@DonkeyInvestor I would describe it as a booster for your equity portfolio. I think that's what you had in mind with your tech ETF. The 3xGTAA is much broader in scope. The two together don't hurt each other and complement each other very well (in my eyes).
@DonkeyInvestor I have both. <security:n/a:DE000LS9VVV3> US Momentum Leaders is a concentrated equity momentum model. I've added it to my trading portfolio because I'm curious to see how it performs beyond the backtests. If it performs as expected, I will gradually add to it more significantly.
