CTMX is holding above its long-term 200-day MA ($3.74) but has slipped below the 50-day MA ($4.95), pointing to short-term weakness in an otherwise intact trend. An RSI of 59.5 sits in the neutral zone — momentum is neither stretched nor exhausted. The 1-year return of +665.4% compares to +35.1% for SPY (beat the market by 630.4%). The current 41.3% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
