Underlying Asset Performance: ROX.XETRA ETF's price heavily relies on the performance of the assets it tracks, be they an index, sector, or commodity.

Market Sentiment: General market optimism or pessimism significantly affects ETF prices. Broad market rallies can lift ETF prices, while downturns can drag them down.

Tracking Error: The difference between the ETF's return and the return of its benchmark index. Greater tracking error can indicate less precise replication of the target index.
