Misrepresentation of Asset Quality in RMBS
(Jul 2013)
Investors in Residential Mortgage Backed Securities (RMBS) have suffered tremendous losses since 2007. Many junior and mezzanine investors were wiped out by the asset pools' delinquency rates coupled with the subordination embedded in these structured securities. Since then, there has been a proliferation of litigation alleging that the underwriters and originators of RMBS misrepresented the risks of these products. An interesting new paper by Professors Piskorski and Witkin of Columbia...
Similar Structured Product Premia in US and Europe
(Jul 2013)
One point we've made again and again in our research is that structured products -- debt securities with market-contingent payoffs -- tend to be priced at a premium to face value. We have documented premia in reverse convertibles, autocallables, absolute return barrier notes, principal-protected notes, dual directionals, and over 17,000 individual products freely available in our searchable structured product database.
Recently, the SEC has required structured product issuers to disclose an...
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...
Structured Investments Linked to Proprietary Indices
(Jun 2013)
Structured products are often linked to well known indices like the S&P 500 or the Dow Jones Industrial Average, but recently it has become more and more common for banks to issue structured investments linked to proprietary indices that they create themselves. The use of proprietary indices (also known as 'self-indexing') has begun to arouse suspicion from various sources and so we thought we'd take a step back and talk about the issue for a moment.
Structured products linked to well-known...
Reverse Convertibles and Event Risk
(Jun 2013)
Reverse convertibles are short-term debt securities issued by banks whose return of principal at maturity is contingent upon the returns of the linked stock. Although these notes typically pay relatively high coupons, they expose investors to losses on the underlying asset, especially if those losses are beyond the trigger level. Academic research shows that these coupons are not adequately compensating the investor for the market risk that they are bearing by investing in the notes. For...
Dodging Hedge Fund Requirements: The Case of Mariner Access
(Jun 2013)
Nowadays, there are several ways that retail investors can purchase risky investments which would typically be considered unsuitable. For example, many exchange-traded funds (ETFs) use derivatives to offer investors access to risky asset classes (such as CDOs) or complex options positions (such as covered calls). Since ETFs can be bought and sold like any other listed stock, essentially any investor can now take covered call positions regardless of her understanding of options. There is even...
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...
New Study Comparing Indexed and Actively Managed Funds
(Apr 2013)
NerdWallet, a San Francisco based personal investing site, has performed a historical study of the returns on almost 8,000 mutual funds and ETFs over a ten year period and found that passive indexed funds tend to outperform actively managed funds on average. In fact, they found that only 24% of actively managed funds outperformed the average return of the indexed funds. These results are consistent with the annual SPIVA Scorecard produced by S&P Dow Jones Indices, which found in both 2012...
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...
