Leveraged Exchange-traded Funds (ETFs) are a subset of common ETFs, aiming to obtain the performance of the underlying benchmark index several times (for example, 2%, 3% or higher). In addition, some ETFs seek not only multiple performance, but also the reverse function of the underlying benchmark index (for example, shorting ETFs). To achieve this goal, these leveraged funds usually include holding derivative products, such as options, futures or swaps, to provide the required leverage and/or reverse results.

according to the extra leverage and risks of these products, the exchange margin rules set a margin rate equivalent to the leverage level (but not exceeding 1% of the ETF value). For example, the basic maintenance margin requirement for long leveraged ETFs is 25%, and that for short leveraged ETFs is 3%. Examples of maintenance margin for leveraged ETFs are as follows:

1. Long ETF has 2% leverage coefficient: 5% (= 2x25%)

2. Short ETF has 3% leverage coefficient: 9% (= 3x). For example, the RegT maintenance margin requirement for non-leveraged, short-selling ETF index options is 1% of the option premium plus 15% of the ETF market value, minus any out-of-price options (at least 1% of the ETF market value in the case of call options and 1% of the option exercise price in the case of put options). However, when the underlying option is a leveraged ETF, the ratio will increase to 15% according to the leverage coefficient of ETF.

in the case of portfolio margin account, the stress test of leveraged ETF positions will be similar to the results of the scanning range with the increase of ETF leverage coefficient. For more detailed information, please see NASD Rule 252 and NYSE Rule 431.
