Is D-Wave Quantum stock a buy right now?

Quantum computing stocks have been incredibly hot in recent months. Some significant technology breakthroughs and bullish comments from tech luminaries including Nvidia CEO Jensen Huang have helped power huge rallies for many players in the space. Expectations that the Federal Reserve will cut interest rates multiple times this year and create a more favorable backdrop for growth stocks have also contributed to valuation rallies in the category.

Advances in quantum computing technologies could power huge leaps forward in artificial intelligence (AI) and other high-value tech categories, and D-Wave seems to be establishing itself as an early front-runner in the space. On the other hand, quantum computing is still a nascent technology -- and charting how progression and competitive dynamics in the space will play out involves a very high degree of guesswork. Risk-tolerant investors seeking exposure to the quantum trend could find D-Wave Quantum stock to be a worthwhile portfolio addition, but the potential for downside volatility in the near term has also increased on the heels of the recent rally.
