VelocityShares' New Volatility ETFs
(Jul 2013)
You've heard it here before: hedging equity exposure with volatility derivatives is very tricky.
While the CBOE Volatility Index (VIX) and the S&P 500 are negatively correlated suggesting a possible hedging opportunity, you cannot invest in the VIX itself, you have to invest in derivatives (futures or options) linked to the VIX. The simple fact is that this indirect exposure to the VIX does not behave like the VIX itself, making it in the end a rather poor hedge to equities .
But issuers of...
Options Strategies Embedded in Exchanged Traded Products
(May 2013)
In theory, exchange traded products (ETPs) can be linked to almost any underlying asset, including derivatives. While many ETPs are linked to portfolios of bonds or stocks, some are linked to portfolios of futures contracts, which we have discussed at length before. Bill Luby at VIX and More has written a couple posts on ETPs that are linked to portfolios of options, which are gaining some traction with investors. As usual, we greatly enjoyed Bill's posts and thought we'd explain some of the...
Persistence and Mean Reversion in VIX Rolling Futures Indexes
(Mar 2013)
In our last post we followed up on Jason Voss's discussion of the Hurst exponent as a measure of persistence or mean reversion in market data. We compared the Hurst exponents of the S&P 500 to that of the VIX index, and found that the S&P 500 is largely a random signal (Hurst exponent near 0.5) but that the VIX exhibits characteristics of a 'switching' or mean reverting signal (a Hurst exponent between 0 and 0.5).
Much has been made of VIX mean reversion in the financial blogosphere. One idea...
Persistence and Mean Reversion in Market Data
(Mar 2013)
Jason Voss at the CFA Institute has recently written a very interesting series of posts on the Hurst exponent, which is "a method for detecting persistence, randomness, or mean reversion in financial markets." The Hurst exponent measures the degree to which a signal depends on previous values--a phenomenon known as autocorrelation--and specifically whether values tend to 'switch' (e.g., high values followed by low values) or 'persist' (e.g., high values followed by other high values). Jason...
Another ETN Halts New Share Redemptions, Creates Premium
(Jul 2012)
In March we reported on TVIX, the leveraged volatility-linked exchange-traded note (ETN) which started trading at a very large premium to indicative value after its issuer halted the creation of new shares. Bloomberg's Matt Robinson is reporting that AMJ, a JPMorgan ETN linked to oil partnerships, has also limited new share creations and is developing a similar premium.
JPMorgan limited new share creations on June 14, and the premium to indicative value (the value of the underlying index) has...
Is There No Tracking Error for ETNs?
(Apr 2012)
Some investors may think that while ETFs are subject to various tracking errors, ETNs are not. The argument goes that index-tracking ETFs often hold part or the entire portfolio underlying their targeted index and are thus subject to imperfect tracking and transaction costs. ETNs, on the other hand, are debt instruments, and have returns guaranteed by their issuers.
It turns out, however, that the daily return of an ETN investment may not necessarily equal the leverage ratio times the daily...
