🔴
Bearish
Positives: RSI 45 — healthy momentum range. Concerns: trading below the 200-day MA (long-term downtrend); below the 50-day MA (medium-term momentum negative); 50-day MA is falling (-3.47% over 10 days); weak 1-year return of -70.2%; 3-month momentum negative (-24.1%). Currently 71.6% off its 52-week high. Score: -5/7.
CSGP is trading below its 200-day MA ($49.99) — a key warning sign the longer-term trend is under pressure. An RSI of 45.1 sits in the neutral zone — momentum is neither stretched nor exhausted. The 1-year return of -70.3% compares to +16.5% for SPY (trailed the market by 86.7%). The current 71.6% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
