The Direxion Daily FTSE China Bull 3X Shares (YINN) primarily achieves its leveraged exposure through derivative swaps and heavy weightings in major foundational assets, most notably the iShares China Large-Cap ETF (which accounts for over 50 percent of its structural allocation), alongside substantial institutional cash equivalents and treasury instruments like the Goldman Sachs Financial Square Treasury Instruments Fund and BNY Mellon government cash management accounts used to collateralize its daily 3X leverage swap agreements.
