Should You Invest in Quantum Computing Stocks Now?

Quantum computing is still in its early commercial phase, and the majority of companies in this space are not yet generating consistent profits directly from their quantum initiatives. However, institutional investment is rising, and governments are backing national quantum strategies.

Key Considerations for Investors:

• Long-term horizon: These stocks are suited for long-term growth, not short-term gains.
• Diversification: Blend pure-plays like IonQ with tech giants like Microsoft or Alphabet.
• Volatility: Pure quantum stocks can swing 10–20% on earnings or product news.
