Specific Stock News: News affecting major holdings (earnings reports, product launches, regulatory changes) can move the ETF price.

Innovation Sentiment: Investor perception of innovative technologies and companies influences demand for ARK ETFs.

Interest Rate Changes: Rising interest rates can negatively impact growth stocks, which are often heavily represented in ARK ETFs.
