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.
Concerns: trading below the 200-day MA (long-term downtrend); below the 50-day MA (medium-term momentum negative); 50-day MA is falling (-2.60% over 10 days); RSI 22 — oversold; weak 1-year return of -61.1%; 3-month momentum negative (-15.0%). Currently 75.2% off its 52-week high. Score: -7/7.
QSI is trading below its 200-day MA ($1.17) — a key warning sign the longer-term trend is under pressure. An RSI of 22.1 has dropped into oversold territory, which has historically preceded short-term bounces. The 1-year return of -61.1% compares to +16.5% for SPY (trailed the market by 77.6%). The current 75.2% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
