Lesley,
Please find attached the Daily Portfolio Report for 5/9. Also, I didn't hear from Jeffrey on Friday, or I
could have been out of cell service. I'm now back, so anytime he's available let me know to finalize basic
commercial terms for IMA per Darren. Thanks!
- Daily Commentary -
There has been considerable discussion recently on how 'Risk-Parity' strategies have performed poorly over the
past 18-months. While we feel most of the discussion is a classic example of most people being unable to
"separate the signal from the noise," there is some truth to the issue vexing these funds. For full disclosure, we
don't know the intricacies of the respective models, but can make some deductions. To be clear, we think risk-
parity makes more sense than most, but with one underling assumption that could potentially create a structural
issue with the methodology.
Specifically, the reliance on long term stable correlations between indicators, which are generally econometric
based. While we assume there are many more than any two variables driving their respective models, it is
evident that the relationship between 10-year break even rates and equity market portfolio weighting has
broken down, recently. Recently, being the operative word, as it's entirely possible these correlations revert
back to historical values. But, what happens if they don't? Maybe it's demographic shifts that have occurred in
the US? Maybe it's the lack of any differentiating technology that fundamentally alters, at the same rate
previously, the speed at which we can complete tasks that encompass most of our day or in our own personal
mobility?
We don't know, but our point, is that relying on these types of correlations on the foundation has it's own risk.
We think our approach of relying on price and volatility mitigates a potential structural breakdown in a similar
fashion. By treating all positions in isolation, if we receive a trade signal we act on it, independent of the
balance of the system. This has it's own risk as well. The trade off we believe is that, although we receive
relatively infrequent trade signals (less than 10 in SPX since 1995), we assume the risk-parity funds receive
even fewer. As such, our win ratio will be less, but we think the trade off is warranted. There's nothing more
disconcerting, when a low-oscillating stable relationship breaks down.

Additional Thoughts
While having some time recently reread the books"Thinking Fast and Slow" and "Rewire Your Brain," a
thought triggered in my mind of why from both a psychological and neuroscience perspective one might be
able to explain why net/gross movement degrades proportional to the square root of the interval of time
forecasted multiplied by average period realized volatility over the interval.
In essence, while it's possible to model this process stochastically, maybe the reason large values of net/gross
movement occurs over short intervals of time is related to (I) people's fast System 1 impulsive responses
(versus the slower but statistically reasoning System 2) to the current moment and (II) how the System 1
response maybe related from a neuroscience perspective to dopamine levels and the interaction between the
prefrontal cortex and the amygdala Wt p://www.dana.org/News/Details.aspx?id=42898). Considering how
something may be different than observed takes cognitive effort, and hence depletion makes the effort more
difficult. Not dissimilar from how in ant colonies al tp://nautil.us/issue/12/feedback/ants-swarm-like-brains-
think) positive feedback provides short term productivity but more instability, but negative feedback provides
long term stability to the system.
Wouldn't it be fun for a Bloomberg Terminal to have a built in PET scanner to measure the current activity
levels of the prefrontal cortex and the amygdala? May create the ability to construct a great mean reversion
strategy as net/gross movement is high over short intervals of time, as PMs dopamine levels decrease to
minimal levels.

Michael J. Fowler
