Underlying Asset Performance: WTRE.XETRA tracks the Solactive Global Rare Earths Index. The performance of the rare earth mining companies within that index directly impacts the ETF's price.

Supply and Demand: General market forces of supply and demand influence the ETF's price. Higher demand pushes prices up, while increased selling pressure lowers them.

Geopolitical Risks: Rare earth elements are strategically important. Political instability or trade disputes involving major producing countries affects prices.

Changes in Index Composition: Modifications to the Solactive Global Rare Earths Index, such as the addition or removal of constituents, will influence the ETF's holdings and thus its price.
