CTAP
Simplify US Equity PLUS Managed Futures Strategy ETF
stock NYSE ETF

Baseline: 100% equities with slight home country bias
Leverage pilled: Use leverage. One simple path is UPRO + VXUS, like 40/60 UPRO/VXUS for 120/60 notional exposure to SPY/VXUS
Alternative: Use leaps on an index Global ETF like ACWI. Deep ITM ACWI leaps can give cheap implied borrow and adjustable leverage control. Depending on bid/ask and strike price and the cost of underlying, you can gauge your initial leverage to what you like, whether its 1.2x or 1.5x or 2x, etc
Id stop here for most risk-on investors^
For more esoteric blind mean-variance optimization:
Return stacking: learn more before you buy. Easiest one to advise is adding bonds or TIPS like EDV or LTPZ. Bonds are uncorrelated to stocks and go up in value during regular recessions to offset equity drawdowns. Other uncorrelated diversifiers are managed futures, or static positions in something like gold (us GDE for 90/90 spy/gold exposure tax efficiently and low fee). RSST is SPY+MF trend algo, CTAP is SPY+CTA (multistrat managed futures with trend, carry, intermarket signals, etc).
Black box: AQR offers mutual funds with market neutral long short factor exposures. These can provide global diversification and market beta diversification, like Qleix, which longs things like value, profitability, and momentum and shorts stocks with negative exposure to those factors.
