Can I buy Nasdaq Composite?

I'm curious about the possibility of purchasing the Nasdaq Composite. Is it even possible to buy this index directly, or do I have to invest in individual stocks that are a part of it? Are there any exchange-traded funds (ETFs) or other investment vehicles that track the performance of the Nasdaq Composite? Additionally, could you elaborate on the potential risks and benefits of investing in the Nasdaq Composite, and what factors I should consider before making such an investment?
