How Does VolDex Stack Up to the VIX?
(Nov 2013)
We've talked a lot about the idea of using volatility to hedge equity exposure. The basic finding, from our research work and that of others, is that the CBOE Volatility Index (VIX) hedges the S&P 500 fairly well. Unfortunately, the VIX is not investable, but is a complicated calculation based on a large strip of options contracts -- i.e., contracts of varying moneyness. Proxies for the VIX, such as rolling VIX futures strategies, are much worse hedges and have a number of problems that make...
Illiquid ETFs and SEC Market Maker Incentives
(Sep 2013)
There is now nearly $1.5 trillion invested in exchange-traded products (ETPs) in some 1,400 exchange-traded funds and exchange-traded notes. However, not all of that huge sum is distributed evenly. Some funds, like SPY, have huge assets under management, while many others struggle to top $10 million. Often, issuers will close lightly-traded ETPs (leading to substantial turnover each year), but if they don't, the market price of an ETP can often deviate from the net asset value of its...
Why Do Volatility ETPs Reverse Split?
(Sep 2013)
We still get a lot of questions about VXX, TVIX, and all of the other VIX-related exchange-traded products(ETPs). We've talked before about the persistent loss of value due to negative roll yield, as well as issues surrounding TVIX's suspension of share creations. We've also talked about some of the newer volatility products that attempt to mitigate some of the issues with the older generation of products. We've also analyzed whether VIX-based ETFs could serve as a hedge to equity...
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...
PowerShares to List Actively Managed Downside Hedged S&P ETF
(Dec 2012)
Late last week, Invesco PowerShares filed a form N-1A registration statement with the SEC to list an exchange traded fund (ETF) with exposure to the S&P 500 with downside exposure actively hedged through VIX futures contracts. The PowerShares S&P 500 Downside Hedged Portfolio (PHDG) seeks to "achieve positive total returns in rising or falling markets that are not directly correlated to broad equity or fixed income market returns" and has annual operating expenses of about 39 basis points....
The Effects of ETF Turnover
(Oct 2012)
Lately there has been a lot of turnover in exchange-traded funds (ETFs), as we noted back in August. InvestmentNews has a great summary of what has happened this year, with 86 funds having closed so far in 2012. They note the important consequences of an ETF closing for investors and advisers:
Even though they are more routine, ETF closings still can create ripple effects that reach financial advisers and their clients. "For an adviser, the worst thing that can happen is, you recommend an ETF...
Two New Exotic Products from the CBOE
(Oct 2012)
The CBOE has begun the offering process on two new and highly innovative volatility-related products that could have broad implications for the exchange traded products market and index investing in general.
The new S&P 500 Variance Futures are futures contracts on the realized variance of the S&P 500 index. This is in contrast with VIX futures, which trade on the impliedvolatility of the S&P 500; however, according to a CBOE press release, the ability to combine the two may have motivated...
