    "supporting_data": "The WisdomTree Nickel ETC is classified as complex due to several key factors. It uses a synthetic replication method through fully funded swaps to track nickel futures contracts, which introduces counterparty risk and requires understanding of complex mechanisms like contango and backwardation. The product's risk level is rated 6 out of 7, indicating high risk. The ETC is exposed to commodity futures rolling costs and potential tracking errors due to the nature of futures contracts. Additionally, the product's performance is directly tied to the Bloomberg Commodity Nickel Subindex 4W Total Return Index, which itself incorporates complex financial concepts. The presence of swap agreements and the need to understand commodity futures markets make this product suitable only for investors with specific knowledge or experience.",
