Please stay away from leverage equity index funds. https://capitalallocatorspodcast.com/wp-content/uploads/2017... Edit: For more clarity - risk parity can make sense, but I don't think you ever need to use leverage on your equities to get risk parity. The fundamental insight of risk parity investing is that at commonly recommended ratios (50/50, 60/40) the risk (variance) from equities totally dominates the risk from bonds. So the risk parity advice is usually something with a much higher bond mix, but the entire portfolio is leveraged. But DO NOT use levered ETFs that recognize, say, 3x the DAILY movement of the S&P to do this. They don't do what you think. Read that link, or compute the following two scenarios: 1) Market goes up 1.1% on odd days, down 1% on even days. That yields about 9% (200 trading days). But a 3x daily etf product would only get you about 22%, not 27%. 2) Market foes up 1% on odd days, down 1.1% on even. That, sadly, means you lose about 11% on the year. If you use a 3x DAILY etf product, you lose around 75%. |
That issue is addressed in the bogleheads post explicitly ("How much does the leverage cost?" and "Don't you know that leveraged ETFs are only intended to be held for one day?"), basically the ETFs are risk parity adjusted, and the volatility in the ETFs actually what generates the returns. The strategy makes money from volatility, and the 3X leverage is used to add volatility in, exaggerating the returns.
I think you might find the post interesting because it seems like you are interested in investing. What you're saying is again explicitly addressed there, and factored into the calculation. They work an example of that kind of decay, and how it's mitigated. Specifically, it doesn't matter that you have volatility decay in one of the ETFs because they're uncorrelated, and when one goes up the other goes down, canceling out the effect.
Your blanket statement does not apply to this specific strategy. It's not wrong in general, but it's not relevant here.
If you don't want to read the bogleheads write-up it's also addressed on Seeking Alpha [1].

Not if, as you see in the write-up, you pair it with an uncorrelated 3X leveraged asset and rebalance periodically.
The post includes a backtest to 1987.
