CSGP is trading below its 200-day MA ($59.42) — a key warning sign the longer-term trend is under pressure. An RSI of 60.5 sits in the neutral zone — momentum is neither stretched nor exhausted. The 1-year return of -56.7% compares to +24.4% for SPY (trailed the market by 81.0%). The current 65.2% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
