QSI is trading below its 200-day MA ($1.24) — a key warning sign the longer-term trend is under pressure. An RSI of 59.6 sits in the neutral zone — momentum is neither stretched nor exhausted. The 1-year return of -34.4% compares to +24.4% for SPY (trailed the market by 58.8%). The current 66.1% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
