My concern with this one - is the possible hidden risk of "implicit timing" in the calendar switch.

2 of the 3 sizeable bears in post 2009 era ended in Dec - ie 2018 and 2022 - thus significantly aiding the rebalance.
Similarly 2 great bulls ended early ie Feb 2020 ( COVID) and Jan 2022 ( Rate fear) - allowing a booking of TQQQ profits.


A much more robust view would be from GTR1 - which tests impact of Starts - but here it should be testing by moving the rebalance dates by 1 Qtrs say
ie Jan 1st, April 1st, July 1st, Oct 1st - and see if it holds.
