🔴
Bearish
Positives: strong 1-year return of +88.7%. Concerns: trading below the 200-day MA (long-term downtrend); below the 50-day MA (medium-term momentum negative); 50-day MA is falling (-14.61% over 10 days); 3-month momentum negative (-47.6%). Currently 67.6% off its 52-week high. Score: -4/7.
SES is trading below its 200-day MA ($1.68) — a key warning sign the longer-term trend is under pressure. An RSI of 69.8 sits in the neutral zone — momentum is neither stretched nor exhausted. The 1-year return of +88.7% compares to +35.1% for SPY (beat the market by 53.6%). The current 67.6% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
