In my opinion, we should not start with 1955. If I were in that time, I knew the inflation was high and there was no sign that the FED interest rate is going to be lower at that time, then there is no negative relation between stock and LTT, and I would not invest in this strategy. I would also quit this strategy once the inflation seems to be higher and FED can't control it any more.MotoTrojan wrote: ↑Mon Aug 12, 2019 3:06 pmWhat about 1955-1982, or 1955-2019.physixfan wrote: ↑Mon Aug 12, 2019 2:58 pm I really don't get the reason why OP changed the strategy from risk parity 40/60 to 55/45 which seems random to me.

Remember the context of the discussion, which is that you can't get the same return going from 2% to 0% (or somewhat lower) that you get in going from 15% to 2%. That applies whether you're looking at 1X or 3X.
Backing up further, I'm simply providing the bond math for those who have cautioned against relying too much on the returns from a backtest period when long-term Treasuries (not leveraged, not even extended duration) returned 2,400%. I'm not saying that you can't make a lot of money on long-term Treasuries, and of course even more on a 3X LTT fund with a duration of about 54 years, if rates drop from 2% to 0%.

It can still be risk parity if OP believes that the ex post risk for TMF is understating the actual true risk that TMF is exposed to to.

Risk parity (or risk premia parity) is an approach to investment portfolio management which focuses on allocation of risk, usually defined as volatility, rather than allocation of capital. The risk parity approach asserts that when asset allocations are adjusted (leveraged or deleveraged) to the same risk level, the risk parity portfolio can achieve a higher Sharpe ratio and can be more resistant to market downturns than the traditional portfolio.
Some AA ratios with CAGRS were presented and a ratio was selected. If this was about risk parity, shouldn't numbers on volatility and sharp ratios be presented and a selection made from those?
An extra 10-15% drawdown in a major equity crisis isn't fun, but the original 40/60 has a much worse drawdown since 1955 due to the rising rate environment, so in that aspect the allocations shift actually reduces drawdown potential.ocrtech wrote: ↑Mon Aug 12, 2019 5:09 pm

I think it's reasonable to argue that our simulated dataset may be giving a false indication of risk parity, given that LTT yields look fairly different today than from the majority of the backtesting on which that risk parity was calculated.

Yeah, anyone with a heavy position in long bonds should be open to taking a position in something else, like gold, that might do well if both bonds and stocks do not.
This seems counterintuitive- more exposure to UPRO would suggest lower returns in an equity bear market.

Changing AA which increases the probable loss in a bear market, as this does, seems to be the opposite of risk parity. Seems folks now looking at this as return/risk just like folks would pick a 60stock/40 bond AA instead of a risk parity 10stock/90 bond AA, which is fine with me.
One should take only so much risk (that may be a bit more than 60/40... but definitely less than 120/180 or 165/135 with 3x leverage...) with money you want to be there later for necessities.
I’m saying in an equity bear more UPRO exposure is worse but that there can also be a bond bear and in that case more UPRO can help.Meaty wrote: ↑Mon Aug 12, 2019 7:31 pmThis seems counterintuitive- more exposure to UPRO would suggest lower returns in an equity bear market.

I'm going in with a pretty small portion of my Roth assets (~$35k). It's equivalent to about 1/4 of my annual stock grant from work.

EDV (extended duration treasuries) tends to outperform TYD (3x intermediate) slightly when yields are flat or increasing, apparently due to the Cost Matters Hypothesis (lower expense ratio). TYD might have a small edge when yields are falling (but not much). EDV has a much smaller bid-ask spread (lower trading costs) and lower tracking error... which seems to tip the scales definitively over to EDV (any time a Vanguard ETF can play a similar role as a Direxion ETF, prefer Vanguard IMO).

Ah, OK. That makes more sense. However, you quote CAGR in these 3 examples, and nothing about volatility or risk parity. I don't see anything in these numbers where 45/55 has a logic to it. Maybe it seems like over-fitting?
Might be time to take some winnings off the table (i.e., cut down on margin)? If this says what it looks like it says, your ETFs are at IB and they can start selling your assets at any time if your equity in the account (the part you own - beyond the money loaned to you by IB) doesn't meet their minimum requirements. Even under relatively favorable historical conditions for a bear market, like 2000-2003 and 2008, there were some drawdowns for a UPRO/TMF combo that could trigger margin calls.privatefarmer wrote: ↑Mon Aug 12, 2019 10:54 pm 4.5x total leverage using a combo of LETFs and margin loan from IB
Correct. Furthermore, my backtesting suggests that there is no significant difference between how you get your weighted-duration exposure, so the real question is what weighted-duration you want. Using TYD at the same allocation as you would've used TMF will simply reduce your duration exposure; yes it will cause less of a drag/loss during rising rate periods, but it also will have less protection during an equity crisis, and less rebalancing bonus when correlations are negative; not that it is a bad move, just a bad way to implement it. There may be some merit to going ultra-short with mega leverage (like the individuals using 2-year treasury futures) but my backtesting only looked at ETFs that may be used in a manner similar to the OG strategy.MoneyMarathon wrote: ↑Mon Aug 12, 2019 10:45 pmEDV (extended duration treasuries) tends to outperform TYD (3x intermediate) slightly when yields are flat or increasing, apparently due to the Cost Matters Hypothesis (lower expense ratio).
