|Market Vectors Trs-Hdgd Hi-Yld Bd ETF|
|The investment seeks to replicate as closely as possible, before fees and expenses, the price and yield performance of the Market Vectors® US Treasury-Hedged High Yield Bond Index (the "Treasury-Hedged High Yield Bond Index").
The fund normally invests at least 80% of its total assets in securities that comprise the fund's benchmark index. The Treasury-Hedged High Yield Bond Index was designed to provide exposure to below investment grade corporate bonds, denominated in U.S. dollars, and, through the use of U.S. Treasury notes, to hedge against rising interest rates. The fund is non-diversified.|
