.00, our system finds the risk reward not very attractive.

Is CoStar Group stock A Buy?

CoStar Group holds several negative signals and is within a wide and falling trend, so we believe it will still perform weakly in the next couple of days or weeks. We therefore hold a negative evaluation of this stock.
