Lets say the short interest rate is 6% each while a lot of 3x etf rate is over 10%, your Portfolio2 annual cost is 18%. Portfolio1, 3 doesnt need to rebalance, so Portfolio2 would be a lot of ask/bid cost for each re balance in and out. So together is like 20%. It looks like you need 3 times the money for Portfolio2 to product your result in graph.
Thanks.
I looked up short rates at IB. They are much lower.
So for Portfolio2: It is about (2.09% + 2.16%)*3 (borrow rate+margin rate) =12.75%. If i add transaction cost 2%, total cost will be approximately 15% annually.
I figured out to add an additional cost in portfoliovisualizer (Basically add cost of advisor fee). Using 15% annual cost, final balance is $123,303. So it is certainly much better than straightup UPRO, but not better than using future
