I’m just curious: do you know how they claim to produce exactly 2 * index results? I don’t think this is mathematically possible. If you naively buy the SPY with 50% margin, your return will be (2*SPY – margin interest).
They probably use some option strategies, but no option strategy that I can think of is guaranteed to produce a 2 * index return. For example, selling puts at high strike prices at 2 to 1 leverage returns close to 2 * index most of the time; but if the market goes up sharply they’re left behind.
