We often discuss how to use options trading strategies for hedging portfolios and investing in general. Yesterday, we argued that the current low-volatility environment can pose significant risks
to portfolios through increased position size and leverage. So a
natural question arises: can we still use options to invest in a
low-risk way these days?
Before answering this question, let’s look at another article
published on Bloomberg. Dean Curnutt pointed out the same problem posed
by the low realized volatility, i.e. increased position size through the
use asset allocation models.
Asset prices are full, but negligible volatility encourages
exposure to them without any discomfort. There are losses here and
there, but in general, the daily experience of mild moves is the
relevant, affirming scorecard. Further, low volatility serves
not as just an anxiety-reducing palliative, but also is a mathematical
driver of trade sizing codified into hundreds of billions of risk
managed investment strategies. Volatility control products, for
example, gear up or down exposure to the equity market based on the
level of realized volatility versus a preset target. Because of the
diminutive daily moves in equity indices, products such as volatility
control move toward their maximum long exposure. The sell signal for
volatility control and other strategies like it is unambiguous: a rise
in realized volatility. Stewards of capital should be actively
considering the potential knock-on effects that result from contractual
deleveraging triggered by the inevitable volatility spike. Read more
Therefore, in this low volatility market, short premium strategy can
be dangerous. Recently, Man group CIO Sandy Rattray gave a warning
“Historically there seems to be a new group of people each time
that underappreciates the very significant risks of being short
volatility and wants to learn this expensive lesson.”
That “expensive lesson” can occur during a volatility spike when
an overleveraged portfolio learns how sharp the two-sided sword of
volatility can become. The strategy is known for generating consistent
and sometimes oversized returns regardless of minor market gyrations. On
a correlation matrix, the strategy appears noncorrelated, until
that faithful moment of crisis hits, then an improperly leveraged
portfolio with insufficient risk controls can get wiped out – and using
margin, a net worth can go negative.
While some in the derivatives space have dismissed short volatility as a viable strategy, Rattray notes that, in proper doses and with risk management, the strategy [has] a place.
“Shorting volatility should only comprise a relatively small part of a
portfolio, and should have a clear risk-management process around it. If
you don’t follow those two rules, then you could potentially end up in
significant trouble,” he said. “There is no question that these
short-vol strategies can pose significant risk to individual investors
pursuing them if they are not managed appropriately.” Read more
So the last paragraph answers our question. We’d suggest reading it multiple times.
