CTMX is trading below its 200-day MA ($4.18) — a key warning sign the longer-term trend is under pressure. An RSI of 54.9 sits in the neutral zone — momentum is neither stretched nor exhausted. The 1-year return of +61.6% compares to +20.5% for SPY (beat the market by 41.1%). The current 60.0% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
