They are not UCITS compliant and cannot be traded as an ETF in Europe, but can be traded as CFDs instead. For this portfolio currenty people are turning to EToro because they provide them, please add them as well.
There is no 3x 20Y Treasuries available in Europe so the best we can do is simulate it with 1x and 5x in 50% ratios, e.g. a pie of 50% DTLA + 50% TLT5.
Thanks for the heads-up! Do you know if there are any studies on the slippage effect of combining two instruments with low/high leverage instead of having one with “medium” leverage?
