|Market Vectors Gold Miners ETF|
|The investment seeks to replicate as closely as possible, before fees and expenses, the price and yield performance of the NYSE Arca Gold Miners Index.
The fund normally invests at least 80% of its total assets in common stocks and depositary receipts of companies involved in the gold mining industry. Such companies may include small- and medium-capitalization companies and foreign issuers. The Gold Miners Index is a modified market-capitalization weighted index primarily comprised of publicly traded companies involved in the mining for gold and silver. The fund is non-diversified.|
