Investing with a Barbell
Barbell strategy: a method that consists of taking both a defensive attitude
and an excessively aggressive one at the
same time, by protecting assets from all sources of uncertainty while
allocating a small portion for high-risk strategies
I am trying here to generalize to real life the notion of the “barbell”
strategy I used as a trader, which is as follows. If you know that you are
vulnerable to prediction errors, and if you accept that most “risk measures”
are flawed, because of the Black Swan, then your strategy is to be as
hyper-conservative and hyper-aggressive as you can be instead of being mildly
aggressive or conservative. Instead of putting your money in “medium risk”
investments (how do you know it is medium risk? By listening to tenure-seeking
“experts”?), you need to put a portion, say 85 to 90 percent in extremely safe
instruments, like Treasury bills – as safe a class of instruments as you can
manage to find on this planet. The remaining 10 to 15 percent you put in
extremely speculative bets, as leveraged as possible (like options), preferably
venture capital-style portfolios (make sure that you have plenty of these small bets; avoid being blinded by
the vividness of one single Black Swan). That way you do not depend on errors
of risk management; no Black Swan can hurt you at all, beyond your “floor”, the
nest egg that you have in maximally safe investments. Or, equivalently, you can
have a speculative portfolio and insure it (if possible) against losses of more
than, say, 15 percent. You are “clipping” your incomputable risk, the one that
is harmful to you. Instead of having medium risk, you have high risk on one
side and no risk on the other. The average will medium risk but constitutes a
positive exposure to the Black Swan. More technically, this can be called a
“convex” combination…For your exposure to the positive Black Swan, you do not
need to have any precise understanding of the structure of uncertainty.

Brilliant
strategy really but of course there is nothing to stop us from
seasoning this to our own taste. In my own investment portfolio I hold
heavy positions in all four of Brookfield Management's Limited
Partnerships...BIP.UN, BEP.UN, BPY.UN and BBU.UN. These holdings
represent a huge (relative to the size of my portfolio) investment in
income producing hard assets. Conversely I hold investments in OTEX,
DSG, AIF, MAXR, BYL, GUD and RX. The stocks of these companies largely
deal with intangible assets. So there is a dichotomy here, a sort of
barbell if you will.
I think there could be many
variations on the "barbell" theme. One could employ investing in ETF's
as an example of setting up his own personal version of the barbell
approach. An investor is only limited to his imagination. Taleb use to
trade options for a living and employed this technique in his trading,
pretty sharp guy this Nassim Nicholas Taleb.
I find
this a highly original and different alternative to the conventional
approach to portfilio management which of course resides in the domain
of the "institutional imperative" where creative thought is suppressed
so as to preserve the status quo of fitting in with the establishment
and not clashing with the drapes.
