Some Saturday musings on turnkey return stacking / portable alpha solutions...
Consider two fund choices: 100% S&P 500 100% Managed Futures or 100% US Bonds 100% Managed Futures
At the portfolio level, both allow you to do the same thing: stack managed futures.
But there are some very important trade-offs.
Let's assume that both implement their beta with 75% cash securities 25% futures.
Right now, the financing in S&P 500 futures is approximately SOFR 88bp while in US Treasuries it is approximately SOFR. That means implementing the structure on top of equity beta has an invisible 22bp drag (88bp x 25%).
In fact, S&P 500 futures are almost always more expensive than Treasury futures and have traded substantially over the SOFR 30-50bp historical average for the last several years.
Furthermore, if you ask people outright which structure is "riskier" (e.g. which one is more likely to face a substantial margin call), almost everyone will say the equity plus managed futures approach.
And yet equity plus managed futures seems to absolute dominate bonds plus managed futures in sales.
Why?
I'd argue it's all about the perceived line item risk.
Equities are already risky... so what if we add something else on top? And when you combine stocks managed futures, neither dominates the return.
Bonds on the other hand are supposed to be safe and steady. Adding managed futures on top adds substantial volatility. Plus the managed futures dominate the variance, making the alternative return really stand out.
That line-item risk has an increasingly costly trade-off though (especially if you're implementing the beta only with futures...)
