First, an update on the the Millman Healthcare Inflation Guard ETF (MHIG) and the Millman Healthcare Inflation Plus ETF (MHIP). We tried to look at these a couple of times and the most recent time I got information from Copilot that was off by a little bit.
Here is the "risk" allocation for MHIG
And here it is for MHIP
As I look at the holdings for each fund, they don't quite seem to correspond to the respective "risk" allocations. If they really mean risk allocation then there is probably a risk parity sort of dynamic to the funds, not that they seek equal risk weightings but that they target risk weightings from each segment. Both slides say long term treasuries but it looks like the furthest they go out is five years. I also didn't see any gold, instead they both have Van Eck Gold Miners (GDX), far less than 30%. GDX is much more volatile than GLD so using GDX appears to be a sort of leverage, they'd need to own a lot more GLD to equal the volatility of GDX. Note that volatility and risk are not the same thing but this does create some context for using a smaller weighting to GDX versus putting 30% in GLD.
The vast majority of the equity is in healthcare stocks with both MHIG and MHIP having small weightings to the S&P 500. For this post, we'll treat the risk allocation as the asset allocation. To backtest we'll use XLV for healthcare equities, GLD for gold and SHY for short term treasuries. Using a five year proxy for "long term" treasuries seems off to me so we'll use TLH which is 10-20 years.
The results are good. The drawdowns have generally been less than VBAIX or the Permanent Portfolio Fund (PRPFX). Part of the long term success stems from XLV going down much less than the S&P 500 in 2008. There's a low or minimum volatility effect that the backtest benefitted from. Low/min vol is just a factor so sometimes it helps performance and sometimes it doesn't. If we were to shorten the back test to just 15 years then it is almost a dead heat between the MHIP replication and VBAIX.
The idea of healthcare companies as a proxy for broad based equity exposure is not something we've looked at before.
The low volatility idea doesn't quite stick in this table but the standard deviation of XLV has been 12.13 versus 9.47 for USMV and 13.92 for SPY.
I didn't include it in the back test but comparing the MHIG replication to AGG, for the entire period MHIP compounded at 7.00% versus 3.03% for AGG and for the last 15 years MHIG compounded at 5.86% versus 2.2% for for AGG. That may not be the best comparison though.
Resolve Asset Management has a paper up about how to diversify within trend following that concludes three distinct management styles is the way to go. Not just three different funds but funds that come at trend differently; different risk weighting or different signal speeds and maybe replication versus full implementation.
Copilot read the paper and it concluded that the best three funds to capture the intended effect was AQMIX, DBMF and KMLM. I was not wowed by the paper so I asked Copilot "Is the paper compelling or is the conclusion just so-so?" Copilot said it is moderately compelling but not a breakthrough.
I am all in on having some exposure to managed futures but we've talked regularly about it being a difficult hold.
Over the last year, most funds have ripped higher but the chart makes the point about considering more than one fund. The worst performer in the last year, the pink line, has had plenty of instances where it was one of the best performers. Clients own one dedicated managed futures fund and get more exposure through BLNDX.
