Quantum-Si Incorporated Class A Common Stock
Here’s whether Quantum-Si Incorporated Class A Common Stock (QSI) is worth buying in 2026 — based on weekly-updated price trend, RSI momentum, and return vs. the S&P 500. Our current read: Bearish.
Positives: RSI 45 — 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 (-7.10% over 10 days); weak 1-year return of -34.0%; 3-month momentum negative (-16.9%). Currently 76.1% off its 52-week high. Score: -5/7.
QSI is trading below its 200-day MA ($1.07) — a key warning sign the longer-term trend is under pressure. An RSI of 44.5 sits in the neutral zone — momentum is neither stretched nor exhausted. The 1-year return of -34.0% compares to +20.4% for SPY (trailed the market by 54.3%). The current 76.1% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
