RKLB is holding above its long-term 200-day MA ($78.39) but has slipped below the 50-day MA ($85.54), pointing to short-term weakness in an otherwise intact trend. An RSI of 67.6 sits in the neutral zone — momentum is neither stretched nor exhausted. The 1-year return of +87.5% compares to +20.4% for SPY (beat the market by 67.1%). The current 46.9% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
