🔴
Bearish
Positives: RSI 56 — healthy momentum range. Concerns: trading below the 200-day MA (long-term downtrend); below the 50-day MA (medium-term momentum negative); 50-day MA is falling (-1.89% over 10 days); weak 1-year return of -21.6%; 3-month momentum negative (-9.5%). Currently 34.1% off its 52-week high. Score: -5/7.
TTEK is trading below its 200-day MA ($33.40) — a key warning sign the longer-term trend is under pressure. An RSI of 56.0 sits in the neutral zone — momentum is neither stretched nor exhausted. The 1-year return of -21.6% compares to +22.9% for SPY (trailed the market by 44.4%). The current 34.1% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
