Here’s whether CoStar Group Inc (CSGP) is worth buying in 2026 —
based on weekly-updated price trend, RSI momentum, and return vs.
the S&P 500. Our current read: Caution.
🟡
Caution
Positives: above the 50-day MA (medium-term momentum positive); RSI 64 — healthy momentum range. Concerns: trading below the 200-day MA (long-term downtrend); 50-day MA is falling (-1.55% over 10 days); weak 1-year return of -63.2%. Currently 64.8% off its 52-week high. Score: -2/7.
CSGP is trading below its 200-day MA ($46.53) — a key warning sign the longer-term trend is under pressure. An RSI of 64.2 sits in the neutral zone — momentum is neither stretched nor exhausted. The 1-year return of -63.2% compares to +20.4% for SPY (trailed the market by 83.6%). The current 64.8% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
